Abstract

The neuropeptide oxytocin improves the performance in facial emotion recognition tests in healthy volunteers and in individuals with schizophrenia. Different paradigms are used in emotion recognition tasks, engaging different neurobiological bases. To date, the effects of oxytocin in facial emotion matching tasks have not been studied. The objective of this study was to evaluate the effects of intranasal oxytocin in a facial emotion matching task in patients with schizophrenia and healthy volunteers. Twenty patients and 20 healthy volunteers received 48 IU intranasal oxytocin and placebo in a double-blind, randomized, placebo-controlled, within subjects design. Fifty minutes after treatment, subjects completed a facial emotion matching task and three control tests. Oxytocin failed to improve facial affect processing, in contrast with previous results. Possible explanations are the fact that we used a facial emotion matching paradigm instead of emotion labeling tasks and a higher dose of oxytocin than the one used in most similar studies.

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.
