Bilingual and Monolingual Autistic Toddlers: Language and Social Communication Skills

Parent-led Communication Therapy for Young Bilingual Autistic Children: A Scoping Review

A scoping review of the literature was undertaken using JBI guidelines to map the evidence of parent-led therapy (PLT) for young autistic children (≤ 6 years) raised in bilingual environments. Reviewers used Covidence to screen located sources. Sixteen papers met inclusion criteria. A strong acceleration of reports of PLT for young autistic children measured in bilingual environments was observed, with 93.8% of papers (n = 15) published since 2015. Reporting of participants' language environments (home language(s)/L1s and societal language(s)/L2s) was inconsistent. A large majority of these studies, 87.5% (n = 14) were conducted in North America or in collaboration with a North American institution. Diverse PLT programs and methodologies were identified. There is variation in demographic information collected and outcomes reported. Evidence gaps in the literature are identified and the value of undertaking systematic review on this topic is considered. This scoping review points to the necessity of further empirical research and practice that centres parents in early and specific support for autistic children raised in bilingual environments. Suggestions for improving reporting standards of language profiles are provided.

Bilingualism Predicts Affective Theory of Mind in Autistic Adults

PURPOSE

This study examined the impact of bilingualism on affective theory of mind (ToM) and social prioritization (SP) among autistic adults compared to neurotypical comparison participants.

METHOD

Fifty-two (25 autistic, 27 neurotypical) adult participants (ages 21-35 years) with varying second language (L2) experience, ranging from monolingual to bilingual, completed an affective ToM task. A subset of this sample also completed a dynamic eye-tracking task designed to capture differences in time spent looking at social aspects of a scene (SP). Four language groups were compared on task performance (monolingual autism and neurotypical, bilingual autism and neurotypical), followed by analyses examining the contribution of L2 experience, autism characteristics, and social face prioritization on affective ToM, controlling for verbal IQ. Finally, we conducted an analysis to identify the contribution of SP on affective ToM when moderated by autism status and L2 experience, controlling for verbal IQ.

RESULTS

The monolingual autism group performed significantly worse than the other three groups (bilingual autism, monolingual neurotypical, and bilingual neurotypical) on the affective ToM task; however, there were no significant differences between the bilingual autism group compared to the monolingual and bilingual neurotypical groups. For autistic individuals, affective ToM capabilities were positively associated with both verbal IQ and L2 experience but did not relate to autism characteristics or SP during eye tracking. Neurotypical participants showed greater SP during the eye-tracking task, and SP did not relate to L2 or autism characteristics for autistic individuals. SP and verbal IQ predicted affective ToM performance across autism and neurotypical groups, but this relationship was moderated by L2 experience; SP more strongly predicted affective ToM performance among participants with lower L2 experience (e.g., monolingual) and had less of an impact for those with higher L2 experience.

CONCLUSION

This study provides support for a bilingual advantage in affective ToM for autistic individuals.
