Incremental exposure facilitates adaptation to sensory rearrangement

The rate of adaptation to unusual patterns of vestibular stimulation is enhanced if the final stimulus level is achieved gradually rather than in a single step (6,7). Measurements of adaptation to visual rearrangement elicited by stepwise and single-step exposure indicate that incremental exposure also facilitates adaptation to visual rearrangement; adaptation is diminished when the optical displacement is varied nonsystematically during exposure. Enhancement of adaptation to unusual patterns of sensory stimulation by incremental exposure may reflect a general principle of sensorimotor function.
