The convergence of Kuhn and cognitive psychology

Although psychology has been criticized for adhering to outmoded conceptions of knowledge (e.g. logical positivism), the assertion is made that at least one branch of psychology, namely cognitive psychology, is in the position to corroborate and extend contemporary philosophy of science. Kuhn's “learned perception of similarity” and the related notion of exemplar, which serve to exemplify more adequate conceptions of knowledge within the philosophy of science, are shown to converge with cognitive psychology's schema theory. In this way, the schema theory's empirical offspring provide a validation mechanism for Kuhn's notions and thus provide a richer understanding of the scientific enterprise. This convergence is seen as instantiating an epistemological trend towards understanding of limitations and validity of scientific evidence through an understanding of the limitations and validity of the scientist.     

On applying cognitive psychology

Recent attempts to assess the practical impact of scientific research prompted my own reflections on over 40 years worth of combining basic and applied cognitive psychology. Examples are drawn principally from the study of memory disorders, but also include applications to the assessment of attention, reading, and intelligence. The most striking conclusion concerns the many years it typically takes to go from an initial study, to the final practical outcome. Although the complexity and sheer timescale involved make external evaluation problematic, the combination of practical satisfaction and theoretical stimulation make the attempt to combine basic and applied research very rewarding.     

Advertising: The contribution of applied cognitive psychology

This paper looks at the contribution of applied cognitive psychology primarily to the research on advertising. The first issue is to attempt to define and specify the unique contribution of applied, as opposed to “pure,” cognitive psychology to this research area. Next, the issue of the medium of message delivery is discussed. The importance of program involvement and mood impact on memory for advertisements is then reviewed. The major part of the review looks at the influence of humor, sex, violence, and unconventional sex roles in advertisements on their impact on viewer's memory. An attempt is made to document important and replicated findings in this area. Finally, some effort is made to consider future avenues of research.     

Perception without awareness: perspectives from cognitive psychology

Four basic approaches that have been used to demonstrate perception without awareness are described. Each approach reflects one of two types of experimental logic and one of two possible methods for controlling awareness. The experimental logic has been either to demonstrate a dissociation between a measure of perception with awareness and a measure that is sensitive to perception without awareness or to demonstrate a qualitative difference between the consequences of perception with and without awareness. Awareness has been controlled either by manipulating the stimulus conditions or by instructing observers on how to distribute their attention. The experimental findings based on all four approaches lead to the same conclusion; namely, stimuli are perceived even when observers are unaware of the stimuli. This conclusion is supported by results of studies in which awareness has been assessed with either objective measures of forced-choice discriminations or measures based on verbalizations of subjective conscious experiences. Given this solid empirical support for the concept of perception without awareness, a direction for future research studies is to assess the functions of information perceived without awareness in determining what is perceived with awareness. The available evidence suggests that information perceived without awareness both biases what stimuli are perceived with awareness and influences how stimuli perceived with awareness are consciously experienced.     

Simulation systems for cognitive psychology

Three views of the function of computer simulation in cognitive psychology are analyzed. The strong view that computer simulations will produce more rigorously specified theories is seen to be overstating the case. Two more pragmatic views are supported. One looks at computer method as a means of exploring or validating psychological theories. The other looks to computer simulation as a source of useful concepts. Several recent simulation efforts are presented as illustrations of these latter views. After establishing some perspective on the uses of simulation, the discussion turns to psychological simulation languages and to aspects of programming environments that facilitate simulation work. A new simulation language, PRISM, is described. PRISM’s design is intended as a response to some of the issues raised in this paper.     

Memory metaphors in cognitive psychology

In describing memory phenomena in natural language, a spatial metaphor is typically employed. Memories are considered to be objects that are stored in a mind space, and the process of retrieval is conceived as a search for these objects. It is argued that this metaphor has been carried over into many of the popular theories of memory in cognitive psychology and that seemingly diverse theories employ the same underlying set of assumptions. A survey of the analogies that have been used to explain memory is presented and alternatives to the dominant spatial storage and search assumptions are discussed. The spatial metaphor is evaluated, and the role of analogical explanation in psychology is briefly considered. One result of the increasing number of analogical models is the proliferation of hypothetical mental constructs that are only loosely connected to behavioral measures. nt|mis|A number of members of Ebbinghaus Empire at the University of Toronto contributed analogies that are listed in Table 1 and commented on the views expressed here.     

