Rapid Linguistic Ambiguity Resolution in Young Children with Autism Spectrum Disorder: Eye Tracking Evidence for the Limits of Weak Central Coherence / Noemi HAHN in Autism Research, 8-6 (December 2015)

Titre : Rapid Linguistic Ambiguity Resolution in Young Children with Autism Spectrum Disorder: Eye Tracking Evidence for the Limits of Weak Central Coherence Type de document : Texte imprimé et/ou numérique Auteurs : Noemi HAHN, Auteur ; Jesse SNEDEKER, Auteur ; Hugh RABAGLIATI, Auteur Article en page(s) : p.717-726 Langues : Anglais (eng) Mots-clés : autism language lexical ambiguity homophones eye tracking weak central coherence Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorders (ASD) have often been reported to have difficulty integrating information into its broader context, which has motivated the Weak Central Coherence theory of ASD. In the linguistic domain, evidence for this difficulty comes from reports of impaired use of linguistic context to resolve ambiguous words. However, recent work has suggested that impaired use of linguistic context may not be characteristic of ASD, and is instead better explained by co-occurring language impairments. Here, we provide a strong test of these claims, using the visual world eye tracking paradigm to examine the online mechanisms by which children with autism resolve linguistic ambiguity. To address concerns about both language impairments and compensatory strategies, we used a sample whose verbal skills were strong and whose average age (7; 6) was lower than previous work on lexical ambiguity resolution in ASD. Participants (40 with autism and 40 controls) heard sentences with ambiguous words in contexts that either strongly supported one reading or were consistent with both (John fed/saw the bat). We measured activation of the unintended meaning through implicit semantic priming of an associate (looks to a depicted baseball glove). Contrary to the predictions of weak central coherence, children with ASD, like controls, quickly used context to resolve ambiguity, selecting appropriate meanings within a second. We discuss how these results constrain the generality of weak central coherence. Autism Res 2015, 8: 717–726. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

Titre : The use of prosody during syntactic processing in children and adolescents with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Joshua John DIEHL, Auteur ; Carlyn FRIEDBERG, Auteur ; Rhea PAUL, Auteur ; Jesse SNEDEKER, Auteur Article en page(s) : p.867-884 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : In this study, we employed an eye-gaze paradigm to explore whether children (ages 8–12) and adolescents (ages 12–18) with autism spectrum disorders (ASDs) are able to use prosodic cues to determine the syntactic structure of an utterance. Persons with ASD were compared to typically developing (TD) peers matched on age, IQ, gender, and receptive language abilities. The stimuli were syntactically ambiguous but had a prosodic break that indicated the appropriate interpretation (feel the frog … with the feather vs. feel … the frog with the feather). We found that all groups were equally sensitive to the initial prosodic cues that were presented. Children and teens with ASD used prosody to interpret the ambiguous phrase as rapidly and efficiently as their TD peers. However, when a different cue was presented in subsequent trials, the younger ASD group was more likely to respond in a manner consistent with the initial prosodic cue rather than the new one. Eye-tracking data indicated that both younger groups (ASD and TD) had trouble shifting their interpretation as the prosodic cue changed, but the younger TD group was able to overcome this interference and produce an action consistent with the prosodic cue.
