Can autism professionals hear the autism diagnosis at a preverbal stage? A first impression study / Marielle WEYLAND in Research in Autism, 132 (April 2026)  

Public ISBD [article]  inResearch in Autism > 132 (April 2026) . - 202844 Titre : Can autism professionals hear the autism diagnosis at a preverbal stage? A first impression study Type de document : texte imprimé Auteurs : Marielle WEYLAND, Auteur ; Pauline MAES, Auteur ; Mikhail KISSINE, Auteur Article en page(s) : 202844 Langues : Anglais (eng) Mots-clés : First impressions  Expert clinician judgements  Autism  Elevated likelihood of autism  Preverbal production  Canonical babbling Résumé : Autism professionals frequently report being able to rapidly detect autism from hearing an autistic individual's vocal production, even before direct interaction. While vocal characteristics can influence diagnostic judgments, it remains unclear how accurate such spontaneous judgements may be and which characteristics of vocalization drive them. To date, there is no research on first impressions of vocalization of young autistic children. Sixty-one autism professionals categorized around two hundred short vocal samples from 9- and 18-month-old children as ‘autistic’ or ‘non-autistic’. The vocal samples were presented in a random order and were either vocalic or canonical babbling productions. Autism professionals showed an overall modest ability to accurately detect which vocalizations were produced by autistic vs non-autistic children. At both 9 and 18 months of age, classification accuracy exceeded chance level for vocalic productions and for canonical babbling productions produced by non-autistic children, whereas accuracy for canonical babbling produced by autistic children did not exceeded chance level and showed a systematic bias toward non-autistic classification. Autism professionals’ first impression based on young children’s vocal productions thus appear only moderately reliable. In typical development, canonical babbling corresponds to a more mature speech acquisition stage than vocalic productions. Accordingly, participating in autism professionals’ classification are probably based more on the perceived maturity of vocalizations sample than on sensitivity to some feature characteristic of autism.

Describing (pre)linguistic oral productions in 3- to 5-year-old autistic children: A cluster analysis / Pauline MAES in Autism, 27-4 (May 2023)  

Public ISBD [article]  inAutism > 27-4 (May 2023) . - p.967-982 Titre : Describing (pre)linguistic oral productions in 3- to 5-year-old autistic children: A cluster analysis Type de document : texte imprimé Auteurs : Pauline MAES, Auteur ; Marielle WEYLAND, Auteur ; Mikhail KISSINE, Auteur Article en page(s) : p.967-982 Langues : Anglais (eng) Mots-clés : autism spectrum disorder,cluster analysis,expressive language,minimally speaking Index. décimale : PER Périodiques Résumé : In many autistic children, speech onset is delayed and expressive language emerges after 3 years of age. We qualitatively and quantitatively describe oral productions of autistic preschoolers, including many non- or minimally speaking, recorded during interactions with a caregiver and with an experimenter. Data clustering on manually coded oral production samples indicates five validated linguistic profiles of oral production in this diverse and inclusive sample (n=59) of 3- to 5-year-old autistic children with highly variable expressive language abilities. These profiles are then compared on a series of demographic (age, socioeconomic status) and psychometric (autism severity, nonverbal and verbal IQ) measures, as well as on additional measures of language (expressive vocabulary, phonetic inventories). Two clusters are composed of speaking autistic children, while the three others comprise non- or minimally speaking children with qualitatively different patterns of vocal productions. The five-profile division suggests that traditional binary division of speaking vs nonspeaking children does not do justice to the complexity of early expressive language in autism.Lay abstractFor most autistic children, spoken language emergence and development happen after the age of 3. Once they start developing and using spoken language, some eventually manage to reach typical levels of language abilities, while others remain minimally speaking into adulthood. It is therefore difficult to consider young autistic preschoolers as a homogeneous group in terms of spoken language levels. In our study, we breakdown a representative and inclusive group of children on the spectrum aged from 3 to 5 into five subgroups that correspond to different linguistic profiles. To do so, we qualitatively described children s (pre)verbal productions elicited during interactions with a parent and with an experimenter. We then used a type of statistical analysis called cluster analysis to group together the children that had a similar expressive (pre)linguistic behavior. Using this analysis, we were able to delineate five linguistic profiles with qualitatively different patterns of vocal production. Two of these profiles are composed of speaking children; the three others are composed of non- or minimally speaking children. Our findings show that traditional binary division of speaking versus nonspeaking autistic children is not precise enough to describe the heterogeneity of early spoken language in young autistic children. They also support the use of qualitative descriptions of vocal productions and speech to accurately document children s level of language, which could, in turn, help design very finely tailored language intervention specific to each child.
