Assessment of the communicative and coordination skills of children with Autism Spectrum Disorders and typically developing children using social signal processing / Emilie DELAHERCHE in Research in Autism Spectrum Disorders, 7-6 (June 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-6 (June 2013) . - p.741-756 Titre : Assessment of the communicative and coordination skills of children with Autism Spectrum Disorders and typically developing children using social signal processing Type de document : Texte imprimé et/ou numérique Auteurs : Emilie DELAHERCHE, Auteur ; Mohamed CHETOUANI, Auteur ; Fabienne BIGOURET, Auteur ; Jean XAVIER, Auteur ; Monique PLAZA, Auteur ; David COHEN, Auteur Article en page(s) : p.741-756 Langues : Anglais (eng) Mots-clés : Social signal processing  Coordination  Imitation  Autism spectrum disorder Index. décimale : PER Périodiques Résumé : To cooperate with a partner, it is essential to communicate by sharing information through all available avenues, including hand gestures, gazes, head gestures and naturally, speech. In this paper, we compare the communicative and coordination skills of children with typical development to those of children with Autism Spectrum Disorders (ASDs) in cooperative joint action tasks. Communicative skills were assessed using a pragmatic annotation grid. Coordination skills were assessed based on automatically extracted features that characterize interactive behavior (turn-taking, synchronized gestures). First, we tested the performance of the interactive features when discriminating between the two groups of children (typical vs. ASD). Features characterizing the gestural rhythms of the therapist and the duration of his gestural pauses were particularly accurate at discriminating between the two groups. Second, we tested the ability of these features for the continuous classification problem of predicting the developmental age of the child. The duration of the verbal interventions of the therapist were predictive of the age of the child in all tasks. Furthermore, more features were predictive of the age of the child when the child had to lead the task. We conclude that social signal processing is a promising tool for the study of communication and interaction in children with ASD because we showed that therapists adapt differentially in three different tasks according to age and clinical status.

Differential language markers of pathology in Autism, Pervasive Developmental Disorder Not Otherwise Specified and Specific Language Impairment / Julie DEMOUY in Research in Autism Spectrum Disorders, 5-4 (October-December 2011)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 5-4 (October-December 2011) . - p.1402-1412 Titre : Differential language markers of pathology in Autism, Pervasive Developmental Disorder Not Otherwise Specified and Specific Language Impairment Type de document : Texte imprimé et/ou numérique Auteurs : Julie DEMOUY, Auteur ; Monique PLAZA, Auteur ; Jean XAVIER, Auteur ; Fabien RINGEVAL, Auteur ; Mohamed CHETOUANI, Auteur ; Didier PERISSE, Auteur ; Dominique CHAUVIN, Auteur ; Sylvie VIAUX, Auteur ; Bernard GOLSE, Auteur ; David COHEN, Auteur ; Laurence ROBEL, Auteur Année de publication : 2011 Article en page(s) : p.1402-1412 Langues : Anglais (eng) Mots-clés : Autism  Specific Language Impairment  Pervasive Developmental Disorder Not Otherwise Specified  Language  Prosody Index. décimale : PER Périodiques Résumé : Language impairment is a common core feature in Pervasive Developmental Disorders (PDD) and Specific Language Impairment (SLI). Many studies have tried to define the specific language profiles of these disorders, some claiming the existence of overlaps, and others conceiving of them as separate categories. Fewer have sought to determine whether and how PDD-NOS language profile, including prosody, differs from those of Autistic Disorder (AD) and SLI. Here, 12 children with AD (mean age 9.75; sd 3.5), 10 with PDD-NOS (mean age 9.83; sd 2.17), and 13 children with SLI (mean age 9.17; sd 3.9) matched for age, sex and academic skills were explored for both receptive and expressive language skills. Prosody was also assessed with an intonation imitation task analyzed through automatic speech processing and compared to 70 typical developing controls matched for age and sex. A similar delay in phonology and vocabulary was observed in the three groups as were significant but variable differences between the groups in syntax, pragmatics and prosody. SLI showed correlations between chronological age and raw scores in all language tasks, while AD and PDD-NOS did not. Furthermore, SLI showed correlation within all raw scores in language tasks. Most of those correlations were also found in PDD-NOS but not in AD. In conclusion, these findings support the hypothesis that language skills in AD and SLI rely on different mechanisms, while PDD-NOS show an intermediate profile sharing some characteristics of both AD and SLI. They also suggest that expressive syntax, pragmatic skills and some intonation features could be considered as language differential markers of pathology, challenging the DSM-V proposal of broad criteria.

