Hyporesponsiveness to social and nonsocial sensory stimuli in children with autism, children with developmental delays, and typically developing children / Grace T. BARANEK in Development and Psychopathology, 25-2 (May 2013)  

Public ISBD [article]  inDevelopment and Psychopathology > 25-2 (May 2013) . - p.307-320 Titre : Hyporesponsiveness to social and nonsocial sensory stimuli in children with autism, children with developmental delays, and typically developing children Type de document : texte imprimé Auteurs : Grace T. BARANEK, Auteur ; Linda R. WATSON, Auteur ; Brian A. BOYD, Auteur ; Michele D. POE, Auteur ; Fabian J. DAVID, Auteur ; Lorin MCGUIRE, Auteur Article en page(s) : p.307-320 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This cross-sectional study seeks to (a) describe developmental correlates of sensory hyporesponsiveness to social and nonsocial stimuli, (b) determine whether hyporesponsiveness is generalized across contexts in children with autism relative to controls, and (c) test the associations between hyporesponsiveness and social communication outcomes. Three groups of children ages 11–105 months (N = 178; autism = 63, developmental delay = 47, typical development = 68) are given developmental and sensory measures including a behavioral orienting task (the Sensory Processing Assessment). Lab measures are significantly correlated with parental reports of sensory hyporesponsiveness. Censored regression models show that hyporesponsiveness decreased across groups with increasing mental age (MA). Group differences are significant but depend upon two-way interactions with MA and context (social and nonsocial). At a very young MA (e.g., 6 months), the autism group demonstrates more hyporesponsiveness to social and nonsocial stimuli (with larger effects for social) than developmental delay and typically developing groups, but at an older MA (e.g., 60 months) there are no significant differences. Hyporesponsiveness to social and nonsocial stimuli predicts lower levels of joint attention and language in children with autism. Generalized processes in attention disengagement and behavioral orienting may have relevance for identifying early risk factors of autism and for facilitating learning across contexts to support the development of joint attention and language.

Method: Caregivers of 258 children in five diagnostic groups (Autism, PDD, DD/MR, Other DD, Typical) ages 5–80 months completed the SEQ. Results: The SEQ's internal consistency was α' = .80. Prevalence of overall sensory symptoms for the Autism group was 69%. Sensory symptoms were inversely related to mental age. The Autism group had significantly higher symptoms than either the Typical or DD groups and presented with a unique pattern of response to sensory stimuli –hyporesponsiveness in both social and nonsocial contexts. A pattern of hyperresponsiveness was similar in the Autism and DD groups, but significantly greater in both clinical groups than in the Typical group. Conclusion: The SEQ was able to characterize sensory features in young children with autism, and differentiate their sensory patterns from comparison groups. These unique sensory patterns have etiological implications, as well as relevance for assessment and intervention practices.

Sensory features and repetitive behaviors in children with autism and developmental delays / Brian A. BOYD in Autism Research, 3-2 (April 2010)

Confirmatory factor analysis was used to empirically validate three sensory constructs of interest: hyperresponsiveness, hyporesponsiveness, and sensory seeking. Examining the association between the three derived sensory factor scores and scores on the Repetitive Behavior Scales - Revised revealed the co-occurrence of these behaviors in both clinical groups. Specifically, high levels of hyperresponsive behaviors predicted high levels of repetitive behaviors, and the relationship between these variables remained the same controlling for mental age. We primarily found non-significant associations between hyporesponsiveness or sensory seeking and repetitive behaviors, with the exception that sensory seeking was associated with ritualistic/sameness behaviors. These findings suggest that shared neurobiological mechanisms may underlie hyperresponsive sensory symptoms and repetitive behaviors and have implications for diagnostic classification as well as intervention.

Teasing apart the heterogeneity of autism: Same behavior, different brains in toddlers with fragile X syndrome and autism / Heather C. HAZLETT in Journal of Neurodevelopmental Disorders, 1-1 (March 2009)

A cross-sectional study of brain substructures was conducted at the first time-point as part of an ongoing longitudinal MRI study of brain development in FXS. The study included 52 boys between 18-42 months of age with FXS and 118 comparison children (boys with autism-non FXS, developmental-delay, and typical development). Children with FXS and autistic disorder had substantially enlarged caudate volume and smaller amygdala volume; whereas those children with autistic disorder without FXS (i.e., idiopathic autism) had only modest enlargement in their caudate nucleus volumes but more robust enlargement of their amygdala volumes. Although we observed this double dissociation among selected brain volumes, no significant differences in severity of autistic behavior between these groups were observed. This study offers a unique examination of early brain development in two disorders, FXS and idiopathic autism, with overlapping behavioral features, but two distinct patterns of brain morphology. We observed that despite almost a third of our FXS sample meeting criteria for autism, the profile of brain volume differences for children with FXS and autism differed from those with idiopathic autism. These findings underscore the importance of addressing heterogeneity in studies of autistic behavior.

Temperament and Sensory Features of Children with Autism / M. BROCK in Journal of Autism and Developmental Disorders, 42-11 (November 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-11 (November 2012) . - p.2271-2284 Titre : Temperament and Sensory Features of Children with Autism Type de document : texte imprimé Auteurs : M. BROCK, Auteur ; Ashley C. FREULER, Auteur ; Grace T. BARANEK, Auteur ; Linda R. WATSON, Auteur ; Michele D. POE, Auteur ; Antoinette SABATINO-DICRISCIO, Auteur Article en page(s) : p.2271-2284 Langues : Anglais (eng) Mots-clés : Autism  Developmental delay  Temperament  Sensory processing and reactivity Index. décimale : PER Périodiques Résumé : This study sought to characterize temperament traits in a sample of children with autism spectrum disorder (ASD), ages 3–7 years old, and to determine the potential association between temperament and sensory features in ASD. Individual differences in sensory processing may form the basis for aspects of temperament and personality, and aberrations in sensory processing may inform why some temperamental traits are characteristic of specific clinical populations. Nine dimensions of temperament from the Behavioral Style Questionnaire (McDevitt and Carey in Manual for the behavioral style questionnaire, Behavioral-Developmental Initiatives, Scottsdale, AZ, 1996 ) were compared among groups of children with ASD ( n = 54), developmentally delayed (DD; n = 33), and the original normative sample of typically developing children (McDevitt and Carey in J Child Psychol Psychiatr 19(3):245–253, 1978 ; n = 350) using an ANOVA to determine the extent to which groups differed in their temperament profiles. The hypothesized overlap between three sensory constructs (hyperresponsiveness, hyporesponsivness, and seeking) and the nine dimensions of temperament was analyzed in children with ASD using regression analyses. The ASD group displayed temperament scores distinct from norms for typically developing children on most dimensions of temperament (activity, rhythmicity, adaptability, approach, distractibility, intensity, persistence, and threshold) but differed from the DD group on only two dimensions (approach and distractibility). Analyses of associations between sensory constructs and temperament dimensions found that sensory hyporesponsiveness was associated with slowness to adapt , low reactivity, and low distractibility; a combination of increased sensory features (across all three patterns) was associated with increased withdrawal and more negative mood. Although most dimensions of temperament distinguished children with ASD as a group, not all dimensions appear equally associated with sensory response patterns. Shared mechanisms underlying sensory responsiveness, temperament, and social withdrawal may be fruitful to explore in future studies.
