本研究探讨了母亲抑郁和依恋安全感对婴儿大脑活动和自主活动的综合影响。记录了抑郁症、阈下抑郁症和非抑郁症母亲的 159 名 13-15 个月大婴儿在基线和两种社会互动条件下的脑电活动、心率和迷走神经张力。在传统的陌生情境中观察到依恋行为。研究发现，抑郁母亲的婴儿在所有情况下都表现出左额脑活动相对于右额脑活动减少。此外，无论母亲的抑郁状况如何，不安全依恋的婴儿都会表现出左额脑活动相对减少。研究还发现，抑郁母亲的婴儿在所有情况下都表现出较高的心率。这些结果表明，母亲抑郁和依恋安全感都与婴儿心理生理反应的改变有关。 (C) 2001 Elsevier Science Inc. 保留所有权利。
The present study examined the combined influences of maternal depression and attachment security on infants' brain activity and autonomic activity. Brain electrical activity, heart rate, and vagal tone were recorded from 159 13-15 month old infants of depressed, subthreshold depressed, and nondepressed mothers during a baseline and two social interaction conditions. Attachment behavior was observed during the traditional Strange Situation. It was found that infants of depressed mothers exhibited reduced left relative to right frontal brain activity during all conditions. Moreover, regardless of mother's depression status, insecurely attached infants exhibited relative reduced left frontal brain activity. Infants of depressed mothers were also found to exhibit higher heart rates across all conditions. These results indicate that both maternal depression and attachment security are associated with alterations in infants' psychophysiological responses. (C) 2001 Elsevier Science Inc.
