Title: Object-based selection in the Baylis and Driver (1993) paradigm is subject to space-based attentional modulation. Author: Müller HJ, O'Grady R, Krummenacher J, Heller D. Journal: Psychol Res; 2008 Nov; 72(6):609-29. PubMed ID: 18925416. Abstract: Three experiments re-examined Baylis and Driver's (1993) strong evidence for object-based selection, that making relative apex location judgments is harder between two objects than within a single object, with object (figure-ground) segmentation determined solely by color-based perceptual set. Using variations of the Baylis and Driver paradigm, the experiments replicated a two-object cost. However, they also showed a large part of the two-object cost to be attributable to space-based factors, though there remained an irreducible cost consistent with 'true' object-based selection.[Abstract] [Full Text] [Related] [New Search]
