Want your question answered quickly? Use your hands

People will answer your questions more quickly if you move your hands or head as you talk, researchers have found. The transition between turns taken during a conversation is astonishingly fast, with a mere 200 milliseconds typically elapsing between the contribution of one speaker to the next. Scientists found that gestures that end early may give us an early visual cue that the speaker is about to end, thus helping us to respond faster. Researchers found there was a strong visual component to most questions being asked and answered during the conversations. These took the form of bodily signals such as communicative head or hand movements.
