“…An advantage of the fCIT is that it can also incorporate information from the ERPs associated with the participant receiving feedback on their response to a stimulus to detect concealment of information. In agreement with previous research, both the FRN and the feedback‐P300 can be used to significantly distinguish participants concealing information (the guilty group in the present study) from those who were not (Sai et al, 2016, 2020; Sai, Lin, Hu, & Fu, 2014). Importantly, the use of a mental countermeasure strategy did not have a significant effect on the detection efficiency of either measure.…”

The feedback concealed information test (fCIT) is a novel form of the CIT, providing participants with feedback regarding their memory concealment performance. The fCIT utilizes event-related potentials (recognition-P300 and feedback-related eventrelated potentials) and has been shown to provide high efficiency in detecting information concealment. However, it is unclear how well the fCIT performs in the presence of mental countermeasures. To address this question, participants were trained to use countermeasures during fCIT. Results showed that the recognition-P300 efficiency decreased when participants used countermeasures. However, the efficiencies of feedback-related negativity and feedback-P300 were unchanged, with feedback-P300 still showing a high detection efficiency (AUC = 0.86) during countermeasures. These findings demonstrate the potential of fCIT for subverting countermeasures.

“…In the P300‐based CTP, BSIT is the number of bootstrapped iterations out of 1000 in which the bootstrapped probe P300 amplitude exceeded the bootstrapped irrelevant P300 amplitude. If a participant's BSIT ≥900, it can be inferred that he or she is “guilty” (Davydova et al, 2020; Sai et al, 2020).…”

“…In addition, the cutoff points are also affected by the base-rate of guilt which may differ from case to case, and the arbitrary cutoffs cannot offer any help to future judicial practices (Lieblich et al, 1978). Therefore, this study did not report the individual diagnostic results as the previous studies did (Deng et al, 2021;Lu et al, 2017;Sai et al, 2020).…”

“…BSIT is the number of bootstrapped iterations out of 1000 in which the bootstrapped probe P300 amplitude exceeded the bootstrapped irrelevant P300 amplitude. Generally speaking, if the number of iterations in which the bootstrapped probe P300 amplitude exceeded the bootstrapped irrelevant P300 amplitude is more than 900 times (i.e., BSIT ≥900), it can be inferred that the participant is a “guilty person” (Davydova et al, 2020; Sai et al, 2020). However, due to page limit restrictions, the statistical results of BSIT are not reported in this study.…”

A novel and effective item‐source complex trial protocol: Discrimination of guilty from both knowledgeable and unknowledgeable innocent subjects

et al. 2022

View full text Add to dashboard Cite

Innocent subjects who are knowledgeable of crime‐related information will often be misclassified as “guilty” in P300‐based complex trial protocol (CTP). Therefore, it is necessary to develop a more rigorous CTP that can effectively discriminate the guilty from both the knowledgeable and the unknowledgeable innocents. Sometimes the guilty and the knowledgeable innocents possess the same item memories but different source memories. The present study designed a novel item‐source complex trial protocol based on the differences of source memory among the three kinds of individuals. Either the crime‐related probe (e.g., the stolen ring) or one of the crime‐unrelated stimuli (e.g., watch, earring, bracelet, or bangle) (item memory) was presented in the first part of each trail, and either a stealing‐source word (e.g., stole) or other‐source word (e.g., fetched) (source memory) was presented in the second part of each trail. The results showed that: (1) the P300 evoked by item memory could effectively discriminated the guilty from the unknowledgeable innocent (AUC = 0.76) but failed to effectively discriminate the guilty from the knowledgeable innocent (AUC = 0.60); (2) the late positive component evoked by source memory could effectively discriminated the guilty from both the knowledgeable innocent (AUC = 0.94) and the unknowledgeable innocent (AUC = 0.84) in one test.
