The dimensions of deception detection: Self‐reported deception cue use is underpinned by two broad factors 下载免费PDF全文
Iain Hamlin Gordon R.T. Wright Sophie Van der Zee Stuart Wilson 《Applied cognitive psychology》2018,32(3):307-314
Many perceived cues to deception have been reported in the literature, but little attention has been paid to how they are combined when making deception judgments. The present research used a data‐driven approach to investigate how cues are integrated when evaluating veracity. Two hundred fifteen participants performed a deception detection task before completing a deception cue use questionnaire. A factor analysis of the questionnaire data produced two dimensions, one associated with nonverbal cues to anxiety and the other associated with detail and level of involvement. The present work extends our understanding of deception detection processes and underlines the importance of examining not only the cues that people use but also the way in which they use them. 相似文献

Cohen's κ, a similarity measure for categorical data, has since been applied to problems in the data mining field such as cluster analysis and network link prediction. In this paper, a new application is examined: community detection in networks. A new algorithm is proposed that uses Cohen's κ as a similarity measure for each pair of nodes; subsequently, the κ values are then clustered to detect the communities. This paper defines and tests this method on a variety of simulated and real networks. The results are compared with those from eight other community detection algorithms. Results show this new algorithm is consistently among the top performers in classifying data points both on simulated and real networks. Additionally, this is one of the broadest comparative simulations for comparing community detection algorithms to date. 相似文献

Background: Previous studies have reported that children score better in language
tasks using sung rather than spoken stimuli. We examined word detection ease in
sung and spoken sentences that were equated for phoneme duration and pitch
variations in children aged 7 to 12 years with typical language development
(TLD) as well as in children with specific language impairment (SLI ), and
hypothesized that the facilitation effect would vary with language abilities.
Method: In Experiment 1, 69 children with TLD (7–10 years old) detected words in
sentences that were spoken, sung on pitches extracted from speech, and sung on
original scores. In Experiment 2, we added a natural speech rate condition and
tested 68 children with TLD (7–12 years old). In Experiment 3, 16 children with
SLI and 16 age-matched children with TLD were tested in all four conditions.
Results: In both TLD groups, older children scored better than the younger ones.
The matched TLD group scored higher than the SLI group who scored at the level
of the younger children with TLD . None of the experiments showed a facilitation
effect of sung over spoken stimuli. Conclusions: Word detection abilities
improved with age in both TLD and SLI groups. Our findings are compatible with
the hypothesis of delayed language abilities in children with SLI , and are
discussed in light of the role of durational prosodic cues in words
detection. 相似文献

Mimicry and Investigative Interviewing: Using Deliberate Mimicry to Elicit Information and Cues to Deceit 下载免费PDF全文

We examined the effect of deliberate mimicry on eliciting (accurate) information and cues to deceit. Mimicry is considered to facilitate cooperation and compliance in truth tellers, whereas liars are constrained to provide detail. We therefore expected truth tellers to be more detailed than liars, particularly after being mimicked. A total of 165 participants told the truth or lied about a meeting they attended. During the interview, an interviewer mimicked half of the participants. Truth tellers were more detailed than liars, but only in the ‘mimicry present’ condition. Truth tellers also gave more accurate units of information than liars, and the difference was most pronounced in the ‘mimicry present’ condition. Mimicry as a tool for eliciting information and cues to deceit fits well with the emerging ‘interviewing to detect deception’ literature, particularly in the ‘encouraging interviewees to say more’ approach.

While many aspects of cognition have been investigated in relation to skilled music training, surprisingly little work has examined the connection between music training and attentional abilities. The present study investigated the performance of skilled musicians on cognitively demanding sustained attention tasks, measuring both temporal and visual discrimination over a prolonged duration. Participants with extensive formal music training were found to have superior performance on a temporal discrimination task, but not a visual discrimination task, compared to participants with no music training. In addition, no differences were found between groups in vigilance decrement in either type of task. Although no differences were evident in vigilance per se, the results indicate that performance in an attention-demanding temporal discrimination task was superior in individuals with extensive music training. We speculate that this basic cognitive ability may contribute to advantages that musicians show in other cognitive measures. 相似文献

