Brief Report: Differences in Naturalistic Attention to Real-World Scenes in Adolescents with 16p.11.2 Deletion / Amanda J. HASKINS in Journal of Autism and Developmental Disorders, 54-3 (March 2024)
[article]
Titre : Brief Report: Differences in Naturalistic Attention to Real-World Scenes in Adolescents with 16p.11.2 Deletion Type de document : Texte imprimé et/ou numérique Auteurs : Amanda J. HASKINS, Auteur ; Jeff MENTCH, Auteur ; Caitlin VAN WICKLIN, Auteur ; Yeo Bi CHOI, Auteur ; Caroline E. ROBERTSON, Auteur Article en page(s) : p.1078-1087 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Sensory differences are nearly universal in autism, but their genetic origins are poorly understood. Here, we tested how individuals with an autism-linked genotype, 16p.11.2 deletion ("16p"), attend to visual information in immersive, real-world photospheres. We monitored participants' (N = 44) gaze while they actively explored 360° scenes via headmounted virtual reality. We modeled the visually salient and semantically meaningful information in scenes and quantified the relative bottom-up vs. top-down influences on attentional deployment. We found, when compared to typically developed control (TD) participants, 16p participants' attention was less dominantly predicted by semantically meaningful scene regions, relative to visually salient regions. These results suggest that a reduction in top-down relative to bottom-up attention characterizes how individuals with 16p.11.2 deletions engage with naturalistic visual environments.

The calibrated severity score (CSS) of the Autism Diagnostic Observation Schedule-2 (ADOS-2; Lord et al., 2012) was created to better describe autism symptom severity consistently across different ages and language levels. The CSS has been widely used to quantify and compare symptom severity on a 10-point scale across Modules; however, its test re-test reliability has not been studied. With 608 ADOS observations, we showed strong test re-test reliability of the CSS across all ADOS Modules. The results support the use of the ADOS CSS as a reliable tool to quantify autism symptom severity across development.

In this study, we employed traditional electrophysiological and advanced time-frequency methods, combined with principal component analyses, to extract neural activity related to error monitoring and tested their relations to academic achievement in cognitively able kindergarteners with autism spectrum disorder. In total, 35 cognitively able kindergarteners with autism spectrum disorder completed academic assessments and the child-friendly "Zoo Game" Go/No-go task at school entry. The Go/No-go task successfully elicited an error-related negativity and error positivity in children with autism spectrum disorder as young as 5 years at fronto-central and posterior electrode sites, respectively. We also observed increased response-related theta power during errors relative to correct trials at fronto-central sites. Both larger error positivity and theta power significantly predicted concurrent academic achievement after controlling for behavioral performance on the Zoo Game and intelligence quotient. These results suggest that the use of time-frequency electroencephalography analyses, combined with traditional event-related potential measures, may provide new opportunities to investigate neurobiological mechanisms of executive function and academic achievement in young children with autism spectrum disorder.

The MONSI-CC was applied to 119 observations of 43 caregiver-child dyads of preschoolers with autism spectrum disorders (ASD). The MONSI-CC showed high inter-rater and test-retest reliability and captured significant improvements in caregivers' implementation of NDBI strategies. Significant associations between improvements in caregiver NDBI implementation and improvements in the child's ASD symptoms also emerged. Our work shows promising evidence for the utility of the MONSI-CC to evaluate implementation of NDBI strategies by caregivers as a mediating and moderating factor for treatment effects on children with ASD.

Titre : Visual processing in genetic conditions linked to autism: A behavioral study of binocular rivalry in individuals with 16p11.2 deletions and age-matched controls Type de document : Texte imprimé et/ou numérique Auteurs : Yeo Bi CHOI, Auteur ; Jeff MENTCH, Auteur ; A. J. HASKINS, Auteur ; Caitlin VAN WICKLIN, Auteur ; Caroline E. ROBERTSON, Auteur Article en page(s) : p.831-840 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Close phenotypic characterization of individuals with genetic conditions linked to autism provides a promising approach to navigating the heterogeneity of autism spectrum conditions. The current study investigated sensory processing in individuals with a rare genetic event that is highly penetrant for autism, 16p11.2 deletions, using a well-characterized visual paradigm, binocular rivalry, which is thought to be a non-invasive index of excitatory/inhibitory balance in the visual cortex. We characterized rivalry dynamics in 45 adolescent and adult individuals (19 individuals with 16p11.2 deletions, 26 age-matched neurotypical controls). We found that binocular rivalry perceptual transition rates were significantly slower for individuals with 16p11.2 deletions, relative to controls. Importantly, these results could not be accounted for by differences in motor response latencies or perceptual decision criteria, which were matched between groups. Results should be interpreted with caution given the unmatched psychometric features between groups, such as IQ. Future studies should study visual processing in other genetic groups linked to autism beyond 16p to understand the specificity of these findings. These results highlight the importance of characterizing sensory functions in individuals with genetic alterations associated with autism.
