Parent-infant interaction is known to be influenced bidirectionally by parent and infant characteristics. However, it is unclear whether infant temperament affects parents' neural responses to infant stimuli. 85 infants (6-12 months) were filmed in distress-eliciting tasks, which were coded for infants' negative affect. Mothers' reported infant affect was obtained from the Infant Behavior Questionnaire Very Short Form-Revised. Mothers' EEG activity was recorded while passively viewing photos of own, familiarized, and unfamiliar infants. Multiple regression indicated that mothers who reported greater infant negative affect showed a smaller difference in the late positive potential (LPP) response to own infant versus familiarized infant, controlling for researcher-coded infant negative affect. The findings suggest that parents' perceptions of their infant's temperament, but not independent measures of infant temperament, are related to electrocortical indices of emotional attention.
