The present study examined the following two hypotheses: (a) shock which has been associated with food will reduce responding less than shock which has not been associated with food: (b) response-contingent shock will reduce responding more than response-noncontingent shock. Response rates and the number of reinforcements received in Punishment training, and response rates in Punishment-Extinction training were examined for the following five groups: (a) shock and pellet for the same response (Pun-Rft Group): (b) shock and food for different responses (Pun Group): (c) response-noncontingent shock delivered automatically as response-contingent food becomes available for the next response (Shock-SD Group): (d) response-noncontingent shock delivered automatically independent of the availability of reinforcement (NC-Shock Group): (e) no shock (Control Group). The results indicated that (a) response-contingent and response-noncontingent shock reduced responding equally in Punishment training, and that (b) following Punishment-training, response-contingent shock reduced responding in Punishment-Extinction training whereas response-noncontingent shock had no effect on rate of responding in Punishment-Extinction training. The results also indicated that shock which had been associated with food had the same overall effect on response rates as shock which had not been associated with food. The relevance of these results to the discriminative and conditioned reinforcing functions of shock was discussed. / Arts, Faculty of / Psychology, Department of / Graduate

At birth, male and female rats were randomly assigned to either a handled or nonhandled condition. The handled Ss were given tactual stimulation for a five minute period from days five to twenty-five. During the preweaning period Ss in the nonhandled condition were given the least possible amount of experimenter handling. When Ss were between 80 to 100 days old both handled and nonhandled Ss were randomly assigned to one of four acquisition conditions and were trained and tested in a straight alley runway. These conditions were; continuous reinforcement in a large goalbox, continuous reinforcement in a small goalbox, partial reinforcement in a large goalbox, and partial reinforcement in a small box. Each S was then given 60 acquisition trials at the rate of 5 trials per day. Following completion of the acquisition trials all Ss received 50 nonreward trials which were also given in blocks of 5 trials per day. On both acquisition and extinction trials, time measures were taken for startbox and runway performance. For the purpose of analysis all time measures were converted into speed scores. The results showed that all experimental treatments, (i.e. handling, reward schedule and goalbox size), had a significant effect on the rate of experimental extinction. Infantile handling, a partial reinforcement schedule, and a large goalbox were all conducive to decreasing the rate of extinction of a running response. / Arts, Faculty of / Psychology, Department of / Graduate
