基于反应时间的隐藏信息测试（RT-CIT）可以根据一个人对探测项目相对较慢的反应，揭示一个人在其他不相关项目中识别出一个相关（探测）项目的能力。例如，如果一个人隐藏自己的真实身份，可以将可疑的身份细节作为探针，而将其他随机细节作为无关事项。然而，在我们的研究中，我们表明，即使参与者在执行RT-CIT之前仅仅被告知这些探针（即相关的身份细节），他们对这些细节的反应也会变慢。因此，很难区分这些无辜但事先知情的人与真正有罪的人。与此同时，我们引入了一个CIT版本，其中包含与熟悉度相关的诱导刺激，但没有目标，仅在有罪参与者中引起探针减去无关RT差异，而在知情的无辜参与者中则没有。讨论了cit的理论和应用意义。
The Response Time-Based Concealed Information Test (RT-CIT) can reveal when a person recognizes a relevant (probe) item among other, irrelevant items, based on comparatively slow responses to the probe item. For example, if a person is concealing his or her true identity, one can use the suspected identity details as probes, and other, random details as irrelevants. However, in our study, we show that even when participants are merely informed about such probes (i.e., the relevant identity details) before performing the RT-CIT, their responses will also be slower to these details. Hence, it is more difficult to distinguish such innocent but pre-informed persons from actually guilty persons. At the same time, we introduce a CIT version with familiarity-related inducer stimuli, but with no targets, that elicits probe-minus-irrelevant RT differences only among guilty participants but not among informed innocent participants. Implications for the theory and the application of CITs are discussed.
