The purpose of this study was to explore the relationship between mothers' depressive symptoms and the acoustic parameters of infant-directed (ID) singing. Participants included 80 mothers and their 3- to 9-month-old infants. A digital recording was made of each mother's voice while singing to her infant. Extraction and analyses of vocal data revealed a main effect of tempo, meaning that as mothers reported more depressive symptoms, they tended to sing faster to their infants. Additionally, an interaction effect indicated that mothers with depressive symptoms were more likely to sing with tonal key clarity to their male infants. These findings suggest that as mothers experience depressive symptoms, their ID singing may lack the sensitivity and emotional expression that infants need for affect regulation. An intervention that combines interaction coaching and ID singing may help mothers with depressive symptoms to engage in sensitive and emotionally synchronized interactions with their infants.
本研究旨在探讨母亲抑郁症状与婴儿指向性（ID）歌唱的声学参数之间的关系。参与者包括 80 位母亲及其 3 至 9 个月大的婴儿。每位母亲在为婴儿唱歌时，其声音都被录制下来。对声音数据的提取和分析显示出节奏的主要影响，即母亲报告的抑郁症状越多，她们往往会更快地为婴儿唱歌。此外，还存在一个交互效应，表明有抑郁症状的母亲更有可能用清晰的音调为男婴唱歌。这些发现表明，当母亲经历抑郁症状时，她们的 ID 歌唱可能缺乏婴儿调节情绪所需要的敏感性和情感表达。将互动指导和 ID 歌唱相结合的干预措施可能有助于有抑郁症状的母亲与婴儿进行敏感且情感同步的互动。
