Understanding Emotion Regulation and Humor Styles in Individuals with Callous-Unemotional Traits and Alexithymic Traits

Psychopathy and Impairments in Emotion Regulation: A systematic review and Meta-analysis

Considering the sparse but rapidly growing literature concerning the relationship between psychopathy and emotion regulation, taking stock of accumulating knowledge in a systematic review and meta-analysis of the existing results is needed. We performed a systematic search (up to May 30, 2024) following PRISMA guidelines of five scientific databases (PsycINFO, PsycARTICLES, MEDLINE, PubMed, Scopus and Web of Science). Also, gray literature was searched. After removing the duplicates, a total of 8.786 records were screened, and 73 articles were selected based on the inclusion criteria used for systematic review. The meta-analytic procedure was performed on 55 identified studies consistent with the criteria adopted, which overall comprised 29.856 individuals. The current systematic and meta-analysis review has clarified the association between impairments of emotional regulation abilities and facets of psychopathy. More specifically, analyses indicated that emotional dysregulation is associated with overall levels of psychopathic traits, as well as with both the lifestyle and affective components of psychopathy, which suggests the utility of assessing these features when designing interventions focused on modulating negative emotional states and enhancing regulation of impulsive behaviors.

Aggressive Humor and Social Connectedness: The Moderating Roles of Subjective Social Status and Gender

Aggressive humor has been conceived as a maladaptive humor style that jeopardizes social relationships. However, past studies have yielded inconsistent findings regarding the detrimental effects of aggressive humor on social relationships. This study attempts to advance the existing literature by examining the gender difference in the moderating role of subjective social status in the association between aggressive humor and social connectedness. Participants were 228 (53.1% female) adults aged from 18 to 53 years (M = 23.19, SD = 6.43). The hypothesized moderated moderation effect was significant, suggesting that gender significantly moderated the moderating effect of subjective social status on the association between aggressive humor and social connectedness. Subjective social status significantly moderated the association between aggressive humor and social connectedness for men but not for women. For men, aggressive humor was negatively associated with social connectedness when subjective social status was low or medium, but the association was not significant when subjective social status was high. For women, aggressive humor was not associated with social connectedness regardless of subjective social status. Implications of the findings are discussed.

Difficulties in facial emotion recognition: taking psychopathic and alexithymic traits into account

BACKGROUND

Alexithymic and psychopathic traits are closely associated, but distinct constructs. Both have been associated with facial emotion processing deficits reflecting empathy deficits, however the underlying mechanism contributing to these deficits is not well-understood.

METHODS

This study investigated facial emotion recognition performance in a non-clinical sample (N = 110) including both male and female participants, with varying levels of psychopathic and alexithymic traits. Facial emotion recognition was assessed using a computerized task, that presented different expressions depicting five emotional states (pain, fear, sadness, anger, happiness) and neutral expressions.

RESULTS

Results suggest that the high psychopathic traits group reported lower accuracy compared to the low psychopathic traits group, indicating a more generalized deficit in facial affect recognition, across all emotions. The alexithymic groups (high vs. low) on the other hand did not differ in their performance on the task for any of the emotions presented.

CONCLUSION

These findings add to the current body of research regarding face processing categorization deficits in relation to psychopathic and alexithymic traits and can inform prevention and intervention efforts that aim to facilitate facial emotion recognition in individuals with these personality traits.
