The aim of this study was to compare the acquisition of receptive vocabulary items during implementation of aided language stimulation with a frequency of 40% and 70% respectively. An Adapted Alternating Treatment Design was utilised in this study with six participants. Results revealed that three participants showed the greatest acquisition of target receptive vocabulary in the intervention with a frequency of 70% aided language stimulation. Two participants showed greater acquisition of target receptive vocabulary acquisition in the intervention with a frequency of 40% aided language stimulation. One participant showed equal acquisition of target receptive vocabulary in the intervention with a frequency of 40% and 70% aided language stimulation. The results of the study are discussed in relation to the aims. Finally limitations of the study are discussed and recommendations for future research are made.en© 2019 University of Pretoria.
