chicken game

a type of laboratory game used in experimental investigations of bargaining and competition, in which each party in the interaction can win only by selecting the competitive rather than the cooperative alternative. For example, if two cars traveling in opposite directions are stopped at a narrow intersection without traffic lights and both drivers are in a hurry, each motorist may want to start first across the intersection, pursuing his or her own interest (i.e., choosing the competitive alternative) and hoping that the other will give way (i.e., will adopt the more cooperative strategy). The danger is that if both parties choose the competitive strategy, both lose. This game differs from the prisoner’s dilemma, in which both parties have incentives both to cooperate and compete with their partner. See also game theory.

guilty knowledge test

guilty knowledge test

a form of lie detection in which knowledge about the details of a crime is tested. A polygraph examiner presents examinees with multiple-choice questions concerning the crime, to which only the guilty party should know the correct answers; it is assumed that innocent examinees will see all options as equally plausible. The polygraph examiner measures the examinees’ physiological arousal as each option is presented and identifies which option produces the highest physiological response. Over a series of questions, if an individual consistently shows the greatest response to the correct option, the examiner may identify that person as untruthful in his or her denial of knowledge of the details of the crime. See also control question test; relevant–irrelevant test.
