Eye movements during processing of text requiring bridging inferences in adolescents with higher functioning autism spectrum disorders: A preliminary investigation / Frank J. SANSOSTI in Research in Autism Spectrum Disorders, 7-12 (December 2013)

Titre : Eye movements during processing of text requiring bridging inferences in adolescents with higher functioning autism spectrum disorders: A preliminary investigation Type de document : Texte imprimé et/ou numérique Auteurs : Frank J. SANSOSTI, Auteur ; Christopher WAS, Auteur ; Katherine A. RAWSON, Auteur ; Brittany L. REMAKLUS, Auteur Article en page(s) : p.1535-1542 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Eye-tracking Eye-movements Bridging inferences Text comprehension Index. décimale : PER Périodiques Résumé : Abstract In this study, 18 children with higher functioning autism (HFASD) and 16 controls read short, two-sentence passages that necessitated a bridging inference for comprehension and responded to a general knowledge question that was either primed or unprimed by the inference. We measured mean reading times and correct responses to knowledge questions, as well as recorded the eye-movements of the participants while reading. Analysis of reaction times to general knowledge questions were faster for questions in relevant context as compared to those in irrelevant contexts, suggesting that children with HFASD were able to build the bridging inferences necessary for comprehension. Eye-movement data revealed that children with HFASD spent more time fixating on text, made more fixations overall, and made more regressions (i.e., moving backward within the text) while reading than did controls. Implications of these findings and suggestions for future research are offered.

NOENS, Auteur Article en page(s) : p.913-922 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Weak central coherence Context effects Scene perception Eye-movements Index. décimale : PER Périodiques Résumé : Several studies have investigated contextual influences on visual object processing in individuals with autism spectrum disorder (ASD) and failed to find reduced context effects. However, these studies did not properly account for local inter-object effects and/or the influence of post-perceptual processes, leaving it unclear whether individuals with ASD display equally large global top-down effects of context, or whether they rely on a more local mechanism producing the same result. In this study, an eye-movement paradigm was used to investigate implicitly induced context effects on visual object processing in children with ASD compared to matched controls. To find out whether the context effects in the ASD group were, to the same extent, due to early top-down influences on object recognition, we also examined the interaction between context effects and the ease of object recognition. Both groups displayed equally large context effects and congruent contextual information facilitated object recognition to the same extent in both groups. This indicates that the context effects in the ASD group did not result from the operation of a more local, less top-down mechanism. These findings contradict predictions based on the weak central coherence account. However, a good alternative to explain all inconsistencies is currently lacking.

Gaze measures included the children’s spontaneous tendency to look at the correct (attended) toy, and the latency of their correct responses. In addition to group differences (AD vs. TD), we found that in AD, accuracy of performance was specifically related to adaptive communication skills. The study also indicated that the latency of correct gaze shifts is related to verbal intelligence. These results have direct implications for our understanding of (responsive) joint attention impairments in AD.
