Imagery In Working Memory And In Mental Discovery

A special issue of European journal of cognitive psychology.

The Baddeley and Hitch (1974) Working Memory model holds a central place in experimental psychology and continues to be extremely successful in guiding and stimulating research in applied and theoretical domains. Yet the model now faces challenges from conflicting data and competing theories. In this book, experienced researchers in the field address the question: Will the model survive these challenges? They explain why it is so successful, evaluate its weaknesses with respect to opposing data and theories and present their vision of the future of the model in their particular area of research. The book includes a discussion of the "Episodic Buffer" component which has recently been added to the working memory model. The result is a comprehensive and critical assessment of the working memory model and its contribution to current research in human cognition, cognitive development, neuroscience and computational modelling. Furthermore, this collection serves as a case study to illustrate the range of factors that determine the success or failure of a theory and as a forum for discussing what researchers want from scientific theories. The book begins with an accessible introduction to the model for those new to the field and explains the empirical methods used in working memory research. It concludes by highlighting areas of consensus and suggesting a programme of research to address issues of continuing controversy. Working Memory in Perspective will be a valuable resource to students and researchers alike in the fields of human memory, language, thought and cognitive development.

Our ability to be conscious of the world around us is often discussed as one of the most amazing yet enigmatic processes under scientific investigation today. However, our ability to imagine the world around us in the absence of stimulation from that world is perhaps even more amazing. This capacity to experience objects or scenarios through imagination, that do not necessarily exist in the world, is perhaps one of the fundamental abilities that allows us successfully to think about, plan, run a dress rehearsal of future events, re-analyze past events and even simulate or fantasize abstract events that may never happen. Empirical research into mental imagery has seen a recent surge, due partly to the development of new neuroscientifc methods and their clever application, but also due to the increasing discovery and application of more objective methods to investigate this inherently internal and private process. As the topic is cross hosted in Frontiers in Perception Science and Frontiers in Human Neuroscience, we invite researchers from different fields to submit opinionated but balanced reviews, new empirical, theoretical, philosophical or technical papers covering any aspect of mental imagery. In particular, we encourage submissions focusing on different sensory modalities, such as olfaction, audition somatosensory etc. Similarly, we support submissions focusing on the relationship between mental imagery and other neural and cognitive functions or disorders such as visual working memory, visual search or disorders of anxiety. Together, we hope that collecting a group of papers on this research topic will help to unify theory while providing an overview of the state of the field, where it is heading, and how mental imagery relates to other cognitive and sensory functions.

Si nce the beginning of the 1970's the psychological study of imagery has shown a renewal of scientific interest reflected in a di verse body of theory, research paradigms, and data, which, with dil1iculty, ean be managed by a reader interested in imagery. Further, ment. al i lllagery appears to be an important construct in fields such as perception, memory, learning, thinking, motor behavior, cognitive development, and so on. With the diversity of theoretical and empirical work on imagery, cognition, and performance, it is increasingly problemut. ic to find a single source that provides contemporary overviews ill each field. Our purpose in organizing this book was to attempt all IIp-Lodate presentation of imagery research and theory. It is ollr hope that the volume will help serve as a starting point for the progress that will surely appear in the 1990's. This book hi:\:; its roots in the Second Workshop on Imagery and Cognition held at the University of Padova, Padova, Italy from September 21 to September 23,1988. An impressive array of research was presented at the workshop, and as the workshop unfolded several salient point. s elllerged. Though the research was diverse, it was even more so convergent on several main themes (e. g. , relations betweeen imagery and perception, imaginal coding in working memory, the role of imagery in v(;rbal memory and in memory for action events, imagery and problem solving).

The nature of mental images and their relation to language has caused controversy amongst psychologists for years, and the so-called "imagery debate" is still unresolved. Fresh light is now being shed on this topic using recent findings in neuroscience and the development of behavioural studies. Reviewing state-of-the-art research in the field of imagery, visuo-spatial memory, spatial representation and language, with special emphasis on their interactions, the volume shows how, and to what extent, findings from the studies on imagery can positively influence and enrich other psychological areas such as: Working memory Space and time representation Language and embodiment Chapter 9, written by Michel Denis, to whom this book is dedicated, analyses more than three decades of research, and outlines the shared scientific journey of friendship and discovery that has developed across various cognitive topics, all of which are linked to, and inspired by, imagery conceptualization. This is the only book to present a critical outline of research on these topics in a single volume, and as such will be invaluable to advanced undergraduates, postgraduates and researchers in such fields as cognitive psychology, neuroscience, computer science and neuropsychology.

Representation of the visual and spatial properties of our environment is a pivotal requirement of everyday cognition. We can mentally represent the visual form of objects. We can extract information from several of the senses as to the location of objects in relation to ourselves and to other objects nearby. For some of those objects we can reach out and manipulate them. We can also imagine ourselves manipulating objects in advance of doing so, or even when it would be impossible to do so physically. The problem posed to science is how these cognitive operations are accomplished, and proffered accounts lie in two essentially parallel research endeavours, working memory and imagery. Working memory is thought to pervade everyday cognition, to provide on-line processing and temporary storage, and to update, moment to moment, our representation of the current state of our environment and our interactions with that environment. There is now a strong case for the claims of working memory in the area of phonological and articulatory functions, all of which appear to contribute to everyday activities such as counting, arithmetic, vocabulary acquisition, and some aspects of reading and language comprehension. The claims for visual and spatial working memory functions are less convincing. Most notable has been the assumption that visual and spatial working memory are intimately involved in the generation, retention and manipulations of visual images. There has until recently been little hard evidence to justify that assumption, and the research on visual and spatial working memory has focused on a relatively restricted range of imagery tasks and phenomena. In a more or less independent development, the literature on visual imagery has now amassed a voluminous corpus of data and theory about a wide range of imagery phenomena. Despite this, few books on imagery refer to the concept of working memory in any detail, or specify the nature of the working memory system that might be involved in mental imagery. This essay follows a line of reconciliation and positive critiquing in exploring the possible overlap between mental imagery and working memory. Theoretical development in the book draws on data from both cognitive psychology and cognitive neuropsychology. The aim is to stimulate debate, to address directly a number of assumptions that hitherto have been implicit, and to assess the contribution of the concept of working memory to our understanding of these intriguing core aspects of human cognition.

What factors affect creativity and the generation of creative images? What factors affect the ability to reinterpret those images? Research described in this book indicates that expectations constrain both of these attributes of creativity. Characteristics of the imagined pattern, such as cohesiveness or its psychological goodness, also affect image generation and reinterpretation. Other evidence indicates that images can be combined mentally to yield new, manipulable composites. Cognitive models encompass the research and extend it to fields as diverse as architecture, music, and problem solving.
