BONILLA, Fidel Mauricio  e  LEONGOMEZ, Juan David. EFFECTS OF THE PRESENTATION OF FEAR AND ANGER EMOTIONAL FACES ON THE AMPLITUDE AND LATENCY OF THE N170 COMPONENT. Psychol. av. discip. [online]. 2017, vol.11, n.1, pp.39-48. ISSN 1900-2386.

The discrimination of emotions expressed by the facial expressions is important for social relationships, empathy and social interactions. The main aim of this study was to study whether there were differences in the cortical processing to two basic emotions, anger and fear, and whether the perception of intense anger generates a higher modulation in amplitude and latency of the N170 component than intense fear. The technique used was event related potentials with a 32-channel montage. We found significant differences in the latency for images of faces expressing intense anger compared to the condition of images of faces of intense fear, as well as differences in amplitude in latency in response to the presentation of neutral faces in comparison to intense anger and fear.
