The response time concealed information test (RT-CIT) can reveal that a person recognizes a relevant item (probe) among other, irrelevant items, based on slower responding to the probe compared to the irrelevant items. Thereby, if this person is concealing knowledge about the relevance of this item (e.g., recognizing it as a murder weapon), this deception can be unveiled. In the present paper, we examined the impact of a speed versus accuracy instruction: Examinees (N = 235) were either presented with instructions emphasizing a focus on speed, with instructions emphasizing a focus on accuracy, or with no particular speed or accuracy instructions at all. We found that although participants responded to the probe and the irrelevants marginally faster when they had received instructions emphasizing speed, there was no significant difference between RTs of the different experimental groups and crucially no significant difference between the probe-irrelevant RT differences either. This means that such instructions are unlikely to benefit the RT-CIT, but it also suggests that related deliberate manipulation (focusing on speed on or accuracy) is unlikely to decrease the efficiency of the RT-CIT-contributing further evidence to the RT-CIT's resistance to faking.
反应时间隐藏信息测试（RT-CIT）可以揭示一个人是否能够根据与其他无关项目相比，对相关项目（探针）的反应较慢来识别相关项目。因此，如果这个人对该项目的相关性有所隐瞒（例如，将其识别为杀人凶器），那么这种欺骗行为就可以被揭露出来。在本文中，我们研究了速度与准确性指令的影响：受测者（N=235）分别接受了强调速度、强调准确性或没有特定速度或准确性指令的指导。我们发现，尽管参与者在收到强调速度的指令时，对探针和无关项目的反应稍微快一些，但不同实验组的反应时之间没有显著差异，关键是探针与无关项目之间的反应时差异也没有显著差异。这意味着这种指令不太可能有益于 RT-CIT，但也表明相关的刻意操纵（关注速度或准确性）不太可能降低 RT-CIT 的效率，进一步证明了 RT-CIT 不易被伪造。
