This paper reviews the functional properties and procedural variations of differential reinforcement for the reduction of behavior disorders in individuals with developmental disabilities. The paper proposes that limited success may be a result of the arbitrary relationship that exists between reinforcers and target behaviors when behavioral…

This study evaluated the effectiveness of a brief, 2-minute pre-session stimulus preference assessment in predicting the levels of responding of four students (ages 6-9) with profound multiple disabilities. Use of the identified preferred stimulus resulted in higher levels of student responding during the instructional condition across all four…

The study evaluated the effects of a time-efficient reinforcer assessment package with three preschoolers with autism. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, and yielded expected improvements in accuracy. (Author/DB)

This study examined how 3 students (ages 14-18, with emotional or behavioral disorders) allocated their responding across 2 concurrently available tasks associated with unequal rates and equal versus unequal qualities of reinforcement. It found that time allocated to concurrent response alternatives was approximately proportional to obtained…

An experimental analysis of imitation was conducted to examine the influence of response topography on generalization of imitation across three response types with four children (ages two to four) with autism. The study found that imitation generalized from reinforced training models to nonreinforced probe models within a response type but did not…

This response to four papers on the nature of reinforcement focuses on the implications for application of theory to practice. The response addresses: reversibility of single-incentive selective associations; response deprivation, reinforcement, and economics; the substitutability of reinforcers; and delay reduction. (DB)

This study found that, compared to measuring approach behaviors to a variety of stimuli, a forced-choice stimulus preference assessment used with four young children with severe mental retardation resulted in greater differentiation among stimuli and better predicted which stimuli would result in higher levels of responding when presented…

Obscene verbalizations in an individual with traumatic brain injury were treated using stimulus fading as the singular form of intervention. Results of a functional assessment revealed the obscenity was maintained by negative reinforcement. Stimulus fading (the gradual reintroduction of instructional demands) produced immediate and substantial…

This paper presents a method for distinguishing between extinction and punishment effects. In extinction and punishment, different schedules of reinforcement or punishment are in effect when a given proportion of responses is blocked. Response patterns in treatment of hand mouthing in an adult with profound mental retardation suggest that a…

Behavioral analysis of reinforcers, adversities, and responses to adversities in videotapes of 14 college basketball games found that a team's favorable response to an adversity increased as the rate of reinforcement increased 3 minutes preceding the adversity and that calling time-outs was an effective intervention for reducing the opponent's…

Discusses the nature of control, examining how organisms as control systems sense or monitor the variable being controlled when responding to environmental changes. Argues that learning is the development of control in an attempt to fit the two phenomena central to traditional learning theory--conditioning and reinforcement--into the broader…

Seven adults with severe to profound mental retardation participated in match-to-sample discrimination training under three conditions. Results indicated that error-correction procedures improve performance through negative reinforcement; that error correction may serve multiple functions; and that, for some subjects, trial repetition enhances…

Describes two experiments that examined the conditions determining age changes in novelty preferences of children. (HOD)

Basic and applied research on variables that influence the extinction of operant behaviors is reviewed and applied to the treatment of behavior disorders. The potential value of a general technology for the use of behavioral extinction is discussed. The paper concludes that current research findings are not sufficient for the development of a…

Discussion of the functional relationship between self-injurious behavior (SIB) and self-restraint in people with severe disabilities considers SIB and self-restraint as members of the same functional response class, SIB and self-restraint as functionally independent responses, access to self-restraint as positive reinforcement of SIB, termination…
