The comparability of latency, duration and amplitude scores of the first derivative of the galvanic skin response (GSR) in normal and retarded young adults was studied under various conditions of stimulus intensity, duration, and repetition. Duration scores were a measure of the onset‐to‐peak time of the primary wave and were found to be most sensitive to changes in stimulus conditions, least subject to measurement errors, and least cumbersome to handle statistically. Latency scores were found to be least sensitive, with amplitude scores occupying an intermediate position. The correlations between the three types of responses were low and showed no substantial or meaningful differences between stimulus conditions and subject groups. The authors concluded that for some types of GSR measurement, duration scores can replace the more commonly used amplitude scores.
