Abstract

The Response Time Concealed Information Test (RT-CIT) can reveal that a person recognises a relevant item (e.g., a murder weapon) among other control items, based on slower responses to the former compared to the latter ones. To date, the RT-CIT has been predominantly examined only in the context of scenarios that are very unlikely in real life, while sporadic assessment has shown that it suffers from low diagnostic accuracy in more realistic scenarios. In our study, we validated the RT-CIT in the new, realistic, and very topical mock scenario of a cybercrime (Study 1, n = 614; Study 2; n = 553), finding significant though moderate effects. At the same time (and expanded with a concealed identity scenario; Study 3, n = 250), we assessed the validity and generalizability of the filler items presented in the RT-CIT: We found similar diagnostic accuracies when using specific, generic, and even nonverbal items. However, the relatively low diagnostic accuracy in case of the cybercrime scenario reemphasizes the importance of assessments in realistic scenarios as well as the need for further improving the RT-CIT.
