The ability of a reinforcer to maintain behavior decreases as a hyperbolic function of its delay. This discounted value can help explain impulsivity defined as the choice of an immediate, small reinforcer over a delayed, large reinforcer. Human operant studies using consumable reinforcers such as videos have found impulsivity with delays under 1…

This series of papers was presented in a symposium on behavior therapy. Each paper represents a separate study focusing on one aspect of behavior modification. The issue of reinforcement is prominant with regard to its type and source. Methods of self-reinforcement and older-peer modeling are studied. The suggestion that subjects who reinforce…

Manipulation of mechanical restraint properties were conducted in separate studies with two profoundly retarded adolescents who exhibited both self-restraint and self-injurious behavior. Techniques included prompting, differential reinforcement, and stimulus fading. Results suggested that stimulus fading and transfer may be valuable components in…

Three case studies demonstrated excessive alcohol drinking in adolescents could be reduced by self-monitoring and extrinsic reinforcement procedures. Behavioral interventions resulted in complete abstinence for a male with 10 years of excessive alcohol abuse. However, alcohol abuse increased markedly for two females once intervention procedures…
