Are you laughing with me or at me? Psychopathic traits and the ability to distinguish between affiliation and dominance laughter cues.

OBJECTIVE: Laughter conveys important information that supports social communication and bonding. Research suggests that unique acoustic properties distinguish laughter that promotes affiliation from laughter that conveys dominance, but little is known about potential individual differences in laughter interpretation or contagion based on these specified social functions of laughter. Psychopathy is associated with both affiliative deficits (e.g., lack of empathy and impaired social bonding) and behaviors that assert social dominance (e.g., manipulativeness). Thus, relationships between psychopathic traits and impaired laughter interpretation or contagion could give insight into etiological pathways to psychopathy. METHOD: In two studies conducted with four independent samples (total N = 770), participants categorized laughter clips that varied in the degree of affiliation or dominance conveyed. RESULTS: Participants overall drew rich and accurate social inferences from dominant and affiliative laughter and modulated their interest in joining in with laughter based on the type and degree of affiliation and dominance conveyed. However, individuals higher in psychopathic traits failed to distinguish between laughter types and did not modulate their level of engagement based on laughter features. CONCLUSIONS: The results suggest a potential mechanism that underlies the broader social difficulties associated with psychopathic traits.

Children's knowledge and feelings align in response to emotional music.

Examining emotion recognition and response to music can isolate recognition of and resonance with emotion from the confounding effects of other social cues (e.g., faces). In a within-sample design, participants aged 5-6 years in the eastern region of the United States (N = 135, Mage = 5.98, SDage = .54; 78 female, 56 male; eight Asian, 43 Black, 62 White, 13 biracial, and nine "other") listened to clips of calm, scary, and sad music. In separate sessions, participants identified the emotional content of the music or reported on the feelings elicited by the music clip, with above-chance accuracy. Emotion recognition was associated with age and higher levels of child emotional verbal expressivity. Children with higher parent-reported empathy reported greater resonance with the emotion conveyed by music, specifically for sad music. Recognition and resonance were correlated (i.e., alignment), although the relationship varied as a function of the emotion expressed, with the greatest alignment for sad music. Results provide insights into emotion recognition and resonance in the absence of direct social signals and provide evidence that children's ability to recognize and resonate with emotion differs depending on characteristics of the music and the child.
