Abstract
The purpose of this study was to match intensities of stimuli of different sense modalities on the basis of the magnitude of GSR. Twenty-five college students received repeated presentations of each of 6 different intensities of a 1,000 cps tone (43, 48, 53, 58, 63, and 68 db re:.0002 dynes/cm2, in 42 dB of background noise) alternating with a ¼ in. square patch of white light of 0.36 ft.-c. Average GSR magnitude was determined, for each of these stimuli. A graph of the relationship between tone intensity and magnitude of GSR was plotted separately for each S and a tone intensity equivalent to the light was determined by interpolating the average magnitude of response to the light in this graph.
