Abstract

Purpose

The reaction time-based Concealed Information Test (RT-CIT) can be used to reveal crime-related memories based on an analysis of response latencies in a computerized task. While laboratory research shows high validity of the RT-CIT in student samples, only very few studies have been conducted with forensic target groups.

Methods

We investigated the applicability and validity of the RT-CIT in prison inmates and examined the influence of a response deadline (RD) on RT-CIT validity. In a within-subjects design, participants memorized a criminal activity and subsequently underwent two identical RT-CITs differing only in the length of the RD (2000 ms vs. 1000 ms). In the first experiment, the 2000 ms condition was always presented first and in the second experiment the order was switched.

Results

Results revealed large effect sizes and classification accuracies with both RDs and strong order effects with larger effects in the respective first RD conditions.

Conclusions

In sum, the RT-CIT has the potential for detecting concealed knowledge in forensic settings and even a relatively demanding RD of 1000 ms seems feasible for such samples. Further research should extend this investigation of the RT-CIT in forensic settings, preferably investigating the effects of faking attempts and increasing the ecological validity of the research design.

基于反应时的隐藏信息测验在监狱样本中的适用性和有效性

目的基于反应时的隐藏信息测验（RT-CIT）可以通过分析计算机化任务中的反应延迟来揭示与犯罪相关的记忆。虽然实验室研究表明RT-CIT在学生样本中具有很高的有效性，但只有很少的研究对法医目标群体进行了研究。方法对监狱在押人员进行问卷调查，考察问卷的适用性和效度，并考察回复时限对问卷效度的影响。在受试者内部设计中，参与者记住了一项犯罪活动，随后进行了两次相同的RT-CITs，只是RD的长度不同（2000毫秒vs 1000毫秒）。在第一个实验中，2000 ms条件总是先出现，在第二个实验中，顺序互换。结果结果表明，两种RD条件下的效应量和分类精度都很大，并且在各自的第一RD条件下具有较强的顺序效应。总之，RT-CIT具有在法医环境中检测隐藏知识的潜力，即使是相对苛刻的1000 ms的RD对于这样的样本似乎也是可行的。进一步的研究应该扩展RT-CIT在法医环境中的调查，最好是调查伪造企图的影响，并提高研究设计的生态效度。
