Perceptual and Neural Response to Affective Tactile Texture Stimulation in Adults with Autism Spectrum Disorders / Carissa J. CASCIO in Autism Research, 5-4 (August 2012)
[article]
Titre : Perceptual and Neural Response to Affective Tactile Texture Stimulation in Adults with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Carissa J. CASCIO, Auteur ; Estephan J. MOANA-FILHO, Auteur ; Steve GUEST, Auteur ; Mary Beth NEBEL, Auteur ; Jonathan WEISNER, Auteur ; Grace T. BARANEK, Auteur ; Gregory ESSICK, Auteur Année de publication : 2012 Article en page(s) : p.231-44 Langues : Anglais (eng) Mots-clés : touch fMRI sensory adults psychophysics affective Index. décimale : PER Périodiques Résumé : Autism spectrum disorders (ASD) are associated with differences in sensory sensitivity and affective response to sensory stimuli, the neural basis of which is still largely unknown. We used psychophysics and functional magnetic resonance imaging (fMRI) to investigate responses to somatosensory stimulation with three textured surfaces that spanned a range of roughness and pleasantness in a sample of adults with ASD and a control group. While psychophysical ratings of roughness and pleasantness were largely similar across the two groups, the ASD group gave pleasant and unpleasant textures more extreme average ratings than did controls. In addition, their ratings for a neutral texture were more variable than controls, indicating they are less consistent in evaluating a stimulus that is affectively ambiguous. Changes in brain blood oxygenation level-dependent (BOLD) signal in response to stimulation with these textures differed substantially between the groups, with the ASD group exhibiting diminished responses compared to the control group, particularly for pleasant and neutral textures. For the most unpleasant texture, the ASD group exhibited greater BOLD response than controls in affective somatosensory processing areas such as the posterior cingulate cortex and the insula. The amplitude of response in the insula in response to the unpleasant texture was positively correlated with social impairment as measured by the Autism Diagnostic Interview-Revised (ADI-R). These results suggest that people with ASD tend to show diminished response to pleasant and neutral stimuli, and exaggerated limbic responses to unpleasant stimuli, which may contribute to diminished social reward associated with touch, perpetuating social withdrawal, and aberrant social development.

Titre : Perceptual metrics of individuals with autism provide evidence for disinhibition Type de document : Texte imprimé et/ou numérique Auteurs : Vinay TANNAN, Auteur ; Grace T. BARANEK, Auteur ; Jameson K. HOLDEN, Auteur ; Zheng ZHANG, Auteur ; Mark A. TOMMERDAHL, Auteur Année de publication : 2008 Article en page(s) : p.223-230 Langues : Anglais (eng) Mots-clés : autism inhibition adaptation habituation amplitude discrimination sensory-discrimination Index. décimale : PER Périodiques Résumé : Adults with autism exhibit inhibitory deficits that are often manifested in behavioral modifications, such as repetitive behaviors, and/or sensory hyper-responsiveness. If such behaviors are the result of a generalized deficiency in inhibitory neurotransmission, then it stands to reason that deficits involving localized cortical-cortical interactions - such as in sensory discrimination tasks - could be detected and quantified. This study exemplifies a newly developed method for quantifying sensory testing metrics. Our novel sensory discrimination tests may provide (a) an effective means for biobehavioral assessment of deficits specific to autism and (b) an efficient and sensitive measure of change following treatment. The sensory discriminative capacity of ten subjects with autism and ten controls was compared both before and after short duration adapting stimuli. Specifically, vibrotactile amplitude discriminative capacity was obtained both in the presence and absence of 1 sec adapting stimuli that were delivered 1 sec prior to the comparison stimuli. Although adaptation had a pronounced effect on the amplitude discriminative capacity of the control subjects, little or no impact was observed on the sensory discriminative capacity of the subjects with autism. This lack of impact of the adapting stimuli on the responses of the subjects with autism was interpreted to be consistent with the reduced GABAergic-mediated inhibition described in previous reports. One significant aspect of this study is that the methods could prove to be a useful and efficient way to detect specific neural deficits and monitor the efficacy of pharmacological or behavioral treatments in autism.

