Interpersonal trust and market value moderates the bias in women’s preferences away from attractive high-status men

Women appear to exhibit a subtle reluctance to engage in long-term relationships with physically attractive, high-status men. We propose that this bias away from men of very high market value is based on fear that these males may desert a relationship and also on the comparative self-perceived market value of the women. Therefore, interpersonal trust and perceived market value should moderate the extent of this counterintuitive bias. To test this proposal, we asked women with varying levels of interpersonal trust and self-perceived desirability to consider physically-attractive and physically-average men of high, medium and low socioeconomic status and rate each in terms of attractiveness as a long-term partner. Results showed that women’s perceptions of their own desirability and their level of trust predicted their ratings of men with high-value in the mating market, and that women with high levels of both desirability and trust were less likely to show a bias away from high-value men. Interpersonal trust and desirability moderate the degree to which women find physically attractive men attractive as potential partners.     

基于熟悉性的项目间语义关系再认

在项目间语义关系的熟悉性研究中, 一个关键问题是熟悉性效应依赖于哪种信息的加工, 关系概念还是抽象结构?研究通过两个实验, 借助无线索回忆再认范式(the recognition without cued recall paradigm, 简称RWCR范式)和四词类比材料, 采用混合设计, 直接分离与比较关系概念和抽象结构的加工对RWCR效应的影响。结果发现, 关系概念作为测验线索能够引发显著RWCR效应, 但仅仅学习关系概念却不能;只有学习关系概念的结构化材料时, 才能引发显著RWCR效应。该结果表明, 项目间语义关系的熟悉性过程与结构信息有关。     

短时间延迟条件下错误记忆的遗忘

两个实验中,使用DRM范式考察了短时间延迟条件下错误记忆的遗忘效应。实验一发现对两种关键项目的错误再认均随着时间延迟（即时、半小时和1个小时）的增加而提高,而在将时间变量由实验一中的被试内设计变为实验二中的被试间设计后,发现对两种关键项目的错误再认随着时间而发生不同的变化,表现为对关键诱饵的错误再认保持稳定而对中关联词的错误再认依然有所提高。说明错误记忆很顽固,一旦产生便很难衰退,当消除了其他干扰因素的潜在影响后,即使是在很短暂的测验时间延迟条件下,它至少是保持稳定的,不会随着时间而发生减弱。此外还发现了关联性和测验情境与测验时间延迟之间的交互影响,表现为对关键诱饵的错误再认受测验时间延迟的影响较小,受测验情境的影响较大;而对中关联词的错误再认则受测验时间延迟的影响较大,受测验情境的影响较小     

Conscious Postural Control During Standing on Compliant Surface by Older Adults

This study examined the real-time objective measurement of conscious postural control (“reinvestment”) in older adults when standing on a compliant surface using electroencephalogram (EEG) coherence. Twenty-nine older adults participated in the study and their Alpha2 T3-Fz and Alpha2 T4-Fz EEG coherence during standing at three different positions on foam including wide-base standing on foam (WBF), narrow-base standing on foam (NBF) and tandem standing on foam (TAF) were measured. Participants were also required to respond to a Visual Analog Scale (VAS) to determine their perceived task difficulty after each standing position. Three 2?×?3 (Groups[low reinvestor, high reinvestor]?×?Standing positions[WBF, NBF, TAF]) analysis of variance (ANOVA) with repeated measures were conducted to determine differences between high and low reinvestors in three standing positions (WBF, NBF, TAF) at the primary outcome measures. The main effects of standing positions at VAS and Alpah2 T3-Fz EEG coherence were discovered but without interaction. The results suggested that when standing task difficulty increased, older adults generally elevated their real-time conscious postural control together with perceived task difficulty. It implicates that Alpha2 T3-Fz EEG coherence can be considered as a real-time objective conscious postural control measurement during balance assessment and rehabilitation if further large-scale studies could find its discriminative power between high and low reinvestors.     

