Previous research using a conditioned-attention paradigm demonstrated that 4-month-old infants of depressed mothers (a) failed to acquire associations when a segment of their mothers' infant-directed (ID) speech signaled the presentation of a smiling face but (b) did acquire associations when a segment of an unfamiliar nondepressed mother's ID speech signaled the face (P. S. Kaplan, J. -A. Bachorowski, M. J. Smoski, & W. J. Hudenko, 2002). In the present study, 5- to 13-month-old infants of depressed mothers failed to acquire associations when either their own mothers' (Experiment 1) or an unfamiliar nondepressed mother's (Experiments 1 and 2) ID speech signaled a face. However, these infants acquired associations when a segment of an unfamiliar nondepressed father's ID speech served as the signal (Experiment 2). One possible explanation of these results is that infants of depressed mothers selectively "tune out" ID speech from their mothers and from other, nondepressed, women.
先前使用条件性注意范式的研究表明，抑郁母亲的4个月大婴儿：(a) 当母亲的一段面向婴儿的（ID）言语预示着笑脸出现时，未能建立起关联；但(b) 当一段不熟悉的非抑郁母亲的ID言语预示着笑脸出现时，确实建立起了关联（P. S. 卡普兰、J. -A. 巴霍罗夫斯基、M. J. 斯莫斯基和W. J. 胡登科，2002年）。在本研究中，抑郁母亲的5至13个月大婴儿，当他们自己母亲的（实验1）或不熟悉的非抑郁母亲的（实验1和2）ID言语预示着一张脸出现时，未能建立起关联。然而，当一段不熟悉的非抑郁父亲的ID言语作为信号时，这些婴儿建立起了关联（实验2）。这些结果的一种可能解释是，抑郁母亲的婴儿会选择性地“忽略”来自自己母亲以及其他非抑郁女性的ID言语。
