The authors evaluated the effects of matched and unmatched stimuli on immediate and subsequent engagement in targeted vocal stereotypy (Experiment 1) and untargeted motor stereotypy (Experiment 2). Results of Experiment 1 showed that (a) matched stimulation decreased immediate engagement in vocal stereotypy for 8 of 11 participants and increased…

Stereotypy has been classified as repetitive behavior that does not serve any apparent function. Two procedures that have been found to reduce rates of vocal stereotypy effectively are response interruption and redirection (RIRD) and noncontingent access to matched stimulation (MS). The purpose of the current study was to evaluate the effects of…

A randomized pretest-posttest control group design was utilized to measure the effects of a platform swing on independent work behaviors of 30 children with Autism Spectrum Disorders (ASD). Participants engaged in two 5-min intervals of independent work. Between the intervals, participants in the treatment group received 5 min of vestibular…

Persons with severe to profound multiple disabilities, such as intellectual, visual, and motor disabilities, may be characterized by low levels of adaptive engagement with the environment. They may also display forms of inappropriate, stereotypical behavior (like hand mouthing, that is, putting their fingers into or over their mouths) or…

A naturalistic assessment of self-injurious behavior in an 11-year-old boy with multiple disabilities, including severe mental retardation, found that the boy's self-injury was occasioned by low attention and low stimulation and maintained by tangible and social reinforcement. Naturalistic assessment effectively guided the selection of behavioral…
