The brain computations that underlie our ability to recognize facial expressions involve the extraction of relevant information from the faces of our peers, and allow us to readily respond in an appropriate manner to the displayed emotion. Here we present recent advances in understanding the brain processes underlying the categorization of facial expressions of emotion using classification image techniques...
The present study examined the role of high-spatial frequency information in early face processing, as indexed by the N170 face-sensitive ERP component. Participants detected 4 versions of famous faces, including full spectrum faces, and bandpass filtered faces containing predominantly high-spatial frequencies, low-spatial frequencies or both. The power spectra of all stimuli were balanced by superimposing...
Does the perceptual processing of faces flexibly adapt to the requirements of the categorization task at hand, or does it operate independently of this cognitive context? Behavioral studies have shown that the fine and coarse spatial scales of a face are differentially processed depending on the categorization task performed, thus suggesting that the latter can influence stimulus perception. Here,...
