چکیده انگلیسی

The authors examined the association between psychopathy and identification of facial expressions of emotion. Previous research in this area is scant and has produced contradictory findings (Blair et al., 2001, 2004; Glass & Newman, 2006; Kosson et al., 2002). One hundred and forty-five male jail inmates, rated using the Hare Psychopathy Checklist: Screening Version participated in a facial affect recognition task. Participants were shown faces containing one of five emotions (happiness, sadness, fear, anger, or shame) displayed at one of two different levels of intensity of expression (100% or 60%). The authors predicted that psychopathy would be associated with decreased affect recognition, particularly for sad and fearful emotional expressions, and decreased recognition of less intense displays of facial affect. Results were largely consistent with expectations in that psychopathy was negatively correlated with overall facial recognition of affect, sad facial affect, and recognition of less intense displays of affect. An unexpected negative correlation with recognition of happy facial affect was also found. These results suggest that psychopathy may be associated with a general deficit in affect recognition.

مقدمه انگلیسی

Psychopathy is a disorder comprised of a unique confluence of affective, interpersonal, and behavioral traits (Cleckley, 1941 and Hare, 1991). Deficient or abnormal emotional experience has long been considered a hallmark of psychopathy (Cleckley, 1941). Research has demonstrated that psychopathic individuals experience emotions differently, showing qualitative and/or quantitative differences in their ability to experience emotion (Hare, 1993, Hare, 1998 and Steuerwald and Kosson, 2000) and process affective language (Gillstrom and Hare, 1988, Hare and McPherson, 1984 and Williamson et al., 1991). Significant abnormalities have also been found in physiological responses to affective material (Hare, 1978 and Patrick et al., 1993) and memory for emotional events (Christianson et al., 1996). Recently, researchers have begun to examine the relationship between psychopathy and identification of emotional states in others. Stevens, Charman, and Blair (2001) examined psychopathic children’s ability to recognize both facial expressions of emotion and vocal tone. Children with psychopathic traits evidenced an impairment in their recognition for sad and fearful facial expressions and for sad vocal tone. Blair, Colledge, Murray, and Mitchell (2001) presented children with facial expressions of emotion that slowly evolved through 20 successive frames of increasing intensity. They found that children with psychopathic traits needed greater intensity of emotional expression in order to accurately identify sad facial expressions, and they were more likely than children without psychopathic traits to misidentify fearful facial expressions even when at the highest level of intensity of expression. Studies examining the relationship between psychopathy and recognition of facial affect in adults have resulted in conflicting findings. Kosson, Suchy, Mayer, and Libby (2002) examined facial affect recognition in a sample of 77 male inmates and found that psychopathic men were less accurate than non-psychopathic men in identifying facial expressions of disgust. Blair et al. (2004), employing a paradigm similar to Blair et al. (2001), found that psychopathic men evidenced a significant impairment in their ability to identify fearful facial expressions. However, their sample size was quite small (i.e., 19 psychopathic men and 19 controls). Similar deficits in fear recognition were associated with psychopathic personality characteristics in a male college sample (Montagne et al., 2005). Dolan and Fullam (2006) found significantly lower accuracy recognition for sad faces among psychopaths relative to controls. However, most recently, Glass and Newman (2006) examined recognition of facial affect in a sample of 111 male prison inmates and found that psychopathic offenders performed as well as non-psychopathic offenders in identifying facial expressions of emotion. While most studies investigating facial affect recognition and psychopathy have found some deficit(s), the specific type of deficit has varied across studies and samples. A relatively new emotion-based theory of psychopathy is Blair’s (1995) and Blair et al.’s (2001) Violence Inhibition Mechanism, which posits that the emotional deficits associated with psychopathy are the result of empathy dysfunction, which leads to poor moral socialization. According to this model, psychopathic individuals fail to experience the fear and sadness of others as aversive and therefore fail to learn how to avoid acting and behaving in ways that result in others’ sadness and fear. The neurological basis for this deficit is believed to lie within the limbic system and more specifically, the amygdala. Consistent with this notion, Gordon, Baird, and End (2004) found that college students (n = 22) who scored low on the emotional-interpersonal domain of psychopathy evidenced significantly greater activation in the frontal cortex and amygdala during an affect recognition task compared to their high-scoring counterparts who evidenced greater activation in the visual cortex. The authors concluded that individuals scoring low on emotional-interpersonal features of psychopathy utilized areas of the brain typically associated with emotion interpretation and response when engaged in decoding facial expressions of affect, whereas high-scoring participants relied mostly on areas of the brain associated with visual perception. The current study adds to the burgeoning literature on psychopathy and emotion recognition in two respects. First, the study draws on the largest sample of male inmates to date (n = 145). Many studies in the literature have employed samples of less than 50. Second, the current study considered a broader array of facial expressions than most studies. Of special note, this is the first study to consider facial expressions of shame, which is generally regarded as a quintessential “moral emotion” ( Tangney, Stuewig, & Mashek, 2007), and thus is of special relevance to the study of psychopathy. (Guilt was not included because there is no clearly definable facial expression associated with feelings of guilt.) Consistent with the Violence Inhibition Mechanism (VIM) model, we hypothesized that inmates high in psychopathy would evidence impaired recognition of sad and fearful facial expressions. Although not specifically addressed by VIM, the theory implicitly suggests that such difficulties in affect recognition would extend to shame. We also predicted that inmates high in psychopathy would have greater difficulty recognizing less intense facial expressions of emotion. Lastly, we predicted that the interpersonal and affective features of psychopathy (i.e., Part 1) would contribute most to the ability to identify facial expressions of emotion compared to the social deviance/antisocial lifestyle features (i.e., Part 2), as suggested by Gordon et al.’s (2004) study of undergraduates.
