Habituation of the galvanic skin response to tone as a function of age.

ABSTRACT

Habituation of the galvanic skin response (GSR) to tone in male college students varying in age from 18-39 years old was examined. Older subjects habituated more slowly to tone than did younger ones. This confirmed our past work on habituation of the GSR to electric shock. The GSR is shown to be a sensitive and reliable measure of small differences in age as it affects learning. The clinical usefulness of this quantitative and sensitive measure in detecting small and early changes in learning and memory deficits associated with age and dementia is discussed.
