This second volume in the Counterpoints Series, which explores issues in psychology, child development, linguistics, and neuroscience, focuses on alternative models of visual-spatial processing in human cognition. This text offers extended chapters from three of the most respected and recognized investigators in the field: Michel Denis, Margaret Intons-Peterson, and Philip Johnson-Laird. Denis considers the role of mental imagery in spatial cognition and
topographical orientation; images are viewed as a form of mental representation that is similar to real-world objects. Intons-Peterson examines spatial representation in short-term, or working-memory, considering
the relationship of visual-spatial processes to subjects' expectations and individual differences. Johnson-Laird approaches the issue of visual-spatial representation from a "mental models" perspective, considering the relationship of images to various cognitive events. The editors provide a historical and theoretical introduction; and a final chapter integrates the arguments of the chapters, offering ideas about new directions and new research designs.
