Abstract

Breastfeeding behaviours can significantly change mothers' physiological and psychological states. The hormone oxytocin may mediate breastfeeding and mothers' emotion recognition. This study examined the effects of endogenous oxytocin fluctuation via breastfeeding on emotion recognition in 51 primiparous mothers. Saliva oxytocin was assessed before and after the manipulation (breastfeeding or holding an infant), and emotion recognition tasks were conducted. Among mothers who breastfed daily, mothers with more increased levels of oxytocin after breastfeeding showed more reduced negative recognition and enhanced positive recognition of adult facial expressions. These oxytocin functions accompanying breastfeeding may support continued nurturing behaviours and also affect the general social cognition of other adults beyond any specific effect on infants.

  • Breastfeeding mothers demonstrate enhanced emotion cue detection.

    “Breastfeeding mothers also demonstrate enhanced emotion cue detection (Krol et al., 2014; Matsunaga et al., 2020).”

    From The evolved nest, oxytocin functioning, and prosocial development (2023) · cites this paper as Matsunaga et al., 2020

    The Discussion reports improved detection of happy adult facial expressions in mothers whose oxytocin rose more after breastfeeding. It also reports reduced accuracy for angry expressions, so the unqualified claim that breastfeeding mothers have enhanced emotion-cue detection overstates the finding.

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.
