Mimicry and social affiliation with virtual partner are decreased in autism / Bahar TUNCGENC in Research in Autism Spectrum Disorders, 100 (February 2023)
[article]
Titre : Mimicry and social affiliation with virtual partner are decreased in autism Type de document : Texte imprimé et/ou numérique Auteurs : Bahar TUNCGENC, Auteur ; Carolyn KOCH, Auteur ; Inge-Marie EIGSTI, Auteur ; Stewart H. MOSTOFSKY, Auteur Article en page(s) : 102073 Langues : Anglais (eng) Mots-clés : Mimicry Social affiliation Social interactions Autism Children Index. décimale : PER Périodiques Résumé : Copying other people’s mannerisms (i.e., mimicry) occurs spontaneously during social interactions, and is thought to contribute to sharing emotions, affiliation with partners and interaction quality. While previous research shows decreased mimicry of emotional facial expressions in autism spectrum disorders (ASD), we know relatively little about how non-emotional, non-facial behavioural mimicry manifests and, more importantly, what it means for autistic individuals’ social interactions. In a controlled, semi-naturalistic interaction setting, this study examined how often autistic and neurotypical (NT) children mimicked a virtual partner’s non-facial mannerisms as they engaged in an interactive story-telling activity. Subsequently, children reported how affiliated they felt towards their interaction partner using an established implicit measure of closeness and a set of questions. Results revealed reduced mimicry (p = .001, φ = 0.38) and less affiliation (p = .01, φ = 0.33) in ASD relative to NT children. Mimicry was associated with affiliation for NT (r(23) = 0.64, p = .0009), but not ASD, children (r(31) = 0.07, p = .72). These results suggest an autism-associated reduction in mimicry and that mimicry during social interactions may not substantially contribute to affiliation in autism.

Titre : Motor Circuit Anatomy in Children with Autism Spectrum Disorder With or Without Attention Deficit Hyperactivity Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Rajneesh MAHAJAN, Auteur ; Benjamin DIRLIKOV, Auteur ; Deana CROCETTI, Auteur ; Stewart H. MOSTOFSKY, Auteur Article en page(s) : p.67-81 Langues : Anglais (eng) Mots-clés : structural MRI motor circuit autism spectrum disorder attention deficit hyperactivity disorder Index. décimale : PER Périodiques Résumé : This study examined the morphology of frontal-parietal regions relevant to motor functions in children with autism spectrum disorder (ASD) with or without attention deficit hyperactivity disorder (ADHD). We also explored its associations with autism severity and motor skills, and the impact of comorbid ADHD on these associations. Participants included 126 school-age children: 30 had ASD only, 33 had ASD with ADHD, and 63 were typically developing. High resolution 3T MPRAGE images were acquired to examine the cortical morphology (gray matter volume, GMV, surface area, SA, and cortical thickness, CT) in three regions of interest (ROI): precentral gyrus (M1), postcentral gyrus (S1), and inferior parietal cortex (IPC). Children with ASD showed abnormal increases in GMV and SA in all three ROIs: (a) increased GMV in S1 bilaterally and in right M1 was specific to children with ASD without ADHD; (b) all children with ASD (with or without ADHD) showed increases in the left IPC SA. Furthermore, on measures of motor function, impaired praxis was associated with increased GMV in right S1 in the ASD group with ADHD. Children with ASD with ADHD showed a positive relationship between bilateral S1 GMV and manual dexterity, whereas children with ASD without ADHD showed a negative relationship. Our findings suggest that (a) ASD is associated with abnormal morphology of cortical circuits crucial to motor control and learning; (b) anomalous overgrowth of these regions, particularly S1, may contribute to impaired motor skill development, and (c) functional and morphological differences are apparent between children with ASD with or without ADHD.

Titre : Motor Learning Relies on Integrated Sensory Inputs in ADHD, but Over-Selectively on Proprioception in Autism Spectrum Conditions Type de document : Texte imprimé et/ou numérique Auteurs : Jun IZAWA, Auteur ; Sarah E. PEKNY, Auteur ; Mollie K. MARKO, Auteur ; Courtney C. HASWELL, Auteur ; Reza SHADMEHR, Auteur ; Stewart H. MOSTOFSKY, Auteur Année de publication : 2012 Article en page(s) : p.124-136 Langues : Anglais (eng) Mots-clés : motor learning internal model generalization Index. décimale : PER Périodiques Résumé : The brain builds an association between action and sensory feedback to predict the sensory consequence of self-generated motor commands. This internal model of action is central to our ability to adapt movements and may also play a role in our ability to learn from observing others. Recently, we reported that the spatial generalization patterns that accompany adaptation of reaching movements were distinct in children with autism spectrum disorder (ASD) as compared with typically developing (TD) children. To test whether the generalization patterns are specific to ASD, here, we compared the patterns of adaptation with those in children with attention deficit hyperactivity disorder (ADHD). Consistent with our previous observations, we found that in ASD, the motor memory showed greater than normal generalization in proprioceptive coordinates compared with both TD children and children with ADHD; children with ASD also showed slower rates of adaptation compared with both control groups. Children with ADHD did not show this excessive generalization to the proprioceptive target, but they did show excessive variability in the speed of movements with an increase in the exponential distribution of responses (τ) as compared with both TD children and children with ASD. The results suggest that slower rate of adaptation and anomalous bias towards proprioceptive feedback during motor learning are characteristics of autism, whereas increased variability in execution is a characteristic of ADHD.

Titre : No Proprioceptive Deficits in Autism Despite Movement-Related Sensory and Execution Impairments Type de document : Texte imprimé et/ou numérique Auteurs : Christina T. FUENTES, Auteur ; Stewart H. MOSTOFSKY, Auteur ; Amy J. BASTIAN, Auteur Année de publication : 2011 Langues : Anglais (eng) Mots-clés : Proprioception Motor control Sensory processing Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) often involves sensory and motor problems, yet the proprioceptive sense of limb position has not been directly assessed. We used three tasks to assess proprioception in adolescents with ASD who had motor and sensory perceptual abnormalities, and compared them to age- and IQ-matched controls. Results showed no group differences in proprioceptive accuracy or precision during active or passive tasks. Both groups showed (a) biases in elbow angle accuracy that varied with joint position, (b) improved elbow angle precision for active versus passive tasks, and (c) improved precision for a fingertip versus elbow angle estimation task. Thus, a primary proprioceptive deficit may not contribute to sensorimotor deficits in ASD. Abnormalities may arise at later sensory processing stages.
