Abstract
The effect on right ear sensitivity of a distracting stimulus presented to the left ear was investigated in 20 male Ss. Two right ear performance change scores were derived‐immediate decrement, and rate of performance recovery with repeated presentations of the distractor. The results indicated that immediate performance decrement was positively related to initial orienting response size to an auditory stimulus, while rate of performance recovery was found to relate to the speed with which the orienting response to an auditory stimulus habituated.
