Two experiments were conducted to determine how soon after birth infants are able to distinguish their fathers voice from that of a male stranger. The dependent variable was latency of crying cessation following initiation of adult speech. In the initial experiment, 21 infants with an average age of three days were tested and in the second experiment, 22 seven day olds were the subjects there was equivalent representation of six in each subject group. Comparisons were conducted in a single session for each infant. Results indicated that while there was a clear effect of the fathers voice with the younger subjects, statistically significant effectiveness was only documented with the seven day old infants. Within one week of birth infants are capable of discriminating their fathers voice from voices of other males.
