Using a Prerequisite Skills Assessment to Identify Optimal Modalities for Mand Training
This study examined the utility of a brief prerequisite assessment in predicting the subsequent effectiveness and rate of acquisition of mand training in each of three response modalities (sign, picture exchange, and vocalizations). Overall, the picture exchange was the most effective and efficient modality for acquiring the targeted mand. The vocal modality was the least effective except when the prerequisite assessment indicated that two-syllable vocal imitation was intact. The implications for selection of response modality for early mand training are discussed.
