Evidence regarding the validity of reaction time (RT) measures in deception research is mixed. One possible reason for this inconsistency is that structurally different RT paradigms have been used. The aim of this study was to experimentally investigate whether structural differences between RT tasks are related to how effective those tasks are for capturing deception. We achieved this aim by comparing the effectiveness of relevant and irrelevant stimulus-response compatibility (SRC) tasks. We also investigated whether an intended but not yet completed mock crime could be assessed with both tasks. Results showed (1) a larger compatibility effect in the relevant SRC task compared to the irrelevant SRC task, (2) for both the completed and the intended crime. These results were replicated in a second experiment in which a semantic feature (instead of color) was used as critical response feature in the irrelevant SRC task. The findings support the idea that a structural analysis of deception tasks helps to identify RT measures that produce robust group effects, and that strong compatibility effects for both enacted crimes as well as merely intended crimes can be found with RT measures that are based on the manipulation of relevant SRC.
关于反应时间（RT）测量在欺骗研究中的有效性的证据参差不齐。造成这种不一致的一个可能原因是使用了结构不同的RT范式。本研究的目的是通过实验调查RT任务之间的结构差异是否与这些任务捕捉欺骗行为的有效性相关。我们通过比较相关和不相关刺激-反应兼容性（SRC）任务的有效性来实现这一目标。我们还研究了是否可以用这两种任务来评估一个已计划但尚未实施的模拟犯罪。结果表明：（1）与不相关SRC任务相比，相关SRC任务中的兼容性效应更大；（2）对于已实施和计划中的犯罪都是如此。这些结果在第二个实验中得到了重复，在该实验中，一个语义特征（而非颜色）被用作不相关SRC任务中的关键反应特征。这些发现支持了这样一种观点，即对欺骗任务进行结构分析有助于识别能产生稳健组效应的RT测量方法，并且基于相关SRC操作的RT测量方法可以发现已实施犯罪和仅是计划中的犯罪都有很强的兼容性效应。
