Purpose: Lipreading and its cognitive correlates were studied in school-age children with typical language development and delayed language development due to specific language impairment (SLI). Method: Forty-two children with typical language development and 20 children with SLI were tested by using a word-level lipreading test and an extensive…

The function of consciousness was explored in two contexts of audio-visual speech, cross-modal visual attention guidance and McGurk cross-modal integration. Experiments 1, 2, and 3 utilized a novel cueing paradigm in which two different flash suppressed lip-streams cooccured with speech sounds matching one of these streams. A visual target was…

One of the ongoing challenges teachers of students who are deaf or hard of hearing face is managing the visual split attention implicit in multimedia learning. When a teacher presents various types of visual information at the same time, visual learners have no choice but to divide their attention among those materials and the teacher and…

Upon hearing an ambiguous speech sound dubbed onto lipread speech, listeners adjust their phonetic categories in accordance with the lipread information (recalibration) that tells what the phoneme should be. Here we used sine wave speech (SWS) to show that this tuning effect occurs if the SWS sounds are perceived as speech, but not if the sounds…

Purpose: To examine several cognitive and perceptual abilities--including working memory (WM), information processing speed (PS), perceptual closure, and perceptual disembedding skill--as factors contributing to individual differences in lipreading performance and to examine how patterns in predictor variables change across age groups. Method:…

Background: Speech perception is often considered specific to the auditory modality, despite convincing evidence that speech processing is bimodal. The theoretical and clinical roles of speech-reading for speech perception, however, have received little attention in speech-language therapy. Aims: The role of speech-read information for speech…
