Abstract
Neuropsychological evidence offers a great deal to the understanding of normal cognition. This chapter focuses on the techniques and systematic investigations of both individual case studies and of groups of individuals who exhibit disorders of visuospatial working memory following damage to the brain. It addresses the possibility that working memory is best viewed as a multiple component system, and that within such a system, there might be further fractionation between visual and spatial resources with performance on some spatial tasks requiring the use of executive functions. This chapter talks about the relationship between visuospatial working memory, and other parts of the cognitive system by exploring whether or not visuospatial working memory acts as a gateway between perception and long-term memory. It then considers the impairments of different aspects of visuospatial working memory that arise from the phenomena of unilateral spatial neglect and of cortical blindness.
