Towards an analytic framework for the visuospatial domain: Spatial reference frames, cognitive operations, and neural systems

This article addresses the confusion in neuropsychological literature on vi suospatial function and then proposes an analytic framework towards resolut ion in the visuospatial domain. Three bodies of literature on visuospatial processing are summarized, and from each is derived an analytic dimension f or visuospatial investigation. They are: (1) the frame of space (e.g., egoc entric), (2) the definition of spatial operations in cognitive terms, and ( 3) spatial processing in terms of neural hierarchy and respective neural ce nters. It is proposed that these dimensions can constitute a working model to clarify the complexity of visuospatial function.
