Question: Nonverbal communication (e.g., the use of hand gestures) is a common form of human expression . Some researchers believe it may even help people make quicker decisions. To test this belief, a team of researchers conducted a study in which they recorded the time it took 12 college students to count scattered dots on a computer screen. Half (n = 6) the students pointed to the dots as they counted (Group Gesture); the other half (n = 6) were told not to point as they counted (Group No Gesture). The table lists the time it took students in each group to correctly count the dots (in seconds).
