Document Summary
N170 was enhanced and delayed to inverted bodies and faces but not to objects. Human body: tool for achieving a large array of goals, unique medium of emotional expression. Study of emotional communication in humans confined on the study of isolated facial expression. Central theme in face perception research: are there specialized processing routines for faces: role of configural processing routine. Assumption: perceptual routines for faces vs. recognition of non-face objects: faces are recognized based on information provided by the overall configuration (facial parts occur, recognition of non-face objects relies on recognition of isolated parts. Most important source of evidence for the configural processing hypothesis: face-inversion effect refers to the classical finding that face recognition is impaired if faces are presented upside down. Recognition is disrupted much more for faces than for objects and this is manifested in a face-sensitive erp (event related potention) called n170. Expectation: modulation of body expressions can be studied at an electrophysiological level.
