Titre : Predictors of language regression and its association with subsequent communication development in children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Andrew PICKLES, Auteur ; Nicola WRIGHT, Auteur ; Rachael BEDFORD, Auteur ; Mandy STEIMAN, Auteur ; Eric DUKU, Auteur ; Teresa BENNETT, Auteur ; Stelios GEORGIADES, Auteur ; Connor M. KERNS, Auteur ; Pat MIRENDA, Auteur ; Isabel M. SMITH, Auteur ; Wendy J. UNGAR, Auteur ; Tracy VAILLANCOURT, Auteur ; Charlotte WADDELL, Auteur ; Anat ZAIDMAN-ZAIT, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; Peter SZATMARI, Auteur ; Mayada ELSABBAGH, Auteur Article en page(s) : p.1243-1251 Langues : Anglais (eng) Mots-clés : Child Child, Preschool Humans Autism Spectrum Disorder/diagnosis Autistic Disorder/complications Longitudinal Studies Prospective Studies Language Development Disorders/complications Speech Language Development Language autism development Index. décimale : PER Périodiques Résumé : BACKGROUND: Language regression, broadly defined as the loss of acquired language skills in early childhood, is a distinctive feature of autism. Little is known about the factors underlying regression or the prognosis of children who exhibit regression. We examine potential predictors of language regression and test its association with language development in a prospective longitudinal sample of children with autism spectrum disorder (ASD) from diagnosis to age 10 years. METHODS: We analysed data from Pathways in ASD, a prospective longitudinal study of 421 children enrolled around the time of an autism diagnosis between 2 and 5 years. Autism Diagnostic Interview-Revised data were available for 408 children, of whom 90 (22%) were classified as having language regression. RESULTS: Demographic and other health factors including caregiver education, family income, child sex, reported seizures, and age of enrolment did not differ between children with and without language regression. Children with language regression walked earlier and attained first words sooner than those without regression. However, both groups attained phrase speech at comparable ages. Those with regression exhibited greater delays in expressive and receptive communication over the follow-up period, although this effect was attenuated when accounting for baseline differences in motor and cognitive ability. Overall, those with language regression continued to exhibit expressive but not receptive communication delay compared to those without regression. Communication trajectories were heterogeneous to age 10 years, irrespective of regression status. CONCLUSIONS: Although language regression can be alarming, our findings confirm that its occurrence does not necessarily foreshadow worse developmental outcomes relative to those without regression. Although a discrepancy in age-equivalent communication skills may persist, this can be expected to be of less practical importance with rising average levels of skills. Future studies need to account for the significant variability in language trajectories by considering factors beyond developmental regression.

Titre : Predictive language processing in young autistic children Type de document : Texte imprimé et/ou numérique Auteurs : Kathryn E. PRESCOTT, Auteur ; Janine MATHÉE-SCOTT, Auteur ; Tracy REUTER, Auteur ; Jan EDWARDS, Auteur ; Jenny SAFFRAN, Auteur ; Susan ELLIS WEISMER, Auteur Article en page(s) : p.892-903 Langues : Anglais (eng) Mots-clés : Adolescent Autism Spectrum Disorder/complications Autistic Disorder/complications Child Child, Preschool Humans Infant Language Language Development Disorders/complications Linguistics anticipatory language processing autism spectrum disorder language development prediction receptive language Index. décimale : PER Périodiques Résumé : Recent theories propose that domain-general deficits in prediction (i.e., the ability to anticipate upcoming information) underlie the behavioral characteristics associated with autism spectrum disorder (ASD). If these theories are correct, autistic children might be expected to demonstrate difficulties on linguistic tasks that rely on predictive processing. Previous research has largely focused on older autistic children and adolescents with average language and cognition. The present study used an eye-gaze task to evaluate predictive language processing among 3- to 4-year-old autistic children (n =?34) and 1.5- to 3-year-old, language-matched neurotypical (NT) children (n =?34). Children viewed images (e.g., a cake and a ball) and heard sentences with informative verbs (e.g., Eat the cake) or neutral verbs (e.g., Find the cake). Analyses of children's looking behaviors indicated that young autistic children, like their language-matched NT peers, engaged in predictive language processing. Regression results revealed a significant effect of diagnostic group, when statistically controlling for age differences. The NT group displayed larger difference scores between the informative and neutral verb conditions (in looks to target nouns) compared to the ASD group. Receptive language measures were predictive of looking behavior across time for both groups, such that children with stronger language skills were more efficient in making use of informative verbs to process upcoming information. Taken together, these results suggest that young autistic children can engage in predictive processing though further research is warranted to explore the developmental trajectory relative to NT development. LAY SUMMARY: This study found that 3- to 4-year-old autistic children and younger, language-matched neurotypical (NT) children both used verbs to predict upcoming nouns in sentences like "Eat the cake." For both autistic and NT children, those with stronger language skills were able to predict upcoming nouns more quickly.
