This article reports the results of a meta-analysis of technology-based intervention studies for children with autism spectrum disorders. We conducted a systematic review of research that used a pre-post design to assess innovative technology interventions, including computer programs, virtual reality, and robotics. The selected studies provided interventions via a desktop computer, interactive DVD, shared active surface, and virtual reality. None employed robotics. The results provide evidence for the overall effectiveness of technology-based training. The overall mean effect size for posttests of controlled studies of children with autism spectrum disorders who received technology-based interventions was significantly different from zero and approached the medium magnitude, d = 0.47 (confidence interval: 0.08-0.86). The influence of age and IQ was not significant. Differences in training procedures are discussed in the light of the negative correlation that was found between the intervention durations and the studies' effect sizes. The results of this meta-analysis provide support for the continuing development, evaluation, and clinical usage of technology-based intervention for individuals with autism spectrum disorders.

Innovative technology-based interventions for autism spectrum disorders: A meta-analysis

In the past decade there has been a rapid advance in the use of virtual reality (VR) technologies for leisure, training and education. VR is argued to offer particular benefits for children on the autism spectrum, chiefly because it can offer simulations of authentic real-world situations in a carefully controlled and safe environment. Given the real world social difficulties experienced by children on the spectrum, this technology has therefore been argued to offer distinct advantages and benefits for social and life skills training compared to other approaches. Whilst there has been some progress in testing the relevance and applicability of VR for children on the autism spectrum in educational contexts, there remains a significant challenge in developing robust and usable technologies that can really make a difference in real world classrooms. This article considers the evidence that has been published over the past 10 years to assess how the potential of VR has been explored in practice and reflect on...

State-of-the-art of virtual reality technologies for children on the autism spectrum

Major advances in multimedia computer technology over the past decades have made sophisticated computer games readily available to the public. This, combined with the observation that most children, including those with autism spectrum disorders (ASD), show an affinity to computers, has led researchers to recognize the potential of computer technology as an effective and efficient tool in research and treatment. This paper reviews the use of computer-assisted technology (CAT), excluding strictly internet-based approaches, to enhance social, communicative, and language development in individuals with ASD by dividing the vast literature into four main areas: language, emotion recognition, theory of mind, and social skills. Although many studies illustrate the tremendous promise of CAT to enhance skills of individuals with ASD, most lack rigorous, scientific assessment of efficacy relative to non-CAT approaches.

Use of computer-assisted technologies (CAT) to enhance social, communicative, and language development in children with autism spectrum disorders.

A comprehensive review of the literature was conducted for articles published between 1993 and 2012 to determine the degree to which technology-based interventions can be considered an evidence-based practice to teach academic skills to individuals with Autism Spectrum Disorder (ASD). Criteria developed by Horner et al. (Except Child 71:165–178, 2005) and Gersten et al. (Except Child 71:149–164, 2005) were used to determine the quality of single-subject research studies and group experimental research studies respectively. A total of 25 studies met inclusion criteria. Of these studies, only three single-subject studies and no group studies met criteria for quality or acceptable studies. Taken together, the results suggest that practitioners should use caution when teaching academic skills to individuals with ASD using technology-based interventions. Limitations and directions for future research are discussed.

A Review of Technology-Based Interventions to Teach Academic Skills to Students with Autism Spectrum Disorder

The purpose of this review is to provide a systematic analysis of studies involving the use of computer-based interventions (CBI) to teach communication skills to children with autism spectrum disorders (ASD). This review evaluates intervention outcomes, appraises the certainty of evidence, and describes software and system requirements for each included study. This review has three main aims: (a) to evaluate the evidence-base regarding CBI, (b) to inform and guide practitioners interested in using CBI, and (c) to stimulate and guide future research aimed at improving the efficiency and effectiveness of CBI in communication for individuals with ASD. Results suggest that CBI should not yet be considered a researched-based approach to teaching communication skills to individuals with ASD. However, CBI does seem a promising practice that warrants future research.

Use of Computer-Based Interventions to Teach Communication Skills to Children with Autism Spectrum Disorders: A Systematic Review.

A computer-animated tutor, Baldi, has been successful in teaching vocabulary and grammar to children with autism and those with hearing problems. The present study assessed to what extent the face facilitated this learning process relative to the voice alone. Baldi was implemented in a Language Wizard/Tutor, which allows easy creation and presentation of a vocabulary lesson involving the association of pictures and spoken words. The lesson plan included both the receptive identification of pictures and the production of spoken words. A within-subject design with five children with autism followed an alternating treatment in which each child continuously learned to criterion sets of words with and without the face. The rate of learning was significantly faster and the retention was better with the face. The research indicates that at least some children with autism benefit from the face in learning new language within an automated program.
