Largely Typical Electrophysiological Affective Responses to Special Interest Stimuli in Adolescents with Autism Spectrum Disorder / K. RIVARD in Journal of Autism and Developmental Disorders, 48-9 (September 2018)

Titre : Largely Typical Electrophysiological Affective Responses to Special Interest Stimuli in Adolescents with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : K. RIVARD, Auteur ; A. B. PROTZNER, Auteur ; F. BURLES, Auteur ; M. SCHUETZE, Auteur ; I. CHO, Auteur ; K. TEN EYCKE, Auteur ; A. MCCRIMMON, Auteur ; D. DEWEY, Auteur ; F. CORTESE, Auteur ; S. BRAY, Auteur Article en page(s) : p.3133-3143 Langues : Anglais (eng) Mots-clés : Affective Autism spectrum disorder Circumscribed interests Eeg Lpp Index. décimale : PER Périodiques Résumé : Circumscribed interests are a symptom of autism spectrum disorder (ASD) that may be related to exaggerated affective neural responses. However, the use of generic ASD-interest image stimuli has left an open question as to whether affective responses towards individual interests are greater in ASD compared to typically developing (TD) controls. We compared amplitudes of the late positive potential (LPP), an affective electroencephalographic response, between adolescents with ASD (N = 19) and TD adolescents (N = 20), using images tailored to individual likes and dislikes. We found an LPP response for liked and disliked images, relative to neutral, with no difference in amplitude between groups. This suggests that the LPP is not atypical in adolescents with ASD towards images of individual interests.

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.

Play skills are related to processes of adaptive functioning and emotion understanding. The present pilot study implemented an in-person pretend play intervention to school-aged children (ages 6 to 9 years, intervention group?=?18, control group?=?7) diagnosed with high-functioning ASD (HF-ASD), to increase children's cognitive and affective play skills, and emotional understanding abilities. The intervention consisted of 5 weekly sessions, 15-20 minutes each. The intervention group significantly increased in imagination and cognitive play skills, which generalized to increased skills in emotional understanding. Findings demonstrate the positive impact of a short, easily facilitated, accessible play intervention for school-aged children with HF-ASD.

Thus, this study aims to investigate differences in mentalizing with particular interest on the socio-cognitive and socio-affective dimensions. Three Advanced Theory of Mind (ToM) tests were applied in 35 patients with HFA, 30 patients with SSPD and 36 healthy controls. Individuals with HFA showed greater impairment and no dissociation between affective and cognitive ToM components. Conversely, SSPD individuals displayed less difficulties but greater impairments on the cognitive component. Beyond the replicability of ToM impairment in HFA individuals, our findings suggest more impaired cognitive ToM in SSPD participants which further support the sequence of mentalizing development build upon different chronological stages.

Variations in tactile defensiveness with the properties of the stimulus and the bodily site of stimulation have been addressed in adults with self-report of perceived tactile pleasantness, but not in children. We presented three materials (pleasant, unpleasant, social) at three bodily sites and measured both examiner-coded defensiveness and self-reported pleasantness from a group of children with ASD and two comparison groups (one with DD, one with typical development (TD)). The main findings were: (1) children with ASD and DD showed significantly more defensiveness reactions and lower pleasantness ratings than the TD group, with higher variability, (2) there was a double dissociation for the effects of material and bodily site of stimulation: while bodily site predicted behavioral defensiveness, material predicted pleasantness rating. Additionally, it was noted that (3) the most pleasant material and the social touch conditions best distinguished ASD and DD from TD on defensiveness, and (4) within the ASD group, social impairment and defensiveness in bodily sites associated with social touch were positively correlated, suggesting a clinically relevant distinction between social and discriminative touch in ASD.
