Abstract
Conditioned galvanic skin responses were formed to vibro-tactile stimuli in 2 groups of subjects. The generalization gradient of 15 subjects for whom the tactile stimulators were placed at equal intervals along the back from shoulder to waist may have been slightly steeper than the corresponding gradient for 16 subjects for whom the stimulators were placed at equal intervals along the dorsum of the hand, from the tip of the index finger to the wrist. Since on the basis of data on cortical representation a steeper gradient for the hand is necessary to support Pavlov''s'' cortical irradiation hypothesis, the data indicate that this hypothesis is invalid.
