Responses to infant-directed singing in infants of mothers with depressive symptoms

This study explored responses to infant-directed (ID) singing in infants of mothers with and without depressive symptoms under two conditions: mother sings to infant, and stranger sings to infant. Sixteen, 3–9-month-old infants of mothers with depression were matched by age and gender to sixteen infants of mothers without depression. Infant gaze responses toward each singer were coded from video and ranged from most negative to most positive, in the order of roaming, averted, neutral, intermittent and sustained. Mothers’ depression status had no effect on infant gaze response toward ID singing from mother or stranger. During ID singing from mother, infants displayed high levels of either neutral or sustained gaze. In response to ID singing from strangers, infants demonstrated sustained gazes more than any other gaze type. Infants also showed significantly more roaming and neutral gaze toward mother than stranger, and used significantly more averted and sustained gaze with stranger than mother. Findings indicate that infants of depressed mothers did not display a depressed interaction style with their mother or with a stranger during ID singing. Additionally, infants in both groups appeared capable of discriminating their mother from a stranger. ID singing appears to enhance face-to-face interaction such that infants can experience self-regulation, even when mothers have depression. Findings support the idea of combining ID singing and interaction coaching as a therapeutic intervention for mothers with depression and their infants.

► Infant gaze responses to infant-directed singing from mother and stranger were not influenced by mothers’ depression.
► Infants of depressed mothers did not demonstrate a depressed interaction style with their mother or with a stranger during ID singing.
► During infant-directed singing, infants could distinguish their mother from stranger, regardless of mother's depression status.
► ID singing appeared to enhance face-to-face interaction such that infants could have meaningful experiences in self-regulation, even when mothers had depression.
