People often seek techniques that can enhance their learning and retention of important materials. Whereas popular techniques focus on how to increase the effectiveness of memorization by using mnemonics, the self-monitoring approach attempts to enhance people’s learning vis-à-vis the use of accurate monitoring to regulate study. As such, this approach may complement existing mnemonic techniques by helping students to identify which materials have not been well learned and hence require further study. The promise of this self-monitoring approach is illustrated by evidence from three independent lines of research, which demonstrate that the use of accurate monitoring can improve learning for individuals with varying abilities and across different kinds of material.


Evolution, Culture and the Processes of Learning and Memory

Kathleen Heath, Ph.D.

Larry Gant, Ph.D.
University of Michigan

Methods and technologies for enhancing cognitive learning and memory abilities have exploded in the last ten years. However, the potential benefits of cognitive aids may exceed the actual outcome because of a lack of under-standing about how people learn and remember based on our evolutionary adaptation to a hunter-gatherer way of life and our adaptations to particular cultures. Here we discuss the value of understanding our adaptive ancestral self and the role of culture in developing an agenda for individual learning and memory strategies.

What Aspects of Their Memories do People Most Want to Improve?

Kenneth Higbee, Ph.D.
Brigham Young University

There has been much research on how often people experience specified memory problems. This research investigated the importance, rather than the frequency of occurrence, of everyday memory problems by asking people in memory-improvement classes what aspects of their memories they most want to improve. Remembering people’s names was the most important aspect and remembering everyday tasks was more important for females than for males. Other aspects of memory also showed gender and age differences.

This article proposes a new approach for the use of artificial neural net-works in the modeling of cognitive brain functioning. Early artificial neural network models began modeling cognitive function at the neural level using one computer to process all algorithms. The complexity of the neural system in most species suggests that a more realistic approach to modeling cognitive function would be to design a system with multiple artificial neural networks distributed over multiple computers. In this approach each computer in the distributed network would serve a particular function. The goal of this research is to determine a preferable configuration of computer hardware resources and will eventually enable tests of rival theories of cognition and of treatments for neurological disorders.

Defenders of advertising often insist that advertisements serve an in-formational function. The present work explores the use of misinformation in advertising as a means of distorting memory. We review recent work on memory and advertising that demonstrates the malleability of memory after exposure to advertisements containing misleading in-formation. Memory distortion can readily occur for products whose features are hard to verbalize (e.g., the taste of orange juice or wine, the smell of coffee, a theme park vacation). Such memory distortion may compromise one's ability to effectively evaluate products, especially in cases where memory is vital to the evaluation. We argue that misinformation in advertising can distort memory, possibly undermining the informational value of such advertising.

Using the Self-report Free Recall Technique to Explore Everyday Memory Failures in the Aging Adult.

Gabrielle Osborne, M.A.
Claremont Graduate University

Memory failures are lapses in cognitive performance that occur in everyday life. In a laboratory setting, older adults show a decline in memory skills (e.g., Burke & Light, 1981; Park et al., 1996) and therefore they may experience more memory failures in a non-laboratory environment. Self-report questionnaire assessments, however, have shown that older adults experience fewer memory failures. The current study used a self-report free recall interview to gather data on the types and reasons for memory failures participants experienced in everyday life. This technique also allowed an observation of any autobiographical reminiscence bump in the recall of memory failures.

Articulatory Suppression in Bilingual and Second Language Speakers

Mary Flaherty, Ph.D.

Aidan Moran, Ph.D.

There is variation in the literature as to the effect of articulatory suppression on numeral span performance in bilinguals. This study attempts to address these differences by considering the influence of the different definitions of bilingualism and the effect of orthographic variables. The language proficiency in English and Japanese of 39 participants was assessed by measuring their reading rate for both numerals and digit words in the two languages. Those who had learned both languages as children and who spoke both languages daily were “bi-lingual” (n=20), and the others (n=19) who were native English-speaking learners of Japanese were “second-language learners” (L2). Memory span was obtained for numerals and digit words in both languages, under normal and articulatory suppression conditions. The bilinguals’ numeral span advantage in English was eliminated under suppression. L2s showed a superior performance in English in both numerals and digit words in the normal and suppression memory tasks. Memory span on Arabic numerals and Japanese digit words (written in kanji) were similar for both groups of participants, thus suggesting the importance of orthographic features on memory span

We evaluated a new rating method that allows patients to express their recalled pain as a profile of percentages over different intensity levels rather than by using more traditional category scaling methods. Patients in chronic pain generated percent-ages of time they experienced pain by adjusting the heights of four bars, displayed on the computer, representing four levels of pain intensity (none, some, moderate, extreme). The bars were dynamically linked to each other so that changing the height of any one of them simultaneously changed the heights of all the remaining ones in the opposite direction. Cluster analysis identified and separated the patients into three groups, each characterized by a distinct pain profile.

The Focus on Cognition in the Psychopathology Literature: A Bibliometric Analysis

June Sprock, Ph.D.

Douglas Herrmann, Ph.D.
Indiana State University

The present review assessed the degree to which cognitive psychology has been applied to the study of psychopathology. Two studies were conducted using bibliometric analyses (i.e., keyword searches) to review the psychopathology literature (1991-1997; 1998-1999). In both, the name of each disorder in the DSM-IV was combined with terms from cognitive psychology in keyword searches of the abstracts provided in the APA’s electronic databases. The cognitive terms were selected to represent basic topic areas in cognitive psychology. Most of the articles referring to the cognitive terms were limited to the literature on certain diagnostic groups and disorders (i.e., cognitive, psychotic, mood, eating, anxiety, and childhood disorders), and there were very few articles that cited some of the cognitive terms (i.e., problem solving, decision making, and reasoning). The second study added an examination of different cognitive approaches in the psychopathology literature. Although neuropsychology and cognitive therapy were mentioned with some frequency in the literature, references to cognitive neuropsychology, cognitive psychology, cognitive theory, or cognitive rehabilitation were rare. Despite limitations of the bibliometric method, the results suggest that some basic topics and some approaches in cognitive psychology have received little attention within the psychopathology literature. Reasons for these findings are discussed and recommendations are made for a systematic evaluation of cognitive functioning associated with specific mental disorders in order to bring about a more complete understanding of these disorders and their treatment.

Critical to meeting the needs arising from the government’s evolving role in our nation’s security is a broader understanding of how to guide, and even change, the interaction between science practice and science policy. From a practical standpoint, it is important that technologies be investigated for their potential applicability to national security. From a theoretical standpoint, the concepts that drive the investigation and development of new technologies and the refinement of emerging technologies must also be identified.

