A commonly associated side effect of extinction as a treatment for behavior disorders is an initial increased frequency of the target response, called an "extinction burst." This study analyzed 113 sets of extinction data and found that extinction bursting occurred in only 24% of cases and was less common when extinction was combined…

Functional analyses were conducted with four individuals with profound mental retardation whose self-injurious behavior (SIB) had relapsed after successful treatment (also based on functional analysis). For three subjects, this second analysis revealed that SIB had acquired new or additional functions. Results suggest reasons other than program…

To identify the most potent reinforcers for 10 young children with attention deficit hyperactivity disorder, the relative treatment utility of a verbal forced-choice questionnaire, child nomination, and direct observation was evaluated. Results demonstrated that all three methods were more likely to disagree than agree and that a forced-choice…

This study evaluated the effectiveness of high probability requests and time-out as treatments for noncompliance which appeared to be maintained by contingent attention in two developmentally normal children. The introduction of high-probability requests increased compliance for one child but not the other. Time-out was effective with both…

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.…

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…

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…

Using an ABAB design, two procedures for requesting a change of activity were compared for their effect on the stereotypic behavior of a man with autism. One procedure requested immediate change of activities, whereas the second procedure gave advance notice of a change. Less stereotypy occurred when advance notice of change was given. (Author/DB)

Evaluation of reductive treatment versus instructional treatments on the generalized reduction of problem behaviors in two adolescents with severe intellectual disabilities indicated that when only one member of a response class was blocked, a collateral increase in other problem behaviors was observed, but learning an alternative positive…

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)

A review of 158 applied behavior analysis studies with children as subjects, published in the "Journal of Applied Behavior Analysis" between 1980 and 1990, found that (1) 16% measured the accuracy of independent variable implementation, and (2) two-thirds did not operationally define components of the independent variable. Specific recommendations…

Three studies investigated environmental correlates of self-injurious behavior in seven developmentally disabled children and adolescents which were then later used for treatment. Correlates investigated included positive reinforcement, negative reinforcement, automatic reinforcement, and control. "Escape extinction" was successfully…

The study assessed whether 4 students (ages 9-13) with severe autistic disabilities could learn to use a self-management treatment package to reduce stereotypic behavior. Use of the procedures greatly reduced levels of stereotypic behavior. Improvement also occurred for extended periods of time in new settings without the presence of a treatment…

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)

Two case examples (a toddler with severe developmental delays and a 7-year old with severe mental retardation) illustrating effects of meal schedule and food quantity on displays of problematic behavior are offered. Brief functional analyses of aberrant behavior provided useful information for interpreting distinct patterns of behavior. (DB)
