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.

BRANIGAN, Auteur Article en page(s) : p.1929-1941 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/psychology Autistic Disorder Child Humans Imitative Behavior Language Ostracism Affiliation Alignment Autism Conversation Language imitation Index. décimale : PER Périodiques Résumé : In dialogue, speakers tend to imitate, or align with, a partner's language choices. 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.

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.

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.

Titre : Linguistic Tone and Non-Linguistic Pitch Imitation in Children with Autism Spectrum Disorders: A Cross-Linguistic Investigation Type de document : Texte imprimé et/ou numérique Auteurs : Fei CHEN, Auteur ; Candice Chi-Hang CHEUNG, Auteur ; Gang PENG, Auteur Article en page(s) : p.2325-2343 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Child Humans Imitative Behavior Linguistics Pitch Perception Speech Perception Asd Cantonese Imitation Lexical tone Mandarin Non-linguistic pitch Index. décimale : PER Périodiques Résumé : The conclusions on prosodic pitch features in autism spectrum disorders (ASD) have primarily been derived from studies in non-tonal language speakers. 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.

Some of these components may be essential for the intervention to work, while others may be recommended or viewed as helpful but not necessary for the intervention to work. "Recommended" components are often described as "adaptable" because they can be changed to improve fit in different settings where interventions are offered or with different individuals. We need to understand which parts of an intervention are essential (and which are adaptable) when translating interventions from research to community settings, but it is challenging to do this before studying an intervention in the community. This article presents the CORE (COmponents & Rationales for Effectiveness) Fidelity Method-a new method for defining the essential components of evidence-based interventions-and applies it to a case example of Reciprocal Imitation Teaching, an intervention that parents are taught to deliver with their young children with social communication delays. The CORE Fidelity Method involves three steps: (1) gathering information from multiple sources; (2) integrating information from previous research and theory; and (3) drafting a CORE model for ongoing use. The benefits of using the CORE Fidelity Method may include: (1) improving consistency in intervention and research materials to help all providers emphasize the most important skills or strategies; (2) clarifying which parts of the intervention can be adapted; and (3) supporting future research that evaluates which intervention components work and how they work.
