An exploration of motor learning concepts relevant to use of speech-generating devices.

For individuals who rely on speech-generating devices (SGDs) to complement and substitute for spoken language, speed, and accuracy of access to the device are paramount for effective communication. There is some evidence that application of motor memory principles may improve effectiveness of SGD-based communication. This article reviews motor learning models and principles, including learning stages, types of practice, and environmental factors that affect learning, and highlights the potential applications of these principles in dynamic display SGD design, intervention, and research.
