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.

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.

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.

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.

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.

Strategic Deception in Adults with Autism Spectrum Disorder / Bob VAN TIEL in Journal of Autism and Developmental Disorders, 51-1 (January 2021)

Deception is an important indicator of perspective-taking, and therefore may be thought to pose difficulties to people with ASD (e.g., Baron-Cohen in J Child Psychol Psychiatry 3:1141-1155, 1992). To test this hypothesis, we asked participants with and without ASD to play a computerised deception game. We found that participants with ASD were equally likely-and in complex cases of deception even more likely-to deceive and detect deception, and learned deception at a faster rate. However, participants with ASD initially deceived less frequently, and were slower at detecting deception. These results suggest that people with ASD readily engage in deception but may do so through conscious and effortful reasoning about other people's perspective.
