Latency of Crying Cessation: Measuring Infants' Discrimination of Mothers' Voices.
Hulsebus, Robert C.
This study investigated at the age at which infants become able to discriminate between their mothers and females strangers, as measured by differential patterns of pauses during the infants' crying while being spoken to by their mothers and female strangers. The subjects, 14 infants ranging in age from 7 to 20 days, were fed, burped, and changed, then left in their cribs. After continuous crying had developed for at least 30 seconds, the mother and the female stranger, standing out of sight, spoke to the infant for one minute each. Results indicated that 11 of the 14 infants discriminated by voice alone between their mothers and a female stranger. The infants stopped crying significantly sooner and paused significantly longer when their mothers were speaking to them. It is concluded that one- and two-week-old infants are capable of discriminating between the voices of their mother and strangers. (Author/BRT)
