Train the Trainers: A First Step towards a Science‐Based Cognitive Lie Detection Training Workshop Delivered by a Practitioner

A training workshop utilising recent research in cognitive lie detection was designed and evaluated. A unique future of the training was that a practitioner (retired police detective) instead of scientists (e.g. the training developers) introduced the techniques. To evaluate the training, 27 experienced police detectives each interviewed one mock suspect (a truth teller or liar) before training, and another group of 23 experienced police detectives interviewed one mock suspect (a truth teller or liar) after training. The police detectives were free to interview the mock suspect in any way they felt appropriate, but those who had received training were asked to try to incorporate (some of) the taught techniques in their interviews. The detectives made veracity judgements, and the interviews were transcribed and coded for the amount of detail elicited and the questions asked. Training had a modest effect on the ability to distinguish between truths and lies but resulted in a higher percentage of appropriate questions asked. Trainees did not implement the taught techniques to an equal extent, but when they did, the techniques enhanced the elicitation of information. The training study also revealed challenges, particularly difficulty in implementing the taught techniques into practice and asking the right questions to elicit differences in detail between truth tellers and liars.

Manipulation and Deception

This paper introduces the category of ‘non-deceptive manipulation that causes false beliefs’, analyzes how it narrows the traditional scope of ‘deception’, and draws moral implications.     

儿童对汉字结构中语音线索的意识及其发展

采用纸笔测验探讨了二、四、六年级小学生读形声字的读音特点。结果表明,儿童对规则字的读音好于对不规则字和不知声旁字的读音。在对不熟悉字的读音中,儿童更多地利用汉字结构中的语音线索,更多地表现出能力差异。读音错误分析表明,随着年级的增高,儿童读音中非系统错误的比例减小,而声旁、类似错误的比例增加。     

Consumers' product evaluation: a study of the primary evaluative criteria in the precious jewellery market in the UK

It is normally argued that consumers make their purchase decisions on the basis of their evaluation of, and knowledge about, the product attributes. This paper reports findings from a research study, which was conducted to determine the nature and type of evaluative criteria used by an individual while purchasing a piece of precious jewellery. In doing so, the study looked into the significance of product category knowledge, brand familiarity and brand consciousness in product evaluation. A questionnaire was sent to 500 consumers of precious jewellery in five major cities of the UK. Results indicate that, in general, subjective attributes are more important for people buying precious jewellery than the objective attributes. The significance of specific attributes during product evaluation could vary according to one's level of product category knowledge, brand familiarity and brand consciousness. The paper discusses implications for the marketers. Copyright © 2001 Henry Stewart Publications.     

如何建立聊天机器人与用户间的数字治疗联盟：关系线索的作用

近年来,研究者们将“治疗联盟”(Therapeutic Alliance,TA)的概念与在线自助干预(Internet-based Self-help Interventions,ISIs)相结合,以解决ISIs中用户参与度较低的问题。这种在数字环境中形成的TA,被称之为“数字治疗联盟”(Digital Therapeutic Alliance, DTA)。随着人工智能的迅速发展,聊天机器人可模拟人类指导,相对于传统ISIs程序更易于与用户建立关系,可通过友好、尊重、倾听、鼓励、真诚、理解、信任这几个关系线索来促进DTA的发展,为解决用户低参与度的问题提供了一种新思路。未来的研究可从影响因素、ISIs技术迭代、测量规范、实验操纵等方面对DTA作进一步的探索。     

Variable Perception of White Noise in Ambiguous Phonetic Contexts: The Case of /p/ and /f/

The roles of spectro-temporal coherence, lexical status, and word position in the perception of speech in acoustic signals containing a mixture of speech and nonspeech sounds were investigated. Stimuli consisted of nine (non)words in which either white noise was inserted only into the silent interval preceding and/or following the onset of vocalic transitions ambiguous between /p/ and /f/, or in which white noise overlaid the entire utterance. Ten listeners perceived 85% /f/s when noise was inserted only into the silent interval signaling a stop closure, 47% /f/s when noise overlaid the entire (non)words, and 1% in the control condition that contained no noise. Effects of spectro-temporal coherence seemed to have dominated perceptual outcomes, although the lexical status and position of the critical phoneme also appeared to affect responses. The results are explained more adequately by the theory of Auditory Scene Analysis than by the Motor Theory of Speech Perception.     

