Brain asymmetries in face processing: a critical review of electrophysiological studies from a psychological point of view.

The few studies dealing with physiological (EEG, VEP) brain asymmetries in the processing of faces by neurologically intact subjects are critically reviewed from a psychological point of view. It emerges that a more careful selection of the cognitive tasks is needed, along with more prudent statistical planning. The difficulties of comparing physiological and behavioral asymmetries are also emphasized.
