Abstract

A comparison of behavior of infant monkeys shortly after birth reveals differences in reactivity which can be related to the route of delivery, whether vaginal or cesarean section. The depression of behavior in the surgically delivered infants persists through day 5 postpartum and ultimately appears as lowered conditionability. Anesthetics or other drugs are not causal factors.
