Event-related potential (ERP) studies about deception often apply recognition tasks. It remains questionable whether reported ERP patterns and cognitive processes can be generalized to other contexts. As the study by Johnson et al. (2008) fills this gap by investigating deception regarding attitudes, we tried to replicate it. Participants (N = 99) were instructed to lie or tell the truth about their attitudes. We obtained the same results as Johnson et al. (2008): lies were accompanied by enhanced medial frontal negativities (MFN) and suppressed late positive components (LPCs) indicating that lying relied on stronger cognitive control processes and response conflicts than being honest. The amplitudes of pre-response positivities (PRP) were reduced for lies implying that lies about attitudes were accompanied by strategic monitoring. MFN amplitudes increased and LPC amplitudes decreased for lies about positively valued items revealing that lying about positively valued items is cognitively more challenging than lying about negatively valued items. As a new finding, MFN, LPC and PRP components were neither moderated by Machiavellianism nor by changes in the attitude ratings. The results indicate that LPC, MFN and PRP components are reliable indicators of the cognitive processes used during deception and that it is worthwhile to investigate them in further deception contexts.

欺骗期间关于态度的认知过程重新审视：一项复制研究。


关于欺骗的事件相关电位（ERP）研究经常应用识别任务。所报告的 ERP 模式和认知过程是否可以推广到其他环境仍然值得怀疑。正如约翰逊等人的研究。 （2008）通过调查有关态度的欺骗来填补这一空白，我们试图复制它。参与者（ N = 99）被要求对他们的态度撒谎或说出真相。我们得到了与 Johnson 等人相同的结果。 (2008)：谎言伴随着内侧额叶负性成分 (MFN) 的增强和晚期正性成分 (LPC) 的抑制，这表明说谎比诚实更依赖于更强的认知控制过程和反应冲突。谎言的预反应积极性（PRP）幅度降低，这意味着关于态度的谎言伴随着战略监控。对于正面价值项目的谎言，MFN 幅度增加，LPC 幅度下降，这表明，正面价值项目的谎言比负面价值项目的谎言在认知上更具挑战性。作为一项新发现，MFN、LPC 和 PRP 组成部分既不受马基雅维利主义的影响，也不受态度评级变化的影响。结果表明，LPC、MFN 和 PRP 组件是欺骗过程中使用的认知过程的可靠指标，值得在进一步的欺骗环境中研究它们。
