Brief Report: Children on the Autism Spectrum are Challenged by Complex Word Meanings / S. FLOYD in Journal of Autism and Developmental Disorders, 51-7 (July 2021)
[article]
Titre : Brief Report: Children on the Autism Spectrum are Challenged by Complex Word Meanings Type de document : Texte imprimé et/ou numérique Auteurs : S. FLOYD, Auteur ; C. JEPPSEN, Auteur ; A. E. GOLDBERG, Auteur Article en page(s) : p.2543-2549 Langues : Anglais (eng) Mots-clés : Adolescent Autism Spectrum Disorder/complications Autistic Disorder Child Child Development Disorders, Pervasive Cognition Communication Humans Learning Linguistics Male Verbal Learning Vocabulary Language Polysemy Index. décimale : PER Périodiques Résumé : The current work suggests that two factors conspire to make vocabulary learning challenging for youth on the Autism spectrum: (1) a tendency to focus on specifics rather than on relationships among entities and (2) the fact that most words are associated with distinct but related meanings (e.g. baseball cap, pen cap, bottle cap). Neurotypical (NT) children find it easier to learn multiple related meanings of words (polysemy) in comparison to multiple unrelated meanings (homonymy). We exposed 60 NT children and 40 verbal youth on the Autism spectrum to novel words. The groups' performance learning homonyms was comparable, but unlike their NT peers, youth on the spectrum did not display the same advantage for learning polysemous words compared to homonyms.

Prior work suggests pragmatic language differences may run in families. This study examined specific pragmatic difficulties (i.e., linguistic mazes and perseverations) in boys (9-18 years) with idiopathic ASD (n?=?26) and FXS+ASD (n?=?29), and relationships with maternal maze use. Language samples were obtained separately for boys and mothers. Nonparametric analyses suggested that boys largely did not differ in their rates of mazes, but that boys with FXS+ASD exhibited more perseverations. Mazes were correlated between fragile X dyads. Maternal mazes were correlated with child perseverations among idiopathic ASD dyads. These findings have implications for the etiological significance of ASD-related language phenotypes.

Titre : Competing Perceptual Salience in a Visual Word Recognition Task Differentially Affects Children With and Without Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Courtney E. VENKER, Auteur ; J. MATHÉE, Auteur ; D. NEUMANN, Auteur ; J. EDWARDS, Auteur ; Jenny SAFFRAN, Auteur ; S. ELLIS WEISMER, Auteur Article en page(s) : p.1147-1162 Langues : Anglais (eng) Mots-clés : Aptitude Autism Spectrum Disorder Child Child, Preschool Humans Infant Language Learning Linguistics attention child cues information seeking behavior language language development Index. décimale : PER Périodiques Résumé : Differences in visual attention have long been recognized as a central characteristic of autism spectrum disorder (ASD). Regardless of social content, children with ASD show a strong preference for perceptual salience-how interesting (i.e., striking) certain stimuli are, based on their visual properties (e.g., color, geometric patterning). However, we do not know the extent to which attentional allocation preferences for perceptual salience persist when they compete with top-down, linguistic information. This study examined the impact of competing perceptual salience on visual word recognition in 17 children with ASD (mean age 31?months) and 17 children with typical development (mean age 20?months) matched on receptive language skills. A word recognition task presented two images on a screen, one of which was named (e.g., Find the bowl!). On Neutral trials, both images had high salience (i.e., were colorful and had geometric patterning). On Competing trials, the distracter image had high salience but the target image had low salience, creating competition between bottom-up (i.e., salience-driven) and top-down (i.e., language-driven) processes. Though both groups of children showed word recognition in an absolute sense, competing perceptual salience significantly decreased attention to the target only in the children with ASD. These findings indicate that perceptual properties of objects can disrupt attention to relevant information in children with ASD, which has implications for supporting their language development. Findings also demonstrate that perceptual salience affects attentional allocation preferences in children with ASD, even in the absence of social stimuli. LAY SUMMARY: This study found that visually striking objects distract young children with autism spectrum disorder (ASD) from looking at relevant (but less striking) objects named by an adult. Language-matched, younger children with typical development were not significantly affected by this visual distraction. Though visual distraction could have cascading negative effects on language development in children with ASD, learning opportunities that build on children's focus of attention are likely to support positive outcomes.

This cross-linguistic study evaluated the performance of imitating Cantonese lexical tones and their non-linguistic (nonspeech) counterparts by Cantonese- and Mandarin-speaking children with and without ASD. Acoustic analyses showed that, compared with typically developing peers, children with ASD exhibited increased pitch variations when imitating lexical tones, while performed similarly when imitating the nonspeech counterparts. Furthermore, Mandarin-speaking children with ASD failed to exploit the phonological knowledge of segments to improve the imitation accuracy of non-native lexical tones. These findings help clarify the speech-specific pitch processing atypicality and phonological processing deficit in tone-language-speaking children with ASD.

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.
