The introduction of a warning signal preceding shocks greatly increased the effectiveness of avoidance responding. Periods of “warm-up” at the beginning of the session were eliminated, and the number of shocks received by the subjects was greatly reduced. With response-shock interval constant, response rate increased as the interval between the response and the onset of the warning signal was shortened. The response tended to occur shortly after the onset of the warning signal regardless of the duration of these “safe” periods. A greatly elevated response rate was maintained even when the duration of the safe period was reduced to 0.3 sec. Thus, the pre-shock signal obtained nearly exclusive control of the responding and overrode the usual “temporal discrimination” of the response-shock interval. 相似文献

Attack behavior was elicited from squirrel monkeys by externally applied electric shock. The shock elicited attack toward other monkeys, rats, and mice, as well as toward inanimate objects, such as a stuffed doll, and even a round ball. A method of quantifying the attack behavior was devised on the basis of the attack against inanimate objects. This method revealed that the duration and probability of attack was a direct function of the shock intensity. 相似文献

The present study reinforced the two instructors of two students with profound mental retardation first for the instructors' training behaviors, then for improved student learning in a multiple baseline across responses design. Reinforcement of the instructors' training behaviors increased their training behaviors, replicating the findings of previous studies, but had no effect on student learning. When the reinforcement for the instructors was instead made contingent upon student learning, the student learning improved and the instructors' high level of training behaviors was maintained. In addition, the instructors began to request training for themselves. These findings suggest that staff motivation programs for instructors might usefully base the reinforcers not only on the instructor's performance, but on the progress of their students. 相似文献

The present study evaluated the effectiveness of self-monitoring, relaxation training and habit reversal in the treatment of 6 Tourette Syndrome (TS) subjects with multiple motor and vocal tics. A counterbalanced design was employed and tic frequencies were measured in the clinic setting using videotapes taken through a one-way mirror. Tics were reduced by an average of 55% with habit reversal, 44% with self-monitoring, and 32% with relaxation training and each behavioral procedure was the most effective treatment for at least one subject. All three treatment approaches may have some utility in the behavioral treatment of TS. 相似文献

Fingernail-biting is prevalent among children and adults alike. About 43% of children bite their nails during the puberty ages (Wechsler, 1931); 25% of college students are nail-biters (Coleman and McCalley, 1948), and 10% of adults bite their nails (Pennington, 1945).A variety of treatments including negative practice, operant procedures and psychotherapy have been used in treating nail-biting but no single treatment has been generally effective in eliminating nail-biting. Smith (1957) using negative practice reported that 21 of 57 (39%) of his nail-biting clients were cured. 9 improved and 27 (47%) were unimproved. Bucher (1968) reported that 13 of 20 (65%) college students stopped nail-biting by using a self-administered operant shock procedure. However, he reported many relapses after the withdrawal of shock for nail-biting. No evaluation of psychoanalytic treatment for nail-biting appears to have been made. 相似文献

A major problem in outpatient treatment has been the extreme irregularity with which patients use medication prescribed for them. As a new approach to resolving this problem, a portable operant apparatus was developed based on response priming and escape reinforcement. The apparatus sounded a tone at the time that a pill was to be taken. When the user turned a knob to terminate the tone, the apparatus delivered the pill into the user's hand. The apparatus was evaluated with six normal adults using a medically inert pill. A greater proportion of the pills were taken by each subject when using the special apparatus as compared with the use of a portable alarm timer or the usual wristwatch. These results demonstrate a new approach for increasing the regularity of self-administration of medicines. 相似文献

Research has revealed the phenomenon of conditioned suppression in which the rate of responding is reduced during a stimulus that is paired with noncontingent shock. The present study replicated this procedure, but used noncontingent positive reinforcers instead of the aversive shock. The lever-pressing responses of rats were reinforced with food or water. While the rats were responding, a stimulus was occasionally presented and paired with the delivery of a noncontingent positive reinforcer, which was either food, water, or brain stimulation for different rats. The result was a reduction in the rate of responding during the conditioned stimulus. This finding shows that conditioned suppression occurs during a signal for reinforcing as well as aversive stimuli. 相似文献