TURNER-BROWN, Auteur Article en page(s) : p.172-186 Langues : Anglais (eng) Mots-clés : Infants at-risk for autism spectrum disorder (ASD) Sensory reactivity patterns Social-communication Parent responsiveness Index. décimale : PER Périodiques Résumé : Parent responsiveness is critical for child development of cognition, social-communication, and self-regulation. Parents tend to respond more frequently when children at-risk for autism spectrum disorder (ASD) demonstrate stronger social-communication; however, it is unclear how responsiveness is associated with sensory characteristics of children at-risk for ASD. To address this issue, we examined the extent to which child social-communication and sensory reactivity patterns (i.e., hyper- and hypo-reactivity) predicted parent responsiveness to 1-year-olds at-risk for ASD in a community sample of 97 parent-infant pairs. A combination of child social-communication and sensory hypo-reactivity consistently predicted how parents played and talked with their 1-year-old at-risk for ASD. Parents tended to talk less and use more play actions when infants communicated less and demonstrated stronger hypo-reactivity.

BARANEK, Auteur ; Linda R. WATSON, Auteur ; Lauren M. TURNER-BROWN, Auteur ; S. H. FIELD, Auteur ; Elizabeth R. CRAIS, Auteur ; L. WAKEFORD, Auteur ; L. M. LITTLE, Auteur ; J. S. REZNICK, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study examined the (a) feasibility of enrolling 12-month-olds at risk of ASD from a community sample into a randomized controlled trial, (b) subsequent utilization of community services, and (c) potential of a novel parent-mediated intervention to improve outcomes. The First Year Inventory was used to screen and recruit 12-month-old infants at risk of ASD to compare the effects of 6-9 months of Adapted Responsive Teaching (ART) versus referral to early intervention and monitoring (REIM). Eighteen families were followed for ~20 months. Assessments were conducted before randomization, after treatment, and at 6-month follow-up. Utilization of community services was highest for the REIM group. ART significantly outperformed REIM on parent-reported and observed measures of child receptive language with good linear model fit. Multiphase growth models had better fit for more variables, showing the greatest effects in the active treatment phase, where ART outperformed REIM on parental interactive style (less directive), child sensory responsiveness (less hyporesponsive), and adaptive behavior (increased communication and socialization). This study demonstrates the promise of a parent-mediated intervention for improving developmental outcomes for infants at risk of ASD in a community sample and highlights the utility of earlier identification for access to community services earlier than standard practice.

BOYD, Auteur ; Grace T. BARANEK, Auteur ; Tia N. HOLTZCLAW, Auteur ; Matthew MCBEE, Auteur ; James W. BODFISH, Auteur Année de publication : 2009 Article en page(s) : p.959-966 Langues : Anglais (eng) Mots-clés : Autism-spectrum-disorder Repetitive-behaviors Sensory-features Executive-function Index. décimale : PER Périodiques Résumé : This study examined the relationship between repetitive behaviors and sensory processing issues in school-aged children with high functioning autism (HFA). Children with HFA (N = 61) were compared to healthy, typical controls (N = 64) to determine the relationship between these behavioral classes and to examine whether executive dysfunction explained any relationship between the variables. Particular types of repetitive behavior (i.e., stereotypy and compulsions) were related to sensory features in autism; however, executive deficits were only correlated with repetitive behavior. This finding suggests that executive dysfunction is not the shared neurocognitive mechanism that accounts for the relationship between restricted, repetitive behaviors and aberrant sensory features in HFA. Group status, younger chronological age, presence of sensory processing issues, and difficulties with behavior regulation predicted the presence of repetitive behaviors in the HFA group.
