'What' and 'Where' in Visual Attention: Evidence from the Neglect Syndrome
Abstract
From what types of visual representations does attention select stimuli for further processing? Two alternatives that have been investigated within cognitive psychology are: Array, or location-based representations, and object-based representations. We briefly review the literature on this issue in normal subjects, and then report two experiments on the same issue using parietal-damaged patients with visual neglect. The findings from neglect patients are then discussed with respect to: The clinical literature on the effects of bilateral parietal damage, and the classical distinction between the spatial functions of the dorsal visual system and the object identification functions of the ventral system.
