Individuals with autism spectrum disorder are impaired in absolute but not relative pitch and duration matching in speech and song imitation / L. WANG in Autism Research, 14-11 (November 2021)  

Public ISBD [article]  inAutism Research > 14-11 (November 2021) . - p.2355-2372 Titre : Individuals with autism spectrum disorder are impaired in absolute but not relative pitch and duration matching in speech and song imitation Type de document : Texte imprimé et/ou numérique Auteurs : L. WANG, Auteur ; P. Q. PFORDRESHER, Auteur ; C. JIANG, Auteur ; F. LIU, Auteur Article en page(s) : p.2355-2372 Langues : Anglais (eng) Mots-clés : Adult  Autism Spectrum Disorder/complications  Child  Humans  Imitative Behavior  Singing  Speech  Voice  Asd  duration  pitch  song  speech  vocal imitation Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) often exhibit atypical imitation. However, few studies have identified clear quantitative characteristics of vocal imitation in ASD. This study investigated imitation of speech and song in English-speaking individuals with and without ASD and its modulation by age. Participants consisted of 25 autistic children and 19 autistic adults, who were compared to 25 children and 19 adults with typical development matched on age, gender, musical training, and cognitive abilities. The task required participants to imitate speech and song stimuli with varying pitch and duration patterns. Acoustic analyses of the imitation performance suggested that individuals with ASD were worse than controls on absolute pitch and duration matching for both speech and song imitation, although they performed as well as controls on relative pitch and duration matching. Furthermore, the two groups produced similar numbers of pitch contour, pitch interval-, and time errors. Across both groups, sung pitch was imitated more accurately than spoken pitch, whereas spoken duration was imitated more accurately than sung duration. Children imitated spoken pitch more accurately than adults when it came to speech stimuli, whereas age showed no significant relationship to song imitation. These results reveal a vocal imitation deficit across speech and music domains in ASD that is specific to absolute pitch and duration matching. This finding provides evidence for shared mechanisms between speech and song imitation, which involves independent implementation of relative versus absolute features. LAY SUMMARY: Individuals with autism spectrum disorder (ASD) often exhibit atypical imitation of actions and gestures. Characteristics of vocal imitation in ASD remain unclear. By comparing speech and song imitation, this study shows that individuals with ASD have a vocal imitative deficit that is specific to absolute pitch and duration matching, while performing as well as controls on relative pitch and duration matching, across speech and music domains.

Autistic children's language imitation shows reduced sensitivity to ostracism / Zoë L. HOPKINS in Journal of Autism and Developmental Disorders, 52-5 (May 2022)

Higher levels of alignment facilitate communication and can be elicited by affiliation goals. Since autistic children have interaction and communication impairments, we investigated whether a failure to display affiliative language imitation contributes to their conversational difficulties. We measured autistic children's lexical alignment with a partner, following an ostracism manipulation which induces affiliative motivation in typical adults and children. While autistic children demonstrated lexical alignment, we observed no affiliative influence on ostracised children's tendency to align, relative to controls. Our results suggest that increased language imitation-a potentially valuable form of social adaptation-is unavailable to autistic children, which may reflect their impaired affective understanding.

Imitation and recognition of facial emotions in autism: a computer vision approach / H. DRIMALLA in Molecular Autism, 12 (2021)  

Public ISBD [article]  inMolecular Autism > 12 (2021) . - 27 p. Titre : Imitation and recognition of facial emotions in autism: a computer vision approach Type de document : Texte imprimé et/ou numérique Auteurs : H. DRIMALLA, Auteur ; Irina BASKOW, Auteur ; B. BEHNIA, Auteur ; S. ROEPKE, Auteur ; I. DZIOBEK, Auteur Article en page(s) : 27 p. Langues : Anglais (eng) Mots-clés : Adult  Autistic Disorder/psychology  Emotions  Facial Expression  Female  Humans  Imitative Behavior  Male  Middle Aged  Recognition, Psychology  Signal Processing, Computer-Assisted  Young Adult  Autism  Automated analysis  Emotion recognition  Imitation Index. décimale : PER Périodiques Résumé : BACKGROUND: Imitation of facial expressions plays an important role in social functioning. However, little is known about the quality of facial imitation in individuals with autism and its relationship with defining difficulties in emotion recognition. METHODS: We investigated imitation and recognition of facial expressions in 37 individuals with autism spectrum conditions and 43 neurotypical controls. Using a novel computer-based face analysis, we measured instructed imitation of facial emotional expressions and related it to emotion recognition abilities. RESULTS: Individuals with autism imitated facial expressions if instructed to do so, but their imitation was both slower and less precise than that of neurotypical individuals. In both groups, a more precise imitation scaled positively with participants' accuracy of emotion recognition. LIMITATIONS: Given the study's focus on adults with autism without intellectual impairment, it is unclear whether the results generalize to children with autism or individuals with intellectual disability. Further, the new automated facial analysis, despite being less intrusive than electromyography, might be less sensitive. CONCLUSIONS: Group differences in emotion recognition, imitation and their interrelationships highlight potential for treatment of social interaction problems in individuals with autism.

Impact of imitation abilities on social communication in autistic children: evidence from an Early Start Denver Model intervention study / Jing LI in Molecular Autism, 16 (2025)

Index. décimale : PER Périodiques Résumé : Imitation is foundational to early social learning, yet autistic children often exhibit significant impairments in imitation, potentially impacting their social communication skills. This study examined the relationship between imitation abilities and social communication in autistic children and evaluated the effectiveness of the Early Start Denver Model (ESDM) intervention. The study included 52 autistic children aged 2-5, divided into an experimental group receiving ESDM intervention and a control group undergoing standard rehabilitation. We assessed the children's imitation and social communication skills before and after the intervention. Results indicated a significant positive correlation between imitation and social communication skills both before and after the intervention. Specifically, various forms of imitation (e.g., vocal, gestural, object-related) were closely linked to different domains of social communication (e.g., expressive communication, joint attention, social skills). Baseline imitation levels and improvements in imitation were significant predictors of enhanced social communication, jointly accounting for over half of the observed improvements in social communication, with imitation improvement being the strongest predictor. Age positively moderated the relationship between imitation and social communication, with older children showing a stronger impact of imitation on social communication. Although these effects were evident across groups, the ESDM group showed greater gains in imitation skills compared to the control group. However, we did not find evidence of an intervention effect on social communication skills. This study underscores the critical role of imitation in the social communication development of autistic children. These findings support the enhancement of imitation skills in early interventions for autistic children, highlighting the effectiveness of ESDM in fostering imitation abilities.

Linguistic Tone and Non-Linguistic Pitch Imitation in Children with Autism Spectrum Disorders: A Cross-Linguistic Investigation / Fei CHEN in Journal of Autism and Developmental Disorders, 52-5 (May 2022)

This cross-linguistic study evaluated the performance of imitating Cantonese lexical tones and their non-linguistic (nonspeech) counterparts by Cantonese- and Mandarin-speaking children with and without ASD. Acoustic analyses showed that, compared with typically developing peers, children with ASD exhibited increased pitch variations when imitating lexical tones, while performed similarly when imitating the nonspeech counterparts. Furthermore, Mandarin-speaking children with ASD failed to exploit the phonological knowledge of segments to improve the imitation accuracy of non-native lexical tones. These findings help clarify the speech-specific pitch processing atypicality and phonological processing deficit in tone-language-speaking children with ASD.
