This laboratory study dealt with real-life intense emotional events. Subjects generated embarrassing stories from their experience, then submitted to polygraph testing and, by lying, denied their stories and, by telling the truth, denied a randomly assigned story. Money was given as an incentive to be judged innocent on each story. An interrogator, blind to the stories, used Control Question Tests and found subjects more deceptive when lying than when truthful. Stories interacted with order such that lying on the second story was more easily detected than lying on the first. Embarrassing stories provide an alternative to the use of mock crimes to study lie detection in the laboratory.
这项实验室研究涉及现实生活中的强烈情感事件。受试者根据自身经历编造尴尬故事，然后接受测谎测试，通过说谎否认自己编造的故事，并通过说实话否认一个随机分配的故事。研究给予金钱作为在每个故事上被判定无罪的奖励。一名对故事不知情的审讯者使用对照问题测试，发现受试者说谎时比说实话时更具欺骗性。故事与顺序存在交互作用，以至于在第二个故事上说谎比在第一个故事上说谎更容易被察觉。尴尬故事为在实验室中使用模拟犯罪来研究测谎提供了一种替代方法。
