In humans, plasma oxytocin levels were raised following a combination of 15 min of massage followed by a monetary trust game, but not following either massage or trust game alone.
“Morhenn et al. (2008) showed that in both men and women, plasma oxytocin levels were raised following a combination of 15 min of massage followed by a monetary trust game. Plasma oxytocin levels, however, were not raised following either a massage or trust game alone.”
From Endogenous peripheral oxytocin measures can give insight into the dynamics of social relationships: a review (2014) · cites this paper as Morhenn et al., 2008
These results demonstrating oxytocin-induced pupil dilation during the viewing of others' faces point to mechanisms by which oxytocin facilitates human affiliation.
“These results demonstrating oxytocin-induced pupil dilation during the viewing of others' faces nevertheless point to mechanisms by which oxytocin facilitates human affiliation, since oxytocin is thought to be released in situations of trust and warm touch (Morhenn et al., 2008).”

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.
