Stereotypy has been defined as repetitive vocal or motor behaviors that are noncontextual with invariant topographies. One intervention to reduce vocal stereotypy and increase appropriate vocalizations is response interruption and redirection (RIRD). Previous research has suggested that RIRD's behavioral mechanism consists of punishment. The purpose of this study was to extend this research by comparing two procedures, namely, vocal and motor RIRD contingent upon the occurrence of vocal stereotypy and to evaluate concomitant increases in appropriate vocalizations. A multiple treatment reversal design was used to compare the effectiveness of both interventions on five children diagnosed with an Autism Spectrum Disorder. Results suggested that both demand topographies were equally effective in reducing vocal stereotypy and increasing appropriate vocalizations. This research replicates previous findings that have suggested that RIRD is a punishment procedure.

The current study compared the reductive effects of response interruption and redirection (RIRD) and competing items (including sound-producing and nonsound-producing toys) on the vocal stereotypy exhibited by two children diagnosed with Autism Spectrum Disorder. Sound-producing toys reduced vocal stereotypy relative to nonsound-producing toys and RIRD reduced stereotypy and increased rates of appropriate vocalizations to a greater extent than providing competing items. These findings replicate and extend previous literature suggesting that RIRD and sound-producing competing items are effective methods to treat vocal stereotypy.

Individuals diagnosed with intellectual and developmental disabilities (IDD) frequently exhibit self-injurious behavior (SIB). Previous research has examined the published literature on behavioral treatments of SIB from 1964–2000. Results suggested that these treatments were highly efficacious at decreasing SIB, particularly when based on the results of a functional assessment. The purpose of this review is to update, replicate, and extend the previous research. The current findings indicate an increase in studies reporting automatically maintained SIB as well as less efficacious treatments overall. Discussion of our conclusions and methods of SIB assessment and treatment are discussed, both as they relate to the previous review and for future directions.
