Abstract

Background In nonhuman mammals, the neuropeptide oxytocin has repeatedly been shown to increase social approach behavior and pair bonding. In particular, central nervous oxytocin reduces behavioral and neuroendocrine responses to social stress and is suggested to mediate the rewarding aspects of attachment in highly social species. However, to date there have been no studies investigating the effects of central oxytocin mechanisms on behavior and physiology in human couple interaction. Methods In a double-blind placebo-controlled design, 47 heterosexual couples (total n = 94) received oxytocin or placebo intranasally before a standard instructed couple conflict discussion in the laboratory. The conflict session was videotaped and coded for verbal and nonverbal interaction behavior (e.g., eye contact, nonverbal positive behavior, and self-disclosure). Salivary cortisol was repeatedly measured during the experiment. Results Oxytocin significantly increased positive communication behavior in relation to negative behavior during the couple conflict discussion (F = 4.18, p = .047) and significantly reduced salivary cortisol levels after the conflict compared with placebo (F = 7.14, p = .011). Conclusions These results are in line with animal studies indicating that central oxytocin facilitates approach and pair bonding behavior. Our findings imply an involvement of oxytocin in couple interaction and close relationships in humans.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Oxytocin is released during contact with a partner and helps maintain long-term romantic relationships.

    “The hypothalamic peptide oxytocin (OXT) is released during partner contact (Grewen, Girdler, Amico, & Light, 2005) and contributes to the maintenance of long-term relationships (Ditzen et al., 2009;Kreuder et al., 2017;Scheele et al., 2013).”
  • Underlying human romantic attachment is a collection of interlocking brain systems hypothesized to have evolved to suit the reproductive needs of our ancestors.

  • Brain chemicals such as oxytocin, dopamine, testosterone, and many others seem to regulate interpersonal drives and emotions, including the formation of romantic pair-bonds.

  • These underlying brain phenomena do much to shape, as well as respond to, higher-level romantic experiences across a wide range of theoretical conceptions.

    “Although love is not simply reducible to these brain chemicals or pathways—and although there are many different theories of love, including how it should be defined—what is clear by now is that these underlying phenomena do much to shape (as well as to respond to) our higher-level romantic experiences, across a wide range of theoretical conceptions.”

    From The Medicalization of Love (2015) · cites this paper as [24]

  • Nasally inhaled oxytocin can reduce stress levels and promote more positive communication between couples engaged in an argument.

    “In one study, Swiss researchers showed that nasally inhaled oxytocin can reduce stress levels and promote more positive communication between couples engaged in an argument (Ditzen et al. 2009).”

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.
