Résumé
(from the chapter) This chapter has focused on the role of attention in generating analytic representations of object shape. However, numerous other factors are likely to affect whether the visual system will generate an analytic representation of an object's shape, and some of these deserve mention. One is time. Representing an object's shape analytically entails segmenting the object's image into its constituent features or parts. The operations that perform this kind of segmentation depend on lateral communication between neurons representing local features in an object's image, and probably also exploit feedback from representations of known objects to representations of local image features. Such interactions take time and imply that analytic representations cannot be generated in any strictly feed-forward manner. Behaviorally, these considerations predict that recognition based on an analytic representation of shape should take longer than recognition based on a holistic representations. To my knowledge, this prediction remains to be tested. (PsycINFO Database Record (c) 2007 APA, all rights reserved)
