Pavlovian reward learning elicits attentional capture by reward-associated stimuli

Feature–reward association elicits value-driven attentional capture (VDAC) regardless of the task relevance of associated features. What are the necessary conditions for feature–reward associations in VDAC? Recent studies claim that VDAC is based on Pavlovian conditioning. In this study, we manipulated the temporal relationships among feature, response, and reward in reward learning to elucidate the necessary components of VDAC. We presented reward-associated features in a variety of locations in a flanker task to form a color–reward association (training phase) and then tested VDAC in a subsequent visual search task (test phase). In Experiment 1, we showed reward-associated features in a task display requiring response selection and observed VDAC, consistent with most previous studies. In Experiment 2, features presented at a fixation display before a task display also induced VDAC. Moreover, in Experiment 3, we reduced the time interval between features and rewards so that features appeared after a task display and we obtained marginally significant VDAC. However, no VDAC was observed when features and rewards were simultaneously presented in a feedback display in Experiments 4 and 5, suggesting that a direct association between feature and reward is not sufficient for VDAC. These results are in favor of the idea that response selection does not mediate feature–reward association in VDAC. Moreover, the evidence suggests that the time interval of feature and reward is flexible with some restriction in the learning of feature–reward association. The present study supports the hypothesis that theories of Pavlovian conditioning can account for feature–reward association in VDAC.     

Activated or deactivated? Understanding how cognitive appraisals can drive emotional activation in the aftermath of daily work events

Introduction

Past research has highlighted the relevance of cognitive appraisals in the link events-emotions (e.g., appraisal of an event's importance and its pleasant or unpleasant valence). We hypothesized a 3-way interaction between affective events (hassles and uplifts), cognitive appraisals of importance and intrinsic pleasantness on emotional activation.

权重望寡：如何化解低地位领导的补偿性辱虐管理行为?

权力与地位来源不同且体验有别, 二者分离是常态。如果领导者手握权柄却缺乏相应的地位威望, 将限制其控制力, 产生潜在不良后果。基于低地位补偿理论, 构建一个两阶段调节的中介模型, 设计两项研究, 旨在探索领导者“权重望寡” (即权力高, 地位低)所诱发的负面领导行为及其干预机制。研究1揭示: 相对于权力与地位匹配, 领导者权重望寡诱发辱虐管理。研究2探索其成因, 显示: (1)自我损耗中介权重望寡与辱虐管理的关系; (2)领导者正念以及更高层领导信任联合调节自我损耗的中介效应。研究表明, 低地位领导在维护地位过程中产生的自我损耗是引发辱虐管理的主因, 同时辱虐管理强度因人而异, 适可而止, 自身正念和高层信任有助于限制其作为不良补偿手段的蔓延。研究拓展了低地位补偿理论的应用领域, 也为化解权力与地位分离带来的组织冲突提供管理启示。

Functional imaging of working memory and peripheral endothelial function in middle-aged adults

The current study examined the relationship between a prognostic indicator of vascular health, flow-mediated dilation (FMD), and working memory-related brain activation in healthy middle-aged adults. Forty-two participants underwent functional magnetic resonance imaging while completing a 2-Back working memory task. Brachial artery endothelial-dependent flow-mediated dilation (FMD) was assessed using B-mode ultrasound. The relationship between FMD and task-related brain activation in a priori regions of interest was modeled using hierarchical linear regression. Brachial FMD, was significantly related to reduced working memory-related activation in the right superior parietal lobule (β = 0.338, p = 0.027), independent of age, sex, systolic blood pressure, and full scale IQ (F(5, 36) = 2.66, p = 0.038). These data provide preliminary support for the association between a preclinical marker of endothelial dysfunction and cerebral hemodynamic alterations in healthy middle-aged adults. Considering the modifiable nature of endothelial function, additional investigations on the prognostic significance of FMD on future cognitive impairment are warranted.     

Abusive supervision and subordinate supervisor‐directed deviance: The moderating role of traditional values and the mediating role of revenge cognitions

This study examined the link between abusive supervision and subordinate supervisor‐directed deviance by focusing on the moderating role of traditionality and the mediating role of revenge cognitions directed towards supervisors. The results of analysing 283 supervisor–subordinate dyads in six private electronic companies and 222 supervisor–subordinate dyads in two state‐owned oil and gas companies in the People's Republic of China showed that abusive supervision was positively related to revenge cognitions directed towards supervisors and to supervisor‐directed deviance. In addition, traditionality moderated the above relationships such that they were stronger among low traditionalists than among high ones, while revenge cognitions mediated the main effect of abusive supervision and the interactive effect of abusive supervision and traditionality on supervisor‐directed deviance.

对疾病概念的建构论分析

对疾病的界定与解释是整个医学的核心与基础,尽管在不同历史时期都是本体论的疾病观占主流地位,但是纵观整个医学史,人们对疾病的不同界定充分证明了疾病概念问题上的建构论观点.医学上的建构论强调具体的社会环境、组织结构、价值信念、利益和权力关系等对疾病知识的影响.从建构论视角分析,"疾病"是一种功能性界定;疾病是一种价值判断;疾病是一种社会约定.     

英国关于生殖技术的伦理与法律规制研究

人工生殖技术触及到人类生命、人权问题的议题,须理性反思其发展结果是否侵害到人性的尊严及人权等可能性,面对生命本身的权利问题,构筑生命伦理观念,必须回溯探究人的尊严及生命权等人性最原始最基本的价值.提供人类在未采社会发展中所要采取的相应措施的理由,因为生殖技术的伦理与法律规范的作用与干预将使这些行为变成可能.
