Initial evidence for a relation between behaviorally assessed empathic accuracy and affect sharing for people and music.

Are people who are better able to understand or feel the emotions of others also better at understanding or feeling emotions conveyed through music? Although evolutionary theories have proposed that both empathy and music help to foster social connection, few studies to date have examined the relation between behavioral assessments of empathic processes for people and music. We examined this question using 2 independent samples: a laboratory sample of undergraduates (n = 236) and a larger online direct replication with participants across the United States (n = 596). Across both samples, linear mixed effects models showed positive associations between empathic accuracy and affect sharing for people telling personal stories and for musical expression, and results were maintained when including relevant individual differences as covariates. These findings provide initial evidence of a relation between behaviorally assessed empathic processes across social and musical domains. Future research is needed to build upon this evidence by investigating whether active, socially engaged music listening may have a beneficial effect on social cognition.

Oxytocin reactivity to a lab-based stressor predicts support seeking after stress in daily life: Implications for the Tend-and-Befriend theory.

Social relationships play an important role in mental and physical health, particularly during times of stress. However, little is known about the biological mechanisms underlying the tendency to seek support following stress. The Tend-and-Befriend theory suggests that oxytocin (OT) may enhance the desire for social contact in response to stress. Yet, no studies in humans have provided empirical support for the connection between stress-induced changes in endogenous OT and increased support seeking after stress. In the present study, 94 participants performed a standardized laboratory stressor and then completed two weeks of daily assessments of support seeking after stress. In line with preregistered hypotheses, stress-induced plasma OT reactivity to the laboratory stressor was associated with more frequent support seeking behaviors following stress in daily life (i.e., outside of the laboratory). Additional results suggested that attachment anxiety (but not avoidance) strengthened this association. Our findings implicate the OT system in affiliative behaviors following stress, providing empirical support for the Tend-and-Befriend theory.

Revisiting the association between self-reported empathy and behavioral assessments of social cognition.

Previous research has shown a weak association between self-reported empathy and performance on behavioral assessments of social cognition. However, previous studies have often overlooked important distinctions within these multifaceted constructs (e.g., differences among the subcomponents of self-reported empathy, distinctions in tasks assessing lower- vs. high-level social cognition, and potential covariates that represent competing predictors). Using data from three separate studies (total N = 2,376), we tested whether the tendency to take the perspective of others (i.e., perspective-taking), and the tendency to catch the emotions of others (i.e., emotional contagion for positive and negative emotions), were associated with performance on tasks assessing lower- to higher-level social-cognitive ability (i.e., emotion recognition, theory of mind, and empathic accuracy) and affect sharing. Results showed little evidence of an association between any of the self-reported empathy measures and either social-cognitive ability or affect sharing. Using several large samples, our findings add additional evidence to previous work showing that self-report measures of empathy are not valid proxies of behaviorally assessed social cognition. Moreover, we find that the ease with which individuals recognize and understand their own emotions (i.e., alexithymia) is more related to social-cognitive abilities and affect sharing, than their tendency to take the perspective of others, or to vicariously experience the emotions of others.

Social anxiety is associated with greater peripheral oxytocin reactivity to psychosocial stress.

To date, it has been difficult to establish reliable biomarkers associated with specific forms of psychopathology. Social anxiety, for example, is associated with inconsistent biological responses to psychosocial stress on markers including cortisol and salivary alpha-amylase. Thus, it is critical that studies identify more reliable biomarkers that index patterns associated with social anxiety. Two potential candidates are the neuropeptides oxytocin and vasopressin, which have been implicated in stress responsivity across species. Studies have demonstrated a reliable increase in oxytocin, and a surrogate marker for vasopressin, following engagement in the most widely used lab-based psychosocial stress paradigm: the Trier Social Stress Test (TSST). However, no study has examined whether social anxiety moderates peripheral oxytocin or vasopressin reactivity to psychosocial stress. In 101 young adult participants, dimensionally assessed social anxiety was associated with greater plasma oxytocin, but not vasopressin, reactivity to the TSST. Results were maintained following the inclusion of depression as a covariate. Findings suggest that studying changes in peripheral oxytocin concentrations may be a method of differentiating individuals with higher levels of social anxiety.

Stressed connections: cortisol levels following acute psychosocial stress disrupt affiliative mimicry in humans.

Mimicry, and especially spontaneous facial mimicry, is a rudimentary element of social-emotional experience that is well-conserved across numerous species. Although such mimicry is thought to be a relatively automatic process, research indicates that contextual factors can influence mimicry, especially in humans. Here, we extend this work by investigating the effect of acute psychosocial stress on spontaneous facial mimicry. Participants performed a spontaneous facial mimicry task with facial electromyography (fEMG) at baseline and approximately one month later, following an acute psychosocial stressor (Trier Social Stress Test). Results show that the magnitude of the endocrine stress response reduced zygomaticus major reactivity, and specifically spontaneous facial mimicry for positive social stimuli (i.e. smiles). Individuals with higher levels of the stress hormone cortisol showed a more blunted fEMG response to smiles, but not to frowns. Conversely, stress had no effect on corrugator supercilii activation (i.e. frowning to frowns). These findings highlight the importance of the biological stress response system in this basic element of social-emotional experience.

Maternal oxytocin predicts relationship survival during the perinatal transition period: Preliminary evidence.

It is well-known that the neuropeptide oxytocin plays a critical role regulating the formation of adult-adult pairbonds in non-human animals, and recent work suggests oxytocin may similarly play an important role in romantic bonding in humans. Specifically, endogenous oxytocin is predictive of a host of relationship-enhancing behaviors, relationship quality, and even relationship survival amongst newly dating couples. This work suggests that oxytocin can buffer romantic relationships, possibly during especially difficult transition periods. One challenge that many couples face is the birth of a child: a joyous event, but one that is recognized as a major life stressor nonetheless. We aimed to investigate whether maternal oxytocin buffers the parent-partner relationship during the perinatal transition period. To test this, we analyzed data from a longitudinal study of child-bearing women (N = 269) in which endogenous oxytocin was measured in blood plasma during the 1st and 3rd trimesters and at 7-9 weeks postpartum; relationship status was assessed at the outset and 2.5 years postpartum. As predicted, lower maternal oxytocin was associated with greater risk for relationship dissolution by the time the child was a toddler (p < .05). These findings directly replicate research showing that endogenous oxytocin predicts relationship survival in dating couples, but in a novel interpersonal context. That said, only a very small number (N = 7) of couples separated; this, of course, is unsurprising given that the perinatal transition period is not a time when couples typically choose to terminate their relationship. Nonetheless, these findings must be considered preliminary until replicated in future research.
