  • Title: Acoustic features and auditory perceptions of the cries of newborns with prenatal and perinatal complications.
    Author: Zeskind PS, Lester BM.
    Journal: Child Dev; 1978 Sep; 49(3):580-9. PubMed ID: 710187.
    Abstract:
    This article describes 2 experiments which examine the relation between neonatal cry features and obstetric histories. Experiment 1 shows that 24 clinically healthy, normal newborns who may be at risk due to a high number of prenatal and perinatal complications can be distinguished from 24 low-complications infants by harmonic and durational features of the cry. High-complications infants required more stimulation to elicit the cry, had a longer latency to cry onset, a shorter first cry expiration, a higher cry pitch, and cried less in total time than low-complications infants. In experiment 2, naive adults rated the high-complications infant cries as more aversive, grating sick, urgent, distressing, piercing, discomforting, and arousing than low-complications infant crues. Factor analyses showed that although the low-complications infant cries were described along one dimension of discomfort, a second factor emerged conveying the "sick" nature of the sound of the cry of the high-complications infants. It was suggested that certain cry features may reflect the risk status of the infant.
