| Abstract: | Nonnutritive sucking response change to auditory stimulation was studied in 1-, 2-, and 3-month-old infants. Each of 22 Ss was stimulated with five stimuli, presented four times during three sessions at 24-hour intervals. The 1- and 2-month-old Ss were tested again 1 month later for another three sessions. The response of younger infants was ambiguous. The response of older infants showed reliable shortening of sucking burst and lengthening of sucking interval. Neither differential effects of the stimuli nor habituation of response were found. |
