Abstract
Newborn heart rate consistently accelerated following an auditory stimulus of moderate intensity. With the long interstimulation interval employed, a brief 2-sec. stimulus elicited a brief acceleration which showed no decrement in 30 repetitions over two days. With a longer 10-sec. stimulus, the acceleration was initally prolonged and this prolonged acceleration diminished after a few repetitions. After a 24-hour interval, the 10-sec. stimulus continued to elicit only a brief acceleration in Ss with prior stimulation experience but elicited a prolonged response in age-controls.
