This study examined whether problem behaviors of three adults with profound mental retardation, which had been maintained by continuous reinforcement schedules, could be extinguished more rapidly than those maintained on an intermittent schedule of reinforcement. No significant differences in extinction rate were found between the two conditions.…

Although understanding how causal attributions for performance develop is important to attribution theory, little research has been done on this topic. To explore changes in attributions during task performance for both actors and observers, 90 female undergraduates participated in a procedure in which they received either 80 percent or 20 percent…

Expectancies of reinforcement from alcohol have been investigated from a variety of research perspectives. Although results vary with methodology, subject characteristics, and amount of alcohol consumed, research seems to indicate that the expectation of receiving alcohol influences, and at times outweighs, the actual pharmacological properties of…

The study investigated the effects of training two learning and behavior disordered elementary students to ignore the inappropriate behavior and to reinforce the appropriate behavior of three peers who were also learning and behavior disordered. Results indicated the students were able to utilize extinction and reinforcement procedures…

In this study with three children (ages four and five) with severe developmental disabilities and aberrant behavior maintained by tangible positive reinforcement, noncontingent reinforcement, and differential reinforcement of alternative behavior were found to decrease the frequency of aberrant behavior while strengthening mands. (Author/DB)

This study compared the effects of unequal and equal reinforcer duration during a functional analysis of aberrant behavior in an 11-year old with moderate mental retardation. Results showed that reinforcer duration affects the rate of aberrant behavior and may potentially alter functional analysis interpretation. (DB)

Noncontingent reinforcement (NCR) was applied to reduce the destructive behaviors of five-year-old quadruplets diagnosed with mental retardation and pervasive developmental disorder. Findings suggest that the effectiveness of NCR may be dependent on the use of a dense schedule of reinforcement initially and that systematic fading can increase the…

Functional assessment is redefining the standards for clinical interventions with problem behavior and reemphasizing the importance of basic behavioral mechanisms. It has shown the importance of complex patterns of behavioral control, functional assessment as an ongoing process, and the importance of attention to antecedent variables. Future…

After finding that self-injurious behavior in two young males with developmental disabilities was negatively reinforced by escape from instructional activities, an intervention provided noncontingent escape on a fixed schedule and differential negative reinforcement of other behavior. Provision of escape, even when noncontingent, resulted in…

A review of the January 1993 issue of the "Journal of the Experimental Analysis of Behavior" concludes that behavioral interventions produce collateral effects, but predicting those effects in applied work is complicated because of verbal and instructional influences and because of interactions among reinforcer types. (JDD)

This paper argues that behavior analysis is not technological to a fault, but rather has a faulty technology by being incomplete. The paper examines reinforcers and punishers that result from the outcomes of either (1) striving for better experimental control, or (2) inventing theories to explain why current control is imperfect. (JDD)

Two experiments with 15 individuals having profound mental retardation found difficulties in identifying reinforcers that were actually effective in treatment of chronic training needs. Research needs in evaluating training alternatives for people with profound multiple disabilities who move very little or who respond with very long latencies are…

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…

This study evaluated use of the interpolation of reinforcement effect, which combines intermittent (INT) and continuous reinforcement (CRF) schedules, with four young children with autism using a free-operant preparation. Results suggest that responding may be less resistant to extinction following interpolated CRF reinforcement than following INT…

Sensitivity to reinforcement contingencies was examined in six individuals with mental retardation using a concurrent operants procedure in the context of a computer game. Results included individual differences in sensitivity and differential sensitivity to rate and magnitude variation. Results suggest that comprehensive assessments of potential…
