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 et/ou numérique 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.

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.

Social motivation and implicit theory of mind in children with autism spectrum disorder / Kimberly BURNSIDE in Autism Research, 10-11 (November 2017)  

Public ISBD [article]  inAutism Research > 10-11 (November 2017) . - p.1834-1844 Titre : Social motivation and implicit theory of mind in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Kimberly BURNSIDE, Auteur ; Kristyn WRIGHT, Auteur ; Diane POULIN-DUBOIS, Auteur Article en page(s) : p.1834-1844 Langues : Anglais (eng) Mots-clés : autism  social motivation  social orienting  theory of mind Index. décimale : PER Périodiques Résumé : According to the social motivation theory of autism, children who develop Autism Spectrum Disorder (ASD) have early deficits in social motivation, which is expressed by decreased attention to social information. These deficits are said to lead to impaired socio-cognitive development, such as theory of mind (ToM). There is little research focused on the relation between social motivation and ToM in this population. The goal of the present study was to investigate the link between one aspect of social motivation, social orienting, and ToM in preschoolers with ASD. It was expected that, in contrast to typically developing (TD) children, children with ASD would show impaired performance on tasks measuring social orienting and ToM. It was also expected that children's performance on the social orienting tasks would be correlated with their performance on the ToM task. A total of 17 children with ASD and 16 TD children participated in this study. Participants completed two social orienting tasks, a face preference task and a biological motion preference task, as well an implicit false belief task. Results reveal that TD children, but not children with ASD, exhibited social preference as measured by a preference for faces and biological motion. Furthermore, children with ASD tended to perform worse on the ToM task compared to their TD counterparts. Performance on the social motivation tasks and the ToM task tended to be related but only for the TD children. These findings suggest that ToM is multifaceted and that motivational deficits might have downstream effects even on implicit ToM. Autism Res 2017, 10: 1834–1844. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary The goal of the present study was to examine the link between poor attention to social information and mindreading abilities in children with autism spectrum disorder (ASD). Results demonstrated that children with ASD tended to perform worse than neurotypical children on both social orienting and theory of mind tasks. Preference for human faces and motion tended to be related but only for the neurotypical children. These findings provide partial support for the social motivation theory.
