RESUMO
Discourse studies investigating differences in the socio-communicative profiles of autistic (ASD) and neurotypical (NT) individuals have mostly relied on orthographic transcriptions, without taking prosodic information into account. However, atypical prosody is ubiquitous in ASD and a more accurate representation of their discourse abilities should also include prosodic cues. This exploratory study addresses this gap by segmenting the spoken discourse of 12 ASD and NT adults using the framework of Basic Discourse Units (BDUs). BDUs result from the mapping of syntactic boundaries on prosodic units, which can coincide in different ways and are associated with different discourse strategies. We hypothesized that the discourse of ASD adults would display more atypical strategies than NT adults, reflecting a 'pedantic' style and more difficulties in managing ongoing discourse. While ASD adults did not produce more discourse units associated with didactic or pedantic strategies than NT adults, they did produce less units associated with strategies of interactional regulation. This study provides initial evidence that multidimensional linguistic units, such as BDUs can help differentiate speech delivery strategies of ASD adults from those of their NT peers, even based on simple prosodic cues like silent pauses.

PURPOSE: Predictive coding theories posit that autism is characterized by an over-adjustment to prediction errors, resulting in frequent updates of prior beliefs. Atypical weighting of prediction errors is generally considered to negatively impact the construction of stable models of the world, but may also yield beneficial effects. In a novel associative learning paradigm, we investigated whether unexpected events trigger faster learning updates in favour of subtle but fully predictive cues in autistic children compared to their non-autistic counterparts. We also explored the relationship between children's language proficiency and their predictive performances. METHODS: Anticipatory fixations and explicit predictions were recorded during three associative learning tasks with deterministic or probabilistic contingencies. One of the probabilistic tasks was designed so that a fully predictive but subtle cue was overshadowed by a less predictive salient one. RESULTS: Both autistic and non-autistic children based their learning on the salient cue, and, contrary to our predictions, showed no signs of updating in favour of the subtle cue. While both groups demonstrated associative learning, autistic children made less accurate explicit predictions than their non-autistic peers in all tasks. Explicit prediction performances were positively correlated with language proficiency in non-autistic children, but no such correlation was observed in autistic children. CONCLUSION: These results suggest no over-adjustment to prediction errors in autistic children and highlight the need to control for general performance in cue-outcome associative learning in predictive processing studies. Further research is needed to explore the nature of the relationship between predictive processing and language development in autism.
RESUMO
Recent findings suggest that stigma and camouflaging contribute to mental health difficulties for autistic individuals, however, this evidence is largely based on UK samples. While studies have shown cross-cultural differences in levels of autism-related stigma, it is unclear whether camouflaging and mental health difficulties vary across cultures. Hence, the current study had two aims: (1) to determine whether significant relationships between autism acceptance, camouflaging, and mental health difficulties replicate in a cross-cultural sample of autistic adults, and (2) to compare these variables across cultures. To fulfil these aims, 306 autistic adults from eight countries (Australia, Belgium, Canada, Japan, New Zealand, South Africa, the United Kingdom, and the United States) completed a series of online questionnaires. We found that external acceptance and personal acceptance were associated with lower levels of depression but not camouflaging or stress. Higher camouflaging was associated with elevated levels of depression, anxiety, and stress. Significant differences were found across countries in external acceptance, personal acceptance, depression, anxiety, and stress, even after controlling for relevant covariates. Levels of camouflaging also differed across countries however this effect became non-significant after controlling for the covariates. These findings have significant implications, identifying priority regions for anti-stigma interventions, and highlighting countries where greater support for mental health difficulties is needed.

