While face scanning is a dynamic process, the way autistic children distribute their attention between the eyes and mouth of their interlocutor is usually analyzed by averaging the proportion of time spent looking either on the eyes or the mouth over the whole duration of stimulus presentation. Method In this study, instead, we focused on the temporal distribution of visual attention between the eyes and mouth of adult faces in 58 autistic and 61 typically developing (TD) children. Participants? eye movements were recorded as they were freely watching videos of faces of silent and speaking adults. We explored attention to the eyes and mouth with fine-grained analyses of the temporal trajectory of fixations on the two regions using generalized additive mixed effects models. Results These analyses revealed that both groups started their observation of speaking faces on the eyes and shifted to the mouth as the actor started speaking. However, TD, but not autistic children then slowly shifted their attention back to the eyes. Conclusions Rigorous analyses of how autistic children modulate their visual attention between key social features of the face over time may provide more accurate descriptions of their face scanning abilities.

Ten children with autism were videotaped in naturalistic conditions. Four grammatical sentence types were distinguished: imperative, declarative, interrogative and sub-sentential. For each category, the proportion of requests complied with significantly exceeded the proportion of requests not complied with, and no difference across categories was found. These results show that children with autism do not rely exclusively on the linguistic form to interpret an utterance as a request.

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 et/ou numérique 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.

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 et/ou numérique 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.

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 et/ou numérique 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.
