The locus of concreteness effects in memory for verbal materials has been described here in terms of the processing of shared and distinctive information. This theoretical view is consistent with a variety of findings previously taken as support for dual coding, insofar as both verbal and perceptual information may be involved in comprehending high-imagery sentences and in learning lists of concrete words. But going beyond previous accounts of imagery, this view also can provide explanations for several findings that appear contradictory to the thesis that concrete and abstract materials differ in the form of their storage in long-term memory. Although this does not rule out a role for imagery in list learning or text comprehension, it is clear that the complex processes involved in comprehension and memory for language go beyond mechanisms supplied by a theory based on the availability of modality-specific mental representations. The task now is to determine the viability of the theory in other domains. Several domains of imagery research presented at EWIC provided fertile ground for evaluating my theoretical viewpoint. Although not all provide a basis for distinguishing representational theories of imagery from the imagery as process view, there are data in several areas that are more consistent with the latter than the former. In other cases, there are at least potential sources of evidence that would allow such a distinction.
The relationships between perception and imagery, imagery and spatial processes, memory and action: These are the main themes of this text The interest of experimental psychology and cognitive neuroscience on imagery and spatial cognition is remarkably increased in the last decades. Different areas of research contribute to the clarification of the multiple cognitive processes subserving spatial perception and exploration, and to the definition of the neurophysiological mechanisms underpinning these cognitive functions. The aim of this book is to provide the reader (post-graduate students as well as experts) with a complete overview of this field of research. It illustrates the way how brain, behaviour and cognition interact in normal and pathological subjects in perceiving, representing and exploring space. (Series B).
Today in many studies, mental images are still either treated as conscious by definition, or as empirical operations implicit to completing some type of task, such as the measurement of reaction time in mental rotation, an underlying mental image is assumed, but there is no direct determination of whether it is conscious or not. The vividness of mental images is a potentially helpful construct which may be suitable, as it may correspond to consciousness or aspects of the consciousness of images. In this context, a complicating factor seems to be the surprising variety in what is meant by the term vividness or how it is used or theorized. To fill some of the gaps, the goal of the present Special Issue is to create a publication outlet where authors can fully explore through sound research the missing theoretical and empirical links between vividness, consciousness and mental imagery across disciplines, neuroscience, psychology, philosophy, cognitive science, to mention the most obvious ones, as well as transdisciplinary methodological (single, combined, or multiple) approaches.
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).
When we try to remember whether we left a window open or closed, do we actually see the window in our mind? If we do, does this mental image play a role in how we think? For almost a century, scientists have debated whether mental images play a functional role in cognition. In The Case for Mental Imagery, Stephen Kosslyn, William Thompson, and Giorgio Ganis present a complete and unified argument that mental images do depict information, and that these depictions do play a functional role in human cognition. They outline a specific theory of how depictive representations are used in information processing, and show how these representations arise from neural processes. To support this theory, they seamlessly weave together conceptual analyses and the many varied empirical findings from cognitive psychology and neuroscience. In doing so, they present the conceptual grounds for positing this type of internal representation and summarize and refute arguments to the contrary. Their argument also serves as a historical review of the imagery debate from its earliest inception to its most recent phases, and provides ample evidence that significant progress has been made in our understanding of mental imagery. In illustrating how scientists think about one of the most difficult problems in psychology and neuroscience, this book goes beyond the debate to explore the nature of cognition and to draw out implications for the study of consciousness. Student and professional researchers in vision science, cognitive psychology, philosophy, and neuroscience will find The Case for Mental Imagery to be an invaluable resource for understanding not only the imagery debate, but also and more broadly, the nature of thought, and how theory and research shape the evolution of scientific debates.
This book represents the research efforts of individuals whose scientific expertise lies in reflection on what Sartre described as reflective acts. Theory in the cognitive psychology of mental imagery, endeavors not only being able to describe the contents and nature of mental imagery, but also being able to understand the underlying functional cognition. Psychologists need not solely rely on the techniques of introspection, and the last two decades have seen highly creative developments in techniques for eliciting behavioural data to be complemented by introspective reports. This level of sophistication has provided singular insights into the relationship between imagery and other consequential and universal aspects of human cognition: perception, memory, verbal processes and problem solving. The recognition that imagery, despite its ubiquitous nature, differs between individuals both in prevalence and in kind, and the dramatic rise in cognitive science has provided the additional potential for integrating our understanding of cognitive function with our understanding of neuroanatomy and of computer science. All of these relationships, developments and issues are dealt with in detail in this book, by some of the most distinguished authors in imagery research, working at present in both Europe and the USA.
Déjà vu is one of the most complex and subjective of all memory phenomena. It is an infrequent and striking mental experience, where the feeling of familiarity is combined with the knowledge that this feeling is false. While until recently it was an aspect of memory largely overlooked by mainstream cognitive psychology, this book brings together the growing scientific literature on déjà vu, making the case for it as a metacognitive phenomenon. The Cognitive Neuropsychology of Déjà Vu reviews clinical, experimental and neuroimaging methods, focusing on how memory disorders and neurological dysfunction relate to the experience. Examining déjà vu as a memory phenomenon, Chris Moulin explores how the experience of déjà vu in special populations, such as healthy aging or those with schizophrenia, provides new insights into understanding this phenomenon. He considers the extensive data on déjà vu in people with epilepsy, dementia and other neurological conditions, assessing neuropsychological theories of déjà vu formation. Essential reading for all students and researchers interested in memory disorders, this valuable book presents the case for déjà vu as a ‘healthy’ phenomenon only experienced by people with sufficient cognitive resources to oppose and detect the false feeling of familiarity.
This book gives equal weight to the psychological and neurological approaches to the study of cognitive deficits in patients with brain lesions. The result is an analysis of cognitive skills and abilities that departs from the more usual syndrome approach.
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.
