Relations Between Women's Depressive Symptoms and Perceptions of Infant Distress Signals Varying in Pitch.

Fifteen nondepressed, 15 moderately depressed, and 15 severely depressed women rated tape-recordings of a newborn infant's hunger cry digitally altered to increase in fundamental frequency in 100 Hz increments. Cries were rated on 4 perceptual (e.g., arousing-not arousing) and 6 caregiving rating scale items (e.g., cuddle, feed) used in previous studies (Zeskind, 1983). Analyses of variance showed that, as cry pitch increased, cries were rated as more arousing, aversive, urgent, and sick sounding. Highest pitched cries received highest levels of caregiving interventions. Severely depressed women rated cries as less perceptually salient and less likely to elicit active caregiving responses. Interaction effects showed that severely depressed women were least responsive to highest pitched cries. These results suggest that women's depression may alter perceptions of infant distress signals, especially at times of greater infant distress. 2001 International Society on Infant Studies.
