Abstract : In a previous experiment, performance on a pursuit rotor task was found to adapt to impulsive acoustic stimulation by the fourth day of exposure. The purpose of the present study was to determine if performance would regain sensitivity to the stimulus after an interval of time. Six subjects who participated in the initial experiment were retested after intervals ranging from five to eight months. After a retraining day, the subjects were presented a retention test day in which the procedure was identical to that used on the four test days of the prior experiment. The stimulus (peak intensity of 112 dB with a 400 millisecond duration) was presented nine times in a semi-random fashion. The results are reported. (Author)
