"I can't see your eyes well 'cause your nose is too short" : an interactivity account of holistic and configural face processing

What is meant by configural and holistic processing? The present project attempts to answer this question by formalizing configural and holistic processing as interactive processing of face parts. Four face images were created from one main face by varying the eye distance and nose length of the face to yield a 2x2 feature-complete factorial combination set of stimuli. Participants viewed each version of the face for 100 msecs, and then identified the face they saw. Their responses were subjected to multidimensional signal detection analysis to obtain estimates of different types of perceptual interactions defined by General Recognition Theory (Ashby & Townsend, 1986). It is shown here that perception of upright faces exhibits a number of interactions that are not present for inverted faces. The nature of these interactions are linked to concepts of holistic and configural face processing. A computational justification is forwarded for this interactivity account of face processing.
