The reaction time-based Concealed Information Test (RT-CIT) can be used to detect information a suspect wishes to conceal. While it is often argued that it is easily faked, empirical research on its vulnerability to faking is scarce. In three experiments, we tested whether receiving faking instructions enables guilty participants to fake an innocent test outcome in an RT-CIT. In Experiment 1, when not using a response deadline, we found the RT-CIT to be vulnerable to faking (d = 1.06). Experiment 2 showed that when using a response deadline, faking was ineffective (d = −0.25). Critically, Experiment 3 replicated these findings within one between-subject design, showing again a faking effect when no response deadline was used (d = 1.08) that vanished with the use of a response deadline (d = −0.56). By providing suggestions for the development of a faking detection algorithm, we hope to stimulate further research in this area.

基于反应时间的隐藏信息测试 (RT-CIT) 可用于检测嫌疑人希望隐藏的信息。虽然人们经常认为它很容易被伪造，但关于其对伪造的脆弱性的实证研究很少。在三个实验中，我们测试了接收伪造指令是否能让有罪的参与者在 RT-CIT 中伪造一个无辜的测试结果。在实验 1 中，当不使用响应截止日期时，我们发现 RT-CIT 容易被伪造（d = 1.06）。实验 2 表明，当使用响应截止日期时，伪造是无效的（d = -0.25）。至关重要的是，实验 3 在一个被试间设计中复制了这些发现，再次显示了当没有使用响应截止日期时的假装效果（d= 1.08）随着使用响应截止日期（d = -0.56）而消失。通过为伪造检测算法的开发提供建议，我们希望激发该领域的进一步研究。