Have information and communication technologies research for neurodevelopmental disorders improved overtime? A systematic meta-review / Carlotta BETTENCOURT in Research in Autism Spectrum Disorders, 118 (October 2024)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 118 (October 2024) . - 102483 Titre : Have information and communication technologies research for neurodevelopmental disorders improved overtime? A systematic meta-review Type de document : Texte imprimé et/ou numérique Auteurs : Carlotta BETTENCOURT, Auteur ; Salvatore ANZALONE, Auteur ; Mohamed CHETOUANI, Auteur ; David COHEN, Auteur ; Charline GROSSARD, Auteur Article en page(s) : 102483 Langues : Anglais (eng) Mots-clés : Metareview  ICT  Neurodevelopmental disorders  Design  Methodology Index. décimale : PER Périodiques Résumé : Background The significant increase of Information Communication Technologies (ICTs) use for individuals with Neurodevelopmental Disorders (NDD) has created an urgent need to examine the implications of both the design and the research methodologies used to study them. Methods We searched four databases (PubMed, IEEXplore, Scopus, and ACM Digital Library) to find relevant reviews on clinical applications of ICTs with individuals with NDD. We extracted all studies (n = 1879) from 301 reviews, and classified them into categories: robots, serious games (SG), video modeling (VM), Augmentative and Alternative Communication (AAC). We randomly assessed 182 studies (45 per ICT category) stratified by years of publication using the Connolly methodology scale and design ICT inventory (DICTI). We also described the best papers per ICT (most cited or highest impact factor journals). Results Our assessments have indicated that the overall research methodology quality of ICT studies is poor. Serious Games (SG) studies have the best research methodology and ICT design quality scores. Studies on robots, Augmentative and Alternative Communication (AAC), and video modeling (VM) have shown improved research methodology over the years, though only SG design shown improvement consistently. Autism is the most prevalent NDD in terms of clinical focus in ICT therapeutic and educational interventions. Currently, no ICT has been approved as a prescription treatment in NDD, with the notable exception of EndeavorRx?, a SG for Attention Deficit Hyperactivity Disorder (ADHD). The literature also emphasizes that meeting the main research methodology criteria is essential for evidence-based medicine, Personalization, adaptability, positive feedback, human interaction and affordability are among the most important features to take into consideration in ICT design for NDD. Conclusion The review highlights the need for higher-quality studies, user-friendly technologies, personalization, positive feedback, and accessibility. ICTs are not detrimental to learning and demonstrate potential benefits for individuals with NDD. However, more evidence-based studies are needed to reach treatment prescription recommendation.

How children with autism spectrum disorder behave and explore the 4-dimensional (spatial 3D#xa0;+#xa0;time) environment during a joint attention induction task with a robot / Salvatore Maria ANZALONE in Research in Autism Spectrum Disorders, 8-7 (July 2014)

We built a system that employed a Nao robot and a perception system based on a RGB-D sensor (Kinect) to capture social engagement cues. A JA induction experiment was performed in which children with ASD (N = 16) and matched TD children (N = 16) had a 3-min interaction with the robot or with a therapist. Nao induced JA by gazing; by gazing and pointing; and by gazing, pointing and vocalizing at pictures. Both groups of children performed well with the therapist. However, with Nao, both groups had lower JA scores, and the children with ASD had a significantly lower score than the TD children. We found that (i) multimodal JA induction was more efficient in both groups; (ii) the 3D spatial world gaze exploration showed less accuracy; and (iii) the trunk position in ASD showed less stability in the 4 dimensions compared to TD controls. We conclude that, in ASD, JA skill depends on the interaction partner, and implies a higher motor and cognitive cost.

What studies of family home movies can teach us about autistic infants: A literature review / Catherine SAINT-GEORGES in Research in Autism Spectrum Disorders, 4-3 (July-September 2010)

Out of 41 original reports found since 1975, we retained 18 studies (317 films, maximum), sorted according to their methodological design using a quality grid. In the first 2 years of life, signs that differentiated children with ASD from children with developmental delays were as follows: less of a response to their name, less looking at others, lower eye contact quality and quantity, less positive facial expression and intersubjective behaviors (e.g., showing shared attention). Studies focusing on regression confirmed the clinical validity of the phenomena. We conclude that findings from home movies studies along with prospective studies have created the bases for identification of infants and toddlers at risk of developing ASD before the 18–24-month period, despite early diagnosis of autism remains a complex challenge.