Background: In recent years, there have been increasing discussions surrounding the appropriate terminology to talk about autism. Initially, this debate revolved around the use of person-first language (e.g., person with autism) versus identity-first language (IFL; e.g., autistic person) but has recently expanded to other autism-related terms (e.g., deficits). However, to date, studies investigating autism-related language preferences have been limited to English-speaking countries, and little is known about preferences in other languages. This study addresses this gap by investigating the language preferences of French-speaking autistic adults. Methods: Five hundred and forty-one French-speaking autistic adults (formal diagnosis and self-identified) completed an online survey where they selected terms they preferred to use to talk about: (1) the nomenclature of autism; (2) an autistic person; (3) someone's autistic identity; (4) autism more broadly; (5) the abilities of autistic people; and (6) people without a diagnosis of autism. Participants also revealed more about their language preferences via an open-text response. Results: The most preferred terms were "Autisme," "Personne autiste," "Autiste," "Est Autiste," "Différence neurologique/cérébrale," "Différences," "Difficultés," "Personne neurotypique," "Neurotypique," and "Personne non-autiste." To better understand these preferences, participants' open comments were analyzed, revealing further support for IFL and the social model of disability, and a preference for simple, precise, and validated terms. Conclusions: These results are consistent with autism terminology preferences in English-speaking countries and provide additional insight into the reasons underlying these preferences. Such work has implications for informing the language of researchers, clinicians, and other professionals in the field, as well as the general public.
Community brief: Why is this an important issue?: More and more research is investigating which words should be used to talk about autism. Initially, this discussion revolved around the use of person-first language (e.g., person with autism) versus identity-first language (e.g., autistic person) but has recently expanded to other autism-related terms (e.g., disorder, deficits, high-functioning autism). To date, all the studies on this topic have focused on language preferences in English-speaking countries, and little is known about preferences in other languages.What was the purpose of this study?: We wanted to know whether French-speaking autistic adults would show similar or different autism-related language preferences than English-speaking autistic individuals. We also wanted to know the reasons for these language preferences.What did the researchers do?: In an online survey, we asked 541 French-speaking autistic adults around the world what terms they prefer to use to talk about (1) the nomenclature of autism, (2) an autistic person, (3) someone's autistic identity, (4) autism more broadly, (5) the abilities of autistic people, and (6) someone without an autism diagnosis. Participants also had the opportunity to tell us more about their language preferences in an open comment.What were the results of this study?: The most preferred terms were "Autisme," "Personne autiste," "Autiste," "Est Autiste," "Différence/neurologique," "Différences," "Difficultés," "Personne neurotypique," "Neurotypique," and "Personne non autiste." To better understand the reasons underlying these preferences, participants' open comments were analyzed, revealing further support for identity-first language and the social model of disability, and a preference for simple, precise, and validated terms. What do these findings add to what was already known?: We previously knew about language preferences of English-speaking autistic people. This study extends these findings by showing that French-speaking autistic adults also prefer terms that reflect the ideas of identity-first language (e.g., "Est Autiste," "Personne autiste") and the social model of disability (e.g., "Différence," "Handicap"). We also show that these are not the only reasons behind language preferences: Term simplicity, precision, and validity are also important when talking about autism.What are the potential weaknesses in the study?: The reported preferences are not representative of all autistic individuals, as our sample did not include children and adolescents. In addition, we did not make specific adaptations to our questionnaire for non-speaking people or people with intellectual difficulties, so we do not know to what extent their opinions are represented in our data. Further, recruitment was done almost exclusively online, resulting in a self-selecting recruitment method for our sample (i.e., participants who have access to Internet and a computer). Finally, participants who responded to the advertisements and completed the questionnaire are probably interested in the debate regarding language to talk about autism. Therefore, our sample may be more representative of the online autistic, pro-neurodiversity community.How will these findings help autistic adults now or in the future?: This study is the first to look at the language preferences of French-speaking autistic adults. Further, our results have substantial implications for informing the language of researchers, clinicians, and other professionals in the field, as well as the general public.
RESUMO
Autism Spectrum Disorder (ASD) is often described as being characterised by a uniform pragmatic impairment. However, recent evidence suggests that some areas of pragmatic functioning are preserved. This study seeks to determine to which extent context-based derivation of non-linguistically encoded meaning is functional in ASD. We compare the performance of 24 adults with ASD, and matched neuro-typical adults in two act-out pragmatic tasks. The first task examines generation of indirect request interpretations, and the second the comprehension of irony. Intact contextual comprehension of indirect requests contrasts with marked difficulties in understanding irony. These results suggest that preserved pragmatics in ASD is limited to egocentric processing of context, which does not rely on assumptions about the speaker's mental states.
