Two-week-old full-term newborns (26 born to depressed mothers and 26 born to non-depressed mothers) were videotaped for three 2-min intervals during: (1) a baseline silent period, (2) the playing of a musical lullaby and, (3) the lullaby with vocals added. More maternal depression symptoms were associated with more obstetric complications and newborns spending less time awake during the two music intervals. When the lullaby was played, infants born to mothers with more obstetric complications cried more and made more facial expressions. Infants who made more facial expressions at baseline spent more time awake during the musical lullaby with vocals but showed more distress, whereas fewer facial expressions indicated greater attention. Greater birthweight was related to sleeping longer during baseline, but spending more time awake and making fewer facial expressions during the musical lullaby without voice. The findings are discussed in terms of potential factors that may relate to infant music preferences in the very early weeks of human development.
两周大的足月新生儿（26 名来自抑郁母亲，26 名来自非抑郁母亲）在三个 2 分钟的时间段内被录像：（1）基线安静期，（2）播放摇篮曲，以及（3）加入人声的摇篮曲。母亲的抑郁症状越多，新生儿在两段音乐期间的清醒时间就越少。当播放摇篮曲时，来自有更多产科并发症母亲的婴儿哭得更多，做出更多面部表情。在基线时做出更多面部表情的婴儿在带有人声的摇篮曲中会花更多时间保持清醒，但表现出更多的痛苦，而较少的面部表情则表示更多的注意力。更大的出生体重与在基线期间睡眠时间更长有关，但在没有声音的摇篮曲期间，清醒时间更长，面部表情更少。这些发现是根据可能与人类发展早期婴儿对音乐偏好有关的潜在因素进行讨论的。
