The TARPA (Training & Assessment of Relational Precursors & Abilities) is a recently developed computer-based protocol for the assessment of a progression of key domains of responding critical to the development of generative language. In the current pilot study, five children with autism were assessed using the TARPA and their score on this protocol was correlated with ratings on the Vineland Adaptive Behavior Scales. Findings showed a statistically significant correlation. This and other features of TARPA performance and their implications for future testing and development of this protocol are discussed.
In a class inclusion task, a child must respond to stimuli as being involved in two different though hierarchically related categories. This study used a Relational Frame Theory (RFT) paradigm to assess and train this ability in three typically developing preschoolers and three individuals with autism spectrum disorder, all of whom had failed class inclusion tests. For all subjects, relational training successfully established the target repertoire and subsequent testing demonstrated both maintenance and generalization. Limitations and future research directions are discussed.
Stereotyped, repetitive, ritualistic, obsessive, and compulsive behaviors are a common feature for many individuals with autism, and multiple topographies of such behavior exist. Previous reviews have discussed treatments for stereotypy and repetitive behaviors; however, to date, none have systematically evaluated the efficacy of such treatments. An abundance of treatments based on the principles of applied behavior analysis exist within the literature; however, many assume that stereotypy is maintained by automatic reinforcement. The current review aimed to evaluate the efficacy of treatments for stereotypy across disciplines including behavioral, pharmacological, and sensory-based therapies. Furthermore, this review compares the efficacy of function-based and nonfunction-based treatments for stereotypy.
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.