In most visual search experiments, there is only one possible target object or class of objects. The experiment reported here compares performance in these single-target searches against performance when the target can be either of two different stimuli. The targets used in this experiment were color squares. Results showed that conducting two single-target searches is more efficient than carrying out a dual target search. If visual search is driven by a mental template of the object to be found, then searches for two targets may require a very general template, or a pair of templates that are active simultaneously, which apparently produces less efficient search. Many real world search tasks, such as searches of X-ray images by baggage screeners, require simultaneous search for very different targets (“Find any guns or knives or explosive devices.”). This need for generality could result in search that is less directed and therefore less efficient.


Oculomotor Scanning and Target Recognition in Luggage X-Ray Screening

Jason S. McCarley, Ph.D.

Daniel W. Carruth, B.S.

Visual search for a camouflaged target requires effective oculomotor scanning and object recognition. Our studies of eye movement behavior show that as subjects practice a simulated luggage screening task, increases in sensitivity arise from improvements in the ability to recognize targets, not from changes in the effectiveness of visual scanning. Improvements in recognition, however, show only partial transfer following the introduction of novel targets. Results carry implications for the design of screener training and support systems.

When one asks a question such as, “What is the effect of time-on-task on performance?” the answer (e.g., a vigilance decrement) is likely to describe the results for a group of participants without necessarily characterizing the data from any particular participant. We examined the effects of time-on-task on participants who were searching for guns, knives and scissors in X-ray images of suitcases. Although performance did change across the 25-minute test session, the characteristics of this change varied as a function of the sustained-attention skills brought to the task by participants, as measured with a continuous-performance task. These data have implications for selection and training of airport security personnel, for the ways in which scientists address basic questions about the variables influencing performance in dynamic environments, and for the ways in which administrators frame research policy pertaining to complex applied settings.


Stimulus Competition During Perceptual Learning: Training and Aptitude Considerations in the X-ray Security Process

In this paper, we describe an effort designed to understand some of the fundamental perceptual learning processes associated with X-ray security screening. We manipulated the learning environment by varying amount of “clutter” in the training stimuli. We then explored the differential benefits of training threat item detection based upon spatial aptitudes by using test items varying in “occlusion” (X-ray images with/without overlapping items) and “difficulty” (X-ray images varying in amount of distracting clutter). Spatial aptitude differentially influenced learning dependent upon both clutter in the training environment and the nature of the test items. Results are discussed in the context of aptitude-treatment interactions in perceptual learning. Implications for training in the security screener task are drawn.

In this paper we discuss some of the broader research issues surrounding science and society and how to potentially conceptualize some of the research policy decisions related to national security. We describe recent publications on science policy and the practice of science and how it is that the scientific and policy communities must recognize that fundamental scientific research and applied research are not mutually exclusive. We discuss how the framework of use-inspired basic research fits well with current needs associated with science and security and how it is that policy can be devised to support efforts that simultaneously pursue theoretical and practical goals.

Knowledge structures in problem solving for different modes of communication were examined. Groups solved a murder mystery problem either via computer or in person and then rated concepts for relatedness. Individuals also solved the problem and rated the concepts. Performance scores did not differ among conditions. Ratings were analyzed using the Pathfinder scaling algorithm. The Pathfinder analysis revealed that CMC (computer-mediated communication) groups are not at a disadvantage when communicating distantly. Furthermore, results suggest that, overall; group work may be more individual and less synergistic than is generally believed.


Adding Voice to the Lineup and the Confidence-Accuracy Relationship: Tests Using the MSL Lineup

The jury is still out regarding whether adding voice to a lineup improves its performance. Theory and research are in conflict. The confidence-accuracy relationship is also controversial. This experiment tested the effect of adding voice to the video-clips of lineup members in the MSL (Multiple choice-Sequential- Large) lineup and confidence judgements to choices. The MSL lineup is an enlarged sequential lineup that allows witnesses to choose more than once. The author and one of two confederates recruited the witnesses. The confederate was the “culprit” in a target-present or -absent lineup viewed later. The videoclips were either with or without the voice of the lineup member. Confidence judgments were taken for each lineup choice made. Identification accuracy was no better in the culprit-present voice conditions, nor was there less mistaken choices in the culprit-absent ones. However, if the suspect was chosen with a high degree of confidence, the probability of his guilt was greater.

Beyond the Memory Recall: Why dissociations among memory measures may prove useful to ergonomics

Patrice Terrier, Ph.D.
Jean-Marie Cellier, Ph.D.
Université de Toulouse Le-Mirail

A distinction has now sufficiently entrenched the field of memory research that entire books were devoted to it: the distinction between explicit and implicit memory tasks. We propose that an interesting strategy for task analysis in work settings could emerge from this body of data. In this brief note we suggest that the sort of memory task, that is a test manipulation, can recruit specific processing operations conducted at study. This strategy, which extends the logic of dissociation traditionally used both in ergonomics and in cognitive psychology, does not fall into the selective assumption hypothesis, is non-intrusive, and would allow the study of variations in processing operations induced by natural variations in task conditions. We briefly report some results acquired in the context of process control in order to illustrate the reliability of this strategy relying on the manipulation of memory tests.

Specifying User’s Knowledge – A Cognitive Ergonomic View on Designing Information Technology

Gerrit C. van der Veer, Ph.D.
Mari Carmen Puerta Melguizo, Ph.D.
Vrije Universiteit, Amsterdam (The Netherlands)

Whereas, for the human user, the system is a single more or less monolith “thing;” for the designer it is crucial to find out what types of knowledge will be needed and, hence, have to be specified. The aim of DUTCH (designing for users and tasks, from concepts to handles) is to specify all the relevant knowledge a user should possess to use the system. Such a full specification of all aspects of the technology to be (re)designed is what the model calls UVM (users virtual machine) and the main assumption is that it has to be done from the point of view of the prospective user. This paper starts with a brief overview of the DUTCH design approach that focuses on knowledge of the information technology as well as knowledge of the work situation and organization. In the next section we will deal in detail with the types of knowledge users need for adequately working with complex information technology. Next we will show what designers need to consider when focusing on user knowledge and to what extend different user roles make a difference for design. In the last section we will highlight detail design of information technology, which, in the DUTCH approach, means modeling the user’s virtual machine. To this end we will propose a modeling language NUAN (new user action notation) and provide an example of how NUAN captures the specification of technology details as far as relevant for user understanding.

This study investigated the acquisition of computer skills in relation to computerized memory training in a sample of middle-aged and older adults. Computer skills included mouse use, navigation through the training CD, and autonomy of the training sessions and were assessed in twelve training sessions. Participant characteristics, including prior computer use, were non-significantly associated with acquisition of computer skills over either the first or second half of the training sessions. Acquisition of computer skills was differentially associated with memory performance within training sessions and cognitive performance assessed at posttest. Skills acquisition and performance relationships also differed between the first and second training intervals. Findings suggest that acquisition of computer skills is not a barrier to computerized learning and that novel interventions can be offered to individuals of various ages and computer skill levels. Additionally, computer learning early in the training is a more salient factor in memory improvement than are skills acquired in the second half of the training. Results offer implications for the design and evaluation of computerized training programs.

