Catching the liar as a matter of justice: Effects of belief in a just world on deception detection accuracy and the moderating role of mortality salience

Belief in a just world has been linked to high interpersonal trust and less suspicion of deception. We therefore predicted people with a strong dispositional belief in a just world to have low motivation to accurately detect deception. Accordingly, we hypothesized such a belief to be negatively related to accuracy in deception detection. Furthermore, research on Terror Management Theory has indicated that culturally shared values, such as justice, become more important after mortality salience. Thus, we assumed engaging in justice concerns after a death threat is especially relevant for people with a strong belief in a just world, and further, that accurate deception detection is a matter of justice. Based on this reasoning, we expected people with a strong belief in a just world to have an increased motivation to accurately detect deception after mortality salience. Consequently, we hypothesized dispositional differences in belief in a just world to be unrelated to accuracy in deception detection after mortality salience. In line with these predictions, our study revealed that participants with a strong (vs. weak) belief in a just world were worse in deception detection unless they had first been reminded of their mortality.     

Eliciting Intelligence Using the Scharff‐Technique: Closing in on the Confirmation/Disconfirmation‐Tactic

The current study examined interview techniques aimed at eliciting intelligence from human sources. We compared two versions of the Scharff‐technique to the Direct Approach (a combination of open and direct questions). The Scharff conditions, conceptualised into four tactics, differed only with respect to the ‘confirmation/disconfirmation‐tactic’. The participants (N = 90) received background information and took the role as a source in a phone interview. They were instructed to strike a balance between not revealing too little and too much information. As predicted, the Scharff‐technique resulted in more new information than the Direct Approach. Importantly, the sources interviewed by the Scharff‐technique perceived that they had revealed less new information than they objectively did, whereas the sources interviewed by the Direct Approach perceived that they had revealed more new information than they objectively did. Furthermore, the interviewer's information objectives were better masked with the confirmation‐tactic than with the disconfirmation‐tactic. The results highlight the Scharff‐technique as a promising human intelligence gathering technique. Copyright © 2014 John Wiley & Sons, Ltd.     

Using forced choice to test belief bias in syllogistic reasoning

In deductive reasoning, believable conclusions are more likely to be accepted regardless of their validity. Although many theories argue that this belief bias reflects a change in the quality of reasoning, distinguishing qualitative changes from simple response biases can be difficult (Dube, Rotello, & Heit, 2010). We introduced a novel procedure that controls for response bias. In Experiments 1 and 2, the task required judging which of two simultaneously presented syllogisms was valid. Surprisingly, there was no evidence for belief bias with this forced choice procedure. In Experiment 3, the procedure was modified so that only one set of premises was viewable at a time. An effect of beliefs emerged: unbelievable conclusions were judged more accurately, supporting the claim that beliefs affect the quality of reasoning. Experiments 4 and 5 replicated and extended this finding, showing that the effect was mediated by individual differences in cognitive ability and analytic cognitive style. Although the positive findings of Experiments 3–5 are most relevant to the debate about the mechanisms underlying belief bias, the null findings of Experiments 1 and 2 offer insight into how the presentation of an argument influences the manner in which people reason.     

Infants detect changes in everyday scenes: The role of scene gist

When watching physical events, infants bring to bear prior knowledge about objects and readily detect changes that contradict physical rules. Here we investigate the possibility that scene gist may affect infants, as it affects adults, when detecting changes in everyday scenes. In Experiment 1, 15-month-old infants missed a perceptually salient change that preserved the gist of a generic outdoor scene; the same change was readily detected if infants had insufficient time to process the display and had to rely on perceptual information for change detection. In Experiment 2, 15-month-olds detected a perceptually subtle change that preserved the scene gist but violated the rule of object continuity, suggesting that physical rules may overpower scene gist in infants’ change detection. Finally, Experiments 3 and 4 provided converging evidence for the effects of scene gist, showing that 15-month-olds missed a perceptually salient change that preserved the gist and detected a perceptually subtle change that disrupted the gist. Together, these results suggest that prior knowledge, including scene knowledge and physical knowledge, affects the process by which infants maintain their representations of everyday scenes.     

