Demonstrates some of the research results obtained from the application of the Cambridge Behavioral and Neurological Assessment Scales to normal newborns in hospital nurseries. Indicates that there are standard differences in temperament or behavior among babies from different ethnic backgrounds -- Caucasian, Navajo, Aborigine, African -- and that such differences among humans are biological as well as cultural. Tests include the Moro startle response, the newborn's wailing response, and the infant's ability to control its head and neck muscles. Produced by Daniel G. Freedman.
