The article mentions approximations of two clinical cases, one that was published in Language, Speech, and Hearing Services in Schools (Hyppa Martin, Reichle, Dimian, & Chen, 2013) and another that was presented at the annual American Speech-Language-Hearing Association Convention (Hanowski, Warzonek, Hyppa-Martin, & Mizuko, 2015). This article does not utilize the original data and only references the original studies as examples of single subject experimental designs.

Single subject experimental designs are a clinical tool that enable speech-language pathologists to make low-inference, data-driven intervention decisions and can be particularly useful when treating heterogeneous clinical populations for which there is limited directly applicable extant scientific evidence. Single-subject experimental designs are also useful in supporting the development of clinical expertise for speech-language pathologists and graduate students. This article provides a basic overview of the role of single-subject experimental designs in augmentative and alternative communication clinical education and the potential contributions that the application of these designs can make to the field of augmentative and alternative communication.
