Index. décimale : PER Périodiques Résumé : BACKGROUND: Language difficulties are common in autism, with several theoretical perspectives proposing that difficulties in forming and updating predictions may underlie the cognitive profile of autism. However, research examining prediction in the language domain among autistic children remains limited, with inconsistent findings regarding prediction efficiency and insufficient investigation of how autistic children incrementally integrate multiple semantic elements during language processing. This study addresses these gaps by investigating both prediction efficiency and incremental processing strategy during spoken language comprehension in autistic children compared to neurotypical peers. METHODS: Using the visual world paradigm, we compared 45 autistic children (3-8 years) with 52 age-, gender-, and verbal IQ-matched neurotypical children. Participants viewed arrays containing a target object and three semantically controlled distractors (agent-related, action-related, and unrelated) while listening to subject-verb-object structured sentences. Eye movements were recorded to analyze fixation proportions. We employed cluster-based permutation analysis to identify periods of sustained biased looking, growth curve analysis to compare fixation trajectories, and divergence point analysis to determine the onset timing of predictive looking. RESULTS: Both groups demonstrated predictions during spoken language comprehension and employed similar incremental processing strategies, showing increased fixations to both target objects and action-related distractors after verb onset despite the latter's incompatibility with the agent. However, autistic children exhibited reduced prediction efficiency compared to neurotypical peers, evidenced by significantly lower proportions of and slower growth rates in fixations to target objects relative to unrelated distractors, and delayed onset of predictive looking. Reduced prediction efficiency was associated with higher levels of autism symptom severity in the autistic group and increased autistic traits across both groups, with autism-related communication difficulties showing the most robust associations. LIMITATIONS: Our sample included only autistic children without language impairments, limiting generalizability to the broader autism spectrum. The task employed only simple sentence structures in controlled experimental settings, which may not fully capture language processing patterns in naturalistic communication contexts. CONCLUSIONS: While autistic children employ similar incremental processing strategies to neurotypical peers during language comprehension, they demonstrate reduced prediction efficiency. Autism symptom severity and autistic traits varied systematically with prediction efficiency, with autism-related communication difficulties showing the strongest associations. These findings enhance our understanding of language processing mechanisms in autism and suggest that interventions targeting language development might benefit from addressing prediction efficiency, such as providing additional processing time and gradually increasing the complexity of semantic integration tasks.

The impact of expressive language development and the left inferior longitudinal fasciculus on listening and reading comprehension / Stephanie N. DEL TUFO in Journal of Neurodevelopmental Disorders, 11-1 (December 2019)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 11-1 (December 2019) . - 37 Titre : The impact of expressive language development and the left inferior longitudinal fasciculus on listening and reading comprehension Type de document : texte imprimé Auteurs : Stephanie N. DEL TUFO, Auteur ; F. Sayako EARLE, Auteur ; Laurie E. CUTTING, Auteur Article en page(s) : 37 Langues : Anglais (eng) Mots-clés : Child  Comprehension/physiology  Diffusion Magnetic Resonance Imaging  Female  Humans  Language Development  Language Development Disorders/diagnosis/pathology  Male  Neural Pathways  Prefrontal Cortex/pathology/physiopathology  Reading  Speech Perception/physiology  Temporal Lobe/pathology/physiopathology  Developmental disorder  Expressive language development  Genre  Inferior longitudinal fasciculus  Intervention  Longitudinal  Modality  Passage comprehension  Socioeconomic  Survival analysis Index. décimale : PER Périodiques Résumé : BACKGROUND: During the first 3-years of life, as the brain undergoes dramatic growth, children begin to develop speech and language. Hallmarks of this progression are seen when children reach developmental milestones, forming the foundation of language. Expressive language milestones, such as the production of a child's first word, are delayed in 5-8% of children. While for some children delays in reaching these milestones are harbingers of developmental disorders, for others expressive language delays appear to resolve. Regardless of whether or not early language skills appear resolved, difficulty with later comprehension is a likely outcome. Whether this heightened risk for poor comprehension differs based on text features, individual characteristics, or receipt of intervention remains unknown. Moreover, this relationship between expressive language development and comprehension is not yet linked to neurobiology, though the inferior longitudinal fasciculus (ILF) is a potential neurobiological correlate. Therefore, we investigated the impact of, and interactions between, expressive language development, early intervention, and the ILF on comprehension. METHODS: Longitudinal recurrent survival analyses predicted the risk of answering a comprehension question incorrectly. Predictors of comprehension included expressive language development, passage features, participant characteristics, fractional anisotropy, receipt of early intervention, and later diagnosis of speech or language disorders. RESULTS: Children with later expressive language milestones had poorer comprehension. When comprehension text features were examined, children with later milestones had poorer listening and reading comprehension, and poorer narrative and expository comprehension. The left ILF acted as a neurodevelopmental correlate, one that moderated the relationship between expressive language milestones and comprehension. Specifically, the left ILF exacerbated the relationship for those who did not receive early intervention and buffered the relationship for those who received intervention services. Early intervention decreased the risk of poor comprehension by 39% for children later diagnosed with a speech or language disorder. CONCLUSIONS: Early intervention should be provided for children with delayed expressive language milestones, particularly those who are at risk for speech or language disorders. The ILF plays a critical role in the relationship between expressive language development and comprehension, which may be that of a protective factor for children with the most severe early issues with speech and language.

Comparison of Disfluent and Ungrammatical Speech of Preadolescents with and without ASD / Mari WIKLUND in Journal of Autism and Developmental Disorders, 51-8 (August 2021)

The ASD data were from authentic group therapy sessions and neurotypical data from teacher-led group discussions. The proportion of disfluencies and ungrammatical expressions was greater in the speech of participants with ASD (26.4%) than in the control group (15.5%). Furthermore, a qualitative difference was noted: The ASD group produced long, complex disfluent turns with word searches, self-repairs, false starts, fillers, prolongations, inconsistent syntactic structures and grammatical errors, whereas in the control group, the disfluencies were mainly fillers and sound prolongations. The disfluencies and ungrammatical expressions occurring in the ASD participants' interactions also caused comprehension problems.
