- W2294225523 abstract "The purpose of the study was to evaluate the effectiveness of sensory activities used as antecedent interventions on the percentage correct on academic tasks and rate of aberrant behavior in three elementary aged children with Autism Spectrum Disorders (ASD). Study activities were conducted in an after school program for children with ASD where program personnel acted as change agents regarding strategy implementation. An alternating treatment design was used with each participant to evaluate the differentiated effects of three activities. Results varied across participants regarding the sensory related activity that had the greatest effects on producing correct academic responses and reduction in aberrant behavior. In addition, sensory activities had greater effects than control sessions across all participants. A discussion of limitations and future research directions is included. Autism spectrum disorder (ASD) is a complex developmental disability affecting the lives of over 1.5 million Americans. According to the Centers for Disease Control and Prevention (2014), 1 in 68 children born today will eventually be diagnosed with ASD. In sum, the incidence and prevalence rates of ASD appear to be growing at high rates. Described first by Leo Kanner in 1943 through the case histories of 11 children, these individuals differed significantly from other children; therefore, he recommended that a separate diagnosis was necessary to describe their unique characteristics. Since Kanner’s first description of autism, the disorder has evolved into a spectrum disorder (i.e., ASD) with the percentage of diagnosed individuals increasing each year (Autism Society of America, 2007). The essential features of ASD include significant impairments in social interaction, communication skills and a highly restricted area of activities and interests (American Psychiatric Association, 1994). The latter category may be more specifically analyzed in terms of restricted, repetitive, and stereotyped patterns of behavior, interests, and activities. Children with ASD often demonstrate a preoccupation with idiosyncratic interests to a level considered abnormal in intensity and focus (American Psychiatric Association, 1994). For example, a child may know about the makes and models of trains and sustain conversations related to this topic for hours, but remain unable to engage in conversations about other topics. Further, many children with ASD have stereotyped and repetitive motor mannerisms (e.g., hand flapping). For example, a child may engage in repeated hand flapping, for no apparent functional purpose such as attention or escape. Several researchers have hypothesized that the function of these stereotyped behaviors are due to difficulties in processing sensory information and may result in other aberrant behaviors which children engage in to regulate environmental stimulation (Baranek, Foster, & Berkson, 1997; Paluszny, 1979). Significant unusual reactions to various types of sensory experiences in individuals with ASD have been discussed in the literature for decades (Baranek, Wakefield, & David, 2008) and hypothesized to the result of differCorrespondence concerning this article should be addressed to G.

Researchers within the behavior analytic field have purported that behaviors related to these areas are automatically reinforced (Hanley, Iwata, & McCord, 2003; Iwata et al., 1994). When determining the function of these behaviors, social mediation (e.g., access to tangible, attention, escape from task demand) are ruled out (Querim, Iwata, Roscoe, Schlichenmeyer, Ortega, & Hurl, 2013). When this occurs, the function of the behavior is considered to be automatically reinforced either through automatic positive reinforcement (i.e., seeking sensory input) or automatic negative reinforcement (i.e., escaping sensory input). Individuals with ASD demonstrate social participation challenges that involves functions that are associated with an atypical central nervous system (Bauman, & Kemper, 2003; Courchesne, Carper, & Akshoomoff, 2003). Increasingly, the literature describes the way in which the brain differentiates sensory integration and praxis dysfunction (Crane, Goddard, & Pring, 2009; Dawson & Lewy, 1989; Dawson & Watling, 2000; Smith & Bryson, 1994). Rogers & Ozonoff (1994) report significant incidences of sensory sensitivities and sensory perception deficits in a sample of individuals with autism, suggesting neurological abnormalities in higher cortical sensory perception. Using a meta-analysis of sensory modulation symptoms, Ben-Sasson et al. (2009) reported that 14 different studies have shown sensory differences between individuals with ASD and typically developing individuals with the greatest difference in under-responsivity, followed by over-responsivity and then sensation seeking. Researchers and clinicians have observed changes in persons who seem to react strongly to everyday sensory input, particularly individuals on the autism spectrum who generally have more frequent and intense reactions to external sensory stimuli. Some researchers and clinicians have hypothesized that a person with ASD typically has trouble processing information from the outside world because sensory problems make it difficult to understand what is being seen, heard, and touched. Although the severe reactions to various external sensory stimuli have been discussed in the literature for decades (Baranek, Wakefield, & David, 2008), a systematic process for identifying the precise sensory problems have not been identified and only a few cases of empirical evidence of effective interventions have been (Van Rie &" @default.
