Abstract

Although the infant–caregiver attachment bond is critical to survival, little is known about the biological mechanisms supporting attachment representations in humans. Oxytocin plays a key role in attachment bond formation and maintenance in animals and thus could be expected to affect attachment representations in humans. To investigate this possibility, we administered 24 IU intranasal oxytocin to healthy male adults in a double-blind, placebo-controlled, crossover designed study and then assessed memories of childhood maternal care and closeness—two features of the attachment bond. We found that the effects of oxytocin were moderated by the attachment representations people possess, with less anxiously attached individuals remembering their mother as more caring and close after oxytocin (vs. placebo) but more anxiously attached individuals remembering their mother as less caring and close after oxytocin (vs. placebo). These data contrast with the popular notion that oxytocin has broad positive effects on social perception and are more consistent with the animal literature, which emphasizes oxytocin's role in encoding social memories and linking those memories to the reward value of the social stimulus.

  • A study by Unkelbach, Guastella, and Forgas showed that male participants were quicker to identify positively-valenced stimuli associated with bonding and relationships when operating under the influence of oxytocin compared to a placebo.

    “In line with this view, a study by Unkelbach, Guastella, and Forgas [68] showed that male participants were quicker to identify positively-valenced stimuli associated with bonding and relationships when operating under the influence of oxytocin compared to a placebo.”
  • Exogenous OXT can have anxiogenic effects in humans exposed to social stimuli.

    “Likewise, exogenous OXT can have anxiogenic effects in humans exposed to social stimuli (Bartz et al., 2010; Striepens et al., 2012; Grillon et al., 2013; MacDonald et al., 2013).”
  • In humans, exogenously administered oxytocin enhances the encoding of social memory, both of positive and negative events, suggesting that higher oxytocin levels improve memorization of social interactions.

    “Additionally, in humans, exogenously administered oxytocin enhances the encoding of social memory, both of positive [30] and negative [31] events, suggesting that higher oxytocin levels improve memorization of social interactions.”
  • The effects of intranasal oxytocin appear to be influenced by attachment representations: less anxiously attached individuals remembered their mother as more caring and close after oxytocin, but the opposite effect was observed for more anxiously attached individuals.

    “Notably, the effects of OXT IN appear to be influenced by the attachment representations people possess.Less anxiously attached individuals remembered their mother as more caring and close after OXT IN , but the opposite effect was observed for more anxiously attached individuals (53).”
  • Intranasal administration of OT increases the links between social memories and reward in mothers.

    “intranasal administration of OT increases the links between social memories and reward in mothers (41)”

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.
