In the present article, we introduce the quadratic vagal activity-prosociality hypothesis, a theoretical framework for understanding the vagus nerve's involvement in prosociality. We argue that vagus nerve activity supports prosocial behavior by regulating physiological systems that enable emotional expression, empathy for others' mental and emotional states, the regulation of one's own distress, and the experience of positive emotions. However, we contend that extremely high levels of vagal…

Moderate Baseline Vagal Tone Predicts Greater Prosociality in Children

Moderate vagal tone at rest in early childhood represents a physiological preparedness or tendency to engage in different forms of prosociality across different contexts that helps prepare children to sympathize, comfort, and share with others.

Affective and physiological responses to the suffering of others: compassion and vagal activity.

It is proposed that compassion is associated with activation in the parasympathetic autonomic nervous system through the vagus nerve, and increases in RSA during compassion positively predicted an established composite of compassion-related words, continuous self-reports of compassion, and nonverbal displays of compassion.

Physiological mechanisms of prosociality.

Social Value Orientation Moderated the Effect of Acute Stress on Individuals’ Prosocial Behaviors

Acute stress is believed to lead to prosocial behaviors via a “tend-and-befriend” pattern of stress response. However, the results of the effect of acute stress on prosocial behavior are

Can we test the influence of prosociality on high frequency heart rate variability? A double-blind sham-controlled approach

Data reveal no evidence toward and effect of the experimental manipulation on high frequency heart rate variability, electromyographical activity of the corrugator supercilii and self-reported measure of social closeness as an index of behavioral prosociality.

Inducing empathy affects cardiovascular reactivity reflected in changes in high-frequency heart rate variability

It is indicated that inducing empathy affects phasic vagal activity implied by parasympathetic mechanisms whereas the association of cardiovascular reactivity and social engagement behaviour needs further investigation.

The sociocultural appraisals, values, and emotions (SAVE) framework of prosociality: core processes from gene to meme.

This work considers how phenomena such as altruistic punishment, prosocial contagion, self-other similarity, and numerous others give rise to prosocial behavior and extends the reasoning to chart the biological underpinnings of prosociality and apply the framework to understand the role of social class in prossociality.

Cardiac vagal tone predicts inhibited attention to fearful faces.

It is demonstrated that individual differences in HRV predict attentional inhibition and suggests that successful inhibition and novelty search may be mediated by cortical inhibitory mechanisms among people with high cardiac vagal tone.

Vagal tone, development, and Gray's motivational theory: Toward an integrated model of autonomic nervous system functioning in psychopathology

In this paper, thevagal tone literature is reviewed, and discrepancies, including the lack of specificity of vagal tone as a psychophysiological marker, are clarified.

A discrete emotions approach to positive emotion disturbance in depression

Two studies compare how depressive symptoms relate to distinct positive emotions at both trait and state levels of assessment and indicate that symptoms of depression were most strongly associated with decreased trait pride and decreased positive emotion experience to pride-eliciting films.

Power, Distress, and Compassion

As predicted, participants with a higher sense of power experienced less distress and less compassion and exhibited greater autonomic emotion regulation when confronted with another participant's suffering.

The social costs of emotional suppression: a prospective study of the transition to college.

Findings were robustly corroborated across weekly experience reports, self-reports, and peer reports and are consistent with a theoretical framework that defines emotion regulation as a dynamic process shaped by both stable person factors and environmental demands.

Social power facilitates the effect of prosocial orientation on empathic accuracy.

In 3 studies with university and adult samples, prosocial orientation was more strongly associated with empathic accuracy when distinct forms of power were high than when power was low, and a mediated relationship between prossocial orientation and career satisfaction was shown through empathy accuracy among employees who occupied high-power positions within an organization.

Resting respiratory sinus arrhythmia is associated with tonic positive emotionality.

It is suggested that resting RSA indexes aspects of a person's tonic positive emotionality, especially at the level of personality traits, long-term moods, the disposition toward optimism, and baseline reports of current emotional states.

Flustered and faithful: embarrassment as a signal of prosociality.

The authors demonstrate that observers recognize the expression of embarrassment as a signal of prosociality and commitment to social relationships, and respond with affiliative behaviors toward the signaler, including greater trust and desire to affiliate with the embarrassed individual.