采用经典的"学习–再认"范式,在测验阶段设置了目标探测的干扰任务,通过比较目标探测和分心拒绝是否会对记忆提取产生不同的影响,以进一步探讨提取干扰与再认记忆之间的关系。结果发现,无论对目标进行显性(实验1)还是隐性(实验2)的探测反应,目标探测下旧词的再认反应均要比分心拒绝下更优,表明外显记忆的提取也会受到注意资源的调节。但更为重要的是,在辨别力指数(d′)及判断标准(C)上的差异分析发现,目标探测并没有提高被试的再认水平,而是降低了被试的判断标准,使得被试在目标探测条件下更容易对词做出"旧"反应。这种反应倾向与目标探测的动作反应方式无关,也不受词汇的编码加工水平深浅的调节。由此可见,外显记忆提取并非完全的"自动化加工",仍会受到注意资源的调节。 相似文献

Visual working memory and threat monitoring: Spider fearfuls show disorder-specific change detection
Previous studies of biased information processing in anxiety addressed biases of attention and memory, but little is known about the processes taking place between them: visual working memory (VWM) and monitoring of threat. We investigated these processes with a change detection paradigm. In Experiment 1, spider fearfuls (SF) and non-anxious controls (NAC) judged two subsequently presented displays as same or different. The displays consisted of several pictures, one of which could depict a spider. In Experiment 2, SF and NAC, both without snake fear, were tested with displays including either a spider or a snake image to determine the material-specificity of biased VWM. Both groups showed increased change detection for threat images. This effect was significantly stronger in SF, for spider images only, indicating a threat-specific VWM bias. Thus, contrary to the assumptions made by most cognitive models of anxiety, an explicit memory bias was found. 相似文献

Basic results for conditional means and variances, as well as distributional results, are used to clarify the similarities and differences between various extensions of signal detection theory (SDT). It is shown that a previously presented motivation for the unequal variance SDT model (varying strength) actually leads to a related, yet distinct, model. The distinction has implications for other extensions of SDT, such as models with criteria that vary over trials. It is shown that a mixture extension of SDT is also consistent with unequal variances, but provides a different interpretation of the results; mixture SDT also offers a way to unify results found across several types of studies. 相似文献

A model for multiple-choice exams is developed from a signal-detection perspective. A correct alternative in a multiple-choice exam can be viewed as being a signal embedded in noise (incorrect alternatives). Examinees are assumed to have perceptions of the plausibility of each alternative, and the decision process is to choose the most plausible alternative. It is also assumed that each examinee either knows or does not know each item. These assumptions together lead to a signal detection choice model for multiple-choice exams. The model can be viewed, statistically, as a mixture extension, with random mixing, of the traditional choice model, or similarly, as a grade-of-membership extension. A version of the model with extreme value distributions is developed, in which case the model simplifies to a mixture multinomial logit model with random mixing. The approach is shown to offer measures of item discrimination and difficulty, along with information about the relative plausibility of each of the alternatives. The model, parameters, and measures derived from the parameters are compared to those obtained with several commonly used item response theory models. An application of the model to an educational data set is presented. 相似文献

Research suggests that word learning is an extended process, with offline consolidation crucial for the strengthening of new lexical representations and their integration with existing lexical knowledge (as measured by engagement in lexical competition). This supports a dual memory systems account, in which new information is initially sparsely encoded separately from existing knowledge and integrated with long-term memory over time. However, previous studies of this type exploited unnatural learning contexts, involving fictitious words in the absence of word meaning. In this study, 5- to 9-year-old children learned real science words (e.g., hippocampus) with or without semantic information. Children in both groups were slower to detect pauses in familiar competitor words (e.g., hippopotamus) relative to control words 24 h after training but not immediately, confirming that offline consolidation is required before new words are integrated with the lexicon and engage in lexical competition. Children recalled more new words 24 h after training than immediately (with similar improvements shown for the recall and recognition of new word meanings); however, children who were exposed to the meanings during training showed further improvements in recall after 1 week and outperformed children who were not exposed to meanings. These findings support the dual memory systems account of vocabulary acquisition and suggest that the association of a new phonological form with semantic information is critical for the development of stable lexical representations. 相似文献
