A critical gap in existing research is the impact of bilingualism on the ability of children with ASD to understand and produce non-literal speech. This study addresses this gap by examining the comprehension and production of metaphors and similes in monolingual and bilingual Greek-speaking children with high-functioning ASD. To the best of our knowledge, this is the first study to investigate these abilities in bilingual children with ASD. Thirty-three monolingual and 18 bilingual children participated in tasks designed to assess comprehension, production, and error patterns for metaphors and similes. The study has also investigated the roles of non-verbal intelligence, language skills (expressive vocabulary), and executive functions (working memory) in the children's performance in the metaphor and simile tasks. Results showed that the two groups did not differ in metaphor comprehension; however, bilingual autistic children with higher non-verbal intelligence appeared to have superior performance in metaphor comprehension compared to their bilingual peers with lower non-verbal intelligence. The bilingual autistic children outperformed their monolingual peers in metaphor production, likely due to their higher non-verbal intelligence ability, despite the fact that the bilingual group had lower expressive vocabulary scores than the monolingual children. Simile comprehension, on the other hand, favored monolingual children, while no significant group differences were observed in simile production. Regarding errors, both groups exhibited similar error patterns, with literal interpretations being the dominant error type across both groups, suggesting that pragmatic language difficulty is a hallmark feature in ASD. The findings challenge the misconception that bilingualism hinders language development in children with ASD and highlight its potential to provide benefits in the realm of non-literal language processing.

Bilingualism effects in pronoun comprehension: Evidence from children with autism / Vasileia SKRIMPA in Autism Research, 15-2 (February 2022)  

Public ISBD [article]  inAutism Research > 15-2 (February 2022) . - p.270-283 Titre : Bilingualism effects in pronoun comprehension: Evidence from children with autism Type de document : texte imprimé Auteurs : Vasileia SKRIMPA, Auteur ; Vasilina SPANOU, Auteur ; Christiane BONGARTZ, Auteur ; Eleni PERISTERI, Auteur ; Maria ANDREOU, Auteur ; Despina PAPADOPOULOU, Auteur Article en page(s) : p.270-283 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  bilingualism  language deficits  pronoun resolution Index. décimale : PER Périodiques Résumé : The prevalence of autism worldwide has risen steadily in the last two decades, while bilingualism is also becoming increasingly prevalent in today's rapidly globalizing world. The current study aimed to investigate bilingualism effects in the pronoun resolution skills of children with autism in comparison to age-matched monolingual children with autism, as well as monolingual and bilingual children of typical development (Ν = 20 participants per group). Results showed that autistic children had general difficulty anchoring ambiguous pronouns to entities that were linguistically expressed in discourse, yet, the bilingual children with autism were more sensitive to the topicality of the entities in syntactic subject position and more prone to identify them as suitable referents of ambiguous null pronouns as compared to their monolingual peers. The findings suggest that bilingualism is not detrimental to autistic children's pronoun resolution skills. The current study aimed at determining how bilingualism influences ambiguous pronoun comprehension in children with autism as compared to bilingual and monolingual children of typical development. The findings show that bilingualism was not detrimental to the autistic children's pronoun resolution skills, further suggesting that having acquired more than one language does not exacerbate autistic children's deficits in the comprehension of pronouns.

Cognitive flexibility in autism: Evidence from young autistic children / Maria ANDREOU in Autism Research, 15-12 (December 2022)

Thirty-six autistic children (72-83 months) and 200 age-matched typically-developing children were assessed on the Children's Color Trails Test (CCTT), a semantic and a phonemic verbal fluency task. The results showed that the autistic children performed worse than their neurotypical peers in the switching component of the CCTT. In the fluency tests, the autistic group generated overall fewer word items than their neurotypical peers, however, their poorer performance was driven by specific linguistic stimuli in the fluency tasks. The findings suggest that cognitive flexibility for the autistic children was affected in the nonverbal CCTT only, while poor performance in semantic and phonemic fluency seemed to be inherent to the language properties of the verbal fluency tasks.

Figurative language processing in autism spectrum disorders: A review / Stella LAMPRI in Autism Research, 17-4 (April 2024)  

Public ISBD [article]  inAutism Research > 17-4 (April 2024) . - p.674-689 Titre : Figurative language processing in autism spectrum disorders: A review Type de document : texte imprimé Auteurs : Stella LAMPRI, Auteur ; Eleni PERISTERI, Auteur ; Theodoros MARINIS, Auteur ; Maria ANDREOU, Auteur Article en page(s) : p.674-689 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Impairments in the broader domain of pragmatics are considered to be a defining feature of Autism Spectrum Disorders (ASD). A challenging aspect of pragmatic competence is the ability to process nonliteral language. Interestingly, previous studies in figurative language comprehension in ASD have demonstrated conflicting results regarding participants' performance. The main scientific debate focuses on the underlying skills which facilitate processing of nonliteral speech in ASD. Namely, Theory of Mind (ToM), language abilities and Executive functions (EFs) are regarded as factors affecting autistic individuals' performance. This review addresses figurative language comprehension in ASD in light of the above three interpretive accounts. We reviewed data from recent studies in this field concluding that autistic children indeed encounter systematic difficulties in the processing of non-literal language. Moreover, only ToM and verbal skills were found to correlate the most with figurative language comprehension in ASD. Notably, we found that differences related to research methodology and tasks' properties may have led to discrepancies between studies' results. Finally, we argue that future studies should encompass in their experimental design figurative comprehension tasks with minimal linguistic demands and also measures of ToM, verbal ability and EFs in order to shed more light in the independent contribution of those skills to the processing of nonliteral language in ASD.

Integrating artificial intelligence and natural language processing to investigate lexical errors in autistic preschoolers / Maria ANDREOU in Research in Autism, 130 (February 2026)  

Public ISBD [article]  inResearch in Autism > 130 (February 2026) . - p.202771 Titre : Integrating artificial intelligence and natural language processing to investigate lexical errors in autistic preschoolers Type de document : texte imprimé Auteurs : Maria ANDREOU, Auteur ; Charalambos K. THEMISTOCLEOUS, Auteur ; Eleni PERISTERI, Auteur Article en page(s) : p.202771 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Preschool-aged children  Lexical errors  Natural language processing Index. décimale : PER Périodiques Résumé : Expressive vocabulary has been characterized as a strength in the autistic population, with most studies focusing on the cues that autistic children use to learn new words. There is little knowledge about the organization of lexical networks in autism. This study aimed to characterize the lexical retrieval errors in a cohort of 60 Greek-speaking autistic preschoolers by combining manual coding with distributional semantics. Children completed a standardized picture-naming task yielding 745 errors classified into four error types: semantic, visual, phonological, and irrelevant. To quantify each error’s proximity to its intended target, we applied a pre-trained word embeddings model to derive continuous semantic proximity scores. More than half of the children exhibited expressive vocabulary abilities which were well below their chronological age level, while the opposite pattern was observed for one third of the children. Within this sample, semantic errors were predominant, and word embedding-derived distances corroborated the manual taxonomy: semantic substitutions displayed the highest proximity to target concepts, followed in descending order by phonological, visual, and irrelevant errors. Semantic errors showed no association with vocabulary delay, whereas irrelevant and visual errors increased with vocabulary delay, suggesting reduced semantic constraints in children whose vocabulary age equivalents were lower than their chronological ages. These findings underscore that naming errors in autistic children are not random but organized along graded semantic relationships, paving the way for computational modeling of lexical networks in this population. Integrating distributional-semantic modeling with traditional error analysis yields novel quantitative metrics for distinguishing between lexical error types, and paves the way for investigations into the development of lexical networks in autism.
