Recent studies have demonstrated that lying can affect memory and that such memory effects are based on the cognitive load required in performing the lie. The present study aimed to verify whether the impact of two deceptive strategies (i.e., false denials and fabrication) depends on individuals' cognitive resources in terms of Executive Functions (i.e., EF: Shifting, Inhibition, and Updating). A sample of 147 participants watched a video of a robbery and then were instructed to either fabricate (i.e., fabrication condition), deny (i.e. false denial condition), or tell the truth (i.e., truth-telling condition) to some questions about the crime. Two days later, all participants had to provide an honest account on a final memory test where they indicated their memory for having discussed details (i.e., fabricated, denied, or told the truth) and their memory for the video. Finally, their EF resources were also assessed. Our findings demonstrated that individual differences in EFs played a role in how the event was recalled and on the effects of lying on memory. That is, memory for the event after having lied depended especially on individuals' Shifting resources. We also found that the two deceptive strategies differentially affected individuals' memory for the interview and for the event: Denying affected memory for the interview while fabricating affected memory for the event. Our findings can inform legal professionals on the possibility to assess individuals' EF as an indicator of witnesses' credibility.

最近的研究表明，撒谎会影响记忆力，而这种记忆效应是基于进行撒谎所需的认知负荷。本研究旨在验证两种欺骗策略（即错误的否认和捏造）的影响是否取决于个人在执行功能（即EF：转移，抑制和更新）方面的认知资源。147名参与者的样本观看了抢劫的视频，然后被指示进行伪造（即制造条件），拒绝（即虚假否认条件）或向真相（即讲真言的条件）提出一些有关抢劫的问题。犯罪。两天后，所有参与者都必须在最终的记忆力测试中提供诚实的陈述，表明他们对讨论细节的记忆（例如，捏造，拒绝，或说实话）及其对视频的记忆。最后，他们的EF资源也得到了评估。我们的研究结果表明，EF的个体差异在事件的召回方式和说谎对记忆的影响中发挥了作用。也就是说，撒谎后对事件的记忆尤其取决于个人的转移资源。我们还发现，两种欺骗性策略会不同程度地影响个人对访谈和事件的记忆：拒绝对访谈的影响记忆，而为事件制造受影响的记忆。我们的发现可以使法律专业人士了解评估个人EF的可能性，以此作为证人可信度的指标。我们的研究结果表明，EF的个体差异在事件的召回方式和说谎对记忆的影响中发挥了作用。也就是说，撒谎后对事件的记忆尤其取决于个人的转移资源。我们还发现，两种欺骗性策略会不同程度地影响个人对访谈和事件的记忆：拒绝对访谈的影响记忆，而为事件制造受影响的记忆。我们的发现可以使法律专业人士了解评估个人EF的可能性，以此作为证人可信度的指标。我们的研究结果表明，EF的个体差异在事件的召回方式和说谎对记忆的影响中发挥了作用。也就是说，撒谎后对事件的记忆尤其取决于个人的转移资源。我们还发现，两种欺骗性策略会不同程度地影响个人对访谈和事件的记忆：拒绝对访谈的影响记忆，而为事件制造受影响的记忆。我们的发现可以使法律专业人士了解评估个人EF的可能性，以此作为证人可信度的指标。我们还发现，两种欺骗性策略会不同程度地影响个人对访谈和事件的记忆：拒绝对访谈的影响记忆，而为事件制造受影响的记忆。我们的发现可以使法律专业人士了解评估个人EF的可能性，以此作为证人可信度的指标。我们还发现，两种欺骗性策略会不同程度地影响个人对访谈和事件的记忆：拒绝对访谈的影响记忆，而为事件制造受影响的记忆。我们的发现可以使法律专业人士了解评估个人EF的可能性，以作为证人可信度的指标。
