Abstract

Purpose

The Response Time Concealed Information Test (RT-CIT) can reveal when a person recognizes a relevant item among other irrelevant items, based on comparatively slower responses. Therefore, if a person is concealing knowledge about the relevance of this item (e.g., recognizing it as a murder weapon), this deception can be revealed. A recent study introduced additional ‘familiarity-related fillers’, and these items substantially enhanced diagnostic efficiency in detecting autobiographical data. However, the generalizability of the efficiency of fillers to other scenarios remains an open question. We empirically investigated whether new importance-related fillers enhanced diagnostic efficiency in an imaginary crime scenario.

Methods

Two hundred and thirty-nine volunteers participated in an independent samples experiment. Participants were asked to imagine either committing a crime (‘guilty’ group) or to imagine visiting a museum (‘innocent’ group). Then, all participants underwent RT-CIT testing using either a standard single probe or an enhanced single probe (with importance-related fillers) protocol.

Results

The enhanced RT-CIT (with importance-related fillers) showed high diagnostic efficiency (AUC = .810), and significantly outperformed the standard version (AUC = .562). Neither dropout rates nor exclusion criteria influenced this enhancement.

Conclusions

Importance-related fillers improve diagnostic efficiency when detecting episodic information using the RT-CIT and seem to be useful in detecting knowledge in a wide range of scenarios.

重要性相关的填充物提高了犯罪场景中反应时间隐藏信息测试的分类准确性

目的。反应时间隐藏信息测试(RT-CIT)可以根据相对较慢的反应，揭示一个人何时在其他不相关的项目中识别出相关的项目。因此，如果一个人隐瞒了关于这个物品相关性的知识(例如，承认它是一件谋杀武器)，这种欺骗就会被揭露。最近的一项研究引入了额外的“熟悉度相关填充物”，这些填充物大大提高了检测自传体数据的诊断效率。然而，填充物的效率在其他情况下的普遍性仍然是一个悬而未决的问题。我们实证研究了在一个虚构的犯罪场景中，新的与重要性相关的填充物是否提高了诊断效率。
