Restricted and Repetitive Behaviours, Sensory Processing and Cognitive Style in Children with Autism Spectrum Disorders

Abstract

Many individuals with autism tend to focus on details. It has been suggested that this cognitive style may underlie the presence of stereotyped routines, repetitive interests and behaviours, and both relate in some way to sensory abnormalities. Twenty-nine children with diagnosis of high functioning autism or Asperger syndrome completed the Embedded Figures Test (EFT), and their parents the Short Sensory Profile and Childhood Routines Inventory. Significant correlations were found between degree of sensory abnormalities and amount of restricted and repetitive behaviours reported. Repetitive behaviours, age and IQ significantly predicted completion time on the EFT. The results suggest a cognitive link between an individual's detail-focused cognitive style and their repetitiveness. No such relationship was found with sensory processing abnormalities, which may arise at a more peripheral level of functioning.

Exploring the ‘fractionation’ of autism at the cognitive level

“…However, as detailed below, studies that have investigated the association between a detailed-processing style and the symptoms of ASD have produced mixed results. Chen et al (2009) found a link between a detail-focused processing style in the visual domain and degree of repetitive behaviour in children with ASD. However, there was no relation between detail-focused processing and sensory processing abnormalities.…”

Social conformity and autism spectrum disorder: A child-friendly take on a classic study

“…Situational familiarity is particularly important when collecting data with people on the autism spectrum (Chen et al, 2009). Only the participant and the researcher were present.…”

Brief Report: Exploring the Relationship Between Sensory Processing and Repetitive Behaviours in Williams Syndrome

“…It has been suggested that children with ASD who experience sensory processing abnormalities may also experience more repetitive behaviours (e.g. Chen, Rodgers, & McConachie, 2009;Baker et al, 2008). Repetitive behaviours may be functional in regulating arousal levels for children with ASD who experience sensory processing abnormalities (e.g.…”
