Comparing the loci of holistic processing in people and models

摘要: Recognizing faces is thought to rely on holistic processing, where the entire face is recognized as a unitary visual object (eg, Farah et al., 1998). Recent work using analyses from General Recognition Theory (Ashby & Townsend, 1986; GRT) that distinguishes between possible loci of holistic effects has found stronger evidence for a decisional rather than perceptual component (Wenger & Ingvalson, 2002, 2003; Thomas, 2001; Richler et al., 2006); these results introduce important constraints for models of face processing. Using this same GRT framework, the present research identified the loci of holistic processing in simulations produced by one well-known model of face recognition by Cottrell and colleagues (Cottrell et al., 2002) that accounts for the typical kinds of holistic effects observed in people. While this model accounts for holistic effects, is the locus of this holistic processing perceptual or decisional? We …
