ABSTRACT
Nonverbal behavior is a direct visual representation indicating the development of the fight-or-flight survival response in the subject. If our verbal behaviors give the observer cues to our thoughts, then our body language gives away our emotions, any stress we may be experiencing, and the degree of that stress. The stronger the emotional or stress response we are experiencing, the harder it is for us to censor it from the view of an observer (Darwin, 1872; Darwin and Ekman, 1998). As a result of this connection between emotions and nonverbal behavior, observation of body language changes and clusters is a relatively more accurate source for determining deception with regards to emotion. The stress response is demonstrated through the four stress-response states of anger, depression, denial, and bargaining, or by the absence of fight-or-flight, which is evidence of acceptance.
