Addressing selective attrition in the enhanced response time‐based concealed information test: A within‐subject replication

The response time‐based concealed information test can reveal when a person recognizes a relevant item among other, irrelevant items, based on comparatively slower responding. Thereby, if a person is concealing the knowledge about the relevance of this item (e.g., recognizing it as a murder weapon), this deception can be revealed. A recent study, conducted online and using a between‐subject design, introduced a significantly enhanced version by including additional items in the task. While this modified version outperformed the original version, it also resulted in a much higher rate of participant dropouts (i.e., participants leaving the experiment's website without completing the task). The grave implication is that the perceived enhancement is perhaps merely due to selective attrition. Therefore, the current experiment replicates the original one, but using a within‐subject design. The results show that there is a large enhancement even when selective attrition is prevented.     

建议距离和线索丰富性对建议采纳的影响

基于社会判断理论,研究以80名大学生为被试,通过JAS范式考察了建议距离对建议采纳和自信心变化的影响以及线索丰富性在这一过程中的作用。结果发现随着建议距离的增加,建议权重仅在线索信息较丰富的情况下呈先增后减的倒U型趋势,而绝对观点转变和自信心变化均不受线索丰富性的影响,分别呈递增和递减趋势。即建议距离对不同建议采纳指标有不同影响,建议距离与建议权重之间存在倒U曲线关系且线索丰富性起到了调节作用。

The first direct replication on using verbal credibility assessment for the detection of deceptive intentions

Verbal deception detection has gained momentum as a technique to tell truth‐tellers from liars. At the same time, researchers' degrees of freedom make it hard to assess the robustness of effects. Replication research can help evaluate how reproducible an effect is. We present the first replication in verbal deception research whereby ferry passengers were instructed to tell the truth or lie about their travel plans. The original study found truth‐tellers to include more specific time references in their answers. The replication study that closely mimicked the setting, procedure, materials, coding, and analyses found no lie–truth difference for specific time references. Although the power of our replication study was suboptimal (0.77), Bayesian statistics showed evidence in favor of the null hypothesis. Given the great applied consequences of verbal credibility tests, we hope this first replication attempt ignites much needed preregistered, high‐powered, multilab replication efforts.     

Are you for real? Exploring language use and unexpected process questions within the detection of identity deception

The current study was to test whether reality monitoring and language use could distinguish identity liars from truth tellers when answering outcome questions and unexpected process questions. Truth tellers (n = 30) and liars (n = 30) discussed their identity in a recruitment interview. No differences emerged between truth tellers and liars in the details they provided. In terms of language use, liars used more positive language than truth tellers, whereas truth tellers used more cognitive process words than liars. However, neither were more pronounced when asking process questions. Overall, process questions elicited more cognitive process and cause words than outcome questions. Therefore, process questions may be able to contribute to the cognitive load approach. The findings suggest that reality monitoring may not be diagnostic when applied to identity deception. We discuss the language use differences in relation to impression management theory.     

Psychological Correlates of Perception of Sexual Intent in Women

Abstract

In a sample of 183 men and 186 women, the authors assessed (a) the relative contributions of gender and level of nonverbal social cues to the perception of a female actor's sexual intent during a videotaped social interaction with a man and (b) the association between those variables and personality traits implicated in faulty sexual-information processing. The authors assessed those variables while the participants viewed 1 of 3 film segments depicting a female-male interaction. The authors experimentally manipulated eye contact, touch, physical proximity, and female clothing. At all levels of those nonverbal cues, the men perceived more sexual intent in the female actor than did the women. The perception of the female actor's sexual intent increased as the nonverbal cues in the film segments were magnified: Both actors displayed more eye contact, touch, and physical proximity, and the female actor wore more revealing clothing. Relative to the women, the men demonstrated greater sexual preoccupation and reduced sociosexual effectiveness, variables associated with inferring greater sexual intent in the female actor.     

3～5岁儿童基于声音线索的情绪知觉

研究从言语的韵律和语义两条线索出发,试图探讨学前儿童基于声音线索情绪知觉的发展特点.实验一中,124名3～5岁儿童对男、女性用5种不同情绪(高兴、生气、害怕、难过和中性)的声音表达的中性语义句子进行了情绪类型上的判断.3～5岁儿童基于声音韵律线索情绪知觉能力随着年龄的增长不断提高,主要表现在生气、害怕和中性情绪上.不同情绪类型识别的发展轨迹不完全相同,总体来说,高兴的声音韵律最容易识别,而害怕是最难识别的.当韵律和语义线索冲突时,学前儿童更多地依赖韵律线索来判断说话者的情绪状态.被试对女性用声音表达的情绪更敏感.     

Verbal cues flexibly transform spatial representations in human memory

ABSTRACT

Humans possess a unique ability to communicate spatially-relevant information, yet the intersection between language and navigation remains largely unexplored. One possibility is that verbal cues accentuate heuristics useful for coding spatial layouts, yet this idea remains largely untested. We test the idea that verbal cues flexibly accentuate the coding of heuristics to remember spatial layouts via spatial boundaries or landmarks. The alternative hypothesis instead conceives of encoding during navigation as a step-wise process involving binding lower-level features, and thus subsequently formed spatial representations should not be modified by verbal cues. Across three experiments, we found that verbal cues significantly affected pointing error patterns at axes that were aligned with the verbally cued heuristic, suggesting that verbal cues influenced the heuristics employed to remember object positions. Further analyses suggested evidence for a hybrid model, in which boundaries were encoded more obligatorily than landmarks, but both were accessed flexibly with verbal instruction. These findings could not be accounted for by a tendency to spend more time facing the instructed component during navigation, ruling out an attentional-encoding mechanism. Our findings argue that verbal cues influence the heuristics employed to code environments, suggesting a mechanism for how humans use language to communicate navigationally-relevant information.     

Immediate and delayed recall of a small-scale spatial array

The study examined people's spatial memory of a small-scale array of objects. Earlier work has primarily relied on short-retention intervals, and to date it is not known whether performance is affected by longer intervals between learning and recall. In the present investigation, university students studied seven target objects. Recall was tested immediately after learning and after an interval of seven days. Performance was found to be similar in the immediate and delayed conditions, and the results suggested that recall was facilitated by egocentric and intrinsic cues. The findings are discussed with reference to recent investigations that have shown task parameters can influence spatial recall.
