Chapter 6 reviews a range of nonverbal cues used in communication such as eye gaze in its interactional role (e.g., directing turn-taking), head movements, and manual gestures, in addition to the technologies available to examine the co-occurrence of head nods, eyeblinks, brow raise, lip movements, manual gestures, and features of speech (e.g., pitch-accented vowels). As with other components of a speech event, variability exists across speakers and cultures in their gestures, and familiarity plays a role in the contribution of a speaker’s gestures to comprehension as it does for accent and topic.
