1. What are the mechanisms underlying after-effects in the perceptual system? Do you think that these effects represent a fundamental flaw in the perceptual system, or could they have positive value in an evolutionary context?
2. What is ‘feature integration theory’? How well does it account for the processing of features in our visual environment and their perceptual integration? Do you think that this framework could be applied usefully to sensory modalities other than vision?
3.What is ‘blindsight’? What are its implications for our understanding of how vision works? (You will especially need to consult other chapters in this book, and other sources of information – see, for example, the work over the past 25 years of Weiskrantz – in order to address this question thoroughly.)
