A system is described wherein adolescents participating in a token economy at a state hospital were allowed to appeal fines received from staff. Appeals were heard by a board composed of three residents and a psychology intern. The board met weekly and had full power to rescind or uphold fines. Before initiation of the appeal system, residents complained vigorously about fines received and about the "unfairness" of the staff and the token system, frequently denying responsibility for the infractions involved. Although almost half the fines were upheld, there were practically no more complaints of unfairness, and denials of responsibility declined drastically. The number of residents appealing fines fell from an average of four per week to less than one per week after the system had been in effect for one and one-half months. When asked why the system was not being used more often, residents grudgingly volunteered that most of the fines received were fair. It was not possible to determine whether this was due to changes in residents' attitudes or to actual changes in fining behavior by staff. Results are discussed in terms of effects on residents, acceptance by staff, and implications for further research.  相似文献

An inexpensive, easily managed token economy was used in a normal classroom for one academic year, and data were collected for the entire academic performance in spelling, language, handwriting, and math for that year. During a baseline period, assignment completion was variable. The introduction of a token economy with a point exchange every five days increased assignment completion and decreased variability of performance. An application of a token economy that had a point exchange averaging four days was accompanied by an assignment completion rate that approximated 100%. A reinforcement contingency for which quiet behavior rather than for assignment completion was eased quiet behavior was accompanied by a marked diminution of assignment completion. A reintroduction of the token reinforcement for assignment completion system increased assignment completion again.  相似文献

Eighteen long stay male patients (diagnosis chronic schizophrenia) were involved in a six month token economy prior to random assignment to one of three experimental groups to investigate the importance of social reinforcement and other token-related variables in maintaining improvements brought about by the token system. Assessment included standardised psychiatric rating scales, nurse rating scales, and behavioural measures. Analysis of variance suggests the full token economy system produced significant improvements, but that the social factors involved in token exchanges were not demonstrably important sources of reinforcement. and that none of the variables studies at the experimental phase were critical factors. Once patients returned to a complete token system, results indicate that this may have more value in the promotion of work activities rather than social responding. It is argued that the token system provides a necessary clear structure within which nurses can encourage continuous improvements with long stay patients.  相似文献

Token spending by 20 schizophrenic patients was monitored over a six-month period. It was found that: (1) token expenditures for cigarettes and "edibles" far surpassed other store item categories; and (2) percentage increases in token expenditures were greatest for categories of items relating to appearance and grooming, strongly suggesting that store purchasing patterns over time may provide an index of program effectiveness.  相似文献

Reports of token economy programs with hospitalized psychiatric patients are reviewed with emphasis on three general aspects of function :(1) effectiveness. (2) factors influencing effectiveness, and (3) experimental methodology. Token economies are effective in modifying a wide variety and range of patient behavior, but it is still unclear which variable or combination of variables operating in the program are primarily responsible for the changes effected. The methodological aspects of program evaluation were found to be less than adequate in most cases because of failure to control probable operational variables. A systems analysis of the token economy program was offered in which influential aspects of the program including feedback effects were recognized and accounted for in conceptualizing function and evaluation.  相似文献

Seven types of behavior of thirteen chronic schizophrenic female patients, who were transferred to an existing male token economy ward, were rated during four experimental phases. During Conditions I and III the patients were given a token allowance in the morning on a noncontingent basis. During Conditions II and IV tokens were paid on a contingent basis; that is, the patients received tokens commensurate with their behavior ratings. Their ratings were higher during Conditions II and IV than during Conditions I and III. The results supported the expectation that the contingent tokens were controlling the behavior of the patients.  相似文献

Eighteen second-grade children initially received feedback in the form of nonredeemable tokens for reducing their disruptive classroom behavior. Four types of tutoring were then introduced in a Latin Square Design: noncontingent tutoring from fifth-grade peers, contingent peer tutoring, noncontingent college tutoring, and contingent college tutoring. No significant difference was found in the level of disruptive behavior of those children tutored by fifth-grade peers or college students, but contingent tutoring was significantly effective in reducing disruptive classroom behavior.  相似文献

Adolescents on a 16-bed token economy ward of a state hospital were subjected to four interventions in a seven-phase experiment to reduce the number of fines they received each day. Phase I was a four-week baseline period. Phases II and III were four- and five-week periods, respectively, in which residents were awarded tickets for a weekly $10 lottery each day they were at or below a changing criterion of daily fines. In Phase IV, residents received coupons, exchangeable for money, for days with zero fines. Phase V was a return to baseline. Phase VI was a one-week period in which daily lotteries for $1 were held, with the criterion for receiving a ticket being zero fines on the previous day. Phase VII was a one-week return to baseline. No significant differences in average fines per day, number of residents meeting criteria, or mean number of zero-fine days per week were found across phases. Results are discussed in terms of amount and immediacy of reinforcement, other opportunities to gain money, possible rebelliousness of the residents against the increased aversiveness of fines, and implications for further research.  相似文献

Token economies are rarely used in real-world psychiatric settings because of barriers to their implementation, such an institutional constraints and insufficient collegial support. The line-level treatment team at Elgin Mental Health Center was able to overcome these contraints and develop a user-friendly token economy. This article describes Elgin's simple yet effective token economy and the process used to develop it.  相似文献

After systematic attempts to increase a teacher's positive responding to her first-grade students, a token-economy system was implemented as a "last resort". On-task student behavior and relative frequency of positive and negative teacher comments were systematically observed. Data indicated that institution of the token system was associated with a relatively higher percentage of positive than negative comments. Termination and re-implementation of the token system caused reversals of the teacher's behavior.  相似文献

Token economies have been applied in a wide range of settings. While there are several advantages to the use of this procedure, there are obstacles that may impede its implementation and therapeutic efficacy. These include: staff training, client resistance, circumvention of the contingencies, and non-responsiveness of subjects. Studies employing token programs with psychiatric patients, retardates, children in classroom settings, delinquents, and autistic children are reviewed. Although token economies are successful while in operation, the issue of generalization of behavior gains or resistance to extinction has not been given careful consideration. Inasmuch as generalization is perhaps the most crucial issue, several procedures are presented that are designed to facilitate maintenance of performance when reinforcement is withdrawn. Methodological suggestions for investigations on token reinforcement in applied settings are presented.  相似文献

We presented four chimpanzees with a series of tasks that involved comparing two token sets or comparing a token set to a quantity of food. Selected tokens could be exchanged for food items on a one-to-one basis. Chimpanzees successfully selected the larger numerical set for comparisons of 1 to 5 items when both sets were visible and when sets were presented through one-by-one addition of tokens into two opaque containers. Two of four chimpanzees used the number of tokens and food items to guide responding in all conditions, rather than relying on token color, size, total amount, or duration of set presentation. These results demonstrate that judgments of simultaneous and sequential sets of stimuli are made by some chimpanzees on the basis of the numerousness of sets rather than other non-numerical dimensions. The tokens were treated as equivalent to food items on the basis of their numerousness, and the chimpanzees maximized reward by choosing the larger number of items in all situations.  相似文献
