Object-based attentional selection—Grouped arrays or spatially invariant representations?: Comment on Vecera and Farah (1994).

S. P. Vecera and M. J. Farah (see record 1994-32352-001) have addressed the issue of whether visual attention selects objects or locations. They obtained data that they interpreted as evidence for attentional selection of objects from an internal spatially invariant representation. A. F. Kramer, T. A. Weber, and S. E. Watson question this interpretation on both theoretical and empirical grounds. First, the authors suggest that there are other interpretation of the Vecera and Farah data that are consistent with location-mediated selection of objects. Second, they provide data, using the displays employed by Vecera and Farah in conjunction with a postdisplay probe technique, that suggests that attention is directed to the locations of the target objects. The implications of the results for space and object-based attentional selection are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
