Oxytocin enhances the encoding of positive social memories in humans.

Guastella, Adam J., Mitchell, Philip B., Mathews, Frosso·2008·Biological Psychiatry

Abstract

Background In nonhuman mammals, oxytocin has a critical role in social recognition and the development of long-term bonds. There has been limited research evaluating effects of oxytocin on the encoding and recognition of faces in humans.Methods In a double-blind, randomized, placebo-controlled, between-subject design, we administered oxytocin (24 IU) or a placebo to 69 healthy human male volunteers and then presented 36 happy, angry, or neutral human faces. Participants returned the following day to make "remember," "know," or "new" judgments for a mix of 72 new and previously seen faces.Results Oxytocin-administered participants were more likely to make remember and know judgments for previously seen happy faces compared with angry and neutral human faces. In contrast, oxytocin did not influence judgments for faces that had not been presented previously.Conclusions This study shows that the administration of oxytocin to male humans enhances the encoding of positive social information to make it more memorable. Results suggest that oxytocin could enhance social approach, intimacy, and bonding in male humans by strengthening encoding to make the recall of positive social information more likely.

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.
