Acquisition of sentence frame discrimination using the iPad™ as a speech generating device in young children with developmental disabilities

This study evaluated the use of the iPad™ and application Proloqu2Go as a speech generating device (SGD) for the acquisition of a tact (labeling) repertoire in three preschool aged children with Autism Spectrum Disorder or developmental delay. Additionally, discrimination between picture icons and sentence frames were investigated. Using a five second time delay, with full physical prompts, participants were taught to label four items using the carrier phrases “I see” and “I have”. Following the acquisition of those frames in isolation, training on discriminating between those frames was introduced. The results indicate that the training procedures were effective for this purpose, thus contributing to the already existing literature on the use of handheld computing devices as SGD.
