The Case for Mental Imagery

Front Cover
Oxford University Press, USA, Mar 9, 2006 - Psychology - 248 pages
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.

About the author (2006)

Stephen M. Kosslyn is the Chair of the Department of Psychology, John Lindsley Professor of Psychology at Harvard University, and Associate Psychologist in the Department of Neurology at the Massachusetts General Hospital. His research focuses primarily on the nature of visual mental imagery,visual perception, and visual communication; he has published 5 previous books and over 275 papers on these topics. Kosslyn has received numerous awards, including the National Academy of Sciences Initiatives in Research Award, a Guggenheim Fellowship, and election to the American Academy of Artsand Sciences. William L. Thompson received his BA in psychology from McGill University in 1990 and since then has worked in Stephen Kosslyn's laboratory in the Psychology Department at Harvard University. Using the techniques of positron emission tomography (PET) and functional magnetic resonanceimaging (fMRI), he has worked on numerous neuroimaging studies, investigating primarily visual mental imagery, but also color perception, hypnosis, and mental rotation. He has co-authored over 30 journal articles and book chapters, including extensive reviews and meta-analyses of the visual mentalimagery literature. Giorgio Ganis has a Ph.D. in Cognitive Science from the University of California at San Diego. He is Assistant Professor in Radiology at the Harvard Medical School and Research Associate in psychology at Harvard University. His research has focused primarily on the neuralcorrelates of visual cognition in humans, and he has published numerous scientific papers on this topic. Ganis has received various awards, including a McDonnell-Pew Program in Cognitive Neuroscience Grant.
