The purpose of this study was to evaluate the effects of generic icons and individualized icons on a speech generating device (SGD) on the independence of mands and assess preference for icon type. The researcher used a single-subject alternating treatment design to compare icon types with one participant with a limited mand repertoire. Two preference assessments were conducted to determine edibles for mand training. The intervention consisted of mand training with physical prompting and alternating icon types. Results showed that there was no difference in independence of mands based on icon-type. After mand training sessions, the researcher conducted a concurrent operant preference assessment to determine if one icon-type was more preferred. Results demonstrated a clear preference for one icon-type.
