Physiological responses associated with time estimation in a human operant situation
Tóm tắt
GSR, heart rate, forearm muscle potential, and volume pulse of the finger were recorded for five human Ss during six sessions in which positive reinforcement was obtained by maintenance of an interval of slightly more than one minute between lever presses (differential reinforcement of low rate, with limited hold). Systematic changes of physiological activity occurred in association with the lever-pressing response, whether reinforced or non-reinforced. These changes were most pronounced for the GSR, where two different patterns of activity were exhibited by the Ss, and for forearm muscle potential, where all Ss showed their largest increment of tension following the lever press. The consistent GSR to reinforcement which had been observed in previous studies involving variable-interval and fixed-ratio reinforcement did not occur in the present study. Among the five Ss, one showed significant increments of both GSR and heart rate to reinforcement, a second showed a significant increment of heart rate, and a third showed a significant increment of the volume pulse response.
