This study examines the processes surrounding investigative interviewing and interrogation, by testing approaches founded in research on strategies of truth telling and deceiving. Participants in this experiment will be asked to watch videotapes of former criminal defendants in interrogations or pre-interrogation interviews conducted by actual police detectives denying involvement in crimes which they either have or have not committed or confessing to crimes which they have or have not committed. The participants will then be asked to make determinations of the suspects' credibility and veracity during the respective phases of the interrogation process.This study differed from previous research in that it investigates the possibility that psychopathic personality moderates a suspect's ability to evade detection while being mendacious. Videotapes will also be coded to determine whether psychopaths differ from nonpsychopaths in their verbal and nonverbal cues while being deceptive. In line with the extant literature, it is hypothesized that a) psychopathic individuals will display verbal and nonverbal cues while lying which differ from nonpsychopathic individuals, b) psychopathy will have a moderating effect on a participant's veracity judgments such that psychopathic individuals will more often be judged as truthful when denying involvement in the crimes they committed, and c) psychopathy will moderate participants' veracity judgments such that the false confessions provided by psychopathic individuals will be seen as more believable than false confessions provided by nonpsychopathic individuals. It is believed that the results of this study will enhance the theoretical understanding of deceptive presentations as well as provide important information to investigative practitioners.

本研究通过检验在关于说真话和欺骗策略的研究中建立的方法来检验围绕调查性访谈和讯问的过程。这项实验的参与者将被要求观看前刑事被告的录像带，这些录像带是由实际的警察侦探在审讯或审问前进行的，他们否认参与了他们已经或没有犯下的罪行，或承认了他们已经犯下或没有犯下的罪行。然后，参与者将被要求在审问过程的各个阶段对嫌疑人的可信度和真实性做出判断。这项研究与之前的研究不同，因为它调查了心理变态人格抑制嫌疑人在撒谎的同时逃避侦查的可能性。录像带也将被编码，以确定精神病患者在具有欺骗性的同时，在语言和非语言线索方面是否与非精神病患者不同。与现有文献一致的是，假设a)精神病患者在撒谎时会表现出与非精神病患者不同的语言和非语言线索，b)精神病患者将对参与者的真实性判断产生调节作用，使得精神病患者在否认其所犯罪行时更多地被判断为真实，以及c)精神病患者将缓和参与者的真实性判断，使得精神病患者提供的虚假供词将被视为比非精神变态个体提供的虚假供词更可信。相信本研究结果将加深对欺骗性陈述的理论理解，并为调查实践者提供重要的信息。
