The influence of stimulus form on the scalp-recorded “vertex positive peak” (VPP) evoked by images of faces (Jeffreys 1989a) was studied in seven subjects. In separate experiments, we recorded the responses to 2D images of: (1) many different depictions of human faces; (2) the heads of several different species; (3) many familiar non-face objects; and (4) stimuli where the configuration of objects were modified to produce an “illusory” or “non-contextual” subjective impression of a face.
