    Object shape space

    Traditionally, visual attention has been considered a spatial phenomenon, allocated to contiguous regions in the manner of a spotlight. Accumulating evidence from a variety of sources have challenged this notion and questioned the primacy of spatial location as the form of representation which mediates selection. Evidence for separate space and object-based attentional mechanisms, and the relationship between these mechanisms in typical adults and those with spatial cognition deficits due to congenital disorders will be presented. In contrast to traditional models in which selection is mediated by location, the role of objects and their form in guiding attention will be highlighted.