预警和呈现时间对错误再认和错误回忆的影响

采用DRM范式,通过两个实验探讨了学习阶段的预警和词表呈现时间对错误再认与错误回忆的影响异同以及其发生作用的可能条件.采用视觉-视觉通道的学习-测验模式,实验1使用再认测验,结果发现呈现时间对错误再认不存在影响,而预警提示有效地降低了错误再认;实验2使用回忆测验,依然没有发现呈现时间对错误回忆的影响效应,预警的效应也消失.以上结果表明:(1)预警对错误回忆的影响受到编码时呈现通道的影响,视觉编码条件下预警效果甚微,而错误再认则无此通道效应;(2)呈现时间的较大变化可同时促进激活与监测过程,错误记忆效应的大小是激活与监测双加工过程此消彼长的交互作用结果.     

内观疗法对情绪体验影响的ERP研究

采用事件相关电位技术(ERPs)考察内观疗法对情绪体验影响的变化特点,以探明内观疗法是否引起情绪体验的变化。结果表明,内观组在400-1100ms平均波幅显著大于对照组,在内观组和对照组间,出现了显著的组间差异。由此得出结论,说明了内观疗法对情绪体验产生了影响,主要体现在情绪体验的深度与弥散性上。     

Perceptions of accuracy and effort of decision strategies

A critical tenet of cost-benefit theories of decision strategy choice is that decision makers’ perceptions of accuracy and effort determine strategy selection. However, little research has been conducted on human perceptions of decision strategy accuracy and effort. Instead, researchers have substituted deductively derived inferences on strategy accuracy and effort for perceptions in interpreting decision processes. In this study, we used a survey to study perceptions of decision strategies. The results indicate that participants as a group understood the accuracy and effort dimensions of decision strategies. The participants’ perceptions of the accuracy and effort of various decision strategies largely agreed with researchers’ deductions. However, there was substantial variation across individuals in perceptions of various decision strategies and in the composition of efficient frontiers of decision strategies.     

Rethinking procrastination: positive effects of "active" procrastination behavior on attitudes and performance

Researchers and practitioners have long regarded procrastination as a self-handicapping and dysfunctional behavior. In the present study, the authors proposed that not all procrastination behaviors either are harmful or lead to negative consequences. Specifically, the authors differentiated two types of procrastinators: passive procrastinators versus active procrastinators. Passive procrastinators are procrastinators in the traditional sense. They are paralyzed by their indecision to act and fail to complete tasks on time. In contrast, active procrastinators are a "positive" type of procrastinator. They prefer to work under pressure, and they make deliberate decisions to procrastinate. The present results showed that although active procrastinators procrastinate to the same degree as passive procrastinators, they are more similar to nonprocrastinators than to passive procrastinators in terms of purposive use of time, control of time, self-efficacy belief, coping styles, and outcomes including academic performance. The present findings offer a more sophisticated understanding of procrastination behavior and indicate a need to reevaluate its implications for outcomes of individuals.     

SEX DIFFERENCES IN PERSUASIBILITY FACTORS AMONG CHINESE1

Différences selon le sexe dans les facteurs de sensibilité à la persuasion chez des sujets chinois. — Plusieurs analyses factorielles distinctes ont été faites à partir des notes de sensibilité à la persuasion d'adolescents chinois, filles et garçons. Pour les garçons, trois facteurs émergent: le premier est relatif aux aux questions qui ne sont ni idéologiques, ni personnelles, le second aux questions idéologiques et le troisième, aux questions personnelles. Pour les filles, quatre facteurs ont pu être identifiés: L'un semble exprimer un certain ressentiment contre L'autorité masculine, le second est semblable au facteur idéologique trouvé chez les garçons; les deux derniers indiquent une sensibilité, L'un aux effets de priorité, L'autre, aux effets de récence. Les différences selon le sexe que L'on a constatées dans les facteurs, semblent être le reflet des différences dans les normes prescrites à L'un et L'autre sexe dans la culture chinoise traditionnelle.
