Enhanced pitch discrimination in autistic children with unexpected bilingualism / Marie BELENGER ; Inge-Marie EIGSTI ; Mikhail KISSINE in Autism Research, 17-9 (September 2024)  

Public ISBD [article]  inAutism Research > 17-9 (September 2024) . - p.1844-1852 Titre : Enhanced pitch discrimination in autistic children with unexpected bilingualism Type de document : texte imprimé Auteurs : Marie BELENGER, Auteur ; Inge-Marie EIGSTI, Auteur ; Mikhail KISSINE, Auteur Article en page(s) : p.1844-1852 Langues : Anglais (eng) Mots-clés : autism  enhanced auditory perception  language acquisition  low-level processing  screen exposure  unexpected bilingualism Index. décimale : PER Périodiques Résumé : Abstract Some autistic children acquire foreign languages from exposure to screens. Such unexpected bilingualism (UB) is therefore not driven by social interaction, rather, language acquisition appears to rely on less socially mediated learning and other cognitive processes. We hypothesize that UB children may rely on other cues, such as acoustic cues, of the linguistic input. Previous research indicates enhanced pitch processing in some autistic children, often associated with language delays and difficulties in forming stable phonological categories due to sensitivity to subtle linguistic variations. We propose that repetitive screen-based input simplifies linguistic complexity, allowing focus on individual cues. This study hypothesizes that autistic UB children exhibit superior pitch discrimination compared with both autistic and non-autistic peers. From a sample of 46 autistic French-speaking children aged 9 to 16, 12 were considered as UB. These children, along with 45 non-autistic children, participated in a two-alternative forced-choice pitch discrimination task. They listened to pairs of pure tones, 50% of which differed by 3% (easy), 2% (medium), or 1% (hard). A stringent comparison of performance revealed that only the autistic UB group performed above chance for tone pairs that differed, across all conditions. This group demonstrated superior pitch discrimination relative to autistic and non-autistic peers. This study establishes the phenomenon of UB in autism and provides evidence for enhanced pitch discrimination in this group. Acute perception of auditory information, combined with repeated language content, may facilitate UB children's focus on phonetic features, and help acquire a language with no communicative support or motivation.

Exploring Pragmatic Abilities in Sisters of Autistic Individuals: A Methodological Solution to Female Autism Research / Marie BELENGER in Autism Research, 19-1 (January 2026)  

Public ISBD [article]  inAutism Research > 19-1 (January 2026) . - p.e70147 Titre : Exploring Pragmatic Abilities in Sisters of Autistic Individuals: A Methodological Solution to Female Autism Research Type de document : texte imprimé Auteurs : Marie BELENGER, Auteur ; Charlotte DUMONT, Auteur ; Mikhail KISSINE, Auteur Article en page(s) : p.e70147 Langues : Anglais (eng) Mots-clés : adolescence  pragmatics  sex differences  sisters Index. décimale : PER Périodiques Résumé : ABSTRACT Autism is more frequently diagnosed in males than females. One possible explanation for this discrepancy is that autistic females may be overlooked because they show different, subtler signs of autism. For example, sex differences have been reported in pragmatic abilities. However, studying these sex differences is challenging, because diagnosed autistic females may not represent all autistic females?many remaining undiagnosed. To address this issue, our study included adolescent females at increased likelihood for autism: sisters of autistic individuals. Adolescence is a key period when autism-related difficulties often become more visible. We compared the pragmatic abilities of 76 female participants aged between 9 and 16?years old across three groups: autistic, nonautistic, and sisters of diagnosed autistic individuals. Participants completed a semistructured, spoken narrative task, which was analyzed for coherence and fluency. Their caregivers completed several questionnaires to assess both pragmatic abilities and global difficulties. At the group level, caregiver reports indicated an in-between position for sisters: they experienced more pragmatic-related difficulties than nonautistic participants but fewer than autistic participants. Narratives revealed no differences between sisters and nonautistic participants, with one exception: they gave fewer causal explanations of characters' mental states. Individual profiles of sisters revealed a heterogeneous group, varying from no difficulties at all to pragmatic profiles closely resembling those of autistic females.
