Abstract

This study examined the neural signatures associated with conflict-monitoring, recognition and feedback processing in a feedback Concealed Information Test (fCIT), and also examined whether all the ERPs can be used to detect concealed autobiographical information. Participants were randomly assigned to one of two groups (guilty or innocent) and then tested in the fCIT while undergoing electroencephalograms (EEGs). The results showed that the probe (participants' name) elicited a more negative N200, and a more positive recognition P300 than irrelevants among guilty participants. Additionally, feedback following the probe elicited a larger feedback P300 than feedback following irrelevants. Further, we found that three indicators, including the conflict-monitoring N200, recognition P300, and feedback P300, could significantly discriminate between guilty and innocent participants, whereas the FRN could not. Combining them is highly effective in discriminating between guilty and innocent participants (AUC = 0.91). These findings not only shed light on the neural processing of the fCIT but also suggest the potential of using the fCIT to detect concealed autobiographical information.

结合识别、冲突监测和反馈相关的 ERP 来检测隐藏的自传信息。

本研究考察了反馈隐藏信息测试（fCIT）中与冲突监控、识别和反馈处理相关的神经特征，还考察了是否所有的ERPs都可用于检测隐藏的自传信息。受试者被随机分配到两组中的一组（有罪或无罪），然后在接受脑电图（EEG）的同时接受 fCIT 测试。结果显示，与无关信息相比，探究信息（参与者的姓名）在有罪参与者中引起了更消极的 N200 和更积极的识别 P300。此外，探究后的反馈比无关内容后的反馈引起更大的反馈 P300。此外，我们还发现，包括冲突监测 N200、识别 P300 和反馈 P300 在内的三个指标可以显著区分有罪和无罪参与者，而 FRN 则不能。将这三个指标结合在一起，对区分有罪和无罪参与者非常有效（AUC = 0.91）。这些发现不仅揭示了 fCIT 的神经处理过程，还表明了使用 fCIT 检测隐藏的自传信息的潜力。

期刊介绍： Founded in 1964, Psychophysiology is the most established journal in the world specifically dedicated to the dissemination of psychophysiological science. The journal continues to play a key role in advancing human neuroscience in its many forms and methodologies (including central and peripheral measures), covering research on the interrelationships between the physiological and psychological aspects of brain and behavior. Typically, studies published in Psychophysiology include psychological independent variables and noninvasive physiological dependent variables (hemodynamic, optical, and electromagnetic brain imaging and/or peripheral measures such as respiratory sinus arrhythmia, electromyography, pupillography, and many others). The majority of studies published in the journal involve human participants, but work using animal models of such phenomena is occasionally published. Psychophysiology welcomes submissions on new theoretical, empirical, and methodological advances in: cognitive, affective, clinical and social neuroscience, psychopathology and psychiatry, health science and behavioral medicine, and biomedical engineering. The journal publishes theoretical papers, evaluative reviews of literature, empirical papers, and methodological papers, with submissions welcome from scientists in any fields mentioned above.
