Both ASD and typically developed adults read sentences that included plausible, implausible and anomalous thematic relations, as their eye movements were monitored. No group differences in the speed of detection of the anomalous violations were found, but the ASD group showed a delay in detection of implausible thematic relations. These findings suggest that there are subtle differences in the speed of world knowledge processing during reading in ASD.

Looking, seeing and believing in autism: Eye movements reveal how subtle cognitive processing differences impact in the social domain / Valerie BENSON in Autism Research, 9-8 (August 2016)

CASTELHANO, Auteur ; Philippa L. HOWARD, Auteur ; Nida LATIF, Auteur ; Keith RAYNER, Auteur Article en page(s) : p.879-887 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  eye movements  on-line cognitive processing  social and perceptual oddities Index. décimale : PER Périodiques Résumé : Adults with High Functioning Autism Spectrum Disorders (ASD) viewed scenes with people in them, while having their eye movements recorded. The task was to indicate, using a button press, whether the pictures were normal, or in some way weird or odd. Oddities in the pictures were categorized as violations of either perceptual or social norms. Compared to a Typically Developed (TD) control group, the ASD participants were equally able to categorize the scenes as odd or normal, but they took longer to respond. The eye movement patterns showed that the ASD group made more fixations and revisits to the target areas in the odd scenes compared with the TD group. Additionally, when the ASD group first fixated the target areas in the scenes, they failed to initially detect the social oddities. These two findings have clear implications for processing difficulties in ASD for the social domain, where it is important to detect social cues on-line, and where there is little opportunity to go back and recheck possible cues in fast dynamic interactions.

No evidence for high inflexible precision of prediction errors in autism during lexical processing / Philippa L. HOWARD in Autism Research, 16-9 (September 2023)  

Public ISBD [article]  inAutism Research > 16-9 (September 2023) . - p.1775-1785 Titre : No evidence for high inflexible precision of prediction errors in autism during lexical processing Type de document : Texte imprimé et/ou numérique Auteurs : Philippa L. HOWARD, Auteur ; Ascensión PAGÁN, Auteur Article en page(s) : p.1775-1785 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Research has shown that information processing differences associated with autism could impact on language and literacy development. This study tested an approach to autistic cognition that suggests learning occurs via prediction errors, and autistic people have very precise and inflexible predictions that result in more sensitivity to meaningless signal errors than non-autistic readers. We used this theoretical background to investigate whether differences in prediction coding influence how orthographic (Experiment 1) and semantic information (Experiment 2) is processed by autistic readers. Experiment 1 used a lexical decision task to test whether letter position information was processed less flexibly by autistic than non-autistic readers. Three types of letter strings: words, transposed letter and substituted letters nonwords were presented. Experiment 2 used a semantic relatedness task to test whether autistic readers processed words with high and low semantic diversity differently to non-autistic readers. Results showed similar transposed letter and semantic diversity effects for all readers; indicating that orthographic and semantic information are processed similarly by autistic and non-autistic readers; and therefore, differences in prediction coding were not evident for these lexical processing tasks.

Processing of co-reference in autism spectrum disorder / Philippa L. HOWARD in Autism Research, 10-12 (December 2017)  

Public ISBD [article]  inAutism Research > 10-12 (December 2017) . - p.1968-1980 Titre : Processing of co-reference in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Philippa L. HOWARD, Auteur ; Simon P. LIVERSEDGE, Auteur ; Valerie BENSON, Auteur Article en page(s) : p.1968-1980 Langues : Anglais (eng) Mots-clés : co-reference  discourse  eye movements  reading Index. décimale : PER Périodiques Résumé : Accuracy for reading comprehension and inferencing tasks has previously been reported as reduced for individuals with autism spectrum disorder (ASD), relative to typically developing (TD) controls. In this study, we used an eye movements and reading paradigm to examine whether this difference in performance accuracy is underpinned by differences in the inferential work required to compute a co-referential link. Participants read two sentences that contained a category noun (e.g., bird) that was preceded by and co-referred to an exemplar that was either typical (e.g., pigeon) or atypical (e.g., penguin). Both TD and ASD participants showed an effect of typicality for gaze durations upon the category noun, with longer times being observed when the exemplar was atypical, in comparison to typical. No group differences or interactions were detected for target processing, and verbal language proficiency was found to predict general reading and inferential skill. The only difference between groups was that individuals with ASD engaged in more re-reading than TD participants. These data suggest that readers with ASD do not differ in the efficiency with which they compute anaphoric links on-line during reading. Autism Res 2017, 10: 1968–1980. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary Individuals with autism spectrum disorder (ASD) have previously been reported to have difficulties with reading comprehension. This study examined whether a difference in the speed with which individuals with ASD form connections between words (co-reference processing) may contribute to comprehension difficulties. No evidence was found to suggest that ASD readers differ to typically developing readers in the speed of co-reference processing. Therefore, this data would suggest that differences in co-reference processing are unlikely to account for reading comprehension difficulties in ASD.
