Individuals with autism spectrum disorder (ASD) often have few employment opportunities and a lower job quality than individuals of typical development. Social deficits and lack of independence may contribute to underemployment and unemployment of individuals with ASD. The ability to solve problems might ameliorate some of these barriers. We…

Of the diagnostic features of autism, relatively little research has been devoted to restricted and repetitive behavior, particularly topographically complex forms of restricted and repetitive behavior such as rigidity in routines or compulsive-like behavior (e.g., arranging objects in patterns or rows). Like vocal or motor stereotypy,…

We evaluated antecedent exercise for treating the automatically reinforced problem behavior of 4 individuals with autism. We conducted preference assessments to identify leisure and exercise items that were associated with high levels of engagement and low levels of problem behavior. Next, we conducted three 3-component multiple-schedule…

We evaluated the evocative effects of four conditions (high- and low-preference activities, low and divided attention) and stimulant medication on the behavior of a 16-year-old boy with attention deficit hyperactivity disorder and moderate mental retardation. All behavior (activity engagement, activity changes, inappropriate touching, rude…

Social skills deficits are a defining feature of individuals diagnosed with autism and other pervasive developmental disorders (PDD), which can impair functioning and put the individual at higher risk for developing problem behavior (e.g., self-injury, aggression). In the current study, an adolescent with PDD displayed inappropriate social…

Differential reinforcement of alternative behavior (DRA) is used frequently as a treatment for problem behavior. Previous studies on treatment integrity failures during DRA suggest that the intervention is robust, but research has not yet investigated the effects of different types of integrity failures. We examined the effects of two types of…

The current study evaluated the use of various behavioral measures of running away with regard to (a) the differential utility of interval- versus event-based measures, (b) the differential utility of rate versus duration measures, (c) the utility of correcting for occurrence opportunity, and (d) the influence of unit of analysis (i.e.,…

A study involving three individuals (ages 13-20) with developmental disabilities and problem behaviors examined the influential role that unanticipated idiosyncratic stimulus variables play in affecting the outcome of a functional analysis. Guidelines are discussed concerning when to suspect that idiosyncratic stimuli might be acting to influence…

The effects of signaling the return of items or attention during treatment with noncontingent reinforcement were examined. First, functional analyses showed that the problem behavior exhibited by 2 teenagers with developmental disabilities was sensitive to social positive reinforcement. Next, delivery of the stimulus that maintained problem…

Fjellstedt and Sulzer-Azaroff (1973) used differential reinforcement of short latencies to decrease a child's latency to comply with instructions. We replicated this contingency with a young man diagnosed with Asperger syndrome across two tasks (question answering and math problem solving). We added a differential reinforcement contingency to…

The results of a functional analysis of problem behavior and a paired-choice assessment were compared to determine whether the same social reinforcers were identified for problem behavior and an appropriate response (time allocation). The two assessments were conducted in classroom settings with 4 adolescents with mental retardation who engaged in…

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…

Functional analysis conducted during a 90-minute evaluation session identified maintaining variables for aggressive behavior and an alternative replacement response in 3 individuals with severe handicaps. During a subsequent contingency reversal phase, aggressive behavior was substantially reduced and alternative behavior increased. Results…

A behavioral assessment procedure was evaluated with five children with severe/profound mental retardation who exhibited feeding problems of limited intake. Subjects were fed various types of foods. Results indicated each subject fit into one of four categories: (1) total food refusal, (2) food type selectivity, (3) food texture selectivity, or…

Three experiments were conducted with two participants with mental retardation that displayed property destruction and stereotypy. The experiments assessed the function of the responses, determined their relationship, and developed a treatment to reduce property destruction. Response blocking reduced property destruction (and attempts), prevented…
