بررسی رابطه بین تشخیص احساسات چهره، خود کنترل و صفات روانی در یک نمونه غیر بالینی

Although psychopathy is a low prevalence disorder, individuals with sub-clinical psychopathic traits have been shown to reside within the community. One account of psychopathy proposes that deficits in self-control play a causal role. Other theorists propose that psychopathy-related antisocial behaviour can be attributed to a constitutional deficit of empathy, resulting from an inability to interpret and respond to the affective cues of others. These theoretical perspectives may both be relevant if psychopathy is understood as a dimensional construct, with primary psychopathy the consequence of a neurological vulnerability to emotional deficits, and secondary psychopathy reflecting an environmental adaptation and subsequent failure of self-control. Using a non-clinical sample (n = 479), this study examined the relationship between sub-clinical psychopathic traits, self-control and the identification of facial emotion. Both primary and secondary psychopathic traits were associated with reduced accuracy in identifying facial affect, with more pronounced impairments seen for primary psychopathy. While both primary and secondary psychopathic traits were found to be related to deficits in dispositional self-control, the effect was significantly greater for secondary psychopathy.
