Neural Correlates of Set-Shifting in Children With Autism / Benjamin E. YERYS in Autism Research, 8-4 (August 2015)
[article]
Titre : Neural Correlates of Set-Shifting in Children With Autism Type de document : Texte imprimé et/ou numérique Auteurs : Benjamin E. YERYS, Auteur ; Ligia ANTEZANA, Auteur ; Rachel WEINBLATT, Auteur ; Kathryn F. JANKOWSKI, Auteur ; John STRANG, Auteur ; Chandan J. VAIDYA, Auteur ; Robert T. SCHULTZ, Auteur ; William D. GAILLARD, Auteur ; Lauren KENWORTHY, Auteur Article en page(s) : p.386-397 Langues : Anglais (eng) Mots-clés : autism cognitive control set-shifting functional magnetic resonance imaging cingulate prefrontal cortex Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is often associated with high levels of inflexible thinking and rigid behavior. The neural correlates of these behaviors have been investigated in adults and older adolescents, but not children. Prior studies utilized set-shifting tasks that engaged multiple levels of shifting, and depended on learning abstract rules and establishing a strong prepotent bias. These additional demands complicate simple interpretations of the results. We used functional magnetic resonance imaging (fMRI) to investigate the neural correlates of set-shifting in 20 children (ages 7–14) with ASD and 19 typically developing, matched, control children. Participants completed a set-shifting task that minimized nonshifting task demands through the use of concrete instructions that provide spatial mapping of stimuli-responses. The shift/stay sets were given an equal number of trials to limit the prepotent bias. Both groups showed an equivalent “switch cost,” responding less accurately and slower to Switch stimuli than Stay stimuli, although the ASD group was less accurate overall. Both groups showed activation in prefrontal, striatal, parietal, and cerebellum regions known to govern effective set-shifts. Compared to controls, children with ASD demonstrated decreased activation of the right middle temporal gyrus across all trials, but increased activation in the mid-dorsal cingulate cortex/superior frontal gyrus, left middle frontal, and right inferior frontal gyri during the Switch vs. Stay contrast. The successful behavioral switching performance of children with ASD comes at the cost of requiring greater engagement of frontal regions, suggesting less efficiency at this lowest level of shifting.

ASD participants were a clinically referred sample of preschoolers; the typically developing control group was selected from the BRIEF-P standardization sample. The ASD group was rated significantly worse on all BRIEF-P scores, and these impairments did not correlate with ASD symptoms. These findings document impairments in real world EC in preschoolers with ASD, and have implications for assessing preschoolers suspected of having an ASD. Furthermore, the findings also converge with BRIEF studies of school-aged children with ASD.

This new algorithm, however, has not yet been validated in an independent sample without intellectual disability (ID). This multi-site study compared the original and revised algorithms in individuals with ASD without ID. The revised algorithm demonstrated increased sensitivity, but lower specificity in the overall sample. Estimates were highest for females, individuals with a verbal IQ below 85 or above 115, and ages 16 and older. Best practice diagnostic procedures should include the Module 4 in conjunction with other assessment tools. Balancing needs for sensitivity and specificity depending on the purpose of assessment (e.g., clinical vs. research) and demographic characteristics mentioned above will enhance its utility.

KENWORTHY, Auteur Année de publication : 2009 Article en page(s) : p.523-538 Langues : Anglais (eng) Mots-clés : attention autism ID/ED-shift-task set-shifting Index. décimale : PER Périodiques Résumé : Research examining set-shifting has revealed significant difficulties for adults with autism spectrum disorders (ASDs). However, research with high-functioning children with ASDs has yielded mixed results. The current study tested 6- to 13-year-old high-functioning children with ASD and typically developing controls matched on age, gender, and IQ using the Intradimensional/Extradimensional (ID/ED) Shift Test from the Cambridge Neuropsychological Test Automated Battery. Children with ASDs completed as many ED shifts and reversal ED shifts as controls; however, they made significantly more errors than controls while completing the ED reversal shifts. Analyses on a subset of cases revealed a significant positive correlation between ED reversal errors and the number of repetitive behavior symptoms in the ASD group. These findings suggest that high-functioning children with ASDs require additional feedback to shift successfully. In addition, the relationship between set-shifting and non-social symptoms suggests its utility as a potentially informative intermediate phenotype in ASDs.

Titre : Social-Emotional Inhibition of Return in Children with Autism Spectrum Disorder Versus Typical Development Type de document : Texte imprimé et/ou numérique Auteurs : Ligia ANTEZANA, Auteur ; Maya G. MOSNER, Auteur ; Vanessa TROIANI, Auteur ; Benjamin E. YERYS, Auteur Année de publication : 2016 Article en page(s) : p.1236-1246 Langues : Anglais (eng) Mots-clés : Visual attention Orienting Inhibition of return Children Autism spectrum disorder Comorbidities Index. décimale : PER Périodiques Résumé : In typical development there is a bias to orient visual attention to social information. Children with ASD do not reliably demonstrate this bias, and the role of attention orienting has not been well studied. We examined attention orienting via the inhibition of return (IOR) mechanism in a spatial cueing task using social-emotional cues; we studied 8- to 17-year-old children with ASD (n = 41) and typically developing controls (TDC) (n = 25). The ASD group exhibited a significantly stronger IOR effect than the TDC group, and the IOR effect correlated positively with social impairments but was unrelated to co-occurring ADHD or anxiety symptoms. The results provide evidence of an early altered attention mechanism that is associated with to core social deficits in ASD.
