Body language and other nonverbal behavior also can be a highly informative method for understanding communication processes. For example, at another meeting conducted by a manager, the animated discussion at the start of the meeting was interrupted by the second-in-command who said, “This is a problem-solving meeting, not a gripe session.” As the manager continued to talk, the fourteen other members present assumed expressions of concentration. Within twenty-five minutes, all of them had folded their arms and were leaning backward, a sure sign that they were blocking out or shutting off the message. Within ten seconds of the manager’s subsequent statement, “We are interested in getting your ideas,” those present unfolded their arms and began to lean forward, a clear nonverbal sign that they were involved once again.
