Infant behavior and development in relation to fetal movement and habituation.
Fetal movement and habituation were examined in relation to behavior and development in early infancy. 39 fetuses were evaluated between 28 and 37 weeks gestation. A vibrating stimulus was repeatedly applied to the maternal abdomen until the fetus habituated (i.e., ceased moving in response). Fetal movements were observed on an ultrasound monitor by 2 observers who recorded their observations onto a strip chart. Using a median split, fetuses were placed into high- or low-movement groups and fast- or slow-habituating groups. The groups were compared after birth on the Brazelton Neonatal Behavior Assessment Scale and the Bayley Scales of Infant Development. Preliminary evidence is presented that fetal rate of habituation predicts some aspects of infant behavior and development.
