Genetic and Common Environmental Influences on Behavioral Inhibition in Infancy and Early Childhood.
Corley, Robin; And Others
This study was designed to assess genetic influence on behavioral inhibition and its varying expression in 92 monozygotic and 86 dizygotic twin pairs. Infant behavior and mother-child interaction were observed and videotaped during structured play sessions at age 14, 20, 24, and 36 months. Analysis of the results suggests that most of the overlap in behavioral inhibition is due to overlap in genetic influences, especially at 24 months. In contrast, there is no evidence that shared twin environment contributed appreciably to overlap in the measures. Twins do not appear to be subject to a strong familial influence that affects their response to all situations where behavioral inhibition might be measured. (MDM)
