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.
反馈隐藏信息测试（fCIT）是CIT 的一种新形式，它为参与者提供关于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），已被证明在检测信息隐藏方面具有高效率。然而，在存在心理对策的情况下，fCIT 的性能如何还不清楚。为了解决这个问题，参与者在 fCIT 中接受了使用对策的训练。结果表明，当参与者使用对策时，识别-P300 的效率降低。然而，反馈相关负性和反馈-P300 的效率保持不变，并且在对策期间，反馈-P300 仍然显示出较高的检测效率（AUC=0.86）。这些发现表明 fCIT 有可能破坏对策。
