In this review, the evolution of new P300-based protocols for detection of concealed information is summarized. The P300-based complex trial protocol (CTP) is described as one such countermeasure (CM)-resistant protocol. Recent lapses in diagnostic accuracy (from 90% to 75%) with CTPs applied to mock crime protocols are summarized, as well as recent enhancements to the CTP which have restored accuracy. These enhancements include 1) use of performance feedback during testing, 2) use of other ERP components such as N200 in diagnosis, 3) use of auxiliary tests, including the autobiographical implicit association test, as leading to restored diagnostic accuracy, and 4) a study of the mechanisms underlying CMs. A novel, doubly efficient version of the CTP involving presentation of two probes in one trial is described as a new way to improve accuracy to levels above 90% in mock crime situations. Finally, a thorough analysis of the legal issues surrounding use of the CTP in U.S. is given.
在这篇综述中，总结了新的基于 P300 的隐蔽信息检测协议的发展。基于 P300 的复杂试验协议（CTP）被描述为一种抗对策（CM）的协议。最近，应用于模拟犯罪协议的 CTP 诊断准确性（从 90%降至 75%）的失误被总结，以及最近对 CTP 的增强，恢复了准确性。这些增强包括 1）在测试过程中使用性能反馈，2）在诊断中使用其他 ERP 成分，如 N200，3）使用辅助测试，包括自传体内隐联想测验，导致诊断准确性恢复，以及 4）对 CM 机制的研究。描述了一种新的、双重高效的 CTP 版本，涉及在一次试验中呈现两个探针，作为在模拟犯罪情况下将准确性提高到 90%以上的新方法。最后，对 CTP 在 美国使用的法律问题进行了全面分析。
