Efficacy of a novel augmentative and alternative communication system in promoting requesting skills in young children with Autism Spectrum  Disorder in India: A pilot study / Sudha SRINIVASAN in Autism & Developmental Language Impairments, 7 (January-December 2022)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 7 (January-December 2022) Titre : Efficacy of a novel augmentative and alternative communication system in promoting requesting skills in young children with Autism Spectrum  Disorder in India: A pilot study Type de document : Texte imprimé et/ou numérique Auteurs : Sudha SRINIVASAN, Auteur ; Siddhi PATEL, Auteur ; Avadhut KHADE, Auteur ; Gaganjot BEDI, Auteur ; Jyoti MOHITE, Auteur ; Ajanta SEN, Auteur ; Ravi POOVAIAH, Auteur Langues : Anglais (eng) Mots-clés : Augmentative and alternative communication  autism spectrum disorders  communication and language  requesting skills  culturally-valid AAC intervention Index. décimale : PER Périodiques Résumé : Background & aims: The study assessed the efficacy of a novel, child-friendly, socio-culturally sensitive, icon-based Augmentative and Alternative Communication (AAC) system called Jellow Communicator, in teaching requesting skills to young children with Autism Spectrum Disorder (ASD) in a special school in Mumbai, India. Jellow is a comprehensive AAC system with a lexicon and pictorial library designed using a participatory, user-centric design process. The content of Jellow has been developed bearing in mind the socio-cultural and linguistic diversity of India. Jellow is available in low-tech (flashcards, booklet) and high-tech (Android and iOS app and desktop application) versions. Methods: The quasi-experimental longitudinal study involved seventeen 3.5 “12-year-old children with ASD with communication challenges. Children were taught to use the Jellow AAC system to request for preferred items, as part of their regular speech therapy sessions. Each child received one-on-one training sessions with a licensed speech therapist twice a week over a 3-month duration, with each session lasting around 20 “30 min. A systematic training protocol adapted from the original Picture Exchange Communication System (PECS) was developed to train children to use the Jellow system, progressing from flashcards to the app version of Jellow. Behavioral training strategies such as modeling, least-to-most prompting, differential reinforcement, and behavior chain interruption were used to facilitate requesting behaviors. The speech therapist assessed children’s developmental level across multiple domains at pretest and posttest. We coded 3 videos per child, i.e., one early, one mid, and one late training session each, to assess changes in children’s stage of communication, spontaneous requesting abilities, level of attention during training trials, and average time to completion for requesting trials. In addition, caregivers filled out questionnaires to assess training-related changes in children’s adaptive functioning levels as well as the psychosocial impact of the Jellow AAC system on children’s quality of life. Results: Children significantly improved their stage of communication, and a majority of children transitioned from flashcards to using the Jellow app to request for preferred items. Children also increased the proportion of spontaneous requests over the course of training. Caregivers reported a positive perceived psychosocial impact of the Jellow AAC system on their child’s self-esteem, adaptability, and competence. Conclusions: The findings from our pilot study support the use of the novel, socio-culturally adapted, Jellow Communicator AAC system for teaching requesting skills to young children with ASD who use multiple communication modalities. Future studies should replicate our findings with a larger group of participants using a randomized controlled trial design. Implications: This is the first experimental study to systematically assess the effects of an indigenously-developed comprehensive AAC system adapted to the sociocultural and linguistic landscape of India. Our study results provide support for the use of the cost-effective Jellow Communicator AAC system in facilitating requesting skills in children with ASD who use multiple communication modalities. Clinicians can use low-tech and high-tech versions of Jellow to promote communication skills in children with ASD.

Impaired praxis in gesture imitation by deaf children with autism spectrum disorder / Aaron SHIELD in Autism & Developmental Language Impairments, 2 (January-December 2017)  

