THE RETENTION OF EFFECTS OF "MASSED" AND "DISTRIBUTED" VESTIBULAR STIMULATION AS INDICATED BY THE DURATION OF THE OCULOGYRAL ILLUSION

Abstract

The influence of the distribution of rotational practice trials was studied in relation to (1) rate of habituation to the rotation and (2) retention of the habituation. After preliminary indoctrination, 20 subjects received 39 separate rotational trials and reported the rotational and postrotational durations of oculogyral illusion, a form of apparent motion observed following stimulation of the semicircular canals. One group received rotational trials massed into a single period, while the other group received trials distributed over 4 daily sessions. The rates of habituation of the 2 groups were not significantly different. Results of the tests of retention, given 7 days after habituation, suggested that the masses series produced greater retention. The habituatory effect of visual stimulation did not generalize to a vestibular stimulus with an opposite directional component.
