Biological motion and the animate–inanimate distinction in children with high-functioning Autism Spectrum Disorder / Kristyn WRIGHT in Research in Autism Spectrum Disorders, 25 (May 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 25 (May 2016) . - p.1-11 Titre : Biological motion and the animate–inanimate distinction in children with high-functioning Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Kristyn WRIGHT, Auteur ; Elizabeth KELLEY, Auteur ; Diane POULIN-DUBOIS, Auteur Article en page(s) : p.1-11 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Biological motion  Social orienting  Animate–inanimate distinction Index. décimale : PER Périodiques Résumé : The current study examined whether children with high-functioning Autism Spectrum Disorder (HF-ASD) preferentially attend to point-light displays of biological, compared to mechanical motion. We hypothesized that children’s attentional patterns toward the motion of living things would be reduced compared to typically developing (TD) children. Children also completed two categorization tasks measuring the animate–inanimate distinction. Children with HF-ASD were matched with TD children (n = 18 per group) on age, gender, and verbal ability. Overall, children with HF-ASD attended to biological and non-biological motion equally, whereas TD children demonstrated a preference for inanimate motion. Children with HF-ASD were also unimpaired in the formation of animate and inanimate concepts. Among children with HF-ASD, a link between attention to motion and categorization ability was observed, but only for inanimate objects. TD and HF-ASD groups differed in that visual exploration of the motion videos (e.g., saccades) was related to animate–inanimate categorization only among children with HF-ASD. These results are discussed as a low-level test of the social attention/orienting hypothesis.

Concurrent Validity of the Modified Checklist for Autism in Toddlers (M-CHAT): Socio-cognitive and Verbal Skills in 18-Month-Old Infants / Alexa RUEL in Journal of Autism and Developmental Disorders, 51-3 (March 2021)

Previous findings have confirmed the M-CHAT's sensitivity and specificity across several cultures, yet few studies have considered M-CHAT scores as a distributed trait in a sample of typical infants. The current study examined how the M-CHAT predicts concurrent word learning (experiment 1) as well as socio-emotional understanding (experiment 2) in 18-month-old infants. Results demonstrated that the number of items endorsed on the M-CHAT negatively correlated with the proportion of trials on which infants looked at a toy named by the experimenter as well as performance on the word learning task. In experiment 2, high scores on the M-CHAT correlated with less instrumental helping, less imitation, and a smaller productive vocabulary size.

Modified Checklist for Autism in Toddlers (M-CHAT) screening at 18 months of age predicts concurrent understanding of desires, word learning and expressive vocabulary / Kristyn WRIGHT in Research in Autism Spectrum Disorders, 6-1 (January-March 2012)

The current studies examine the concurrent validity of the M-CHAT in its ability to predict 18-month-olds’ performance on theory of mind and word learning tasks. In Experiment 1, infants’ understanding of desires was tested using a modified food request task. Experiment 2 assessed infants’ ability to learn novel words. Results indicate that infants’ score on the M-CHAT significantly predicts their performance on both the desire understanding and the novel word learning task. As expected, the number of items endorsed on the M-CHAT also relates to infants’ expressive vocabulary at 18 months of age. Taken together, these findings confirm the concurrent validity of the M-CHAT at the youngest age this measure can reliably be administered. Within a broader clinical context, the present results provide preliminary evidence that controlled laboratory tasks assessing early social cognitive and verbal abilities could be added to the battery of screening instruments for ASD.

Naïve Theories of Biology, Physics, and Psychology in Children with ASD / Diane POULIN-DUBOIS in Journal of Autism and Developmental Disorders, 51-10 (October 2021)

It develops around the age of 4 but seems to remain deficient in people with ASD, whereas other forms of naïve understanding remain intact. This study compares children with ASD to neurotypical children on tasks measuring naïve psychology, physics, and biology (biological parts). Results suggest that children with ASD only underperform on an implicit false belief task. Performances in naïve biology and physics were equivalent across the two groups and uncorrelated to performance on the false belief task. This confirms that naïve physics and biological reasoning are intact in children with ASD but that tracking false beliefs is challenging for this population.

Schematic and realistic biological motion identification in children with high-functioning Autism Spectrum Disorder / Kristyn WRIGHT in Research in Autism Spectrum Disorders, 8-10 (October 2014)

The current study investigated how children with high-functioning ASD (HF-ASD) performed on two tasks of biological motion identification: a novel schematic motion identification task and a point-light biological motion identification task. Twenty-two HF-ASD children were matched with 21 TD children on gender, non-verbal mental, and chronological, age (M years = 6.72). On both tasks, HF-ASD children performed with similar accuracy as TD children. Across groups, children performed better on animate than on inanimate trials of both tasks. These findings suggest that identification of both realistic and schematic biological motion is unimpaired in children with HF-ASD.
