Autistic adults display different verbal behavior only in mixed-neurotype interactions: Evidence from a referential communication task / Philippine GEELHAND in Autism, 29-5 (May 2025)  

Public ISBD [article]  inAutism > 29-5 (May 2025) . - p.1129-1142 Titre : Autistic adults display different verbal behavior only in mixed-neurotype interactions: Evidence from a referential communication task Type de document : texte imprimé Auteurs : Philippine GEELHAND, Auteur ; Fanny PAPASTAMOU, Auteur ; Solène JASPARD, Auteur ; Mikhail KISSINE, Auteur Article en page(s) : p.1129-1142 Langues : Anglais (eng) Mots-clés : neurotype (mis)match  oral versus written language  referential communication Index. décimale : PER Périodiques Résumé : Recent accounts of social difficulties in autism suggest that autistic and non-autistic individuals mutually misunderstand each other. This assumption aligns with findings that mixed-neurotype interactions are less efficient than same-neurotype interactions. However, it remains unclear whether different outcomes between mixed- and same-neurotype interactions are due to contact with a different neurotype or to inherently different communication styles, specific to each neurotype. A total of 134 adult participants were divided into three same-sex dyad types: 23 autistic dyads, 23 non-autistic dyads, and 21 mixed-neurotype dyads. Participants were unaware of their partner?s neurotype. Dyads completed an online referential communication task where a "Director" guides a "Matcher" to rearrange abstract images, using both written (chat) and oral (microphone, no video) communication modes. Interaction outcome measures were task duration and verbosity of the Director. Across both communication modes, non-autistic dyads completed the task faster than autistic and mixed dyads, indicating that dyads with at least one autistic partner were generally slower. Notably, in mixed dyads, autistic Directors were more verbose than non-autistic Directors across both communication modes. These results, in conjunction with partners' unawareness of each other?s neurotype, suggest that even in the absence of non-verbal cues neurotype mismatch triggers autistic adults to display different verbal behavior.Lay abstract Recent research shows that in conversations, both participants influence the outcome. More specifically, conversations do not go as smoothly when autistic and non-autistic people talk together compared to when people of the same neurotype (either all autistic or all non-autistic) talk to each other. In studies finding a "same-neurotype communicative advantage", interaction partners knew about each other?s neurotype. Because of this methodological choice, it is unclear whether mixed-neurotype interactions go less smoothly because participants knew they were interacting with a different neurotype or because each neurotype really has a distinct communication style. In our study, 134 adults were grouped into same-sex pairs: 23 autistic, 23 non-autistic, and 21 mixed-neurotype pairs. The pairs did not know if the other person was autistic or not. They completed an online task where the "Director" instructs the "Matcher" to reorder abstract pictures. Pairs did this task in two ways: by typing in a live chat and by speaking into a microphone without video. The study looked at how long the task took and how much the Director talked/wrote. Results showed that non-autistic pairs were faster to complete the task than autistic pairs and mixed pairs, meaning pairs with at least one autistic person were slower in general to complete the task. Interestingly, in mixed pairs, only autistic Directors produced more words than non-autistic Directors, in both typing and speaking. These findings suggest that even without knowing about their partner?s neurotype and seeing/hearing their partner, autistic adults communicate differently when they interact with a non-autistic person.

Judgments of spoken discourse and impression formation of neurotypical and autistic adults / Philippine GEELHAND in Research in Autism Spectrum Disorders, 82 (April 2021)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 82 (April 2021) . - 101742 Titre : Judgments of spoken discourse and impression formation of neurotypical and autistic adults Type de document : texte imprimé Auteurs : Philippine GEELHAND, Auteur ; Fanny PAPASTAMOU, Auteur ; Gaétane DELIENS, Auteur ; Mikhail KISSINE, Auteur Article en page(s) : 101742 Langues : Anglais (eng) Mots-clés : Autism  First impressions  Spoken discourse  Adults Index. décimale : PER Périodiques Résumé : Background Studies on impression formation in Autism Spectrum Disorder (ASD) have suggested that both ASD and neurotypical (NT) individuals extract paralinguistic cues (e.g., vocal and facial expressions) from brief extracts of social behaviors to form less favorable impressions of the personality traits of ASD individuals than of their NT peers. Yet, discourse studies in ASD have also suggested that there are specific linguistic features (e.g., conjunctions) that can distinguish the speech of ASD individuals from that of NT individuals. This study investigates whether naïve participants with and without autism can perceive discourse features previously identified as characteristic of ASD speech, based on a single exposure to conversation extracts. Methods A cross-design rating experiment was created whereby a group of ASD and NT adults (blind to diagnosis information) rated audio recordings involving ASD and NT speakers. Rating participants evaluated the recordings using a Likert scale targeting impressions of discourse features. Results ASD and NT Raters behaved similarly on the ratings of discourse features; evaluating the speech of ASD Speakers less favorably than those of NT Speakers. Conclusion Our results extend previous findings by showing that linguistic cues also lead to less favorable impressions of the discourse of ASD Speakers, and this from both the perspective of NT and ASD Raters.

Predictive Processing During Cue-Outcome Associative Learning in Autistic Children / Fanny PAPASTAMOU in Journal of Autism and Developmental Disorders, 55-10 (October 2025)

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.

Selective Pragmatic Impairment in Autism Spectrum Disorder: Indirect Requests Versus Irony / Gaétane DELIENS in Journal of Autism and Developmental Disorders, 48-9 (September 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-9 (September 2018) . - p.2938-2952 Titre : Selective Pragmatic Impairment in Autism Spectrum Disorder: Indirect Requests Versus Irony Type de document : texte imprimé Auteurs : Gaétane DELIENS, Auteur ; Fanny PAPASTAMOU, Auteur ; Nicolas RUYTENBEEK, Auteur ; Philippine GEELHAND, Auteur ; Mikhail KISSINE, Auteur Article en page(s) : p.2938-2952 Langues : Anglais (eng) Mots-clés : Autism  Communication  Executive function  Eye-tracking  Indirect speech acts  Irony  Pragmatics  Request  Social motivation Index. décimale : PER Périodiques Résumé : 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.
