Brief Report: Early Lexical Comprehension in Young Children with ASD: Comparing Eye-Gaze Methodology and Parent Report / Courtney E. VENKER in Journal of Autism and Developmental Disorders, 46-6 (June 2016)

We compared parent report to an eye-gaze measure of lexical comprehension in which participants observed pairs of images on a screen, along with accompanying speech that named one of the two images. Twenty-two toddlers with ASD participated. Trials were included if the target word was reported as unknown. Children spent significantly more time looking at the target after it was named than before (d = 0.66). These results provide evidence that eye-gaze measures can reveal emerging lexical knowledge in young children with ASD that may otherwise be overlooked.

Comparing Automatic Eye Tracking and Manual Gaze Coding Methods in Young Children with Autism Spectrum Disorder / Courtney E. VENKER in Autism Research, 13-2 (February 2020)  

Public ISBD [article]  inAutism Research > 13-2 (February 2020) . - p.271-283 Titre : Comparing Automatic Eye Tracking and Manual Gaze Coding Methods in Young Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Courtney E. VENKER, Auteur ; Ron POMPER, Auteur ; Tristan MAHR, Auteur ; Jan EDWARDS, Auteur ; Jenny SAFFRAN, Auteur ; Susan ELLIS WEISMER, Auteur Article en page(s) : p.271-283 Langues : Anglais (eng) Mots-clés : autism  children  data quality  eye tracking  language processing  methodology Index. décimale : PER Périodiques Résumé : Eye-gaze methods offer numerous advantages for studying cognitive processes in children with autism spectrum disorder (ASD), but data loss may threaten the validity and generalizability of results. Some eye-gaze systems may be more vulnerable to data loss than others, but to our knowledge, this issue has not been empirically investigated. In the current study, we asked whether automatic eye-tracking and manual gaze coding produce different rates of data loss or different results in a group of 51 toddlers with ASD. Data from both systems were gathered (from the same children) simultaneously, during the same experimental sessions. As predicted, manual gaze coding produced significantly less data loss than automatic eye tracking, as indicated by the number of usable trials and the proportion of looks to the images per trial. In addition, automatic eye-tracking and manual gaze coding produced different patterns of results, suggesting that the eye-gaze system used to address a particular research question could alter a study's findings and the scientific conclusions that follow. It is our hope that the information from this and future methodological studies will help researchers to select the eye-gaze measurement system that best fits their research questions and target population, as well as help consumers of autism research to interpret the findings from studies that utilize eye-gaze methods with children with ASD. Autism Res 2020, 13: 271-283. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The current study found that automatic eye-tracking and manual gaze coding produced different rates of data loss and different overall patterns of results in young children with ASD. These findings show that the choice of eye-gaze system may impact the findings of a study-important information for both researchers and consumers of autism research.

Lexical Processing in Toddlers with ASD: Does Weak Central Coherence Play a Role? / Susan ELLIS WEISMER in Journal of Autism and Developmental Disorders, 46-12 (December 2016)

Thirty toddlers with ASD and 30 younger, cognition-matched typical controls participated in a looking-while-listening task that assessed whether perceptual or semantic similarities among named images disrupted word recognition relative to a neutral condition. Overlap of perceptual features invited local processing whereas semantic overlap invited global processing. With the possible exception of a subset of toddlers who had very low vocabulary skills, these results provide no evidence that WCC is characteristic of lexical processing in toddlers with ASD.

Predictive language processing in young autistic children / Kathryn E. PRESCOTT in Autism Research, 15-5 (May 2022)  

Public ISBD [article]  inAutism Research > 15-5 (May 2022) . - p.892-903 Titre : Predictive language processing in young autistic children Type de document : Texte imprimé et/ou numérique Auteurs : Kathryn E. PRESCOTT, Auteur ; Janine MATHÉE-SCOTT, Auteur ; Tracy REUTER, Auteur ; Jan EDWARDS, Auteur ; Jenny SAFFRAN, Auteur ; Susan ELLIS WEISMER, Auteur Article en page(s) : p.892-903 Langues : Anglais (eng) Mots-clés : Adolescent  Autism Spectrum Disorder/complications  Autistic Disorder/complications  Child  Child, Preschool  Humans  Infant  Language  Language Development Disorders/complications  Linguistics  anticipatory language processing  autism spectrum disorder  language development  prediction  receptive language Index. décimale : PER Périodiques Résumé : Recent theories propose that domain-general deficits in prediction (i.e., the ability to anticipate upcoming information) underlie the behavioral characteristics associated with autism spectrum disorder (ASD). If these theories are correct, autistic children might be expected to demonstrate difficulties on linguistic tasks that rely on predictive processing. Previous research has largely focused on older autistic children and adolescents with average language and cognition. The present study used an eye-gaze task to evaluate predictive language processing among 3- to 4-year-old autistic children (n =?34) and 1.5- to 3-year-old, language-matched neurotypical (NT) children (n =?34). Children viewed images (e.g., a cake and a ball) and heard sentences with informative verbs (e.g., Eat the cake) or neutral verbs (e.g., Find the cake). Analyses of children's looking behaviors indicated that young autistic children, like their language-matched NT peers, engaged in predictive language processing. Regression results revealed a significant effect of diagnostic group, when statistically controlling for age differences. The NT group displayed larger difference scores between the informative and neutral verb conditions (in looks to target nouns) compared to the ASD group. Receptive language measures were predictive of looking behavior across time for both groups, such that children with stronger language skills were more efficient in making use of informative verbs to process upcoming information. Taken together, these results suggest that young autistic children can engage in predictive processing though further research is warranted to explore the developmental trajectory relative to NT development. LAY SUMMARY: This study found that 3- to 4-year-old autistic children and younger, language-matched neurotypical (NT) children both used verbs to predict upcoming nouns in sentences like "Eat the cake." For both autistic and NT children, those with stronger language skills were able to predict upcoming nouns more quickly.

Use of Mutual Exclusivity and its Relationship to Language Ability in Toddlers with Autism Spectrum Disorder / Janine MATHEE-SCOTT in Journal of Autism and Developmental Disorders, 52-10 (October 2022)

The current study investigated the use of ME in toddlers with autism spectrum disorder (ASD) and neurotypical (NT) peers matched on nonverbal cognition. Thirty-two toddlers with ASD and 26 NT toddlers participated in a looking-while-listening task. Images of novel and familiar objects were presented along with a novel or familiar label. Overall, toddlers with ASD showed less efficient looking toward a novel referent when a novel label was presented compared to NT toddlers, controlling for age and familiar word knowledge. However, toddlers with ASD and higher language ability demonstrated more robust use of ME than those with lower language ability.
