Participants included 55 high-risk infants, 21 of whom later met criteria for ASD, 34 low-risk infants, and their caregivers. Results indicated that (a) infants with ASD outcomes used fewer gestures and a lower proportion of developmentally advanced gesture-speech combinations; (b) caregivers of all the infants provided similar rates of contingent responses to their infants' gestures; and (c) gesture production at 12 months predicted subsequent receptive language and ASD outcomes within the high-risk group.

Here's the story: Narrative ability and executive function in autism spectrum disorder / Gabriella GRECO in Research in Autism Spectrum Disorders, 101 (March 2023)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 101 (March 2023) . - 102092 Titre : Here's the story: Narrative ability and executive function in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Gabriella GRECO, Auteur ; Boin CHOI, Auteur ; Kasey MICHEL, Auteur ; Susan FAJA, Auteur Article en page(s) : 102092 Langues : Anglais (eng) Mots-clés : Narrative  Pragmatics  Executive function  Inhibition  Working Memory  Autism Index. décimale : PER Périodiques Résumé : Background Difficulties with narrative have been reported in individuals diagnosed with autism spectrum disorder (ASD), but the role of executive function on narrative ability has not been examined in ASD. In this study, we aimed to (1) examine whether narrative abilities of ASD children differed from neurotypical (NT) children who did not differ in age, sex, and IQ; and (2) investigate relations between executive function and narrative ability in ASD children. Method Narratives were elicited from 64 ASD children and 26 NT children using a wordless picture book and coded to derive several aspects of narrative ability such as propositions, evaluative devices, and self-repairs. Executive functions (specifically, inhibition and working memory) were measured using both experimenter-administered assessment and parent-report measures. Results Compared to NT children, ASD children produced fewer propositions but did not differ in their use of evaluative devices and self-repairs during narrative production. Greater inhibitory challenges related to more self-repairs involving repetition of story elements, whereas working memory did not relate to any of the measures of narrative ability among ASD children. Conclusions This study revealed that narratives by verbally fluent ASD children were shorter and less complex than those by NT children but did not differ in the specific features of narratives. Furthermore, although ASD children did not make more self-repairs than NT children, difficulty with inhibition was related to more self-repairs, indicating more dysfluent narrative production in ASD children, which has implications for intervention.

Parental Language Input Predicts Neuroscillatory Patterns Associated with Language Development in Toddlers at Risk of Autism / Rachel R. ROMEO in Journal of Autism and Developmental Disorders, 52-6 (June 2022)

Forty-six mother-toddler dyads at either high (n=22) or low (n=24) familial risk of ASD completed a longitudinal, prospective study including free-play, resting electroencephalography, and standardized language assessments. Input quantity/quality at 18 months positively predicted expressive language at 24 months, and relationships were stronger for high-risk toddlers. Moderated mediations revealed that input-language relationships were explained by 24-month frontal and temporal gamma power (30-50 Hz) for high-risk toddlers who would later develop ASD. Results suggest that high-risk toddlers may be cognitively and neurally more sensitive to their language environments, which has implications for early intervention.

Reciprocal Influences Between Parent Input and Child Language Skills in Dyads Involving High- and Low-Risk Infants for Autism Spectrum Disorder / Boin CHOI in Autism Research, 13-7 (July 2020)

Parent-infant dyads (high-risk: n = 53; low-risk: n = 33), 19 of whom included an infant later diagnosed with ASD, were videotaped during free play interactions at 12, 18, and 24?months. Measures of parent input were derived from parent-child interactions. Children's language skills were assessed using the Mullen Scales of Early Learning at 12, 18, and 24?months. Results suggested that (a) parents of high- and low-risk infants produced similar word tokens, word types, and proportions of contingent verbal responses, but parents of high-risk infants used shorter mean length of utterances (MLU) than parents of low-risk infants at 18 and 24?months; (b) parents' MLU at 18?months was positively associated with their infants' language at the subsequent visit after 6?months, regardless of group; and (c) infants' language at 18?months was positively associated with parents' MLU at the subsequent visit after 6?months in the high-risk group only. These findings contribute to our understanding of the mechanisms underlying early language learning of high-risk infants who have an increased risk for language delays and deficits.

In this study, we looked at parent input to infants at high- and low-risk for autism spectrum disorder and relations between parent input and child language in the first 2?years of life. We found that parents of high- and low-risk infants provided similar quantity and quality of input, except shorter average length of utterances at 18 and 24?months in the high-risk group. Also, there were bidirectional relations between parent input and child language at 18 and 24?months in high-risk pairs, suggesting that parents and children collectively shape the early language environment.
