Infants of mothers who varied in symptoms of depression were tested at 4 and 12 months of age for their ability to associate a segment of an unfamiliar non-depressed mother's infant-directed speech (IDS) with a face. At 4 months, all infants learned the voice-face association. At 12 months, despite the fact that none of the mothers were still clinically depressed, infants of mothers with chronically elevated self-reported depressive symptoms, and infants of mothers with elevated self-reported depressive symptoms at 4 months but not 12 months, on average did not learn the association. For infants of mothers diagnosed with depression in remission, learning at 12 months was negatively correlated with the postpartum duration of the mother's depressive episode. At neither age did extent of pitch modulation in the IDS segments correlate with infant learning. However, learning scores at 12 months correlated significantly with concurrent maternal reports of infant receptive language development. The roles of the duration and timing of maternal depressive symptoms are discussed.
将母亲的抑郁症状不同的婴儿在 4 个月和 12 个月大时进行测试，以评估他们将一段陌生的非抑郁母亲的婴儿指向性言语（IDS）与面孔联系起来的能力。在 4 个月时，所有婴儿都学会了将声音与面孔联系起来。在 12 个月时，尽管没有一位母亲仍处于临床抑郁状态，但具有慢性高自我报告抑郁症状的母亲的婴儿，以及在 4 个月时但不在 12 个月时具有高自我报告抑郁症状的母亲的婴儿，平均而言，并未学会这种关联。对于被诊断为缓解期抑郁症的母亲的婴儿，12 个月时的学习与母亲抑郁发作的产后持续时间呈负相关。在这两个年龄段，IDS 片段中的音高调制程度均与婴儿的学习无关。但是，12 个月时的学习得分与母亲对婴儿接受性语言发展的同期报告显著相关。讨论了母亲抑郁症状的持续时间和时间的作用。
