Imagining the baby: Neural reactivity to infant distress and mind-mindedness in expectant parents.

Neural and psychological processes in pregnancy may be important antecedents for caregiving postpartum. Employing event-related potentials, we examined neural reactivity to infant emotional faces during the third trimester of pregnancy in expectant mothers (n = 38) and expectant fathers (n = 30). Specifically, expectant parents viewed infant distress and infant neutral faces while electroencephalography was simultaneously recorded. As a psychological measure, we assessed prenatal mind-mindedness towards the unborn child and examined whether neural processing of infant cues was associated with levels of mind-mindedness. Expectant fathers evidenced greater P300 reactivity to infant distress, relative to neutral, faces than expectant mothers. Furthermore, P300 reactivity to infant distress, relative to infant neutral, faces was associated with levels of prenatal mind-mindedness in expectant fathers but not expectant mothers. These findings indicate significant sex differences in the prenatal neural processing of infant cues and relations between neural reactivity to infant distress and the emergence of parental mind-mindedness.