A Cognitive Learning Principle Derived from the Role Acquisition Strategies of Professional Actors

Tony Noice, Ph.D.
Indiana State University

Helga Noice, Ph.D.
Elmhurst College

In recent years, a wide variety of active learning techniques such as “Cooperative Learning” have been proposed and implemented. This article describes a new active learning device based on the role-acquisition strategies of professional actors. The “Active Experiencing Principle” (AE) bypasses deliberate memorization. In fact, participants are specifically instructed not to memorize but to deeply experience the communication of the to-be-learned material, either in their imaginations or with a partner. The background of the principle is presented, along with evidence of its effectiveness in terms of accurate recall of both words and meaning. Furthermore, the use of the technique to enhance overall cognitive and affective functioning is discussed.

Operationalizing Cognates and False Cognates: Using Translation Elicitation to Generate Stimuli in Six Languages

Brian M. Friel, M.S.
Richard Jackson Harris, Ph.D.
Kansas State University

An empirical method of generating words that were either cognates or false cognates to English in six other languages produced a database of words usable as stimuli in a variety of research paradigms in the study of bilingualism and language learning. The translation elicitation task investigated the guessing of word meaning in six languages (Experiment 1: German, Icelandic, Croatian; Experiment 2: French, Portuguese, Spanish). Native English speakers ( N = 298) guessed the meanings of 100 nouns from a language unknown to them. Guesses for words containing non-English characters (e.g., ß, ç) were less accurate than for other words, although pronunciation guides for each language reduced the differences between conditions in Experiment 1. Data were used to empirically identify words that were cognates or false cognates with English words for possible use in other research. Overlap scores across translations reliably predicted cognate status. Differences across languages were interpreted in terms of etymological distance from English, orthographic depth, and special character prevalence.

Bartering Our Attention: The Distraction and Persuasion Effects of On-Line Advertisements

Brad J. Sagarin, M. Anne Britt, Jeremy D. Heider, Sarah E. Wood, and Joel E. Lynch, Northern Illinois University

New marketing models enable consumers to choose between paying money for products for receiving ad-sponsored versions. Two experiments examined whether these ad-sponsored products represent reciprocal exchanges of desired goods for consumer attention, as perceived by marketers, or giveaways of desired goods at no cost whatsoever, as perceived by consumers. Participants solved anagrams on a computer in the presence or absence of small, static, visually peripheral advertisements. Results suggest that although consumers maintain illusory beliefs that they can tune out such ads. The ads have substantial persuasive and subtle distracting effects. Additional results demonstrate that the interference effects of ad competition, recognition and persuasion were reduced by a second ad, but animating the ads partially mitigate this effect. Ads distracted participants by facilitating procrastination (Exp. 2) but also may have aided participants by helping them break mental sets (Exp. 1).


Cognitive Technology and Self-presentation: Perceptions and Self-Perceptions of Users and Non-Users.

Virgil Sheets, Stacy Fox, Carolyn McGuire and Kristy Spindler, Indiana State University

Theoretical models suggest that possessions serve as extensions of the self and are used to communicate a sense of one's self to others. Accordingly, we explored whether technological devices to aid memory are used to reflect the self, one's identity. One hundred forty-one college students served as participants in an experiment and also completed a brief survey. In the experiment, participants viewed someone who recorded a phone number in a planner, a cell phone, or a palm-pilot, and reported their perceptions of him. In the survey, participants reported their own use of these devices and rated themselves on a set of personality traits. The results confirmed that people who use technological devices to aid memory are perceived differently from people who do not use these devices and that some to these differences reflect differences in self-perceptions of users and non-users. These findings support our contention that technological devices such as cell pones and personal digital assistants (PDAs) reveal aspects of the users' identities to others.


When Time Flies: Effects of Skilled Memory on Time Transformation in Rock Climbers.

Matt Canham, University of California, and Jennifer Wiley, University of Illinois at Chicago.

"Flow" is a psychological state in which performers become completely absorbed in their task, actions are performed effortlessly, and the sense of time passage is distorted. A flow state can occur at any level of skill when there is an optimal balance between a perceived challenge and one's skill level. The current research investigates skilled memory, a possible cognitive correlate of time transformation in flow states. Significant differences were found between novice and expert climbers in memory for a climbing route and the probability of experiencing a flow state in the past. Measures taken immediately following climbs also suggested that experts were more likely to experience both flow states in general and time transformation in particular.


A New Telephone Dialer for Severely Motor Impaired Nonverbal Persons and its Psychological and Cognitive Implications.

E. Doherty, S. Ali, D. Baskaradhas, P. Michael, Fairleigh Dickinson University and J. Rizzo, Morris County Family Services

The simple act of making a phone call is impossible for many motor impaired individuals. A device using a sensor switch, electrode and transducer was created which allowed two severely motor impaired subjects to place a call without assistance. The electrode was worn on the forehead and a computer was used to generate an image of a 15 key console (this computer image was then projected on the wall to make it easier to see). The user could select a one button speed dial option or could select numbers individually. Both subjects could operate the phone including the "hang-up" button and the more impaired subject took 30 minutes to make the call and use his voice synthesizer to select groups of text. Although this may sound a bit time intensive, the user was quite motivated as this was the first call he had placed independently in 12 years.


Measuring Invisible Cognitions: A Technique and Applications

Frederick Parenté, Michael Nestor, Eric Stouffer, Jennifer Wingrat, and Tiffany Hiob, Towson University.

Invisible cognitions are perceptions and thought processes that cannot be detected with conventional statistical procedures. These phenomena usually go unnoticed in studies of cognition because the conventional data analyses are insensitive to them. Two experiments investigated the concept of invisible cognitions with a variety of data sets from studies of cognition and memory. In the first experiment, we used data sets where the Pearson correlations among all pairs of variables in the data sets were not significant. This condition insured that the general linear model could not predict any variable from any other. We then analyzed these data with an Artificial Neural Network (ANN) to determine if it could predict one variable from others in the set. The results indicated that the ANN was able to detect relationships among the variables in the data sets that were invisible to the general linear model. In the second experiment, college students rated slides of artwork on five dimensions. Multiple Regression Analysis (MRA) was used to predict one dimension (pleasingness) from the remaining four. Those dimensions that did not predict using the MRA were then used in the ANN model, which produced a significant fit to the data. Predictions of ANN model were validated in a second scaling of the same slides with a different sample of students.


