The purpose of the study was to compare picture exchange (PE) and an iPad™ –based speech generating device (SGD) in teaching mands to five preschool boys diagnosed with autism. Participants’ preferences for each device were assessed following training. Three participants met mastery criterion for mands using the SGD more quickly, while two participants met mastery criterion for mands using PE more readily. However, the overall rate of independent manding across training and maintenance was higher for four participants using the SGD. Four participants demonstrated a clear preference for the SGD device and one for PE. Results are consistent with previous research showing that acquisition of alternative communication modalities varies across children with autism, and supports the use of assessment to determine modality preference.
