Abstract

The purpose of this study was to determine the effects of divided attention on concurrent speech and linguistic tasks by investigating performance on three linguistic computer tasks (phonological, syntactic, and semantic) and speech kinematics. Thirty-seven healthy young adults (19 male, 18 female) ages 19-30 were recorded performing a sentence repetition task using electromagnetic articulography. Each participant completed the sentence repetition once in isolation and once concurrently with each of the three linguistic computer tasks. Participants also completed computer tasks in isolation. Significant dual-task effects were observed on total number of correct responses in the phonological and syntactic linguistic tasks. No significant dual-task effects were observed for the semantic task. No significant dual-task effects were observed in speech motor performance. The results of this study indicate divided attention interference in linguistic task performance across multiple linguistic domains.
