[Global predominance in object recognition: artefact or treatment rule?]

This paper provides a critical evaluation of the idea that, relative to the identity of the parts (local aspect), the configuration of the parts (global aspect) is of special importance during perceptual analysis. The controversy surrounding the global precedence phenomenon (Navon, 1977) is reviewed. In particular, I evaluate and reject the hypothesis that global precedence is simply the product of the greater discriminability of the global aspect. Instead, I propose that one general rule characterizing preattentive perceptual processing is a broad categorization of global information. I present the empirical evidence supporting this model and suggest some direction for future studies.
