People often conform to others with whom they associate. Surprisingly, however, little is known about the possible hormonal mechanisms that may underlie in-group conformity. Here, we examined whether conformity toward one’s in-group is altered by oxytocin, a neuropeptide often implicated in social behavior. After administration of either oxytocin or a placebo, participants were asked to provide attractiveness ratings of unfamiliar visual stimuli. While viewing each stimulus, participants were…

Oxytocin enhances implicit social conformity to both in-group and out-group opinions

Oxytocin Facilitates Social Learning by Promoting Conformity to Trusted Individuals

It is proposed that a key role for oxytocin is not in facilitating social trust per se but in conforming to, and learning from, trusted individuals who are either in-group members and/or perceived experts.

Effects of Oxytocin on Social Comparisons in Intergroup Situations

It is demonstrated that OXT facilitates intergroup social comparisons with out-group versus in-group members and, if so, how this modulation manifests is examined.

The Social Salience Hypothesis of Oxytocin

Sex- and Context-dependent Effects of Oxytocin on Social Reward Processing

It is demonstrated that OXT facilitates the impact of sharing positive experiences with others in women, but not men, and that this is associated with differential effects on the amygdala and insula and their functional connections.

Oxytocin and Social Cognition.

Oxytocin is an important modulator of social cognitive processes, although substantially more research is needed in order to understand the complexity of oxytocinergic effects on social perception, cognition, and interpersonal behavior.

Oxytocin Increases Generosity in Humans

Oxytocin and altruism together predicted almost half the interpersonal variation in generosity, indicating that generosity is associated with both altruism as well as an emotional identification with another person.

Social effects of oxytocin in humans: context and person matter

Oxytocin promotes human ethnocentrism

Findings call into question the view of oxytocin as an indiscriminate “love drug” or “cuddle chemical” and suggest that Oxytocin has a role in the emergence of intergroup conflict and violence.

Oxytocin increases trust in humans

It is shown that intranasal administration of oxytocin, a neuropeptide that plays a key role in social attachment and affiliation in non-human mammals, causes a substantial increase in trust among humans, thereby greatly increasing the benefits from social interactions.

The Role of Oxytocin in Human Affect

A third possible alternative explanation for the impact of oxytocin on negative social emotions is proposed and evidence is reviewed to support the social-approach/withdrawal hypothesis and provide directions for future studies.

Group Size and Conformity

This paper reviews theory and research on the relationship between group size and conformity and presents a meta-analysis of 125 Asch-type conformity studies. It questions the assumption of a single