Prominent publications in cognitive psychology

This article identifies the 50 publications in cognitive psychology that were most frequently cited in the professional literature between 1979 and early 1982. The characteristics of these publications are discussed, and comparisons are made with other relevant findings.     

Computer use in cognitive psychology

Some influences of computers on theory and methodology in cognitive research are discussed. Theoretical constructs that cognitive science has borrowed from computer science include processing algorithms, processing rates, information organization, and information selection. The application of these constructs to human information processing is considered, with illustrations from memory and reading research. Further, the role of computers in research methodology is evaluated, on the basis of a comparison of 1962 and 1992 journal articles. Attributes considered include the nature of stimulus control, item content and physical features, cognitive task demands, information feedback to subjects, and assessment of individual differences in cognitive strategies. These methodological attributes are illustrated by memory and reading paradigms for which computer technology is critical. Computer science has enriched theory and data in cognitive science, but the comparison of journal articles from 1962 and 1992 suggests that many psychologists are not taking full advantage of these possibilities.     

Integrating cognitive psychology, neurology and neuroimaging

In the last decade, there has been a dramatic increase in research effectively integrating cognitive psychology, functional neuroimaging, and behavioral neurology. This new work is typically conducting basic research into aspects of the human mind and brain. The present review features as examples of such integrations two series of studies by the author and his colleagues. One series, employing object recognition, mental motor imagery, and mental rotation paradigms, clarifies the nature of a cognitive process, imagined spatial transformations used in shape recognition. Among other implications, it suggests that when recognizing a hand's handedness, imagining one's body movement depends on cerebrally lateralized sensory-motor structures and deciding upon handedness depends on exact match shape confirmation. The other series, using cutaneous, tactile, and auditory pitch discrimination paradigms, elucidates the function of a brain structure, the cerebellum. It suggests that the cerebellum has non-motor sensory support functions upon which optimally fine sensory discriminations depend. In addition, six key issues for this integrative approach are reviewed. These include arguments for the value and greater use of: rigorous quantitative meta-analyses of neuroimaging studies; stereotactic coordinate-based data, as opposed to surface landmark-based data; standardized vocabularies capturing the elementary component operations of cognitive and behavioral tasks; functional hypotheses about brain areas that are consistent with underlying microcircuitry; an awareness that not all brain areas implicated by neuroimaging or neurology are necessarily directly involved in the associated cognitive or behavioral task; and systematic approaches to integrations of this kind.     

Trafficking in cognition: applying cognitive psychology to driving

This paper summarises a Presidential Address to the Division of Traffic and Transportation Psychology at the 2002 International Congress of Applied Psychology. It considers whether traffic psychology is a distinct area of psychology, and concludes that the range of psychological approaches that understanding drivers and traffic requires is too pervasive for it to be so. The difficulties and shortcomings of various attempts to apply cognitive psychology to driving and traffic are explored, with respect to perceptual, motor and skilled aspects of the driving task. Examples are given of how ‘understanding driving’ poses theoretical challenges to mainstream cognitive psychology that have yet to be satisfactorily resolved.     

Social psychology at the crossroads: Its encounter with cognitive and ecological psychology and the interactive perspective

This article discusses the implications for social psychology of recent developments in the neighbouring fields of cognitive and ecological psychology. The authors stress the importance of studying the cognitive processes directly instead of inferring them as hypothetical constructs from aggregate responses. This paradigmatic shift implies a change in the conduct of research from the traditional nomothetic perspective to a neo-idiographic one. A method of representational contextualization is offred to generate the affective and cognitive deep structure from surface, first order data. This structure identified as the internal environment, reflects simultaneously the construction of reality by a situated individual and the recoding rules operating in such a construction.
