Using food aversion to decrease severe pica by a child with autism.

Food aversion was shown to be effective in the reduction of plastic pica by a 4-year-old boy with autism. The participant was suffering from digestive complications due to the ingestion of plastic from a variety of toys. The intervention was initially conducted in the child's preschool classroom during instructional periods and was systematically generalized to the entire preschool classroom, and eventually to both classrooms within the preschool and across 25 teachers. The success of the intervention in decreasing pica was enhanced by its achievement in not reducing interactions with toys, considering appropriate play skills were a target goal.

A preliminary analysis of teaching improvisation with the picture exchange communication system to children with autism.

Two young boys with autism who used the picture exchange communication system were taught to solve problems (improvise) by using descriptors (functions, colors, and shapes) to request desired items for which specific pictures were unavailable. The results of a multiple baseline across descriptors showed that training increased the number of improvised requests, and that these skills generalized to novel items, and across settings and listeners in the natural environment.

A comparison of interteaching and lecture in the college classroom.

Interteaching is a new method of classroom instruction that is based on behavioral principles but offers more flexibility than other behaviorally based methods. We examined the effectiveness of interteaching relative to a traditional form of classroom instruction-the lecture. In Study 1, participants in a graduate course in special education took short quizzes after alternating conditions of interteaching and lecture. Quiz scores following interteaching were higher than quiz scores following lecture, although both methods improved performance relative to pretest measures. In Study 2, we also alternated interteaching and lecture but counterbalanced the conditions across two sections of an undergraduate research methods class. After each unit of information, participants from both sections took the same test. Again, test scores following interteaching were higher than test scores following lecture. In addition, students correctly answered more interteaching-based questions than lecture-based questions on a cumulative final test. In both studies, the majority of students reported a preference for interteaching relative to traditional lecture. In sum, the results suggest that interteaching may be an effective alternative to traditional lecture-based methods of instruction.

Effects of guided notes versus completed notes during lectures on college students' quiz performance.

We compared the effects of guided lecture notes versus completed lecture notes on pre- to postlecture improvements in quiz performance across two sections of a college course. The results of a counterbalanced multielement design did not reveal consistent differences between the two note formats on students' mean quiz scores. However, fewer errors occurred on complex (analysis-level) quiz questions in the guided notes condition than in the completed notes condition.

Behavioral assessment of impulsivity: a comparison of children with and without attention deficit hyperactivity disorder.

We conducted a brief computer-based assessment involving choices of concurrently presented arithmetic problems associated with competing reinforcer dimensions to assess impulsivity (choices controlled primarily by reinforcer immediacy) as well as the relative influence of other dimensions (reinforcer rate, quality, and response effort), with 58 children. Results were compared for children with attention deficit hyperactivity disorder (ADHD) who were and were not receiving medication, and with typically developing children without ADHD. Within-subject and between-groups analyses of the ordinal influence of each of the reinforcer dimensions were conducted using both time- and response-allocation measures. In general, the choices of children with ADHD were most influenced by reinforcer immediacy and quality and least by rate and effort, suggesting impulsivity. The choices of children in the non-ADHD group were most influenced by reinforcer quality, and the influence of immediacy relative to the other dimensions was not statistically significant. Results are discussed with respect to the implications for assessment and treatment of ADHD.
