Assessing the Utility of a Virtual Environment for Enhancing Facial Affect Recognition in Adolescents with Autism / Esubalew BEKELE in Journal of Autism and Developmental Disorders, 44-7 (July 2014)

Titre : Assessing the Utility of a Virtual Environment for Enhancing Facial Affect Recognition in Adolescents with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Esubalew BEKELE, Auteur ; Julie CRITTENDON, Auteur ; Zhi ZHENG, Auteur ; Amy SWANSON, Auteur ; Amy WEITLAUF, Auteur ; Zachary WARREN, Auteur ; Nilanjan SARKAR, Auteur Article en page(s) : p.1641-1650 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Virtual reality Facial expressions Adaptive systems Index. décimale : PER Périodiques Résumé : Teenagers with autism spectrum disorder (ASD) and age-matched controls participated in a dynamic facial affect recognition task within a virtual reality (VR) environment. Participants identified the emotion of a facial expression displayed at varied levels of intensity by a computer generated avatar. The system assessed performance (i.e., accuracy, confidence ratings, response latency, and stimulus discrimination) as well as how participants used their gaze to process facial information using an eye tracker. Participants in both groups were similarly accurate at basic facial affect recognition at varied levels of intensity. Despite similar performance characteristics, ASD participants endorsed lower confidence in their responses and substantial variation in gaze patterns in absence of perceptual discrimination deficits. These results add support to the hypothesis that deficits in emotion and face recognition for individuals with ASD are related to fundamental differences in information processing. We discuss implications of this finding in a VR environment with regards to potential future applications and paradigms targeting not just enhanced performance, but enhanced social information processing within intelligent systems capable of adaptation to individual processing differences.

Titre : Brief Report: Evaluation of an Intelligent Learning Environment for Young Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Zhi ZHENG, Auteur ; Zachary WARREN, Auteur ; Amy WEITLAUF, Auteur ; Qiang FU, Auteur ; Huan ZHAO, Auteur ; Amy SWANSON, Auteur ; Nilanjan SARKAR, Auteur Article en page(s) : p.3615-3621 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Social communication Adaptive systems Early identification Index. décimale : PER Périodiques Résumé : Researchers are increasingly attempting to develop and apply innovative technological platforms for early detection and intervention of autism spectrum disorder (ASD). This pilot study designed and evaluated a novel technologically-mediated intelligent learning environment with relevance to early social orienting skills. The environment was endowed with the capacity to administer social orienting cues and adaptively respond to autonomous real-time measurement of performance (i.e., non-contact gaze measurement). We evaluated the system with both toddlers with ASD (n = 8) as well as typically developing infants (n = 8). Children in both groups were able to ultimately respond accurately to social prompts delivered by the technological system. Results also indicated that the system was capable of attracting and pushing toward correct performance autonomously without user intervention.