The Influence of Multimodality, Talker Variability and Noise on Immediate Serial Recall

Sonya Sheffert, Megan MacPherson,and Melissa Wilson, Central Michigan University

The purpose of this study was to evaluate the mnemonic effects of audiovisual speech. This is a critical issue in areas such as distance education which rely on televised audiovisual speech. Previous research has demonstrated that the ability to see a talker's face can facilitate speech processing. Other research has shown that dual coding may reduce cognitive load and improve memory for verbal information. The experiments reported here were designed to determine if the advantages of audiovisual interfaces extend beyond perception by improving working memory processing. In Experiment 1, participants completed a memory span task in which lists of spoken words were presented either unimodally or multimodally, by one taker or ten talkers, and at a fast rate or a slow rate. The data showed that under clear listening conditions the presence of a talker's face significantly reduced memory span. Talker variability and rate also affected recall. In contrast, when the auditory signal was slightly noisy (Experiment 2), visible speaker information was no longer a liability. Taken together, the results indicate that engaging student's interest through the use of audiovisual talkers does not automatically lead to better retention of the linguistic content. In some situations, there may be cognitive costs associated with multimodal communicative technologies.


Book Review - Multimedia Design Principles: Maximizing the Utility of "Multimodalities" When Implementing "Multi-media"

Sandro Scielzo, and Stephen M. Fiore, University of Central Florida

Review of Multimedia Learning by Richard E. Mayer

With ever-increasing popularity in educational and training settings, multimodal presentations are used to convey instructional material. The advances and availability of modern technology seem to have changed the learning experience radically. However, how well can a multimedia presentation efficiently translate into effective multimedia learning? Richard Mayer methodically explores this question, and with the clarity of a true empiricist, he informs the reader on the most current theory and research. In turn, an important conclusion emerges: Effective multimedia presentation must be based on solid design principles that are modeled after the learner's cognitive abilities. In this review we first summarize the critical points from this important book and then we discuss some remaining issues not explicitly addressed.

Design Activities: How to Analyze Cognitive Effort Associate to Cognitive Treatments?

Nathalie Bonnardel and Annie Piolat, University of Provence

Working memory issues are important in many real-life activities. Thus, measuring cognitive effort (or mental load) has been a main research topic for years in cognitive ergonomics, though no consensual method to study this aspect has been proposed, in addition, we argue that cognitive effort has to be related to an analysis of the evolution of cognitive procedss3s (or "time processing"). From this perspective, we present and discuss experimental procedures that have been used for years to study writing activities. In experiments reported in this paper, these procedures are used for studying design activities, in the context of computer graphics and we site design.


Memory of Past Designs: Distinctive Roles in Individual and Collective Design

Françoise Détienne, EIFFEL Research Group "cognition and Cooperation in Design" INRIA

Empirical studies on design have emphasized the role of memory of past solutions. Design involves the use of generic knowledge as well as episodic knowledge about past designs for analogous problems: in this way, it involves the reuse of past designs. We analyze this mechanism of reuse from a socio-cognitive viewpoint. According to a purely cognitive approach, reuse involves cognitive mechanisms linked to the problem solving activity itself. Our socio-cognitive approach accounts for these phenomena as well as reuse mechanisms linked to cooperation, in particular coordination, and confrontation/integration of viewpoints.


Delete Memories: Learning Through Deliberate Forgetting.

Oronzo Parlangeli, Francesca Rizzo, University of Siena and Sebastiano Bagnara, Politecnico di Milano

Failures in memory performances tend to be associated with a negative value, forgetting is thus perceived as something to be avo8ided in order to improve both everyday and working activities. Far from being a common sense interpretation this consideration of forgetting has also characterized most of the scientific literature on forgetting. But, as in everyday life we are frequently unable to process all the information available to us, it seems that some type of forgetting of information is necessary. In fact, most of the time people have to replace old information with new as the contest changes. The present work focuses, through a series of theoretical reflections, on the positive role of forgetting. By doing so the article presents many experimental investigations that might contribute to a new hypothesis of forgetting as a way to better design and implement training activities in contests that are characterized by high levels of uncertainty due to sudden environmental changes.


The Representation of context in the Simulation of complex Systems

Patrizia Marti and Petra Scrivani, University of Siena

This paper moves from the recognition of the importance of the role of context in determining human action. By context we mean social and cultural properties of an environment as defined by activity theory (Kaptelinin, 1996). According to activity theory, human beings live in an environment that is meaningful in itself. This environment consists of entities that combine all kinds of objective features, including the culturally determined ones, which, in turn, determine the way people act on these entities. This notion of context is fundamental for understanding the role of artifacts in mediating human action. In the paper, we adopt the activity theory framework to reflect upon how to represent "the context" for accessing the impact of new technologies in complex systems like air traffic control (ATC)/. Nowadays. The validation of such technologies is mostly performed through the simulation of the operational environment, where controllers perform their activity as if they were in a real situation. We describe an experience we made simulating the activity of an air traffic control tower in managing aerodrome traffic. The simulation was carried out using structured scenarios to represent activities really observed in the control tower and adapted to fit the context of simulation (more advanced control tools, subset of controllers working together). These scenarios offered a valid contribution toward the representation of the context on complex systems like ATC. They successfully contributed to recreate realistic situations where the system components were subject to the full variability of input data and situations that may occur in the real world. Through the description and discussion of the case study, we argue that social and cultural properties of the context need to be represented and analyzed, as well as the physical and cognitive aspects of the human-system interaction. The analysis of these properties can be beneficial in particular for assessing the impact of the introduction of new technology or the application of new operational concepts on safety.


Differential Roles for Visuospatial and Verbal Working Memory in the Construction of Mental Models of Physical Systems.

People use mental models while interacting with physical systems. Designers have been using knowledge elicitation techniques to inf3er user's mental model in order to design interfaces compatible with it. However , to use those techniques correctly we need to define a model that shows how mental models are constructed and simulated during the execution of the elicitation task, Cañas and Antoli (1998) proposes that a mental model is a dynamic representation created in working memory (WM) by combining information stored in long-term memory (the user's conceptual model of the system) and characteristics extracted from the environment. This paper describes an experiment that analyzes the role of the WM components in the construction of mental models. It is concluded that both structure and function information of mental models is processed at the visuospatial component of WM. In addition, data supports the idea the function information is also processed at the verbal component of WE. Finally, some theoretical and practical implications for research on mental models and the use of knowledge elicitation techniques are discussed.


Organizational Memory: The Product of a Reflexive Activity

C. Sauvagnac and P. Falzon, Laboratorie d'ergonmomie du CNAM-41 rue Gay-Lussac, Paris.

Developing an organizational memory (OM) has become a necessity because of the constant and fast evolution of organizations. OM is the result of the process of organizational learning, defined by its temporal characteristics and by way of its circulation. Building of OM requires a reflexive activity. A Field study suggests that during therapeutic decision making. The reflexive use of criteria is a critical issue allotting values to criteria allows one to build knowledge. Decision making mobilizes knowledge for mutual learning, but also changes knowledge. This mechanism needs tools: organizational tools and reports for keeping track of decisions.

