GENERALIZATION OF HABITUATION OF GSR TO WHITE NOISE OF VARYING INTENSITIES

Two groups, each consisting of 40 university students, were given eight habituation trials of a 2-sec white noise at a mean inter trial interval of 1 min. One group received a 67-dB stimulus, the other a 76-dB stimulus. On Trials 9–12, 20 Ss from each group were tested for stimulus generalization at intensities of 70 or 73 dB. Mean GSR on the first test trial was the measure of stimulus generalization. A reliable upward-sloping generalization gradient to increases in stimulus intensities and a trend for a downward-sloping gradient to decreases in intensities were found. © 1969, Psychonomic Journals, Inc..