Sequential detection of learning in cognitive diagnosis

In order to look more closely at the many particular skills examinees utilize to answer items, cognitive diagnosis models have received much attention, and perhaps are preferable to item response models that ordinarily involve just one or a few broadly defined skills, when the objective is to hasten learning. If these fine‐grained skills can be identified, a sharpened focus on learning and remediation can be achieved. The focus here is on how to detect when learning has taken place for a particular attribute and efficiently guide a student through a sequence of items to ultimately attain mastery of all attributes while administering as few items as possible. This can be seen as a problem in sequential change‐point detection for which there is a long history and a well‐developed literature. Though some ad hoc rules for determining learning may be used, such as stopping after M consecutive items have been successfully answered, more efficient methods that are optimal under various conditions are available. The CUSUM, Shiryaev–Roberts and Shiryaev procedures can dramatically reduce the time required to detect learning while maintaining rigorous Type I error control, and they are studied in this context through simulation. Future directions for modelling and detection of learning are discussed.     

The edge of chaos: A nonlinear view of psychoanalytic technique

The field of nonlinear dynamics (or chaos theory) provides ways to expand concepts of psychoanalytic process that have implications for the technique of psychoanalysis. This paper describes how concepts of “the edge of chaos,” emergence, attractors, and coupled oscillators can help shape analytic technique resulting in an approach to doing analysis which is at the same time freer and more firmly based in an enlarged understanding of the ways in which psychoanalysis works than some current recommendation about technique. Illustrations from a lengthy analysis of an analysand with obsessive‐compulsive disorder show this approach in action.     

The effect of display timing on change blindness in pigeons (Columba livia)

Change blindness is a phenomenon in which even obvious changes in a visual scene may go unnoticed. Recent research has indicated that this phenomenon may not be exclusive to humans. Two experiments investigated change blindness in pigeons, using a variant of the widely‐used flicker task to investigate the influence of display timing on change blindness. Results indicate that the duration of time during which a stimulus display is visible influences change detection accuracy, with the effect due to additional search time. The results are discussed in relation to the value of comparative cognition and cross‐species investigations of behavior.     

视听时、空一致性对Pip-and-Pop效应的影响

多感觉整合遵循空间原则和时间原则, 有研究表明Pip-and-Pop效应产生的原因是多感觉整合, 那么Pip-and-Pop效应是否同样遵循空间原则和时间原则呢?本研究采用动态视觉搜索范式, 通过两个眼动实验考察空间一致性(实验1)和时间一致性(实验2)对Pip-and-Pop效应的影响。结果发现：(1)当视觉目标颜色变化伴随一个同侧的听觉刺激时所产生的Pip-and-Pop效应最大, 对侧条件没有发现Pip-and-Pop效应。(2)视听刺激同时呈现所产生的Pip-and-Pop效应最大, 随视听刺激呈现时间间隔的增加Pip-and-Pop效应逐渐减弱直至消失。结果表明, 视听时、空一致性对Pip-and-Pop效应具有调节作用, 这为多感觉整合在产生Pip-and-Pop效应中的作用提供了证据。     

目标决策还是动作诱发?动作反应对注意促进效应的影响

注意促进效应(ABE)指的是在双任务条件下, 伴随探测任务的目标刺激呈现的背景信息记忆成绩要优于伴随分心刺激呈现的背景信息记忆成绩的现象。以往研究主张, ABE的产生主要源于目标决策时所诱发的注意增强。但由于目标探测往往伴随着动作反应, 而已有研究发现, 动作反应就能直接诱发背景信息的记忆增强效应, 因此ABE也可能源于动作诱发的记忆增强效应。为此, 研究设置了NoGo目标探测条件与Go目标探测条件, 通过4个实验系统地探讨了动作反应与目标决策在ABE产生中的作用及关系。结果表明, Go目标探测条件下的ABE是稳定的, 但NoGo目标探测条件下的ABE会受到动作反应频率对分心词的影响。此外, NoGo目标探测跨条件的ABE也是非常稳定的。这些结果表明, 目标决策产生的注意促进作用是相对稳定的, 但ABE的产生更多是目标决策的促进作用与动作诱发的记忆增强效应动态权衡后的结果。
