Distinguish between what is communicative nonverbal behavior and what is not

Please provide the best answer for the best statement.

Answer: The nonverbal components of communication include all the messages that people transmit through means other than words. Some researchers believe nonverbal communication stands for something, whereas nonverbal behavior may not. For example, scratching one’s arm usually isn’t intended by the scratcher, nor understood by the observer, to convey a particular message. Although it may provide information (that one’s arm itches), it doesn’t necessarily signal an intentional message. Rather, it would be considered an involuntary bodily “output.” However, these scholars would argue that in baseball when a manager scratches his arm to signal that a runner on base should steal home, scratching the arm is symbolic and, therefore, an instance of nonverbal communication. Nonetheless, these scholars acknowledge that some nonverbal communication does lack the element of intentionality.
