Overhabituation and spontaneous recovery of the galvanic skin response.

Abstract
Examined the time course of recovery from 2 levels of habituation in a 2 * 4 randomized factorial design with 24 psychology students per cell. The criteria of habituation were 2 or 5 successive trials without a response, and the recovery intervals were 1, 2, 4, or 6 min. Recovery of the orienting response was an increasing negatively accelerated function of the recovery interval. The 2 criteria of habituation did not produce significantly different curves of recovery. When both criterion groups were combined at each recovery interval, the median percentages of recovery for the 1-, 2-, 4-, and 6-min intervals were 17, 55, 81, and 84%, respectively.
