Index. décimale : PER Périodiques Résumé : This study investigated receptive and expressive language outcomes in children with autism spectrum disorder (ASD) with and without a history of language/communication regression, employing three progressively less stringent definitions of regression. Data were derived from a large, longitudinal sample of children with ASD in which regression was assessed at approximately 30 months. Results indicated poorer receptive language and larger discrepancies between receptive and expressive language in the regression group than the group without regression at 44 months but not 66 months. Number of words used before loss predicted receptive language at 44 months. Overall, results suggest that a regression profile in ASD is associated with modest and transient impacts on language outcomes that are no longer discernable at school entry.

Predictive language processing in young autistic children / Kathryn E. PRESCOTT in Autism Research, 15-5 (May 2022)  

Public ISBD [article]  inAutism Research > 15-5 (May 2022) . - p.892-903 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.

Spatial Language and Cognition in Autistic Preschoolers / Kathryn E. PRESCOTT in Journal of Autism and Developmental Disorders, 54-4 (April 2024)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 54-4 (April 2024) . - p.1376-1388 Titre : Spatial Language and Cognition in Autistic Preschoolers Type de document : Texte imprimé et/ou numérique Auteurs : Kathryn E. PRESCOTT, Auteur ; Kimberly CRESPO, Auteur ; Susan ELLIS WEISMER, Auteur Article en page(s) : p.1376-1388 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Purpose: ASD is associated with relative strengths in the visuospatial domain but varying abilities in the linguistic domain. Previous studies suggest parallels between spatial language and spatial cognition in older autistic individuals, but no research to date has examined this relationship in young autistic children. Therefore, the purpose of the present study was to investigate the connection between children?s spatial language production and nonverbal spatial cognition over time. We also examined two potential predictors of spatial language observed in previous literature, ASD symptom severity and parent spatial language input. Methods: In past work investigating spatial language in NT children of the same age, parent-child interactions have been a primary context for study. Therefore, in the present study, we analyzed transcripts of dyadic naturalistic play interactions between autistic children and their parents over three visits from age 30 to 66 months and administered standardized cognitive and ASD diagnostic assessments at each visit. Results: Spatial language production was related to nonverbal spatial cognition even when accounting for overall language production, though the strength of that relationship decreased over time. Parent spatial input (but not ASD severity) significantly predicted children?s spatial language production over and above the effect of overall language production. Conclusion: Spatial language is associated with spatial cognition in young autistic children and appears to reflect the interaction of overall linguistic skills and nonverbal spatial cognitive ability regardless of autism severity. Parent-mediated interventions may be a promising context for increasing spatial language in autistic preschoolers.

The effect of volatility in linguistic input on prediction behavior in autistic toddlers / Kathryn E. PRESCOTT in Autism Research, 17-11 (November 2024)  

Public ISBD [article]  inAutism Research > 17-11 (November 2024) . - p.2305-2318 Titre : The effect of volatility in linguistic input on prediction behavior in autistic toddlers Type de document : Texte imprimé et/ou numérique Auteurs : Kathryn E. PRESCOTT, Auteur ; Janine MATHÉE-SCOTT, Auteur ; Daniel BOLT, Auteur ; Jenny SAFFRAN, Auteur ; Susan ELLIS WEISMER, Auteur Article en page(s) : p.2305-2318 Langues : Anglais (eng) Mots-clés : autistic disorder  child language  cognition  individuality  probability learning Index. décimale : PER Périodiques Résumé : Abstract Domain-general prediction differences have been posited as underlying many aspects of the cognitive-behavioral profile in autism. An interesting potential implication of such differences is hyperplasticity of learning?the idea that autistic individuals may privilege more recent input over the accumulation of prior learning. Because real world language input is highly variable, hyperplasticity could have serious ramifications for language learning. To investigate potential hyperplasticity during a language processing task, we administered an experimental anticipatory eye movement (AEM) task to 2- to 3-year-old autistic children and neurotypical (NT) peers. Autistic children's change in anticipation from before to after a switch in contingencies did not significantly differ from NT counterparts, failing to support claims of hyperplasticity in the linguistic domain. Analysis of individual differences among autistic children revealed that cognitive ability was associated with prediction of the initial, stable contingencies, but neither age nor receptive language related to task performance. Results are discussed in terms of clinical implications and the broader context of research investigating prediction differences in autism.
