目标设置过程的理性特征分析

本文运用个案研究方法 ,从人类理性的角度分析了企业在不同的生产经营条件下的目标设置方式 ,发现不确定性和目标难度对管理者的目标设置过程有很大的影响。在确定的 ,且任务较容易的情况下 ,目标设置是以一种与理性期望模型相一致的方式进行的 ,而在高度不确定的条件下 ,管理者则倾向于采用渐进适应的模式设置目标。对管理者的经营活动作进一步深入的分析发现 ,在高难度的任务目标情景中 ,决策者更多地从战略的层次 ,而不是从具体的层次上寻求实现目标的途径 ,从而提出了目标难度与实绩的“策略搜索层次”假设     

Ethical Leadership: An Integrative Review and Future Research Agenda

Over the past decade, ethical leadership has increasingly become one of the most popular topics in the areas of leadership and business ethics. As a result, there now exists a substantial body of empirical research addressing ethical leadership issues, but the findings reported by this body of research are highly fragmented. The topic has advanced to the stage where a review and synthesis of existing literature can provide great value and help move the scholarly conversation forward. The primary purposes of this article are to (a) review empirical findings from the ethical leadership literature utilizing a framework consisting of the antecedents, mediators, moderators and outcomes of ethical leadership, and (b) suggest a set of interesting research opportunities, thereby facilitating future investigation. We base our synthesis on a review of 62 empirical studies on ethical leadership that were published between 2005 and mid-2015.     

Modelling individual difference in visual categorization

Recent years has seen growing interest in understanding, characterizing, and explaining individual differences in visual cognition. We focus here on individual differences in visual categorization. Categorization is the fundamental visual ability to group different objects together as the same kind of thing. Research on visual categorization and category learning has been significantly informed by computational modelling, so our review will focus both on how formal models of visual categorization have captured individual differences and how individual difference have informed the development of formal models. We first examine the potential sources of individual differences in leading models of visual categorization, providing a brief review of a range of different models. We then describe several examples of how computational models have captured individual differences in visual categorization. This review also provides a bit of an historical perspective, starting with models that predicted no individual differences, to those that captured group differences, to those that predict true individual differences, and to more recent hierarchical approaches that can simultaneously capture both group and individual differences in visual categorization. Via this selective review, we see how considerations of individual differences can lead to important theoretical insights into how people visually categorize objects in the world around them. We also consider new directions for work examining individual differences in visual categorization.     

Visual pattern memory requires foraging function in the central complex of Drosophila

The role of the foraging (for) gene, which encodes a cyclic guanosine-3',5'-monophosphate (cGMP)-dependent protein kinase (PKG), in food-search behavior in Drosophila has been intensively studied. However, its functions in other complex behaviors have not been well-characterized. Here, we show experimentally in Drosophila that the for gene is required in the operant visual learning paradigm. Visual pattern memory was normal in a natural variant rover (for(R)) but was impaired in another natural variant sitter (for(S)), which has a lower PKG level. Memory defects in for(S) flies could be rescued by either constitutive or adult-limited expression of for in the fan-shaped body. Interestingly, we showed that such rescue also occurred when for was expressed in the ellipsoid body. Additionally, expression of for in the fifth layer of the fan-shaped body restored sufficient memory for the pattern parameter "elevation" but not for "contour orientation," whereas expression of for in the ellipsoid body restored sufficient memory for both parameters. Our study defines a Drosophila model for further understanding the role of cGMP-PKG signaling in associative learning/memory and the neural circuit underlying this for-dependent visual pattern memory.     

变革型领导力和交易型领导力：团队绩效的预测指标

在高不确定,高度竞争,高度挑战的任务情景下,领导力在团队中将扮演怎样的角色？变革型领导力与交易型领导力又是如何预测团队任务绩效的？为了回答这些问题,该研究对130名学生被试,31个团队,用ERP沙盘模拟游戏来进行模拟实验。通过高度模拟现实中企业经营的情景,从而提高实验结果的外部效度。实验结果表明,变革型领导力与交易型领导力都能够积极地预测团队任务绩效,消极领导力与任务绩效呈负相关,虽然并没有达到统计学显著水平,但研究结果的方向都支持了实验假设。     

品牌形象的消费行为学研究

品牌形象是消费者头脑中与某一品牌相关联的属性集合和相关联想,是消费者对品牌的主观反映。作者在介绍有关国内外从消费行为学的角度进行品牌形象研究的基础上,就品牌形象的消费行为学研究提出了一些新的思路。     

组织决策的影响力分布特征及中英比较

本研究深入分析了组织内部各层次及外部机构对 1 8项决策的影响力。结果指出 :①我国企业存在着四种高层管理与中层管理的决策分工协作模型 ,即高层主导决策、中层自主决策、共同决策及层次决策模型 ,这说明我国企业中层管理的作用得到了加强 ,他们对决策的影响高于英国企业。②中国企业中 ,工人和基层管理的影响力普遍较小 ,尤其是在短期决策上 ,他们的影响力显著地小于英国企业。③中、英两国企业工会的影响力都很小 ,没有显著差别。但是从阻止力上分析 ,英国企业工会的作用显著地大于中国企业。这说明阻止力是一种独特的影响决策的方式 ,需要进一步的研究。     

脱贫内生动力机制的质性探究

内生动力是世代贫困个体得以脱贫的核心心理资源。当前, 对脱贫的内生动力仍然缺乏系统性的解释框架。文章以脱贫的内生动力为切入点, 基于内生和外生融合性视角, 采用基于深度访谈的扎根理论方法, 运用强度抽样的策略, 以海南岛某深度贫困村的成功脱贫个体(7人)、世代贫困个体(10人)及扶贫干部(4人)为研究对象, 构建出世代贫困家庭的整体内生动力资源枯竭模型。研究表明：1)以消极的价值观、消极的自我观和被动脱贫的行为倾向为主体的“三因素洋葱模型”是世代贫困个体的消极内在驱动力; 2)作为社会心理动力的控制感缺失是引致世代贫困个体内生动力匮乏的重要诱因, 而贫困个体缺少市场理性及扶贫的运动式治理可能是导致控制感缺失的外部肇因; 3)家长亲职能力在家庭内部建设能力培植子代内生动力的过程中起着中间作用, 即家庭内部建设能力可促进家长亲职能力的提高, 进而激发子代脱贫的内生动力。     

资源两难问题的研究及其新进展

作为多人社会两难问题的基本范式之一,近年来资源两难问题引起了包括社会学家、经济学家和心理学家在内诸多领域研究者越来越多的关注。文章介绍了资源两难问题的定义、特点、研究意义并总结了以往的研究成果,着重介绍了Samuelson和Messick于1994年提出的资源两难决策模型。在此基础上进一步指出以往研究存在的一些不足,如忽视了对不确定性的研究等。文章最后指出了近年来有关资源两难问题的研究在心理学界的发展,并提出了对以后研究的一些建议。     

哀伤研究：新的视角与理论整合

哀伤（bereavement）研究长期以来都依循“悲伤过程假设（griefworkhypothesis）”,但20世纪80年代后其强调“与逝者分离”的基本假设受到挑战,界定的模糊也使得实证研究工作难以进行。当代研究者从依恋理论、创伤研究、认知应对研究、情感的社会功能等视角多方面对哀伤领域进行深入探索并出现了一些整合性的理论模型,文中对有代表性的“依恋与哀伤双程模型”作了介绍,并对“悲伤过程假设”进行了重新检视
