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

最近的欺骗检测方法（例如，测谎仪测试）依赖于对隐藏信息敏感的脑电波，例如犯罪现场的凶器，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使用P3信号的方法，这些方法对态度等其他信息敏感，而不仅仅是关于物体的信息。然而，重要的问题仍然存在，例如如何引出其他脑电波，这可以提高测试的准确性，该项目的主要智力价值是它超越了先前的隐藏态度研究。 他们通过概述实际的实现和技术来更好地理解欺骗的基本神经过程，从而推进了这一领域。通过使用一种已知的场景来引发与记忆相关的脑电波和对欺骗的竞争反应的脑电波，该研究建立在先前使用脑信号检测知识的研究基础上，将其扩展到检测意图。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，这个测试可能是一个有用的安全检查工具，以检测某人何时有极端的态度。 因此，这个博士研究项目将有助于检测关于态度和意图的欺骗，而不是对象。此外，该研究将在西班牙裔服务机构进行，从而有可能扩大代表性不足的群体成员之间的科学研究机会。

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.
