This is the second book in the Counterpoints series and focuses on alternative models of visual-spatial processing in human cognition. Over the last twenty years, theories and research relating to visual-spatial cognition have been of central interest to a broad range of psychologists - in areas of perception, memory, neuropsychology, and problem solving. This book offers extended chapters from three of the most respected and recognized investigators in the field: Michel Denis, Margaret Intons-Peterson, and Philip Johnson-Laird. The arguments are integrated, and ideas for new directions and new research are offered.
