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 event-related 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.

心理对策对一种新颖的基于大脑的反馈隐藏信息测试的影响

反馈隐藏信息测试 (fCIT) 是 CIT 的一种新颖形式，为参与者提供有关其记忆隐藏性能的反馈。fCIT 利用事件相关电位（识别-P300 和反馈相关事件相关电位），并已被证明在检测信息隐藏方面提供高效率。然而，目前尚不清楚 fCIT 在存在心理对策的情况下表现如何。为了解决这个问题，参与者接受了在 fCIT 期间使用对策的培训。结果表明，当参与者使用对策时，识别-P300 效率降低。然而，与反馈相关的负性和反馈-P300 的效率没有变化，反馈-P300 在对策期间仍显示出较高的检测效率（AUC = 0.86）。