Public ISBD [article]  inAutism & Developmental Language Impairments > 2 (January-December 2017) Titre : Impaired praxis in gesture imitation by deaf children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Aaron SHIELD, Auteur ; Krista KNAPKE, Auteur ; Morgan HENRY, Auteur ; Sudha SRINIVASAN, Auteur ; Anjana N. BHAT, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background and aimsPraxis, the ability to plan and execute a series of gestures or motor sequences, is impaired in individuals with autism spectrum disorder. In this paper, we present the first study of praxis during a gesture imitation task in a unique population of children with autism spectrum disorder: deaf children who have been exposed to American Sign Language from birth by their Deaf parents. Lifelong exposure to sign language in deaf individuals entails practice with gesture imitation. We ask if deaf, signing children with autism spectrum disorder present with praxis impairments similar to those reported in the literature for hearing children with autism spectrum disorder not exposed to sign.MethodsThirty deaf children of Deaf parents (16 typically developing and 14 with autism spectrum disorder), matched for chronological and mental age, were tested on a simple gesture imitation task. Children were asked to imitate 24 gestures performed by an adult model on a laptop computer that varied along dimensions of movement type (16 trials) and palm orientation direction (eight trials). Data were coded for nine praxis parameters (five formation parameters and four manner parameters) and three timing measures.ResultsResults showed that the deaf children with autism spectrum disorder produced more errors than the typically developing deaf children on six of the nine praxis dimensions (hand orientation, final orientation, modulation, directness, pace, and overflow) and were more impaired on manner parameters than formation parameters, suggesting underlying deficits in motor control/coordination leading to dyspraxia. Praxis scores were strongly related to severity of autism spectrum disorder symptoms and receptive sign language scores.ConclusionsWe thus find evidence that praxis is impaired in deaf, signing children with autism spectrum disorder, despite lifelong exposure to a gestural language and extensive practice with gesture imitation.ImplicationsOur findings suggest that interventions targeted toward enhancing praxis and coordination of finger and hand movements could help facilitate language development in children with autism spectrum disorder.

Index. décimale : PER Périodiques Résumé : The COVID-19 pandemic has caused disruption in F2F healthcare delivery and neuroimaging research, especially when involving vulnerable populations such as children with autism spectrum disorder. Given the easy access to multiple video conferencing platforms, many healthcare services have moved to an online delivery format (i.e. telehealth). It is important to monitor the behavioral and neural effects of telehealth interventions and resume neuroimaging research while adopting public health safety protocols to control the risk of COVID-19 transmission. We summarize existing safety protocols and our own experience from in-person functional near-infrared spectroscopy neuroimaging data collection (on-site, at home, and in outdoor settings), as well as potential opportunities of using online data sharing and low-cost, remote neuroimaging/electrophysiological techniques to continue brain research during the pandemic.

The Effect of Robot-Child Interactions on Social Attention and Verbalization Patterns of Typically Developing Children and Children With Autism Between 4 and 8 Years / Sudha SRINIVASAN in Autism - Open Access, 3-2 (September 2013)  

Public ISBD [article]  inAutism - Open Access > 3-2 (September 2013) . - 7 p. Titre : The Effect of Robot-Child Interactions on Social Attention and Verbalization Patterns of Typically Developing Children and Children With Autism Between 4 and 8 Years Type de document : Texte imprimé et/ou numérique Auteurs : Sudha SRINIVASAN, Auteur ; Anjana N. BHAT, Auteur Année de publication : 2013 Article en page(s) : 7 p. Langues : Anglais (eng) Mots-clés : Robots  Social  Attention  Imitation  Verbalization  Communication  Autism  Children Index. décimale : PER Périodiques Résumé : 1.1 Background: There is anecdotal evidence for the use of robots to facilitate prosocial behaviors such as joint attention and verbalization in children with Autism Spectrum Disorders (ASDs). However, there have been no normative data in typically developing children to evaluate the effects of robot-child interactions on social and communication skills. 1.2 Objectives: The aim of our study was to evaluate the changes in social attention and verbalization skills of 15 typically developing (TD) children using a structured 8-session imitation protocol within a robot-adult-child context. We further extended this imitation protocol to two children with ASDs. 1.3 Methods: Pretest, session1, session 4, session 8, and posttest sessions were coded for attention patterns and the duration of verbalization of the children. 1.4 Results: TD children directed maximum attention towards the robot during training; however, they were bored with the limited repertoire of the robot over time. The training context also facilitated spontaneous verbalization between the child and the trainer. The context of robot-child interactions also afforded social attention and spontaneous verbalization in both children with ASDs. 1.5 Conclusions: Our findings suggest that robot-child interactions may be an enjoyable context for TD children as well as children with ASDs. Our future studies will rigorously examine the use of engaging, robot-child interaction contexts for facilitating social communication skills in children with ASDs.
