Oxytocin modulates cooperation within and competition between groups: An integrative review and research agenda

De Dreu, Carsten K.W.·2012·Hormones and Behavior

Abstract

The author reviews evidence that hypothalamic release (or infusion) of the neuropeptide oxytocin modulates the regulation of cooperation and conflict among humans because of three reasons. First, oxytocin enables social categorization of others into in-group versus out-group. Second, oxytocin dampens amygdala activity and enables the development of trust. Third, and finally, oxytocin up-regulates neural circuitries (e.g., inferior frontal gyrus, ventromedial prefrontal cortex, caudate nucleus) involved in empathy and other-concern. Consistent with an evolutionary perspective on the functionality of cooperation, it is concluded that oxytocin-motivated cooperation is mostly parochial-it motivates (i) in-group favoritism, (ii) cooperation towards in-group but not out-group members, and (iii) defense-motivated non-cooperation towards threatening outsiders. Thus, in addition to its well-known role in reproduction and pair-bond formation, oxytocin's primary functions include in-group "tend-and-defend." This review concludes with avenues for new research on oxytocin's functions in within-group cooperation and between-group competition. This article is part of a Special Issue entitled Oxytocin, Vasopressin, and Social Behavior.

  • OXT can promote risk aversion and noncooperation toward individuals perceived as outsiders.

    “since OXT can also promote risk aversion (Declerck et al., 2010) and noncooperation toward individuals perceived as outsiders (De Dreu, 2012).”

  • The anxiolytic effect of oxytocin is proposed to facilitate social cohesion during highly risky situations that might otherwise precipitate defection away from threat.

    “The anxiolytic effect of oxytocin is proposed to facilitate social cohesion during highly risky situations that might otherwise precipitate defection away from threat (4).”
  • Oxytocin triggers a "tend and defend" form of parochial altruism, accentuating cooperative behavior toward the in-group as well as defensive behavior toward out-groups.

    “This suggests that oxytocin triggers a “tend and defend” form of parochial altruism, accentuating cooperative behavior toward the in-group as well as defensive behavior toward out-groups (4).”
  • In some studies oxytocin only increases positive perceptions or social motivations toward others, and in other studies it also amplifies pre-existing social motivations or perceptions, whether positive or negative.

    “Finally, in some studies oxytocin only increases positive perceptions or social motivations toward others (Chang et al., 2012; Shamay-Tsoory et al., 2013) and in other studies it also amplifies pre-existing social motivations or perceptions, whether positive or negative (De Dreu, 2012).”
  • Under certain circumstances, oxytocin may activate a positive feedback system, such that oxytocin may trigger a behavior or motivation, or vice versa, and the behavior or motivation may trigger further oxytocin release.

    “As a final effect of oxytocin, it is thought that under certain circumstances, oxytocin may activate a positive feedback system, such that oxytocin may trigger a behavior or motivation, or vice versa. Then, the behavior or motivation may trigger further oxytocin release, which may again initiate more of the behavior (Uvnäs-Moberg, 1998; De Dreu, 2012).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