Memory is prone to systematic biases and errors. The present work outlines a proposal for educating the public about memory's fallibility. We discuss the formation of false memories and possible theoretical mechanisms responsible for such errors. We also present some memory concepts that might prove useful to educators and the public alike. We conclude by presenting several ways to teach people to be more skeptical about their own memories.

A considerable body of research has indicated that impairments in the ability to store and retrieve verbal information are common features of schizophrenia. The current paper seeks to discuss how strategies developed for other groups with significant memory loss might be applied to help persons with schizophrenia. In particular we concentrate on strategies yet to be applied to schizophrenia which focus on compensating for memory loss through the use of technologies or external aids. These approaches, in contrast to remediation approaches that are already starting to be applied to schizophrenia, do not aim to repair memory loss but instead seek to help persons live with their deficits by providing them with devices that function conceptually as cognitive prostheses. We propose that such devices, if appropriately configured, could be used to increase medication adherence, reduce behavioral disturbances, assist with cognitive self-monitoring and facilitate work function in schizophrenia. Implications for future research are discussed.

While Bartlett's Remembering (1932) is well known, his books entitled The Mind at Work and Play (1951) and Thinking (1958) have received little publicity. It is shown that, if the three books are considered as a series, a general overview of cognitive psychology emerges that, even though it is not mathematical, is both comprehensive and applicable in practice to tasks ranging in difficulty from simple sensorimotor skills to the solution of major scientific problems.

The current study examined the effect of story affect and story role on participants' memory for characters' sex in news stories. In Experiment 1, participants viewed four nurturing TV news stories, which crossed the sex of the lead character with story affect, where the lead character acted positively or negatively. An opposite-sex supporting character accompanied each lead character. Participants remembered lead and supporting characters' sex best when female lead characters acted negatively. Experiments 2 and 3 replicated the procedure in Experiment 1 using written vignettes with gender-neutral roles. Experiment 2 used a 2-minute retention interval to assess memory and Experiment 3 used a 1-week retention interval to assess schemas. Participants remembered characters' sex best when male lead characters acted positively. Overall, story affect powerfully guided participants' memory for the sex of characters, suggesting a virtuous man gender schema.

Memory Failures in Supermarket Shoppers: Evidence for Age and Gender Differences

Memory failures are a pervasive aspect of everyday experience. Recently Hermann and Gruneberg (1999) advocated a recall-reasons approach to studying memory failures on the grounds that this approach was more likely to capture the range of reasons that individuals experienced in their memory failures. This approach is used in the present study to examine the pattern of memory failures found in shoppers. Shoppers at two different supermarkets were questioned on the number and extent of their shopping memory failures. In both stores it was found that males over 50 years of age reported significantly fewer memory failures than females of all ages and males under 50 years of age. This paper looks for possible reasons for this age-gender interaction.

Up to Forty: Lineup Size, the Modified Sequential Lineup, and the Sequential Lineup
A. M. Levi, Ph.D.

Witnesses were recruited by the author and one of seven confederates, the "culprit" in a target-present or target-absent lineup. The 40-person lineup conditions included a MSL lineup (Multiple-choice, Sequential, Large) with the culprit in the 10th, 20th, or 40th position, and a single-choice sequential lineup. The number of identifications of the culprit in the MSL lineup was unaffected by lineup size and culprit position. While mistaken choices in culprit-absent lineups increased with lineup size, the probability of mistaken identification decreased. Thus, lineups of at least size 40 should be used with the MSL. The number of mistaken choices in culprit-absent single-choice sequential lineups was, however, affected by lineup size. Reasons for the results are discussed.

Can a Computer Interface Support Self-explaining?

Previous research has shown that when an experimenter or a tutor prompts students to self-explain orally, generating such self-explanations is effective for learning. If self-explanations are readily produced by prompting, then it would be trivial to implement an automated prompting system using a computer interface. In an attempt to replicate previous research using a human prompter with spoken self-explanations, two experiments were designed using a computer prompter with typed self-explanations. The first experiment tested the effectiveness of spontaneously typed self-explaining while using a computer interface without prompting. The results showed that the amount of self-explaining was surprisingly low, given the amount observed in past research. Typing seems to have caused the students to paraphrase the materials instead. The second experiment tested the effectiveness of an automatic computer prompter, as compared to a human prompter using the same interface. Automatic prompting was just as effective as human prompting, and prompting did increase the amount of typed self-explanations and learning.

Moss Rehabilitation Hospital

Title VI of The Civil Rights Act of 1964 became the prototype for Section 504 of the Rehabilitation Act of 1973 (Scotch, 1984). This is a comprehensive statute designed to insure that disabled persons are able to acquire rehabilitation training and education, access to public buildings and transportation, and employment opportunities (Kelly, 1982). Congress passed Section 504 in September 1973 to protect individuals with physical and mental impairments. It restricted funding to those institutions that supported discriminatory practices.
One result of this legislation was a change in the student enrollment on college and university campuses. Those with recognizable disabilities became more visible. Such groups were followed in the late 70s and into the 80s by students with learning disabilities who required additional support networks. These cognitively impaired students matriculated into degree-granting programs as well as non-credit courses.

Memory Overload: The Effects of Amount of Information, Rate of Presentation, and Reorganization
David Burrows, Ph.D.
Beloit College

Participants in five experiments were given recognition memory tasks designed to create performance at levels well below optimum. In experiments 1, 2, and 3, expansion of memory lists led to gradual degradations in objective levels of performance and gradual increases in perceived stress and loss of efficiency. In experiment 4, a rate of presentation manipulation lowered performance without affecting the gradual nature of list expansion effects. In experiment 5, reorganization of memory through a deletion procedure led to severe declines in performance that rapidly approached chance levels. The results have implications for understanding which variables lead to rapid onset of memory dysfunction and which variables lead to more gradual performance decrements.

Deficits in awareness are often the sequelae of traumatic brain injury. Development of awareness is a major key to survivors' continued gains in rehabilitation. However, tools are needed to measure and define such development. This paper describes such a tool - the 26-item, untimed Martin Awareness Rating Scale (MARS) used to identify and quantify survivors' Intellectual, Emergent and Anticipatory awareness as applied to four areas of function. The use of both a rating to be completed by clinical team members and a survivor self-rating is described, as are the Awareness Rating Summary form and the Graph of Mean Scores which compile and compare these ratings. Other measures, such as number of "matches," which can be extracted from the awareness rating data are also discussed.

Issues Related to School Re-entry Following Traumatic Brain Injury

DuPont Hospital for Children

Every year in the United States, thousands of children sustain traumatic brain injury (TBI) that result from motor vehicle accidents (MVA), falls, sports injuries, as pedestrians and abuse (Rosen & Gerring, 1986). Statistically, the largest group of individuals with TBI is between the ages of 15 and 24 (Savage, 1991). A major goal for children and adolescents who have sustained a TBI is to return to school. By the time moderately or severely brain injured students return to school they are likely to have endured a lengthy and arduous hospitalization and/or rehabilitation process. Both the survivor of TBI and the family may have undergone many life alterations. Memories, experiences, and expectations may be permanently disrupted.

