The human amygdala in social judgement

Article Abstract:

The human amygdala appears to be important in making accurate social judgements using facial appearance to assess individuals. Three subjects with bilateral damage to the amygdala were found to assess faces more positively than controls in terms of trustworthiness and approachability. The difference in assessment was greater when faces were seen by controls to be least trustworthy and approachable. The three subjects performed normally in assessing verbal descriptions of individuals. The amygdala seems to be a major part of neural systems involved in retrieving knowledge using facial appearance.

A mechanism for impaired fear recognition after amygdala damage

Article Abstract:

A report is specified about a patient who suffers from unique bilateral amygdala damage which indicates a conspicuous impairment in her capability to identify fear from the expressions of the face. However, a mechanism is identified to clarify the amygdala's function in fear identification and spots the novel advancements for probably healing the patients with defective emotion perception.

Recognizing facial emotion

Article Abstract:

An analysis of the data obtained from two men who survived herpes simplex encephalitis explain the role of amygdala in the experience and expression of emotion. In adults, amygdala is not solely responsible for the detection of facial emotion. Actual experience of fear is not necessary in evaluating the recognition of fear.
