“行高人非”还是“见贤思齐”？职场上行比较对员工行为的双刃剑效应

本研究基于压力认知评估理论,从理性认知视角探讨了职场上行比较存在的提升自我和贬损他人效应,以及驱动不同路径效应生效的边界条件和传导机制。本研究通过轮询设计,在3个时间点收集了来自60个团队240位成员的720份人际配对样本,并采用社会关系模型分析数据得出以下结论:在低水平绩效证明目标导向情况下,员工倾向于将上行比较对象评估为挑战,进而激发员工向上行比较对象的学习行为;相反,在高水平绩效证明目标导向情况下,员工倾向于将上行比较对象评估为威胁,进而驱使员工采取针对上行比较对象的社会阻抑。

顾客授权行为对员工职业成长的影响：自我决定理论视角

聚焦于顾客授权行为这一概念, 以自我决定理论为基础, 分别引入基于组织的自尊作为中介变量和职业中心性作为调节变量, 探讨了顾客授权行为对一线服务员工职业成长的影响机制和作用边界。通过一项三阶段的时间滞后研究设计, 获取了245份有效样本, 结果显示: (1)顾客授权行为对员工职业成长具有显著的正向影响; (2)基于组织的自尊在顾客授权行为与员工职业成长之间起着部分中介作用; (3)职业中心性对顾客授权行为与基于组织的自尊的作用关系具有正向调节作用: 当员工职业中心性水平较高时, 顾客授权行为对基于组织的自尊的正向影响更强; (4)职业中心性进一步调节顾客授权行为通过基于组织的自尊对职业成长的间接影响: 当员工职业中心性水平较高时, 顾客授权行为通过基于组织的自尊对职业成长的正向效应会增强。     

The visual field paradox: a theoretical account on the reafference principle providing a common frame for the homogeneity and inhomogeneity of visual representation

Observations on the structure of the visual field and its central representation lead to a paradox. A functional dissociation is indicated in oculomotor or attentional control when different response modes are observed as a function of stimulus eccentricity. Alternatively, constancy of brightness throughout the visual field suggests its homogeneity. This paradox can be resolved, if perceptual and motor processes are not conceived of being controlled by separate neuronal mechanisms, but are interconnected within one frame of reference. The reafference principle allows to formulate such a common frame as it integrates afferent and efferent processes. On the basis of this concept, the visual field paradox can be interpreted as not being a paradox at all, but a necessary condition for optimal information processing.     

Phase transitions of Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass at pressures up to 27 GPa

The phase transitions of Zr_41.2Ti_13.8Cu_12.5Ni₁₀Be_22.5 bulk metallic glass have been investigated under high pressures and at room temperature. Direct resistance measurements in a diamond anvil cell provide evidence of a reversible transition between amorphous and crystalline phases; crystallization events occurred at 24 and 26.2 GPa on uploading, and crystalline-to-amorphous phase transitions were observed at 16 and 10.6 GPa on downloading. The phase transitions were confirmed by transmission electron microscopy observations.     

Refining the two‐parameter testlet response model by introducing testlet discrimination parameters

For testlet response data, traditional item response theory (IRT) models are often not appropriate due to local dependence presented among items within a common testlet. Several testlet‐based IRT models have been developed to model examinees' responses. In this paper, a new two‐parameter normal ogive testlet response theory (2PNOTRT) model for dichotomous items is proposed by introducing testlet discrimination parameters. A Bayesian model parameter estimation approach via a data augmentation scheme is developed. Simulations are conducted to evaluate the performance of the proposed 2PNOTRT model. The results indicated that the estimation of item parameters is satisfactory overall from the viewpoint of convergence. Finally, the proposed 2PNOTRT model is applied to a set of real testlet data.     

探寻理论化的德性伦理思想的复兴之路

20世纪五六十年代之后,西方德性伦理的复兴成为当代伦理学发展的前沿领域。在德性伦理思想的复兴中,主张理论化的德性伦理思想与早期反理论化的伦理思想有着重要的区别。努斯鲍姆、斯洛特、赫斯特豪斯等人认为,自近代以来,德性的失落与现代道德哲学中理性没有真正地充分发挥其本来作用有关。他们就此批判功利主义,力主伦理理论化的思想,开创了理论化的德性伦理思想的复兴之路。     

Ceci n'est pas la mort: Evidence for the recruitment of self‐reference from surrealistic art under mortality salience

Previous research has demonstrated that death reminders influence how we perceive art. In the context of terror management theory, this has been explained by the death‐transcending quality of art to convey cultural meaning. In two studies, we examined psychological and neurocognitive responses to naturalistic and surrealistic art when death was primed. We found that naturalistic paintings were evaluated similarly in terms of personal reassurance in both mortality salience and control condition, whereas surrealistic paintings were evaluated as more reassuring in the mortality salience condition than in the control condition. Using high‐field functional magnetic resonance imaging in a second study, we found a similar pattern of results, showing specific activation in the precuneus, a brain area associated with self‐related operations, in all prime conditions for the viewing of naturalistic paintings, but only in the death and disgust prime conditions when viewing surrealistic paintings. Our results suggest motivated self‐reference when viewing both naturalistic and surrealistic artworks under mortality salience. Copyright © 2014 John Wiley & Sons, Ltd.     

重新检视工作记忆在视觉搜索中的作用

视觉搜索是人类从作用于视觉系统的大量信息中选择相关信息进入信息加工系统的一种认知功能, 同时也是研究选择性注意的一种常用范式。工作记忆作为一种服务于当前任务信息的存储与加工的认知系统, 在视觉搜索过程中扮演着关键角色。为了深入了解工作记忆在视觉搜索过程中的作用机制, 在梳理已有成果的基础上, 分别从工作记忆对靶子模板的储存、视觉搜索项目与靶子模板在工作记忆中的匹配及工作记忆对已检测过搜索项目的记忆三个方面进行综述。最后结论表明工作记忆确实在视觉搜索过程中起作用, 但其作用机制仍存在较多争议。     

工作记忆表征捕获眼动中的颜色优先性

刺激属性所具有的引导效力在工作记忆表征自上而下地引导注意捕获过程中起重要作用, 已有研究表明工作记忆表征的颜色属性在引导注意时具有一定的优势。研究采用工作记忆任务与视觉搜索任务相结合的双任务范式, 结合眼动追踪技术, 通过设置具有较强引导效力的颜色属性与朝向属性进行直接竞争的实验条件, 进一步考察工作记忆表征的颜色属性是否依然具有优先性。实验1发现工作记忆表征的颜色属性与朝向属性同时竞争眼动捕获时, 颜色属性表现出较强的优势, 而朝向属性单独呈现时并未表现出任何捕获效应。实验2与3进一步证实了颜色属性捕获眼动的优先性, 即当颜色属性在面临作为靶子属性的朝向属性的竞争时, 依然能捕获更多的注视点。这些结果直接证实了工作记忆表征的颜色属性在工作记忆表征的捕获眼动的过程中具有较强的引导效力, 相对于其他刺激属性(如朝向、形状)更具有优先性。