Cognitive Technology is sponsored by the Society for Applied Research on Memory and Cognition and the Society for Cognitive Rehabilitation. It is currently published by the Practical Memory Institute, a subsidiary of Compact Disc, Inc. and printed at Indiana State University, Terre Haute, Indiana.

Policy-Driven Research: A Growth Area in Applied Cognition
Graham M. Davies, Ph.D.
Leicester University

The new political climate has made policy-driven research one of the major growth areas of applied cognitive psychology. It offers great opportunities for applying psychology, but it also has pitfalls and difficulties. The experiences of the author in learning these lessons the hard way in two major areas of policy-driven research - eyewitness testimony and children in the courtroom - are described. In order to provide convincing and reliable answers, cognitively trained researchers may need to shed their adherence to balanced experimental designs and an exclusive reliance upon quantitative methods, but they should be careful not to lose their integrity.

External Memory Aids and the Use of Personal Data Assistants in Improving Everyday Memory

Two experiments investigated the use of external memory aids among college students. Participants in Experiment 1 reported frequent use of external memory aids, particularly electronic devices (e.g., cell phones, pagers). Experiment 2 tracked two groups of students for 6 weeks. The first group was given personal data assistants (PDAs) to use during the 6-week period. The second group served as controls. The use of PDAs increased memory for telephone numbers and weekly schedules, but did not affect other memory tests. Course attendance records indicated that the PDA group missed fewer days than the control group. These results suggest that students prefer to use external memory aids and that the use of such devices can be linked to gains in everyday memory.

Using methods adapted from cognitive psychology to develop and test survey questions seems to be effective in reducing measurement error associated with questionnaire design problems. Early research into the cognitive aspects of survey methodology was done using household surveys administered by personal interviewer visits. This led to an emphasis on refining and advancing cognitive interview techniques when conducting personal, face-to-face interviews. To some, it intuitively makes sense to conduct cognitive interviews in person (face-to-face) since this mode of administration may lend itself best to studying the response process. This leads some questionnaire design researchers to assume that the planned mode of survey interview (data collection) does not need to match the mode of cognitive interview pretesting. Thus, the protocols used to design pretests in survey research often utilize modes that differ from the mode of survey administration. This paper addresses the theoretical framework underlying cognitive interviews and examines the effects that mode of survey administration can have on the selection of pretesting methods. Emerging laboratory methods used by a variety of statistical agencies and survey research centers are described. Results are presented from collaborative investigations which have sought to develop and demonstrate new laboratory research methods used to design and test survey instruments that are self-administered.

In one experiment we investigated the effect of short-term memory load on an event-based prospective memory task (background task) and on a letter-matching task (ongoing task). Participants were presented with strings of five letters and were asked to decide whether the second and fourth letters in each string were the same or different (letter-matching task). They were also required to press the spacebar whenever one or both of these letters was the letter "B" (prospective memory task). There were eight blocks of 30 trials each. In addition to the ongoing and prospective memory task, at the beginning of each block, participants were required to memorize either 7 digits (high load) or 1 digit (low load) that were to be reported at the end of each block (short-term memory task). That is, although the digits were to be kept in mind during the ongoing task, the STM task (digit recall) was not performed concurrently with the ongoing and the PM tasks. Results showed no effects of short-term memory load on prospective memory performance. However, response times in the ongoing letter-matching task increased with high memory load only in the absence of the PM task. When the PM task was present, response times in the ongoing task slowed down, regardless of memory load. As regards STM performance, digit recall was equally good regardless of the presence of the prospective memory task. Finally, participants were slower to respond in the letter-matching task when the irrelevant letters were Bs (activation of intention effect). These results are relevant to the question of the role of automaticity in the retrieval of intentions. They also point to the importance of determining the nature of the monitoring processes that support performance in different prospective memory tasks.

Effects of Mild Alcohol Intoxication upon Driver's Eye Movements

How much alcohol does it take to meaningfully affect your driving performance? While high levels of alcoholic intoxication clearly impair driving performance, what is the effect of consuming an amount of alcohol that many states consider within the legal limit? In this study, sober individuals and mildly intoxicated individuals were shown scenes taken from the perspective of a driver while their gazepoints were recorded. Subjects with blood alcohol levels between .06% and .1% BAC showed meaningful changes in how they scanned scenes when compared with the performance of sober controls. Finally, college-aged subjects reacted to the demonstration of this impairment with surprise and an increased awareness of the seriousness of the problem, suggesting that eyegaze technology not only has relevance to cognitive research but to drunk-driving fatality prevention efforts as well.

The Dragonfly Web Pages provide informal science education on the Web, and are among the first educational Web sites guided by cognitive learning principles. The site consists of about 400 inter-linked pages composed of brief, illustrated expository text, interactive decision making games, side bars, links to resources, and instructions for investigators. Visitors make decisions and receive images, sound, and text tailored to their responses. Learning is conceptualized as a process of creating and refining mental representations. The Dragonfly Web Pages are based on six principles: 1) inquiry facilitates learning, 2) informal learning is intentional and goal directed, 3) learning is knowledge dependent, 4) intrinsic motivation is the basis of informal learning, 5) intuitions are educable, and 6) learning is context sensitive. Data from hit counters, visitor feedback, and an observational study provide preliminary evidence of effectiveness. The Dragonfly Web Pages holds promise as a model of informal education on the Web. However, further research is needed.

Myriad contributions of science have positively impacted the survival and recovery of individual patients in need of brain injury rehabilitation. Technology has empowered practitioners to facilitate patient recovery more quickly and empirically. However, the realities imposed by reimbursement structures within a managed care culture can sometimes cause the process to move TOO quickly. This article explores the concern that managed care urgency is deflecting our attention away from the individual patient as a human being. References to ethical principles and hierarchies of personhood are discussed in terms of rehabilitation as a humanistic endeavor. The argument is made that the way in which human functionality is defined is crucial to our battle against complacency and integral to our desire to promote what is right for each patient as an individual.

Two experiments evaluated the influence of a visual collision warning on overtaking manoeuvres in a simulated driving environment. In the first experiment we compared two conditions (triangle vs. no collision warning) when driving was the only task. In the second experiment we compared three conditions (triangle vs. stop vs. no collision warning) using a dual task that required participants to perform overtaking manoeuvres while computing mental additions. In both experiments participants benefited from collision warning. The results indicate that collision warning signals may improve driving and should be investigated in actual driving conditions.

Many brain injured patients suffer from deficits in executive functions. Their complaints may include difficulty thinking as quickly as they had premorbidly, thinking flexibly and abstractly, and readily generating ideas. Neuropsychological test measures which assess verbal abstraction (e.g., WAIS-III Similarities subtest) and capacity for flexible thinking or generating alternative hypotheses when problem solving (e.g., Wisconsin Card Sort, Category Test) may not necessarily reveal problems in these areas.

