The project examines the role of working memory capacity (WMC) in lying. WMC is the ability to use focused attention and cognitive effort to accomplish goals. Anything that requires attention and concentration will use WMC. Research indicates that lying may require more WMC than telling the truth because lying requires suppressing truthful information, generating a lie to tell, and telling that lie in a believable way, among other cognitive tasks. In comparison, telling the truth primarily requires recall of information. Previous research shows that liars display some behaviors which indicate cognitive load. When liars and truth tellers are placed under extra cognitive load, such behaviors become more pronounced in liars compared to truth tellers. These behaviors can be used to more accurately distinguish liars from truth tellers. The current research will examine how this finding is affected by WMC, as research has shown that WMC is related to an individual?s ability to cope with cognitive load. In Studies 1 and 2 participants will lie or tell the truth either under cognitive load or no cognitive load. WMC will be measured to examine its impact on verbal, vocal, and visual behavior. In Study 3, observers will judge the truthfulness of participants from Studies 1 and 2. This project will help advance the understanding of how working memory affects deception, specifically whether individuals with greater WMC are better at coping with cognitive load during lying. This project will also expand research on individual differences in the deception field by studying how variation in a particular cognitive capacity affects deceptive behavior. Learning more about lying and truth telling can aid law enforcement and other groups who face the task of judging credibility in their professional life. This research can be used to help develop methods of lie detection that exploit the cognitive processes of liars. In addition, this project will contribute to the training of a graduate student.

该项目研究了工作记忆容量（WMC）在说谎中的作用。WMC是使用集中注意力和认知努力来实现目标的能力。任何需要注意力和集中的事情都将使用WMC。研究表明，撒谎可能需要比说实话更多的WMC，因为撒谎需要压制真实的信息，产生一个谎言，并以可信的方式说出谎言，以及其他认知任务。相比之下，讲真话主要需要回忆信息。以往的研究表明，说谎者会表现出一些反映认知负荷的行为。当说谎者和说真话者被置于额外的认知负荷下时，与说真话者相比，说谎者的这种行为变得更加明显。这些行为可以用来更准确地区分说谎者和说真话者。目前的研究将探讨这一发现是如何受到WMC的影响，因为研究表明，WMC是与个人？科普认知负荷的能力。在研究1和2中，被试会在认知负荷或无认知负荷的情况下撒谎或说真话。WMC将被测量，以检查其对语言，声音和视觉行为的影响。在研究3中，观察员将判断研究1和2的参与者的真实性。这个项目将有助于推进工作记忆如何影响欺骗的理解，特别是具有更大WMC的个体是否更好地应对说谎过程中的认知负荷。该项目还将通过研究特定认知能力的变化如何影响欺骗行为，扩大对欺骗领域个体差异的研究。了解更多关于说谎和说真话的知识可以帮助执法人员和其他在职业生活中面临判断可信度任务的群体。这项研究可以用来帮助开发利用说谎者认知过程的测谎方法。 此外，该项目将有助于培养一名研究生。
