On Seeing Forms [EPUB ebook] 

Originally published in 1988, this is the final volume in the set. The original intent of the tetralogy was to review neural explanations of high level perceptual and cognitive processes. However, at this point, it became clear that there were few neural explanations of perceptual topics – a situation that still persists today. This book, therefore, used a different framework examining the role of detection, discrimination, and recognition at the behavioral level.
