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.
众所周知，亲子互动受到父母和婴儿特征的双向影响。然而，目前尚不清楚婴儿气质是否会影响父母对婴儿刺激的神经反应。研究人员让85名6至12个月大的婴儿参与诱发痛苦的任务，并对婴儿的负面情绪进行编码。母亲对婴儿情绪的报告则来自《婴儿行为问卷简版修订版》。在母亲被动观看自己孩子、熟悉婴儿和陌生婴儿的照片时，记录她们的脑电图活动。多元回归分析表明，在控制了研究人员编码的婴儿负面情绪后，报告婴儿负面情绪较强的母亲，在观看自己孩子与熟悉婴儿照片时，其晚期正电位（LPP）反应的差异较小。研究结果表明，与情绪注意力的皮层电活动指标相关的是父母对婴儿气质的感知，而非婴儿气质的独立测量指标。
