关于测谎及其结论的争议与评析 总被引:5,自引:0,他引:5
在关于测谎技术在刑事诉讼中的运用的讨论中 ,对测谎的科学性、准确性以及测谎结论能否作为诉讼证据使用方面存在着不同的看法 ,争论已久。从心理变化引起生理变化的角度看 ,测谎是有其科学根据的 ;现代测谎技术运用高科技手段和多学科原理 ,测试的准确性是有保证的 ;测谎结论由于不具备证据的关联性 ,所以不能作为诉讼证据使用 ,不能作为定案的根据 相似文献

认知脑电测谎一般采用案件图片刺激或者是具有特定意义的字词句来研究。对汉字和图片的ERP相关研究发现了二者都存在新旧效应,但也发现了二者诱发的特异性ERPs成分在潜伏期、波幅、频率等上不同,存在"图片优势效应"。这可能是由于大脑对两种性质不同的刺激材料的认知加工过程差异造成的。本文通过对二种刺激材料的差异研究探讨了在民事和刑事案件中面对不同情况下选择何种刺激材料才能更好地引发目标刺激的反应,有效地提取、识别出特异性目标脑电特征,从而提高检测被测人大脑中是否具有案件相关信息的准确率。 相似文献

Since its introduction into the field of deception detection, the verbal channel has become a rapidly growing area of research. The basic assumption is that liars differ from truth tellers in their verbal behaviour, making it possible to classify them by inspecting their verbal accounts. However, as noted in conferences and in private communication between researchers, the field of verbal lie detection faces several challenges that merit focused attention. The first author therefore proposed a workshop with the mission of promoting solutions for urgent issues in the field. Nine researchers and three practitioners with experience in credibility assessments gathered for 3 days of discussion at Bar-Ilan University (Israel) in the first international verbal lie detection workshop. The primary session of the workshop took place the morning of the first day. In this session, each of the participants had up to 10 min to deliver a brief message, using just one slide. Researchers were asked to answer the question: ‘In your view, what is the most urgent, unsolved question/issue in verbal lie detection?’ Similarly, practitioners were asked: ‘As a practitioner, what question/issue do you wish verbal lie detection research would address?’ The issues raised served as the basis for the discussions that were held throughout the workshop. The current paper first presents the urgent, unsolved issues raised by the workshop group members in the main session, followed by a message to researchers in the field, designed to deliver the insights, decisions, and conclusions resulting from the discussions. 相似文献

In this experiment, both thermal imaging and the Concealed Information Test (CIT) methodologies were adopted, for the first time, to explore the efficacy of the thermal imaging of the thoracolumbar (T1–L3) region of the spinal column within the context of deception detection. Thirty-one participants followed a CIT-based structured interview process in a low-stakes laboratory setting whereby temperature fluctuations induced by the preganglionic neurons in the spinal column were measured with a thermal imaging camera during verbal responses to interview questions. The degree of temperature changes was then analyzed in order to determine truthfulness and deceit. Thermal imaging of the thoracolumbar region of the spinal column during sympathetic activation was effective in determining truthful responses with an accuracy rate of 91.9% and deceitful responses with an accuracy rate of 71.0%. Current findings support the potential use of temperature fluctuations of preganglionic neuron sites in the thoracolumbar section for lie-detection purposes. 相似文献

Levine et al. (2018) criticized our meta‐analysis, but their conclusion was the same as ours: The cognitive approach to lie detection results in a modest improvement. We address and dismiss Levine et al.'s (2018) three criticisms. Regarding the ‘confound’, in our meta‐analysis we averaged the results of two cells on statistical grounds, which does not constitute a confound in statistical terms. Regarding ‘aberrant controls’, that depends entirely on the benchmarks selected and type of statistical test and meta‐analysis used. Regarding ‘unreliable data’, the claim that there is a positive relationship between ‘unreliable’ data and total accuracy in the cognitive lie detection conditions is not even supported by their own data (p = .16). We conclude with a request to Levine et al. to focus on our shared aim: to develop interview protocols that enable lie detection. 相似文献

One of the major problems of courts and insurance companies is the lack of a proper technique to determine the rate of responsibility of the parties involved in the accident. The aim of this study was to determine the Accident/Occupational Diseases Responsibility Rates (AOD RR) for complex events. Accordingly, a case study of a complex accident of carbon monoxide (CO) poisoning was selected and Occupational Accident Tree Analysis (OATA) and Occupational Accident Component Analysis (OACA) techniques, which were solely used to investigate occupational accidents, were used with the new names Accident/Occupational Disease Tree Analysis (AOD TA) and Accident/Occupational Disease Component Analysis (AOD CA) to evaluate their applicability to investigate non-occupational accidents and occupational diseases. For this purpose, causes of CO penetration to victims’ room was assessed using gas tracking methods. Finally, Fuzzy Accident/Occupational Disease Tree/Component Analysis (FAOD TA and FAOD CA) techniques were developed and used for determining AOD RR in fuzzy environment. The results showed that the AOD RR obtained by AOD TA and AOD CA based on the average of experts’ personal opinions and consensus between experts, and AOD TA and AOD CA in a fuzzy environment were close to each other, with the power terminal and the power cable crossing route being the main routes of transmission and penetration of CO to the victims’ room. Also, the owner, contractor, tenant, and serviceman were responsible for the CO poisoning of victims. It can be concluded that any hole, crack, or fission in the building can result in CO penetration to the individuals’ living rooms, and gas tracking in early winter, especially in older buildings, plays a very significant role in preventing residents’ poisoning. Further, due to the uncertainty of AOD TA and AOD CA techniques, it is recommended to use FAOD TA and FAOD CA techniques for increasing the accuracy of the results. This will enhance the court and insurance companies’ trust in the opinions of accident investigation experts, decrease delays in the proceedings, and prevent any violation of the individual rights. 相似文献

When using a content-based lie detection tool, a decision regarding veracity is made by evaluating the presence of specific content criteria within the interviewee’s account. This evaluation can be achieved either by counting the frequency of occurrence of the criteria (frequency counts; FC) or by using a scale to rate the intensity at which they appear in the entire text (scale rates; SR). In the current study, we compared these two coding methods with respect to their accuracy in determining veracity, and their intercoder and test–retest reliabilities. Fourteen coders coded the presence of perceptual and contextual details in true and false statements, each used the FC method for one set of 30 statements and the SR method for another set of 30 statements. One month later, eight of the coders recoded 28 statements. Results showed a significant advantage for the FC method over the SR method. While the coders perceived the SR method as less time-consuming than the FC method, accuracy level as well as intercoder and test–retest reliabilities were higher for the FC than for the SR method. These findings suggest that when using a content-based lie detection tool, FC coding should be preferred over SR coding. 相似文献