Current literature identifies community integration and psychosocial/behavioral adjustment as two key areas for assessing quality of life for persons with Traumatic Brain Injury (TBI). Webb, Wrigley, Yoels, and Fine (1995) noted that "individuals with a positive self concept had the highest perceived quality of life." Kozloff (1987) found that individuals with TBI reported a decrease in their social relationships and a feeling of isolation from their peers. Wheman et al. (1993) identified interpersonal relationship problems as one of five categories for job separation for TBI individuals. Finally, Willer, Ottenbacher, and Coadf (1994) noted that community integration is a particular priority in treatment and habilitation of persons with TBI. Consequently, involvement in a community-based intervention which emphasizes building interpersonal and social interaction skills is essential for improved quality of life for TBI individuals.

Even though most older adults maintain a high level of functioning and independence in everyday life, increasing age is associated with poorer performance on many traditional memory tests. Three computerized memory tasks, a traditional list memory task, a more ecologically realistic name memory task, and an object recognition task were used to assess memory functioning within young and older adult samples. As well, self-reported memory functioning was assessed with the Memory Functioning Questionnaire (Gilewski & Zelinski, 1986; Gilewski, Zelinski, & Schaie, 1990) and a computerized Memory Readiness Questionnaire based upon Herrmann's Multimodal Model of Memory (Herrmann, Plude, Yoder, & Mullin, 1999). Thirty young adults and thirty older adults completed the memory battery. Young adults ranged in age from 16 through 27 years of age and older adults ranged in age from 60 through 87 years of age. The older adults resided independently in the community and were paid $10 for their participation. Young adults received course credit for their participation. The demographic characteristics of the young adults and older adults are provided in Table 1.

Increasingly, organizations are turning to groups and teams to solve problems and make important decisions. While research suggests that groups/teams can be productive and effectively solve problems and make decisions (Dennis & Valacich, 1993; Kelley & Thibaut, 1968; Laughlin, VanderStoep, & Hollingshead, 1991; Tjosvold & Tjosvold, 1995), creating and empowering groups/teams alone does not ensure their success.

A review of: Simple Heuristics That Make Us Smart
by Gerd Gigerenzer, Peter M. Todd, and the ABC Research Group
New York, NY: Oxford University Press, 1999

According to Gigerenzer, Todd and others, "The mind can have it both ways" (p. 365). This is clearly the mantra of the research program of the Center for Adaptive Behavior at the Max Planck Institute for Human Development. The book has 18 authors contributing to various chapters on bounded rationality and accurate decision making in deadline-driven real-world complexity. Beginning with an interdisciplinary team including psychologists, sociologists, economists, biologists and others, the group designed and tested a theory that it is possible to make optimal decisions rapidly, accurately and easily. Some parts of the theory can be seen as an extension of Herbert Simon's vision of the mind as being bounded; that the rationality of the mind is limited and that the structure of information in the environment determines what is rational. Other parts of the theory take us into the new territory of fast and frugal heuristics that increase our adaptive intelligence. As we enter into this new territory, we must first slay a dragon. The dragon is the "heuristics-and-biases" program the authors associate with Tversky and Kahneman (l974). The argument is made that they "tainted the idea of simple mental mechanisms by attaching them to the value-laden 'bias' term" and that, "heuristics were often invoked as the explanation when errors . . . were found in human reasoning" (p. 27).

The Relational Nature of Organizational Knowledge

This paper focuses on how organizations maintain the knowledge that enables an organization to conduct a paradigm shift to new conceptual systems of work. There are three types of knowledge that enable change in organizations, with each type of knowledge being relational in nature. The first type of knowledge is the relationship between people in the form of social networks. The second type of knowledge is understanding the relationships between activity systems, how these relationships may be realigned to cope with novelty, and the rhythm of work that maintains the relationships between activity systems. The third type of knowledge is the strategies that enable an organization to maintain the knowledge required to change conceptual systems of work. These three types of knowledge are largely tacit in nature. The key strategy for maintaining these three types of knowledge is interweaving career trajectories that periodically return members to activity systems. Focusing on the knowledge that enables organizations to change provides new insights into organizational learning and organizational forgetting within and across conceptual systems. An area of concern is whether technology is eroding an organization's ability to sustain and renew its network of minds, and thus it's ability to change conceptual systems.

Cyberlink Participant

An adult male with cerebral palsy and a family history of high blood pressure took part in a series of longitudinal studies that used a Cyberlink-Brain-Body-Interface as an assistive technology device. The study investigated the effect Cyberlink would have on blood pressure, pulse, and aspects of cognition. Testing took place at the beginning and end of each Cyberlink recreation and communication task sessions. Blood pressure measurements showed no consistent pattern of change between the beginning of the test session and the end. The pulse showed a consistent decrease during each session. The participant verbalized a sense of relaxation after each session. The participant's speech therapist also indicated that the subject manifested improved quality of speech and decreased stammering.

In this paper we describe an investigation of differences in cue-pattern recognitional strategies among aviators of differing experience levels. Pilots were presented with meaningful and meaningless configurations of instrument gauges. Tests of perceptual knowledge (i.e., recognition memory for the instruments) and conceptual knowledge (i.e., interpretation of the instruments) resulted in performance differences across the differing configuration types. Although more experienced pilots performed better overall, the differences were most pronounced on recognition of meaningful instrument arrays and interpretation of meaningless instrument arrays. Results are discussed in relation to other findings on cue-pattern recognition processes and expertise.

Age and Education Moderate the Effects of Choice on Performance

Enabling individuals to make some choices can enhance their sense of control. Choice may subsequently enhance motivation to act and strengthen internal attributions for performance. Using cognitive and memory tests in Study 1, we examined the notion that choice enhances performance as well as attributions for performance in community dwelling young and elderly subjects. Study 2 examined the effects of choice and control in less autonomous elderly. Results showed that for choice to be effective, individuals must have attained a certain level of education and must enjoy a relatively autonomous life style. Irrespective of its effects on performance, choice enhanced task involvement and strengthened self attributions for performance. Because choice enhances task involvement, it remains an important issue for the elderly.

Using Pleasantness Ratings to Improve Word Identification

The goal of the current research was to statistically combine pleasantness ratings with recognition judgments in order to improve the accuracy of identification for words. Recognition judgments and pleasantness ratings were made separately because previous research and pilot data suggested that explicit measures (e.g., recognition) might guide implicit measures (e.g., pleasantness). To account for individual differences in ratings, a pleasantness deviation score was calculated for each word rated by each participant, which was used with recognition judgments and pleasantness ratings to create an adjusted recognition measure. Adjusted recognition was found to be more accurate than initial recognition when recognition accuracy was initially low (e.g., for new words and high-frequency words).

