In this paper we examined the recognition of facial expressions of emotion at normal population and at inmates with mild offenses and at inmates with severe offenses and antisocial personality disorder (APD). Participants were shown images of faces expressing emotions and they were asked to identify the types of emotions expressed. We predicted that the inmates would have difficulties in the process of recognition of the emotions, especially inmates with APD. We compared the accuracy of interpretation of the inmates with the accuracy of the normal population, also between types on inmates, and the results confirmed our assumptions. Our results are consistent with the vast majority of the research on this topic, and we believe that aspects related with the emotional intelligence (EI) are involved in the process of recognition of the emotions transmitted by facial expressions.
