Gender differences in electrophysiological responses to arousing positive and negative stimuli

Over the years studies have described the relationship between sex and emotional processing, specifically the differences in the electrophysiological activity of males and females. A great part of this evidence has been collected using self-report methods in response to the presentation of different emotional stimuli. In order to study the neurological aspect of emotional processing, a study was carried out that used electroencephalography (EEG) to observe the neural changes elicited upon the presentation of neutral, erotic, and mutilation stimuli of 40 participants (20 males, 20 females).
