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 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.

Specificity of Phonological Representations for Children with Autism Spectrum Disorder / Ron POMPER in Journal of Autism and Developmental Disorders, 49-8 (August 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-8 (August 2019) . - p.3351-3363 Titre : Specificity of Phonological Representations for Children with Autism Spectrum Disorder Type de document : texte imprimé Auteurs : Ron POMPER, Auteur ; Susan ELLIS WEISMER, Auteur ; Jenny SAFFRAN, Auteur ; Jan EDWARDS, Auteur Article en page(s) : p.3351-3363 Langues : Anglais (eng) Mots-clés : Autism  Eye-tracking  Lexical processing  Phonology  Weak central coherence Index. décimale : PER Périodiques Résumé : This study investigated whether children with autism spectrum disorder (ASD) are sensitive to mispronunciations of familiar words and compared their sensitivity to children with typical-development. Sixty-four toddlers with ASD and 31 younger, typical controls participated in a looking-while-listening task that measured their accuracy in fixating the correct object when it was labelled with a correct pronunciation versus mispronunciation. A cognitive style that prioritizes processing local, rather than global features, as claimed by the weak central coherence theory, predicts that children with ASD should be more sensitive to mispronunciations than typical controls. The results, however, reveal no differences in the effect of mispronunciations on lexical processing between groups, even when matched for receptive language or non-verbal cognitive skills.

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.
