Current research in apraxia of speech (AOS) strongly supports its conceptualization as a disorder of motor control (e.g., Ballard, Grainer, & Robin, 2000; Ballard & Robin, 2007, for review). Recently, speech-language pathologists have become increasingly interested in examining the contributions that theories of motor control and learning, derived largely from the study of nonspeech motor skills, can make to the clinical management of motor speech disorders such as AOS. The purpose of this article is to introduce principles that have emerged from investigations of general motor learning and summarize the emerging evidence concerning their application to AOS treatment that has accumulated since the last time an article was published in Perspectives on this topic (Ballard, 2001).