Memory dysfunction is the most commonly reported problem after traumatic brain injury, stroke, dementia, and old age (Baddelely, Wilson, & Watts, 1995; Parenté & Herrmann, 1996; Parenté & Anderson, 1991). The demand for effective therapeutic interventions with these populations has never been greater. Moreover, a global economy and international business climate places demands on memory never before experienced by professionals (Rose & Nicholl, 1997). This combination of factors has fostered an entire memory training industry. Many memory-training programs use what has been called a stimulation therapy model whereby the therapist, teacher, or memory training provides exercises that are designed to strengthen the mind or speed up the mental processes (Craine & Gudemann, 1982). The assumption is that doing these mental exercises will enhance the person's memory. Further, it is assumed that the strengthening of the mind will carry over into everyday life. Neither of these assumptions has been shown to be true (Carney et al., 1999). The problem is that stimulation therapy alone simply provides mental exercise. It does not teach the person methods on how to remember nor does it provide practice using these strategies in situations that meet individual needs.

A review of: Humane Interfaces. Questions of method and practice in cognitive technology New York: Elsevier, 1999

As part of the Human Factors in Information Technology 13 series, the edited volume, Humane Interfaces. Questions of method and practice in cognitive technology, highlights the central importance of the human factor in all technology endeavors and the necessity of expeditiously changing technology to better fit its users. Through the selection of authors, the editors recognize the need for multidisciplinary approaches and the need for devising approaches that "humanize" cognitive technology. This text is organized around theoretical perspectives, issues of implementation, and applications of technology. However, although the text provides us with a great deal of information, its most valuable contribution is in challenging us to ask questions, different from many that have been raised before, about how people interface with machines.

Memory Theory and the Cognitive Technology of Spatial Methods in Information Retrieval Systems

Electronic archives of images are becoming common and the development of methods to store and retrieve these images is becoming increasingly important. This article explores some of the theoretical and applied issues in the recall of images in memory relevant to the design of database query methods using spatial depiction. We argue that a near-vacuum exists in our understanding of how continuous variables such as location are represented in memory and that theoretical developments are a necessary precursor to the design of new systems. We present our recent research in this area and also comment upon two ancillary issues relevant to this line of research: the question of how we model user strategy and the significance of process theories of memory. We argue that insufficient attention is paid in theoretical psychology to the modelling of strategy and its methodological consequences, and that this shortfall also has serious consequences for the discipline of cognitive technology. In the case of process models, with which our results are consistent, we observe that this model representation in memory and the end-product of encoding differs, and that this has implications for the relationship between encoding methods and query methods in databases.

Children and adults were asked to read aloud words and to name pictures while at the same time they had to remember to press a key whenever a particular target word or a target picture appeared on the computer screen (prospective memory task). At encoding, participants were shown the prospective memory target either as a picture or as a word. At retrieval, the target appeared - as a word or as a picture - among the test items. Results showed that prospective memory performance is better when the prospective cue presented at retrieval overlaps with the format of the target presented at encoding, irrespective of age, indicating that prospective remembering can be largely data-driven in both age groups. Prospective memory performance was significantly higher in adults than in children. Theoretical and practical implications for memory for intentions are discussed.

Cognitive Technology and Criminal Justice: The Police Composite

The criminal justice system must be understood if cognitive technology is to have any impact on police work. The article uses research on the police composite to illustrate this point. Study 1 is a follow-up on 243 cases for which police constructed composites in 1992-93. Fifty-four cases led to conviction, with another 13 still awaiting trial. The composite aided only five cases. Study 2 compared six composites that had aided the case to 27 others that were solved by other means. Research participants attempted to identify each culprit from among eight photos, with the aid of the appropriate composite. Their choices were no better than chance. Study 3 surveyed 95 recent cases of composites. The article concludes that supporting investigative effort is the key to composite effectiveness, but witness memory for real world crimes is a limiting factor.

Computer Technology for Office-Based Psychological Practice: Applications and Factors Affecting Adoption
Michael J. Murphy, Ph.D., ABPP

Select literature on the use of computers in office-based psychology practice for the support of administration and practice management, assessment, and treatment is reviewed. Characteristics of successful applications and the factors that affect adoption are discussed. While computer applications have been used for business and administrative activities and psychological assessment, there is little adoption in office-practice of applications directed at treatment. The task demands associated with psychological services do not take advantage of the capabilities of computers and reveal their weakness. Furthermore, many applications do not fit the task demands of practice or the cognitive structures employed by clinicians. It is concluded that practical and economic factors determine adoption of technology-based applications and that developers of new products should insure that they accommodate to, rather than change, the current structure of practice or the cognitive processing of practitioners.

Aides to cognition may have begun when the first protohumans used some sign or action. Perhaps the first signs were sounds - possibly grunts meaning such things as "Look at me" or "Get away from me!" or "Come here" or "Here is water." Those grunts and others, presumably became stylized over time and developed into language - probably the most important of all cognitive aides. Similarly, gestures representing such notions as "Look there!" or "Come here" were possibly among the earliest cognitive aides.

Brainwave-R is designed for the treatment of cognitive dysfunction after brain injury. It is a very practical therapy tool that primarily uses paper-and-pencil exercises. It can enhance the treatment repertoire, scope and comprehensiveness of facility-based, neurological rehabilitation programs. This research-based program can be used effectively by seasoned professionals and students alike, from any discipline that provides cognitive rehabilitation to adults with mild to moderate cognitive deficits. The program can be modified for use with adults with severe deficits and with children.

Comments on "Why are there Twelve Inches in a Foot?"
John T.E. Richardson, D.Phil.
Brunel University

Nickerson's article in the latest issue of Cognitive Technology is enjoyable but it should be noted that there is a flaw in Nickerson's initial argument about feet and thumbs. Nickerson presents (on page 20) normative data from Gordon et al. (1988) on foot length and thumb width in men and women. He then presents a table of ratios between these quantities. The text implies that he simply took the ratios between the relevant measures. My check of the numbers in the table confirms this. Nickerson's calculations ended up with ratios that are closer to 11:1 than to 12:1, and so he concluded that the origins of having 12 inches in a foot lie elsewhere.

A Rejoinder to Richardson
Raymond Nickerson, Ph.D.

The point Richardson (2000) makes is valid. The ratio of the means of two paired variables is not necessarily the same as the mean of the ratios of the members of the individual pairs. I suppose that one should expect thumb and foot sizes to be positively correlated in the population, although I know of no data on the question and have no guess as to how strong the correlation is. In any case, I am relieved that the results of Richardson's simulation do not show my numbers to be outside the ball park, and that they support the basic point that the actual ratio is likely to be closer to 11-to-1 than to 12-to-1.

Many everyday activities require people to remember the origin of information. Remembering the source of information is essential to such diverse tasks as reciting a poem, composing an argument, and relating an anecdote at a party. The process of remembering the origin of one's memories is called Source Monitoring. Using the
