Brief Report: Acoustic Evidence for Increased Articulatory Stability in the Speech of Adults with Autism Spectrum Disorder / M. KISSINE in Journal of Autism and Developmental Disorders, 49-6 (June 2019)

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.

Phonetic Inflexibility in Autistic Adults / M. KISSINE in Autism Research, 14-6 (June 2021)  

Public ISBD [article]  inAutism Research > 14-6 (June 2021) . - p.1186-1196 Titre : Phonetic Inflexibility in Autistic Adults Type de document : Texte imprimé et/ou numérique Auteurs : M. KISSINE, Auteur ; Philippine GEELHAND, Auteur ; M. PHILIPPART DE FOY, Auteur ; B. HARMEGNIES, Auteur ; G. DELIENS, Auteur Article en page(s) : p.1186-1196 Langues : Anglais (eng) Mots-clés : Acoustics  Adult  Autism Spectrum Disorder  Autistic Disorder/complications  Humans  Male  Phonetics  Speech  Speech Acoustics  acoustics  autism  language  phonetic compliance  phonetic inflexibility in autistic adults  prosody Index. décimale : PER Périodiques Résumé : 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.

Selective Pragmatic Impairment in Autism Spectrum Disorder: Indirect Requests Versus Irony / G. 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 et/ou numérique Auteurs : G.

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.

The role of gender in the perception of autism symptom severity and future behavioral development / Philippine GEELHAND in Molecular Autism, 10 (2019)  

Public ISBD [article]  inMolecular Autism > 10 (2019) . - 16 p. Titre : The role of gender in the perception of autism symptom severity and future behavioral development Type de document : Texte imprimé et/ou numérique Auteurs : Philippine GEELHAND, Auteur ; P. BERNARD, Auteur ; O. KLEIN, Auteur ; B. VAN TIEL, Auteur ; M. KISSINE, Auteur Article en page(s) : 16 p. Langues : Anglais (eng) Mots-clés : Adolescence  Caregiver  Concern  Gender bias  Sex ratio  Symptom severity Index. décimale : PER Périodiques Résumé : 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.
