Doctoral Dissertation Research: A Priming Paradigm for Eliciting Neural Correlates of Concealed Attitudes

最近的欺骗检测方法（如测谎仪测试）依赖于对隐藏信息敏感的脑电波，如犯罪现场的谋杀武器，称为P3。然而，这种隐藏信息的方法并不适用于隐藏信息很重要的许多情况。例如，它没有筛选潜力。因此，研究人员已经开始研究其他可以利用P3信号的方法，这些方法对态度等附加信息敏感，而不仅仅是关于物体的信息。然而，重要的问题仍然存在，比如如何激发其他脑电波，从而提高测试的准确性。这个项目的主要智力价值在于它超越了先前的隐蔽态度研究。他们通过概述实际实现和技术来更好地理解欺骗的基本神经过程，从而推动了这一领域的发展。通过使用已知的场景来引出与记忆相关的脑电波和对欺骗的竞争性反应的脑电波，该研究建立在先前使用大脑信号来检测知识的研究的基础上，将它们扩展到检测意图。这些发现对执法实践具有重要意义，因为与其他隐藏信息的测试不同，这种测试可能是一种有用的安全筛选工具，可以检测某人是否有极端的态度。因此，这个博士研究项目将有助于发现关于态度和意图的欺骗，而不是对象。此外，这项研究将在西班牙裔服务机构进行，从而可能扩大在代表性不足的群体成员中进行科学研究的机会。

Recent deception detection approaches (e.g., lie detector tests) rely upon a brainwave sensitive to concealed information, such as a murder weapon at a crime scene, called the P3. Yet this concealed information approach does not apply in many circumstances where concealed information is important. For example, it has no screening potential. Therefore, researchers have begun to investigate other approaches that can use the P3 signal and that are sensitive to additional informationsuch as attitudes, rather than just information about objects. However, important questions remain, such as how to elicit other brainwaves, which could enhance the accuracy of the test.The primary intellectual merit of this project is its extension beyond prior concealed attitude studies. They advance the field by outlining both practical implementations and techniques for better understanding the basic neural processes of deception. Through use of a scenario known to elicit the memory-related brain wave and a brain wave for competing responses to deception, the research builds upon prior studies using brain signals to detect knowledge, extending them here to detect intentions.These findings have important implications for law enforcement practice because, unlike other tests of concealed information, this test may be a useful security screening tool to detect when someone has an extreme attitude. Therefore this doctoral research project will contribute to detecting deception about attitudes and intentions, rather than objects. In addition, the research will be conducted at a Hispanic Serving Institution, thus potentially expanding opportunities for science research among members of underrepresented groups.
