We compared the effects of Lag 0 and Lag 1 schedules of reinforcement on children's responses naming category items in a group context and subsequent responses emitted during individual testing in which the schedule of reinforcement remained Lag 0. Specifically, we measured response variability and novel responses to categories for 3 children who…

One of the key diagnostic criteria for autism spectrum disorder includes impairments in social interactions. This study compared the extent to which boys with high-functioning autism and typically developing boys "value" engaging in activities with a parent or alone. Two different assessments that can empirically determine the relative…

Adolescents with Emotional and Behavioral Disorders (EBD) present deficits in literacy skills, in part because their disruptive behaviors interfere with task engagement. Antecedent manipulations, such as those based on behavioral momentum theory, can increase students' contact with reinforcement, leading to greater task engagement. This study…

School districts are in the process of adopting the Response to Intervention (RTI) approach to identify and remediate academic and behavioral deficits. As an integral member of the school behavior team, school counselors must use data on individual interventions to contribute to the data-based decision making process in RTI. This article presents…

Children with autism spectrum disorders (ASD) have a high prevalence of specific fears, including fear of general medical procedures, but research on the treatment of medical fears has been limited. Two studies are described in this article. The first study involved an assessment of the prevalence of fears associated with physical exams.…

This study extends previous work on the use of differential observing responses (DOR) to remediate atypically restricted stimulus control. A participant with autism had high matching-to-sample accuracy scores with printed words that had no letters in common (e.g., "cat," "lid," "bug") but poor accuracy with words that had two letters in common…

This study evaluated the effects of using differential reinforcement of other behavior (DRO) with a differential reinforcement of alternative behavior (DRA) resetting time schedule to reduce stereotypy in a child with Rett Syndrome. The primary purpose of the investigation was to compare latency and choice as dependent measures to identify…

Two normal and two mentally retarded children were trained to earn pennies by pressing a key according to a multiple variable-interval extinction schedule of reinforcement. Retarded children differed from normal children by producing more positive than negative discriminative stimuli. (Author/DB)

Effects of three intervention procedures were compared in increasing academic achievement and level of appropriate behavior for children with relatively low rates of appropriate behavior. A significant experimental/control group difference, favoring experimentals, was found for reading and math achievement and level of appropriate behavior.…
