Abstract

Converging evidence suggests that stuttering is associated with deficits in the planning and execution of speech. Evidence also suggests that the onset, development, and loci of stuttering are related to demands language places on speech motor planning and execution. We combined linguistic and vocal motor assessments to address two questions: 1) Can we identify a subgroup of adult stutterers who demonstrate linguistic deficits? and 2) Do linguistically normal and impaired stutterers show different patterns of laryngeal reaction time (LRT) as a function of response complexity? Linguistic performance was evaluated using tasks that assess relatively high-level production and comprehension processes. Responses used to record LRT differed in linguistic and motoric complexity. Only linguistically impaired stutterers showed significant increases in LRT for complex responses. Findings suggest that linguistic and motor processes affect the efficiency and fluency of speech motor control and that both processes be made explicit in models of stuttering.
