Abstract

Infant cues, such as smiling or crying facial expressions, are powerful motivators of human maternal behavior, activating dopamine-associated brain reward circuits. Oxytocin, a neurohormone of attachment, promotes maternal care in animals, although its role in human maternal behavior is unclear. We examined 30 first-time new mothers to test whether differences in attachment, based on the Adult Attachment Interview, were related to brain reward and peripheral oxytocin response to infant cues. On viewing their own infant's smiling and crying faces during functional MRI scanning, mothers with secure attachment showed greater activation of brain reward regions, including the ventral striatum, and the oxytocin-associated hypothalamus/pituitary region. Peripheral oxytocin response to infant contact at 7 months was also significantly higher in secure mothers, and was positively correlated with brain activation in both regions. Insecure/dismissing mothers showed greater insular activation in response to their own infant's sad faces. These results suggest that individual differences in maternal attachment may be linked with development of the dopaminergic and oxytocinergic neuroendocrine systems.

  • The brain-level attachment system is maintained in large part by the neuropeptides oxytocin and vasopressin.

    “Our particular focus will be on the brain-level attachment system [30], maintained (in large part) by the neuropeptides oxytocin and vasopressin [31, 32].”

    From Could intranasal oxytocin be used to enhance relationships? Research imperatives, clinical policy, and ethical considerations (2013) · cites this paper as [31]

    The Introduction (page unavailable) identifies the oxytocinergic system as contributing to the maintenance of maternal behavior, and the Discussion links oxytocin to brain pathways involved in attachment. The paper does not establish the attributed role for vasopressin; it instead names dopaminergic reward processing alongside oxytocin. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Mothers with a secure attachment style showed greater activation in brain reward regions of the ventral striatum and in the oxytocin-associated hypothalamus/pituitary region compared to mothers with an insecure adult attachment style.

    “Mothers with a secure attachment style showed greater activation in brain reward regions of the ventral striatum and in the oxytocin-associated hypothalamus/pituitary region compared to mothers with an insecure adult attachment style.”

    From The evolved nest, oxytocin functioning, and prosocial development (2023) · cites this paper as Strathearn et al. (2009)

    The Abstract reports greater ventral striatum and hypothalamus/pituitary activation in securely attached mothers viewing their infants’ faces. The Discussion specifies that the comparison group was insecure/dismissing mothers and says further research is needed for insecure/preoccupied mothers, so the broader reference to mothers with an insecure attachment style is not fully supported. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Plasma oxytocin was also higher in secure mothers.

    “Plasma oxytocin was also higher in secure mothers.”

    From The evolved nest, oxytocin functioning, and prosocial development (2023) · cites this paper as Strathearn et al. (2009)

    The Results section (Oxytocin response to mother-infant interaction, page unavailable) reports significantly higher oxytocin levels in securely attached mothers after five minutes of interaction with their infants, but no difference at baseline. The Methods section (Study design, page unavailable) describes the blood measurement as serum oxytocin, not plasma oxytocin. The claim omits the interaction condition and specifies a different sample type. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Oxytocin plays a role in both relaxation and secure attachment physiology and is associated with greater pro-social behaviors.

    “Oxytocin plays a role in both relaxation and secure attachment physiology and is also associated with greater pro-social behaviors (e.g., improved face expression recognition, enhanced encoding of positive social memories; Isgett, Algoe, Boulton, Way, & Fredrickson, 2016; Mascaro et al, 2015; Strathearn, Fonagy, Amico, & Montague, 2009).”

    From A Systematic Review and Meta-analysis of the Effects of Meditation on Empathy, Compassion, and Prosocial Behaviors (2018) · cites this paper as Strathearn, Fonagy, Amico, & Montague, 2009

    The Discussion (page unavailable) reports higher oxytocin levels in securely attached mothers after interacting with their infants and suggests a role in attachment and social behavior. The Introduction (page unavailable) describes improved facial-expression recognition, social memory, and trust in trials of intranasal oxytocin. Our copy does not establish a role for oxytocin in relaxation. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Differences in adult attachment styles have been associated with modulation of endogenous oxytocin levels.

    “Differences in adult attachment styles have been associated with modulation of endogenous oxytocin levels.”

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.
