Cross-cultural variation in experiences of acceptance, camouflaging and mental health difficulties in autism: A registered report.

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.

Autism-Related Language Preferences of French-Speaking Autistic Adults: An Online Survey.

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.

How do autistic adults use syntactic and prosodic cues to manage spoken discourse?

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.

Phonetic Inflexibility in Autistic Adults.

This study examined whether the atypical speech style that is frequently reported in autistic adults is underpinned by an inflexible production of phonetic targets. In a first task, 20 male autistic adults and 20 neuro-typicals had to read and produce native vowels. To assess the extent to which phonetic inflexibility is due to an overall fine-grained control of phonetic behavior or to a lack of flexibility in the realization of one's phonological repertoire, the second task asked participants to reproduce artificial vowel-like sounds. Results confirmed the presence of a greater articulatory stability in the production of native vowels in autistic adults. When instructed to imitate artificial vowel-like sounds, the autistic group did not better approximate the targets' acoustic properties relative to neuro-typicals but their performance at reproducing artificial vowels was less variable and influenced to a greater extent by the articulatory properties of their own vocalic space. These findings suggest that the greater articulatory stability observed in autistic adults arises from a lack of flexibility in the production of their own native vowels. The two phonetic tasks are devoid of any pragmatic constraint, which indicates that phonetic inflexibility in autism is partly independent of register selection. LAY SUMMARY: Autistic and neuro-typical adults took part in two tasks: one in which they produced vowels from French, their native tongue, and the other where they imitated unfamiliar vowels. Autistic adults displayed significantly less variation in their production of different French vowels. In imitating unfamiliar vowels, they were more influenced by the way they pronounce French vowels. These results suggest that the atypical speech style, frequently attested in autistic individuals, could stem from an unusually stable pronunciation of speech sounds.

Strategic Deception in Adults with Autism Spectrum Disorder.

Autism Spectrum Disorder (ASD) is often associated with impaired perspective-taking skills. Deception is an important indicator of perspective-taking, and therefore may be thought to pose difficulties to people with ASD (e.g., Baron-Cohen in J Child Psychol Psychiatry 3:1141-1155, 1992). To test this hypothesis, we asked participants with and without ASD to play a computerised deception game. We found that participants with ASD were equally likely-and in complex cases of deception even more likely-to deceive and detect deception, and learned deception at a faster rate. However, participants with ASD initially deceived less frequently, and were slower at detecting deception. These results suggest that people with ASD readily engage in deception but may do so through conscious and effortful reasoning about other people's perspective.

The role of gender in the perception of autism symptom severity and future behavioral development.

Background: Increasing attention is being paid to the higher prevalence of boys with Autism Spectrum Disorder (ASD) and to the implications of this ratio discrepancy on our understanding of autism in girls. One recent avenue of research has focused on caregiver's concern, suggesting that autism might present differently in boys and girls. One unexplored factor related to concerns on child development is whether socio-cultural factors such as gender-related expectations influence the evaluation of symptom severity and predictions about future behavioral development. Methods: The latter concerns were the focus of the present study and were explored by investigating laypeople's judgment of the severity of autism symptoms using an online parent role-playing paradigm, in which participants were asked to rate vignettes depicting the behaviors of a child in different everyday life scenarios. The child's gender and the severity of ASD symptoms were manipulated to examine the effect of gender on the perception of symptom severity. Results: Results suggest that there are no gender differences in perceived symptom severity and associated degree of concern for 5-year-old boys and girls but that there is a gender difference in perceived future atypicality at 15 years old, with boys being rated as more likely to be perceived as atypical by their peers at that age than girls. Conclusions: Investigating parent's cognition about their child's future behavioral development can provide additional information regarding delayed diagnosis of autistic girls.

Brief Report: Acoustic Evidence for Increased Articulatory Stability in the Speech of Adults with Autism Spectrum Disorder.

Subjective impressions of speech delivery in Autism Spectrum Disorder (ASD) as monotonic or over-precise are widespread but still lack robust acoustic evidence. This study provides a detailed acoustic characterization of the specificities of speech in individuals with ASD using an extensive sample of speech data, from the production of narratives and from spontaneous conversation. Syllable-level analyses (30,843 tokens in total) were performed on audio recordings from two sub-tasks of the Autism Diagnostic Observation Schedule from 20 adults with ASD and 20 pairwise matched neuro-typical adults, providing acoustic measures of fundamental frequency, jitter, shimmer and the first three formants. The results suggest that participants with ASD display a greater articulatory stability in vowel production than neuro-typical participants, both in phonation and articulatory gestures.

Referential processing in 3- and 5-year-old children is egocentrically anchored.

An ongoing debate in the literature on language acquisition is whether preschool children process reference in an egocentric way or whether they spontaneously and by-default take their partner's perspective into account. The reported study implements a computerized referential task with a controlled trial presentation and simple verbal instructions. Contrary to the predictions of the partner-specific view, entrained referential precedents give rise to faster processing for 3- and 5-year-old children, independently of whether the conversational partner is the same as in the lexical entrainment phase or not. Additionally, both age groups display a processing preference for the interaction with the same partner, be it for new or previously used referential descriptions. These results suggest that preschool children may adapt to their conversational partner; however, partner-specificity is encoded as low-level auditory-phonological priming rather than through inferences about a partner's perspective.

Selective Pragmatic Impairment in Autism Spectrum Disorder: Indirect Requests Versus Irony.

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.
