Seeing through illusions

Więcej o książce

In Seeing Through Illusions , renowned scientist Richard Gregory explores what visual illusions can tell us about how our brains perceive the world. Looking at optical tricks and many other extraordinary phenomena, Gregory explains how scientists use these anomalies to peel back the normalprocesses of perception, and to reveal how the brain performs the remarkable feat of representing the real world with the kind of richness and accuracy which we experience--and take for granted--every day. And these visual illusions not only tell us about how our brain works, but they also revealthe brain's evolutionary past. Traces of earlier stages remain buried within our brains like stratified layers, laid down through evolutionary time, and Gregory shows how the study of different kinds of illusions reveals glimpses of these layers. Interweaving science with reflections on art andphilosophy, fascinating psychological case-studies, and some amazing visual phenomena, this book addresses questions about our brains that have puzzled scientists and philosophers for centuries.
