Studies have shown that presenting own-name stimuli on the fringe of awareness in Rapid Serial Visual Presentation (RSVP) generates a P3 component and provides an accurate and countermeasure resistant method for detecting identity deception (Bowman et al., 2013, 2014). The current study investigates how effective this Fringe-P3 method is at detecting recognition of familiar name stimuli with lower salience (i.e., famous names) than own-name stimuli, as well as its accuracy with multi-item stimuli (i.e., first and second name pairs presented sequentially). The results demonstrated a highly significant ERP difference between famous and non-famous names at the group level and a detectable P3 for famous names for 86% of participants at the individual level. This demonstrates that the Fringe-P3 method can be used for detecting name stimuli other than own-names and for multi-item stimuli, thus further supporting the method's potential usefulness in forensic applications such as in detecting recognition of accomplices.
研究表明，在快速序列视觉呈现 (RSVP) 中呈现处于意识边缘的自身姓名刺激会产生 P3 成分，并且为检测身份欺骗提供了一种准确且抗对策的方法（Bowman 等人，2013 年，2014 年）。本研究调查了这种边缘 P3 方法在检测对低显著性的熟悉姓名刺激（即著名姓名）的识别方面的有效性，以及它对多项刺激（即依次呈现的第一和第二名字对）的准确性。结果表明，在组水平上，著名姓名和非著名姓名之间存在非常显著的 ERP 差异，在个体水平上，86%的参与者可检测到著名姓名的 P3。这表明，边缘 P3 方法可用于检测自身姓名以外的姓名刺激和多项刺激，从而进一步支持该方法在法医应用中的潜在有用性，例如检测对同谋的识别。