儿童面对不同对象的欺骗表现及其相关的社会性特点

为进一步探讨儿童欺骗行为的表现及其影响因素,在研究一中,分别引入陌生的成年女性、成年男性、同龄女孩、同龄男孩等四种游戏对手,探讨159名幼儿园大班的儿童在面对不同对象的情况下外显欺骗行为是否发生变化？结果表明,被试性别、对手年龄和对手性别三因素之间交互作用显著,儿童更倾向于欺骗成年女性以及和自己性别不同的同伴。研究二采用儿童社会化量表进一步考察儿童欺骗行为和其它社会性特点的关联。结果表明隐蔽的动作欺骗和意志维度显著相关,外显的动作欺骗和好胜心维度显著相关,说谎和自我概念维度显著相关     

Evidence for distinct contributions of form and motion information to the recognition of emotions from body gestures

The importance of kinematics in emotion perception from body movement has been widely demonstrated. Evidence also suggests that the perception of biological motion relies to some extent on information about spatial and spatiotemporal form, yet the contribution of such form-related cues to emotion perception remains unclear. This study reports, for the first time, the relative effects on emotion recognition of inverting and motion-reversing patch-light compared to fully illuminated displays of whole-body emotion gestures. Inverting the gesture movies or playing them backwards significantly impaired emotion classification accuracy, but did so more for patch-light displays than for identical but fully illuminated movement sequences. This result suggests that inversion impairs the processing of form information related to the configuration of body parts, and reversal impairs the sequencing of form changes, more than these manipulations impair the processing of kinematic cues. This effect was strongest for inversion, suggesting an important role for configural information in emotion recognition. Nevertheless, even in combination these stimulus manipulations did not abolish above chance recognition of any of the emotions, suggesting that kinematics help distinguish emotions expressed by body gestures. Disproportionate impairments in recognition accuracy were observed for fear and disgust under inversion, and for fear under motion reversal, suggesting a greater role for form-related cues in the perception of these emotions.     

Assessment Criteria Indicative of Deception (ACID): an integrated system of investigative interviewing and detecting deception

This study describes the assimilation and validation of Assessment Criteria Indicative of Deception (ACID). ACID is derived from investigative interviewing, Criteria‐Based Content Analysis, Reality Monitoring, and interpersonal deception. Each component has been previously published. Thirty‐eight university undergraduates entered a professor's office and either stole an exam or replaced an exam that had been stolen previously. They were interviewed 1 week later with the Reality Interview, which is deliberately challenging and aims to enhance the detection of deception. Half responded honestly and completely; half distorted their responses to avoid incrimination. Incentives were provided. Honest responses were longer, more detailed, and contained more admissions of potential mistakes. Most importantly, honest respondents benefited from attempts to enhance recall, whereas these same attempts caused deceptive respondents to provide shorter, more repetitive statements. This is a promising technique; 33 of 38 cases were classified accurately. Discussion includes characteristics of deception, process of deception during an investigative interview, hypothetical interview strategies to facilitate the detection of deception, strengths and weaknesses of the study, and areas for future research.

The camera perspective bias: a case study

In this case study, we examined how variations of the camera perspective affect adults' assessment of veracity in a real‐life high‐stake situation; a masked male confessing to a very serious crime. The interview, conducted by one of Sweden's most awarded journalists, lasted 30 minutes and consisted of over 100 detailed questions about the crime. The interview was videotaped simultaneously by three cameras positioned at different locations, each taking a unique visual perspective. One camera focused on the suspect only, one on the interviewer only, and one equally on the suspect and the interviewer. Each videotape was shown to 32 adult observers (N = 96) who were asked to assess the suspect's veracity and to report subjective cues justifying their veracity assessment. The results confirmed the camera perspective bias, by showing that the observers in the ‘suspect only’ condition assessed the confession as significantly more reliable than did the observers in the ‘interviewer only’ condition. The observers reported that they relied heavily on verbal cues when assessing the confession, and particularly regarding confidence and consistency. Copyright © 2008 John Wiley & Sons, Ltd.
