Human beings exhibit substantial interpersonal trust-even with strangers. The neuroactive hormone oxytocin facilitates social recognition in animals, and we examine if oxytocin is related to trustworthiness between humans. This paper reports the results of an experiment to test this hypothesis, where trust and trustworthiness are measured using the sequential anonymous "trust game" with monetary payoffs. We find that oxytocin levels are higher in subjects who receive a monetary transfer that…

Oxytocin, Trust, and Trustworthiness: The Moderating Role of Music
Evidence has indicated that the neuroactive hormone oxytocin is essential for prosocial behavior, particularly trust. Exogenous administration of oxytocin has been shown to increase trust in humans.
Oxytocin response in a trust game and habituation of arousal
TLDR
Results suggest that the habituation of autonomic arousal is closely related to oxytocin released during trust-related social interactions, and this relationship was absent in the case of neutral (trust-unrelated) oxytocIn level.
U-Shaped Relation between Plasma Oxytocin Levels and Behavior in the Trust Game
TLDR
It is hypothesized that baseline plasma OT is a biomarker that partially predicts the degree of trust and trustworthiness observed in the trust game, and a significant U-shaped relationship between plasma OT with the level of trust, and marginally with thelevel of trustworthiness is observed.
Oxytocin not only increases trust when money is at stake, but also when confidential information is in the balance
TLDR
Results showed that oxytocin does increase trust, and that its effects extend beyond money, and participants on OT were 44 times more trusting that their privacy would not be violated than participants on placebo.
Oxytocin Increases Generosity in Humans
TLDR
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.
Monetary sacrifice among strangers is mediated by endogenous oxytocin release after physical contact
Humans frequently sacrifice resources to help others—even strangers. The proximate mechanisms inducing such sacrifices are not well understood, and we hypothesized that touch might provoke a
Correction: Lack of Association between Human Plasma Oxytocin and Interpersonal Trust in a Prisoner’s Dilemma Paradigm
TLDR
Previous published work that used oxytocin immunoassays without sample extraction should be reexamined and future research exploring links between endogenous human Oxytocin and trust or social behavior should proceed with careful consideration of methods and appropriate biofluids for analysis.
Oxytocin and the Biological Basis for Interpersonal and Political Trust
Political scientists have documented the many ways in which trust influences attitudes and behaviors that are important for the legitimacy and stability of democratic political systems. They have
Oxytocin and social perception: Oxytocin increases perceived facial trustworthiness and attractiveness
TLDR
It is found that oxytocin administration increased ratings of trustworthiness and attractiveness of male and female targets in raters of both sexes relative to control ratings, suggesting that higher levels of this neuropeptide may enhance affiliative behaviour towards unfamiliar others.
Lack of Association between Human Plasma Oxytocin and Interpersonal Trust in a Prisoner’s Dilemma Paradigm
TLDR
Previous published work that used oxytocin immunoassays without sample extraction should be reexamined and future research exploring links between endogenous human Oxytocin and trust or social behavior should proceed with careful consideration of methods and appropriate biofluids for analysis.

TLDR
Evidence is provided for a hormone that is associated with a negative social interaction, distrust, and positive and negative physiologic controls over social behaviors, as there are for other important behaviors.

Abstract We designed an experiment to study trust and reciprocity in an investment setting. This design controls for alternative explanations of behavior including repeat game reputation effects,
A Neural Basis for Social Cooperation
Cooperation based on reciprocal altruism has evolved in only a small number of species, yet it constitutes the core behavioral principle of human social life. The iterated Prisoner's Dilemma Game has

TLDR
The possibility that the neural circuits that mediate reward evolved for ethologically relevant cues, such as social attachment, is considered, and mesocorticolimbic dopamine appears important for maternal behavior in rats and pair bonding in monogamous voles.
Altruistic punishment in humans
TLDR
It is shown experimentally that the altruistic punishment of defectors is a key motive for the explanation of cooperation, and that future study of the evolution of human cooperation should include a strong focus on explaining altruistic punished.
Detrimental effects of sanctions on human altruism
TLDR
This work shows experimentally that the prevailing self-interest approach has serious shortcomings because it overlooks negative effects of sanctions on human altruism, and challenges proximate and ultimate theories of human cooperation that neglect the distinction between fair and unfair sanctions.

TLDR
The development of transgenic mice with specific deficits in social memory represents a promising approach to examine the cellular and neural systems of social cognition.
