Responding on concurrent-chains schedules in open and closed economies.

Pigeons' key pecks were reinforced according to concurrent-chains schedules of reinforcement. The programmed average time from the onset of the initial links to a terminal link entry was held constant across conditions while the value of variable-interval schedules in the terminal links was varied. Performance was assessed under two economic conditions: (a) an open economy in which session duration was limited to 1 hr and subjects were maintained at 80% of their free-feeding body weights with postsession food when necessary; and (b) a closed economy in which sessions were 23.5 hr long and no deprivation regimen was in effect. In all cases, the relative rate of responding in the initial links matched the reduction in overall delay to primary reinforcement correlated with entry into one terminal link relative to the reduction in delay correlated with entry into the other terminal link. Although the sum of responses made in the initial links and terminal links was found to increase, then decrease, as the rate of food presentation decreased in the closed economy, there was no consistent effect of overall rate of food presentation on total responding in the open economy. The choice data suggest that relative delay reduction predicts choice accurately, regardless of economic context.     

Idolatry: A Reading Key for the Market Economy?

This article proposes that theology can and must have a significant role in understanding current economic‐social reality. Using examples that portray the frequent use of religious terms among executives, economists, and political and social analysts, it shows that the discourse of the market system assumes a dogmatic faith in the market and that the theological concept of idolatry can be very useful in unveiling the system's fascination and sacrificial character.     

USE OF A TOKEN ECONOMY TO INCREASE COMPLIANCE DURING HEMODIALYSIS

We report the effects of using a token economy to treat noncompliant behavior in a 10-year-old male hemodialysis patient. The results of an ABAB design indicated that the intervention increased compliant behavior during both treatment phases and that compliance was maintained at 3- and 6-month follow-up observations.     

Why be my colleague’s keeper? Moral justifications for peer review

Justifying ethical practices is no easy task. This paper considers moral justifications for peer review so as to persuade even the sceptical individualist. Two avenues provide a foundation for that justification: self-interest (the right behaviour is that which maximally serves one’s own interests) and social contract theory (the right behaviour is that which best meets obligations set in binding social contracts). A wider notion of “interest” permits the self-interest approach to justify not only submitting one’s own work to peer review but also removing oneself momentarily from the production of primary knowledge to serve as a rigorous, independent, and honest referee. The contract approach offers a non-selfish alternative and relies on four types of binding social contracts: those implicit in accepting funds, those implicit in asserted professional status, those to contribute what is of most value to society, and those to defend the ideals of the Academy. Efforts to restore respect for rigorous, independent, honest peer review should begin in earnest.     

THE EFFECT OF A TOKEN ECONOMY ON DIETARY COMPLIANCE FOR CHILDREN ON HEMODIALYSIS

Adherence to dietary restrictions is a recurring problem for children on hemodialysis. The effect of behavior modification in maintaining dietary control is reported for four patients aged 11 to 18 years. Weight gain, potassium level, and blood urea nitrogen were utilized as criteria measures. A token reinforcement program implemented by the hemodialysis team resulted in significant changes in the dietary pattern of the children. The average weight gain between dialysis sessions for the four subjects during treatment was reduced by 45% and the degree of weight fluctuation was lessened. Potassium levels and BUN were controlled to their appropriate level for subjects who initially exceeded the criterion level. With the withdrawal of weight gain from the contingency system, increase of weight gain between dialysis sessions was noted for all subjects.     

THE EFFECTS OF TOKEN REINFORCEMENT ON THE BEHAVIOR OF DELINQUENTS IN COTTAGE SETTINGS1

A token economy designed to modify the behavior of 125 adolescent males committed to a state correctional institution was implemented in the boys' cottages, focusing on social behavior (peer interaction), rule following, and task completion. The program was sequentially introduced in a multiple-baseline design in three independent cottages; a fourth group served as a comparison cottage. Appropriate behavior increased when the token program was introduced in each cottage. Data were collected for 14 months. Thus, the long-term effects of initial behavior change were assessed.     

THE CELLBLOCK TOKEN ECONOMY: TOKEN REINFORCEMENT PROCEDURES IN A MAXIMUM SECURITY CORRECTIONAL INSTITUTION FOR ADULT MALE FELONS1

Two experiments were conducted (1) to explore the application of token reinforcement procedures in a maximum security correctional institution for adult male felons and (2) to determine to what extent the reinforcement procedures disrupted the day-to-day lives of inmate participants. In Experiment 1, an expanded reversal design revealed that the combination of praise and token reinforcement was more effective than the combinations of praise and noncontingent token award or direct commands on four common institutional activities. The latter two combinations were not found to be any more effective than praise alone. Experiment 2, which also employed a reversal design, indicated that the high levels of performance observed during the token reinforcement phases of Experiment 1 could be attained without subjecting participants to undue hardship in the form of increased deprivation of either social intercourse or the opportunity to engage in recreational and entertainment activities. Client safeguards are discussed in detail.     

Peer and college-student tutoring as reinforcement in a token economy

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.     

REPLICATION OF THE ACHIEVEMENT PLACE MODEL IN CALIFORNIA1

Attempting to replicate procedures from Achievement Place, token reinforcement procedures were used to modify savings, conversational interruptions, and table-setting of delinquent boys residing in a home-style, community based, treatment setting. The tokens (points) were redeemable for various privileges and could be earned for specified appropriate behaviors and lost for specified inappropriate behaviors. Contingent point fines reduced the frequency of interruptions. Point rewards improved table-setting, but even large point rewards did not substantially increase savings. Baseline data indicated that lateness to dinner was not a problem, as it was in Achievement Place. Withdrawal of contingent points and back-up rewards did not disrupt the clean-up behavior of two boys.     

AN INVESTIGATION OF THE EFFECTS OF TOKEN REINFORCEMENT ON DIVERGENT VERBAL RESPONDING1

The effect of token reinforcement on three classes of divergent verbal responding to verbal stimulus items from three measures of the Wallach-Kogan Creativity test was examined. The subjects consisted of two “gifted”, two “average”, and two “learning disabled” children from a public-school setting. The design utilized both an intra-subject and inter-subject multiple-baseline design with a reversal design added. Tokens were dispensed contingent upon the number of appropriate verbal responses to each stimulus item, i.e., a continuous schedule of reinforcement was used—one token per appropriate response. Interobserver agreement on “appropiateness” was 993%. The tokens could be used to “purchase” items listed in a “menu” format (e.g., ball and jacks—100 tokens). Consistently large effects of token reinforcement were observed, without generalization of effect across the three classes of behaviors, or conditions. These results support the works of Goetz and Baer (Journal of Applied Behavior Analysis, 1973, 6 , 209–217), Goetz and Salmonson (Behavior Analysis and Education, G. Semb, (Ed.), University of Kansas, 1972, 53–61), and Maloney and Hopkins (Journal of Applied Behavior Analysis, 1973, 6 , 425–434). Implications lie in continued experimental analysis of behavior approach to the concept called “creativity”. Additionally, implications are made in classroom application of assessing and intervening in the area of divergent responding for children with deficits in those areas.
