Modeling categorization of scenes containing consistent versus inconsistent objects

摘要: How does object perception influence scene perception? A recent study of ultrarapid categorization (O. R. Joubert, G. A. Rousselet, D. Fize, & M. Fabre-Thorpe, 2007) reported facilitated when scenes contained consistent objects compared to inconsistent objects. One proposal for this consistent-object advantage is that influenced directly by recognition particular within the scene. We instead asked whether a simpler mechanism relied only on without any explicit could explain advantage. combined computational model based global statistics (A. Oliva Torralba, 2001) with diffusion perceptual decision making (R. Ratcliff, 1978). This sufficient account The simulations suggest need not arise from influencing categorization, but inherent certain have diagnostic categorization.
