Facilitating memory‐based lie detection in immediate and delayed interviewing: The role of mnemonics

We experimentally investigated how different mnemonic techniques employed in an interview conducted immediately after an event affected truth tellers' and liars' responses when they were interviewed again after a 2‐week delay. We also compared how verbal accounts changed over time within truth tellers and liars, and how consistent both groups were. Participants (n = 143) were shown a mock intelligence operation video and instructed either to tell the truth or lie about its contents in two interviews, one of which was immediately after watching the video and the other after a 2‐week delay. In the immediate interview, they were asked to provide a free recall and then asked to provide further information via one of three mnemonics: context reinstatement, sketch, or event‐line. In the delayed interview, they were asked to provide only a free recall. Truth tellers reported more visual, spatial, temporal, and action details than did liars both immediately and after a delay. Truth tellers experienced more of a decline in reporting details after a delay than did liars, and this decline was affected by the mnemonic used. Truth tellers thus showed, more than liars, patterns of reporting indicative of genuine memory decay. Liars produced patterns of a “stability bias” instead. Truth tellers and liars were equally consistent between their immediate and delayed statements.     

功能性近红外光谱技术在社会互动脑机制研究中的应用

功能性近红外光谱技术是一种以大脑组织中的血容和血氧为信息载体,通过测量大脑皮层中血容和血氧的分布和变化情况来了解局部脑活动的技术手段。近年来该技术在双脑研究非言语互动、言语互动、混合互动等社会互动脑机制领域做出了重要贡献。为了更清晰地揭示自然情境中社会互动的神经机制,未来尚需进一步改进近红外光谱技术本身,开发有效的数据分析方法,细化互动任务类型,丰富完善实验范式,促进多种脑成像技术的融合。     

The association of motor information and verbal information: a new perspective on the mechanism of the SPT effect

Current perspectives on the mechanism underlying the Subject Performed Task (SPT) effect have not yet reached a consensus. This study investigated whether the association between motor and verbal information is a key factor that explains the SPT effect. Experiment 1 and 2 tested whether motor and verbal retrieval memory performance were different when the association level was varied. Results showed that when subjects used low association learning materials, memory performance in either motor or verbal retrieval condition was significantly better than performance in the combined retrieval condition. Experiment 3 examined whether the level of association between motor and verbal information affects the SPT effect. Results revealed that the SPT effect disappeared when low association learning materials were used. Our findings imply that the high association level between motor and verbal information enables mutual activation of the two information types, leading to improved memory performance.     

Effects of homophobic name‐calling and verbal sexual harassment on substance use among young adults

Verbal aggression victimization, such as homophobic name‐calling, has been linked to heavier substance use among young people, but little longitudinal research has examined how different types of victimization may affect substance use or whether certain psychosocial factors moderate these risks. In a diverse cohort (N = 2,663), latent transition analysis was used to model heterogeneity in victimization (age 19) and substance use (age 20). Four victimization (high victimization, homophobic name‐calling only, verbal sexual harassment only, and low victimization) and three substance use (poly‐substance use, alcohol, and cannabis only, low all) classes were identified. The high victimization and homophobic name‐calling only classes had the highest probabilities of transitioning into the poly‐substance use class, and the high victimization class had the highest probability of transitioning into the alcohol and cannabis only class. The probability of transitioning into the low all substance use class was highest in the low victimization class and lowest in the high victimization class. For the high victimization class, greater depressive symptoms increased the odds, and better peer relationship quality decreased the odds, of transitioning into the poly‐substance use and alcohol and cannabis only classes. For the homophobic name‐calling only class, greater depressive symptoms increased the odds of transitioning into the poly‐substance use class. Homophobic name‐calling, alone or in combination with verbal sexual harassment, is a risk factor for escalating substance use in young adulthood, especially among victims with depressive symptoms.     

Direct verbal suggestibility: Measurement and significance

Hypnotic suggestibility is part of the wider psychological trait of direct verbal suggestibility (DVS). Historically, DVS in hypnosis has informed theories of consciousness and of conversion disorder. More recently it has served as a research tool in cognitive science and in cognitive neuroscience in particular. Here we consider DVS as a general trait, its relation to other psychological characteristics and abilities, and to the origin and treatment of clinical conditions. We then outline the distribution of DVS in the population, its measurement, relationship to other forms of suggestibility, placebo responsiveness, personal characteristics, gender, neurological processes and other factors, such as expectancy. There is currently no scale specifically designed to measure DVS outside a hypnotic context. The most commonly used and well-researched of the hypnosis-based scales, the Harvard Group Scale, is described and identified as a basis for a more broadly based measure of DVS for use in psychological research.     

Exploring cooperation and competition in the Centipede game through verbal protocol analysis

The Centipede game is an abstract model of reciprocal relationships in which two individuals alternate in helping each other at relatively small personal cost. Whereas mutual cooperation can benefit both individuals in the long run, a paradoxical but logically compelling backward induction argument suggests that cooperation is irrational. Empirical studies have reported reliable deviations from the non‐cooperative backward induction solution, but their exclusively quantitative methods allow only a limited range of predefined motives to be explored. Our study uses verbal (‘think aloud’) protocols and qualitative data analysis to identify motives for cooperation in the Centipede game. The results provide little evidence for sophisticated backward induction reasoning. Instead, a wide range of motives emerged, their relative saliences varying according to the stage of the game. Activity bias affected decisions mainly at the beginning of the game, whereas cooperative and altruistic social value orientations most frequently accounted for cooperation towards its natural end.     

谁该成为体验型产品网络评论的主角,图片还是文字?

图片、文字是体验型产品网络评论的两种主要形式,但关于两者对消费者影响的研究结论尚存在分歧。本研究基于解释水平理论,通过系列实验揭示了图片、文字评论在不同购买可行性情境下对消费者产品评价的影响,及产品类型(怀旧/非怀旧)的调节作用。结果表明:(1)购买可行性低情境下的消费者受文字评论的影响更大,而购买可行性高情境下的消费者受图片评论的影响更大(实验1a、实验1b和实验2);(2)购买怀旧产品时,购买可行性低情境下的消费者仍受文字评论的影响更大,而购买可行性高情境下的消费者受两类评论的影响无差异;购买非怀旧产品时,购买可行性高情境下的消费者仍受图片评论的影响更大,而购买可行性低情境下的消费者受两类评论的影响无差异(实验3)。本研究表明,当图片、文字评论与购买可行性在解释水平上一致时,影响力最大,且怀旧/非怀旧产品类型会调节这种效应。本研究还讨论了如何在实际中运用此结论。     

Numerical and verbal decision analysis: comparison on practical cases

Numerical decision analysis (NDA), derived from statistical decision theory, is very well known. Verbal decision analysis (VDA), oriented towards so‐called unstructured problems, where the qualitative and uncertain factors dominate, is a newer direction in decision theory and practice. Verbal and numerical decision analyses (DAs) have been compared in an experimental setting, with groups of students. This paper presents the results of a comparison in the context of live practical tasks. Both approaches were attempted on two comparable choices, facing both Russian and US government agencies, involving a choice between oil and gas transportation options. The resulting methodological insights are generalized into a systematic comparison of the strong and weak features of each approach. Copyright © 2000 John Wiley & Sons, Ltd.
