A class of countermeasures by which an examinee attempts to sway the examiner or influence the conduct of the session. The intent is to influence the decision maker or restrict the ability of the decision maker to conduct a valid examination. By definition, behavioral countermeasures have no influence on the physiologic tracings. The effect is sociopsychological in nature (interpersonal dynamics) rather than psychophysiological. See: Krapohl (1996).
