Grammar is frequently considered to be a strength in the cognitive profile of individuals with autism spectrum disorders (ASDs); however, few studies have investigated how abstract (i.e., distinct from specific lexical items) is the grammatical knowledge of individuals with ASD. In this study, we examine the extent to which children with ASD have abstracted the transitive (SVO) frame in English. Participants in a longitudinal study of language acquisition in children with autism (17 children with ASD averaging 41 months of age, 18 TD children averaging 28 months of age) were taught two novel verbs in transitive sentences and asked (via intermodal preferential looking) whether these verbs mapped onto novel causative vs. noncausative actions. Both groups consistently mapped the verbs onto the causative actions (i.e., they engaged in syntactic bootstrapping). Moreover, the children with ASD’s performance on this task was significantly and independently predicted by both vocabulary and sentence-processing measures obtained eight months earlier. We conclude that many children with ASD are able to generalize grammatical patterns, and this ability may derive from earlier lexical and grammatical knowledge.
The effectiveness of an intervention package involving self-management and a group contingency at increasing appropriate classroom behaviors was evaluated in a sample of middle school students. Participants included all students in each of the 3 eighth-grade general education classrooms and their teachers. The intervention package included strategies recommended as part of best practice in classroom management to involve both building skill (self-management) and reinforcing appropriate behavior (group contingency). Data sources involved assessment of targeted behaviors using Direct Behavior Rating-single item scales completed by students and systematic direct observations completed by external observers. Outcomes suggested that, on average, student behavior moderately improved during intervention as compared to baseline when examining observational data for off-task behavior. Results for Direct Behavior Rating data were not as pronounced across all targets and classrooms in suggesting improvement for students. Limitations and future directions, along with implications for school-based practitioners working in middle school general education settings, are discussed.
The purpose of this study was to provide initial evaluation of a web-based training module on rating accuracy when using Direct Behavior Rating (DBR). Components of the training module included (a) an overview familiarizing users with assessing student behavior with this method, (b) modeling that includes frame-ofreference training, and (c) multiple opportunities to practice and receive immediate corrective feedback. Participants included 90 undergraduate students assigned to one of six sessions (three experimental and three control). Rating accuracy served as the outcome measure defined as the difference between the rater score and a comparison derived from an expert DBR or systematic direct observation (SDO) score. Rating targets included academically engaged, disruptive, and respectful behavior. Completion of the DBR training module generally yielded ratings that more closely compared with the scores obtained via DBR experts and SDO, yet specific results were mixed across type of rating (i.e., behavior target and duration) and comparison (i.e., DBR expert and SDO). Limitations, future research directions, and implications for practice are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
