On the importance of fundamental frequency and other acoustic features in cry perception and infant development.
This study examined acoustic correlates of adults' ratings of infants' cries. Parents and nonparents rated 12 spontaneous cries from young infants on 8 items describing the cries' aversiveness and on 9 semantic differential items. The results indicated that the duration, the amount of dysphonation, and proportion of energy in various frequency bands were highly correlated with adults' ratings. Further, the pattern of correlations between each of the 17 rating scale items and the acoustic attributes was virtually the same, suggesting that the items represented a single underlying dimension of perceived aversiveness. Finally, no differences were found between the results for parents and nonparents. General issues in the study of cry perception are discussed.
