Historically, given the exorbitant costs associated with its use, high capability speech-generating devices (SGDs) were often an impractical option as an augmentative and alternative communication (AAC) system for young children with autism spectrum disorder (ASD). However, since the release of the iPod Touch in 2007 and the subsequent release of the iPad in 2011, the field of ASD intervention has seen a rapid shift in the use of SGDs as an AAC system. These highly sought after consumer products are more popular than ever; however, to date there has not been a clear and evidenced-based system for their use. The purpose of this paper is to present the current empirical trends in the use of the iPad and application Proloquo2Go as an SGD for verbal operant training in young children with ASD and to present implications for use of the SGD in applied behavior analytic treatment of ASD. Additionally, implications for future research and practice are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved)
