Perspectives on Motor Speech and Cognition Interactions: Advancing the Dialogue
Ida Stockman, Lisa Goffman, Deborah Hayden, Ray Kent, Edythe Strand

A number of scholars and clinicians embrace the view that speech production is influenced by cognition. The proposed session gives voice to this perspective by summarizing conceptual, research and clinical frameworks that support it in the context of developing linguistic cognition. Despite evidence that speech is a linguistic and motor accomplishment, models of speech production and of language learning, phonological representation included, have evolved with few if any assumptions about how either one influences the other. The separation of professional disciplines is especially apparent when clinical interventions are framed exclusively in oral motor or linguistic terms. Narrowly framed interventions are challenged by evidence that motor speech and nonspeech deficits co-occur with linguistic ones across a broad range of communication disorders. Three content themes will illustrate the interactive motor speech/cognition perspective: (1) motor speech control is tempered by cognitive linguistic and nonlinguistic factors; (2) sensorimotor aspects of speech production involve tactual-kinesthetic properties that serve the cognitive mapping or representation of speech sounds in addition to their roles in the online execution of articulatory events; (3) patterns of linguistic development may be explained by motor/physical factors and vice versa. These themes have theoretical and clinical consequences for motor speech disorders.
