Information Test

The reaction time (RT)-based Concealed Information Test (CIT) allows for the detection of concealed knowledge (e.g., one’s true identity) when the questions are presented randomly (multiple-probe protocol), but its performance is much weaker when questions are presented in blocks (e.g., first question about surname, then about birthday; single-probe protocol). The latter test protocol, however, is the preferred and sometimes even the only feasible interviewing method in real-life. In a first, pre-registered, experiment (n = 363), we show that the validity of the single-probe protocol version can be substantially improved by including familiarity-related filler trials (e.g., “KNOWN,” “UNKNOWN”). We replicated these findings in a second, preregistered, experiment (n = 237), where we further found that the use of familiarity-related fillers even improved the classic multiple-probe protocol. We recommend the use of familiarity-related filler trials for the RT-based CIT.

Information Test

In recent years, numerous studies were published on the reaction time (RT)-based Concealed Information Test (CIT). However, an important limitation of the CIT is the reliance on the recognition of the probe item, and therefore the limited applicability when an innocent person is aware of this item. In the present paper, we introduce an RT-based CIT that is based on item-category associations: the Association-based Concealed Information Test (A-CIT). Using the participants’ given names as probe items and self-referring “inducer” items (e.g., “MINE” or “ME”) that establish an association between ownership and responses choices, in Experiment 1 (within-subject design; n = 27), this method differentiated with high accuracy between guilty and innocent conditions. Experiment 2 (n = 25) replicated Experiment 1, except that the participants were informed of the probe item in the innocent condition—nonetheless, the accuracy rate remained high. Implications and future possibilities are discussed.
