"Two groups of Ss were conditioned to respond to a tone by making extensor movements of the finger. The hand was then turned over so that a flexor movement would be required to remove the finger from the electrode. Both groups were then tested to the conditioned stimulus alone. For the control groups of 27 Ss the same tone was used, and for the experimental group of 32 Ss a different tone was used. Twenty-five Ss in the control, and 22 Ss in the experimental group gave conditioned responses in the new situation. All Ss of the experimental group gave generalized responses (made flexor movements). In the control group, four of the 25 responding Ss gave specific (extensor) responses in this situation. Thus, the results suggest some trend for response generalization, or the tendency for an act rather than a movement to become attached to a stimulus, to be a function of stimulus generalization."
