Chapter 2 outlines the role of visible speech cues in perception across the lifespan. Research on the integration of auditory and visual cues in speech perception flourished after the initial publication of the perceptual illusion known as the McGurk-McDonald effect in 1976, and ultimately, included research on the effect as experienced by native speakers of several languages in addition to English, and second-language learners. This illusory effect has contributed to our understanding of the neurophysiological processing of speech.
