Purpose: In our previous studies, we showed that the brain modulates the auditory system, and the modulation starts during speech planning. However, it remained unknown whether the brain uses similar mechanisms to modulate the orofacial somatosensory system. Here, we developed a novel behavioral paradigm to (a) examine whether the somatosensory…

Purpose: The Motor Planning Theory of Prosody and reading prosody research indicate that "out of the blue" oral reading, as practiced in clinical and research settings, invokes surface rather than covert prosody, particularly when readers are recorded, less skilled, and/or speech impaired. Warm-up is not considered in passage reading for…

Purpose: We review and interpret our recent series of studies investigating motor-to-auditory influences during speech movement planning in fluent speakers and speakers who stutter. In those studies, we recorded auditory evoked potentials in response to probe tones presented immediately prior to speaking or at the equivalent time in no-speaking…

Purpose: Previous eye-tracking research has suggested that individuals with aphasia (IWA) do not assign syntactic structure on their first pass through a sentence during silent reading comprehension. The purpose of the present study was to investigate the time course with which lexical variables affect silent reading comprehension in IWA. Three…

Purpose: The aim of this article is to examine the effects of visual image degradation on performance and gaze behavior in audiovisual and visual-only speech perception tasks. Method: We presented vowel-consonant-vowel utterances visually filtered at a range of frequencies in visual-only, audiovisual congruent, and audiovisual incongruent…
