Abstract:
Aided language stimulation is an augmented input strategy that facilitates the expressive and
receptive language of persons who use AAC. 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.
