“…Matched stimulation in the form of white noise was selected to target the putative automatic auditory consequences produced by his vocalizations. Matched stimulation, involving continuous access to stimuli that delivers sensations similar to the putative sensory consequences for the target behavior (e.g., noncontingent access to music), is an evidence-based intervention for reducing daytime vocal stereotypy in children on the autism spectrum Wang et al, 2020). The mechanism underlying the effects of matched stimulation is unclear; however, it is possible that consumption of the alternative auditory consequence satiates the child (i.e., is an abolishing operation), thereby reducing the child's motivation to engage in vocal stereotypy Michael, 1982).…”

“…For example, in a recent case analysis by McLay et al (2021a) of 41 children and adolescents on the autism spectrum with sleep problems, 27% of participants exhibited stereotypy in the sleep context. Stereotypic behaviors in children on the autism spectrum are heterogeneous, but can broadly be classified as either motor stereotypy, consisting of motor movements (e.g., hand-flapping, body-rocking), repetitive manipulation of objects (RMO; e.g., mouthing or spinning objects), or vocal stereotypy, involving non-contextual vocalizations (i.e., without a clear communicative purpose, e.g., recurring words or non-word sounds; Ahearn et al, 2007;Akers et al, 2020;Cunningham & Schreibman, 2008;DiGennaro Reed et al, 2012;Wang et al, 2020). All forms of stereotypy share a response topography of repetition, invariance, and atypicality (Didden et al, 2012;Rapp & Vollmer, 2005).…”

“…There is also evidence to suggest that stereotypy can be socially mediated, through contingencies of positive (e.g., social attention) and negative (e.g., escape from demands) reinforcement (Durand & Carr, 1987;Kennedy et al, 2000;Roantree & Kennedy, 2006;Wilke et al, 2012). Without intervention, stereotypy tends to persist throughout the lifespan and may increase in frequency and intensity over time (Akers et al, 2020;Bodfish et al, 2000;Wang et al, 2020).…”

“…Stereotypy can be problematic when the intensity of and/ or persistence in the behavior impedes an individual's adaptive functioning; for example, stereotypy can significantly interfere with socialization and learning in children on the autism spectrum (Akers et al, 2020;Lydon et al, 2017;Wang et al, 2020). Stereotypy can also disrupt family functioning and is associated with severe parental stress (Boyd et al, 2012).…”

“…Stereotypy can also disrupt family functioning and is associated with severe parental stress (Boyd et al, 2012). As such, stereotypy is a common target for intervention, particularly in the educational setting (Akers et al, 2020;Wang et al, 2020). There is also evidence to suggest that stereotypy may serve as a coping mechanism for individuals on the autism spectrum, possibly helping to alleviate distress and to regulate thoughts and feelings (Gabriels et al, 2005(Gabriels et al, , 2013McCarty & Brumback, 2021).…”

Objectives Sleep problems in children on the autism spectrum may be affected by core diagnostic characteristics, including stereotypy (restricted and repetitive behaviors). Little is known about the nature of sleep-related stereotypy and its role within sleep disturbance. This study aimed to improve our understanding of the types of sleep-related stereotypy, its potential role within sleep difficulties, and how parents manage night-time stereotypy, in children on the autism spectrum. Methods This qualitative study used thematic analysis to analyze clinical assessment reports obtained from 21 parents of children on the autism spectrum referred for behavioral sleep intervention. Five themes, including the types of stereotypy, timing within sleep problems, stereotypy as sleep-interfering, stereotypy as sleep-conducive, and parent-responses, were identified. A clinical case study illustrates the potential role of vocal stereotypy within night wakings, through functional assessment and treatment of sleep problems in a child on the autism spectrum. Results Stereotypy included vocal and motor behaviors and repetitive manipulation of objects. Parents perceived stereotypy as both problematic and as beneficial to sleep, which may differentially affect behavioral treatment. Parent responses to stereotypy were varied and included co-sleeping. The case study highlights the complexity of the sleep and stereotypy relationship and the difficulty in treating automatically maintained behavior in the sleep context. Conclusion The function that stereotypy serves in relation to sleep disturbance is unclear and may differ across and within children. It is important we seek to better understand the specific ways that stereotypy may affect sleep, and vice versa, to improve clinical management of sleep problems in children on the autism spectrum.

Individuals with Autism Spectrum Disorder may engage in repetitive vocal behaviors which interfere with a structured environment and social inclusion. If untreated, these vocal behaviors maintain into adulthood potentially impeding gainful employment and independent living. This analysis specifically focused on treatments available for presumed or functionally determined automatically reinforced repetitive vocal behaviors, also known as vocal stereotypy. For this review, a systematic keyword search of the literature identified 66 articles and a Tau-U measure of effect size was calculated for 34 eligible studies in order to determine impact of interventions on vocal stereotypy. Of the single-component interventions assessed, three interventions demonstrated a very large effect: interactive activity (0.94), self-management (0.89), and response interruption and redirection (interrupted measurement, 0.86). Additionally, 92% of treatment packages reached a very large effect (0.85-1.00), all of which included stimulus control and/or response cost intervention components. Theoretical and practical applications are discussed, as well as implications for future research.

The effects of sensory integration on stereotypy of preschool students with autism

The purpose of the current study was to systematically replicate the independent variable used in Moore et al.'s (2015) experiment using sensory integration therapy (SIT) as a treatment for automatically maintained stereotypy. According to sensory integration theory, providing certain sensory experiences to individuals with autism can change their repetitive behavior. Despite the lack of research supporting SIT as a valid treatment to reduce episodes of stereotypy in individuals with autism spectrum disorder (ASD), it remains a common treatment in most schools and centers designed for these individuals. The study was conducted with three preschool students with ASD using a multiple baseline design across participants to test for a functional relation between the independent variable, the participants' individualized, prescribed sensory diets and the dependent variable, their episodes of stereotypy in morning and afternoon sessions. The results do not support the use of a sensory diet as a treatment for stereotypy.
