Children with Autism Detect Targets at Very Rapid Presentation Rates with Similar Accuracy as Adults / Carl Erick HAGMANN in Journal of Autism and Developmental Disorders, 46-5 (May 2016)
[article]
Titre : Children with Autism Detect Targets at Very Rapid Presentation Rates with Similar Accuracy as Adults Type de document : Texte imprimé et/ou numérique Auteurs : Carl Erick HAGMANN, Auteur ; Bradley WYBLE, Auteur ; Nicole SHEA, Auteur ; Megan LEBLANC, Auteur ; Wendy R. KATES, Auteur ; Natalie RUSSO, Auteur Article en page(s) : p.1762-1772 Langues : Anglais (eng) Mots-clés : Autism RSVP Visual search Attention Perception Cognition Development Index. décimale : PER Périodiques Résumé : Enhanced perception may allow for visual search superiority by individuals with Autism Spectrum Disorder (ASD), but does it occur over time? We tested high-functioning children with ASD, typically developing (TD) children, and TD adults in two tasks at three presentation rates (50, 83.3, and 116.7 ms/item) using rapid serial visual presentation. In the Color task, participants detected a purple target letter amongst black letter distractors. In the Category task, participants detected a letter amongst number distractors. Slower rates resulted in higher accuracy. Children with ASD were more accurate than TD children and similar to adults at the fastest rate when detecting color-marked targets, indicating atypical neurodevelopment in ASD may cause generalized perceptual enhancement relative to typically developing peers.

Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BACKGROUND: Differences in responding to sensory stimuli, including sensory hyperreactivity (HYPER), hyporeactivity (HYPO), and sensory seeking (SEEK) have been observed in autistic individuals across sensory modalities, but few studies have examined the structure of these "supra-modal" traits in the autistic population. METHODS: Leveraging a combined sample of 3868 autistic youth drawn from 12 distinct data sources (ages 3-18 years and representing the full range of cognitive ability), the current study used modern psychometric and meta-analytic techniques to interrogate the latent structure and correlates of caregiver-reported HYPER, HYPO, and SEEK within and across sensory modalities. Bifactor statistical indices were used to both evaluate the strength of a "general response pattern" factor for each supra-modal construct and determine the added value of "modality-specific response pattern" scores (e.g., Visual HYPER). Bayesian random-effects integrative data analysis models were used to examine the clinical and demographic correlates of all interpretable HYPER, HYPO, and SEEK (sub)constructs. RESULTS: All modality-specific HYPER subconstructs could be reliably and validly measured, whereas certain modality-specific HYPO and SEEK subconstructs were psychometrically inadequate when measured using existing items. Bifactor analyses supported the validity of a supra-modal HYPER construct (?(H)=.800) but not a supra-modal HYPO construct (?(H)=.653), and supra-modal SEEK models suggested a more limited version of the construct that excluded some sensory modalities (?(H)=.800; 4/7 modalities). Modality-specific subscales demonstrated significant added value for all response patterns. Meta-analytic correlations varied by construct, although sensory features tended to correlate most with other domains of core autism features and co-occurring psychiatric symptoms (with general HYPER and speech HYPO demonstrating the largest numbers of practically significant correlations). LIMITATIONS: Conclusions may not be generalizable beyond the specific pool of items used in the current study, which was limited to caregiver report of observable behaviors and excluded multisensory items that reflect many "real-world" sensory experiences. CONCLUSION: Of the three sensory response patterns, only HYPER demonstrated sufficient evidence for valid interpretation at the supra-modal level, whereas supra-modal HYPO/SEEK constructs demonstrated substantial psychometric limitations. For clinicians and researchers seeking to characterize sensory reactivity in autism, modality-specific response pattern scores may represent viable alternatives that overcome many of these limitations.

Titre : Examining the Temporal Limits of Enhanced Visual Feature Detection in Children With Autism Type de document : Texte imprimé et/ou numérique Auteurs : Justin KOPEC, Auteur ; Carl Erick HAGMANN, Auteur ; Nicole SHEA, Auteur ; Alyssa PRAWL, Auteur ; Daniel BATKIN, Auteur ; Natalie RUSSO, Auteur Article en page(s) : p.1561-1572 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The enhanced perceptual processing of visual features in children with autism spectrum disorder (ASD) is supported by an abundance of evidence in the spatial domain, with less robust evidence regarding whether this extends to information presented across time. The current study aimed to replicate and extend previous work finding that children with an ASD demonstrated enhanced perceptual accuracy in detecting feature-based (but not categorically defined) targets in time, when these were presented quickly, at a stimulus onset asynchrony (SOA) of 50?ms per item. Specifically, we extend the range of SOAs to examine the temporal boundaries of this enhanced accuracy and examine whether there is a relationship between ASD-related traits and detection accuracy on temporal visual search tasks. Individuals with autism perceived feature-based targets with statistically higher accuracy than their typically developing peers between SOAs of 39 and 65?ms and were numerically faster at all SOAs. No group differences were noted for category-based task accuracy. Our results also demonstrated that ASD-related traits measured by the autism spectrum quotient were positively correlated with accuracy on the feature-based task. Overall, results suggest that accurate visual perception of features (particularly color) is enhanced in children with ASD across time. Lay Summary Our results suggest that children with autism are able to process visual features, such as color, more accurately than typically developing children, even when these are presented very rapidly. Accuracy was higher in children with higher levels of autism-related traits and symptoms. Our findings suggest that more accurate visual perception exists not only across space in children with autism, as much of the existing literature demonstrates, but also over time.

HICKS, Auteur Article en page(s) : 101788 Langues : Anglais (eng) Mots-clés : Prognosis Biomarkers Saliva RNA microRNA Autism Index. décimale : PER Périodiques Résumé : Background Autism spectrum disorder (ASD) is a complex neurological condition with increasing prevalence. Few tools accurately predict the developmental trajectory of children with ASD. Such tools would allow clinicians to provide accurate prognoses and track the efficacy of therapeutic interventions. Salivary RNAs that reflect the genetic-environmental interactions underlying ASD may provide objective measures of symptom severity and developmental outcomes. This study investigated whether salivary RNAs previously identified in childhood ASD remain perturbed in older children. We also explored whether RNA candidates changed with therapeutic intervention. Method A case-control design was used to characterize levels of 78 saliva RNA candidates among 96 children (48 ASD, 48 non-ASD, mean age: 11 years). Thirty-one children (22 ASD, 9 non-ASD developmental delay, mean age: 4 years) were followed longitudinally to explore changes of RNA candidates during early intervention. Saliva RNA and standardized behavioral assessments were collected for each participant. Associations between candidate RNAs and behavioral scores were determined in both groups via Spearman Correlation. Changes in candidate RNAs across two time-points were assessed in the younger cohort via Wilcoxon rank-sum test. Results Seven RNAs were associated with VABS-II and BASC scores in the older group ([R] >0.25, FDR?0.15). Within the younger cohort, 12 RNAs displayed significant changes over time (FDR?0.05). Three microRNAs were associated with behavioral scores and changed over time (miR-182?5p, miR-146b-5p, miR-374a-5p). Conclusion Several salivary RNAs are strongly associated with autistic behaviors in older individuals with ASD and change as early as three months after therapy initiation in younger children. These molecules could be used to track treatment effectiveness and provide prognoses. Further validation is necessary.
