An aftereffect in judgment of auditory duration

Two experiments were designed to investigate the occurrence of atemporal aftereffect following auditory spatial stimulation. The task required Ss to compare by means of a motorresponse the duration of a test tone presented at a variable interval after stimulation with a standard tone. In both experiments the posttest duration was underestimated relative to the pretest duration, i.e., there was a temporal aftereffect(TAE). A control experiment which involved Ss making estimates of the duration of the test tones, without the presentation of interpolated standard tones, did not show this effect. The temporal aftereffect followed a function analogous to the “distance paradox” forspatial aftereffects.
