Further Demonstrations of Individual Preference among Mand Modalities during Functional Communication Training.

Previous research related to functional communication training has demonstrated its effectiveness across various communication modalities. Additionally, at least one study has demonstrated that, while the intervention can be effective across various communication modalities, individual participants demonstrate a preference among available communication modalities (indicated by response allocation under a concurrent schedules arrangement). The current study evaluated preference among concurrently available communication modalities for 18 individuals with developmental disabilities, including autism spectrum disorder and intellectual disability. Results of the study indicated that each of the individuals demonstrated a preference between communicative response modalities, though preference was not always immediately ascertained. The results are discussed within the context of implications for design and implementation of functional communication training.
