The pecking response of pigeons was reinforced when a minimum period of time had elapsed since the last response (DRL schedule of food-reinforcement). Punishment, satiation, extinction, and stimulus change were employed separately to reduce responding. When the effects of the four procedures were compared, punishment was found capable of producing a more immediate, complete and long lasting response reduction than the others. Punishment had its maximum effect on the responses that were least relevant to reinforcement. The punishment reduced the frequency of the short inter-response times to a greater extent than did either extinction or satiation. In this way, punishment actually increased the efficiency of the DRL responding. 相似文献

Escape responses of squirrel monkeys were reinforced according to a fixed-ratio schedule. The reinforcement was a period of safety from a stimulus that signalled the delivery of intermittent pain-shocks. When the frequency of shock was gradually reduced, the performance remained at a high level until the shocks were quite infrequent. Similarly, the duration of the period of safety could be reduced to a few seconds with little loss of behavior. Thus, the responses appeared to be reinforced by even a brief period of safety, the actual degree of shock reduction being fairly slight. The changes in responding during this fixed-ratio escape procedure were comparable to the response changes typically obtained during fixed-ratio food procedures. 相似文献

ABSTRACT A single-case controlled study found that a bulimic's desire to vomit was virtually eliminated by slowed eating, but not by rapid eating. The present study attempted to determine whether this same relation was exhibited by a larger number (N = 6) of bulimics who were instructed to eat at a fast or a slow rate in a between-subjects reversal design. For all 6 participants, the urge to vomit was found to be greater during fast versus slow eating after comparable amounts of food intake. Clinically, these results suggest that eating slowly might be incorporated into treatment for bulimic vomiting. 相似文献

ABSTRACT Behavioral psychologists have developed effective methods of treatment for overeating and weight control, including mealtime regulation, avoidance of taboo foods, and removal of identified precursors to the bingeing behavior. The current study sought to examine the relationship between speed of eating and levels of satiation in weight conscious individuals. Ten participants were instructed to eat at a fast and a slow rate in a within-subjects reversal design. Consuming food at a slow rate helped participants achieve satiation quicker with comparable amounts of food intake. Slow eaters were also less likely to overeat. These results suggest that slow eating may prevent excessive food consumption in weight conscious individuals, constituting an effective means of weight management. 相似文献

82 Ss were studied in a comparative evaluation of a behavioral vs supportive treatment for illegal drug use. Behavioral treatment included stimulus control, urge control, contracting/family support and competing response procedures for an average of 19 sessions. 37% of Ss in the behavioral condition were drug-free at 2 months, 54% at 6 months, and 65% at 12 months vs 20 ± 6% for the alternative treatment during all 12 months. The behavioral treatment was more effective across sex, age, educational level, marital status and type of drug (hard-drugs, cocaine, and marijuana). Greater improvement for this condition was also noted on measures of employment/school attendance, family relationships, depression, institutionalization and alcohol use. 相似文献
