时间感知在跨期决策中的作用——时间决策模型的新探索

“时间”是跨期决策的“必需品”, 人们感知到的延迟时间决定跨期决策的结果。近年来, 研究者发现“时间长度感知”、“时间资源感知”和“时间框架感知”是时间感知作用于跨期决策的主要方式。时间感知的神经作用机制包含微观层面和宏观层面两种。“对数/指数时间折扣模型”、“感知时间基础模型”及“多模态漂移扩散模型”解释了时间感知的作用方式。然而, 现有理论模型还存在诸多局限, 主要包括“长短时距预测偏差”和“实际决策与预期决策偏差”两个方面。因此, 深入探讨时间感知影响跨期决策的基本方式, 分析现有理论模型的局限性并提出整合的机制框架具有十分重要的意义。未来研究亟需进一步整合时间感知的理论模型, 开展脑机制与应用方面的研究, 从深层揭露时间感知的作用本质, 帮助个人与社会更理性地决策。     

青少年时间态度与学业拖延的关系：成就动机的中介作用

采用青少年时间态度量表、成就动机量表和学业拖延问卷,对 733名中学生进行调查,旨在探究时间态度与学业拖延的关系,揭示成就动机在时间态度与学业拖延之间的中介作用机制。结果发现（1）过去消极、现在消极和未来消极与学业拖延呈显著正相关,过去积极、现在积极和未来积极与学业拖延呈显著负相关。（2）过去消极、现在消极和未来消极与成就动机呈显著负相关,过去积极、现在积极和未来积极与成就动机呈显著正相关;成就动机与学业拖延呈显著负相关。（3）成就动机在现在消极与学业拖延之间起部分中介作用,在未来积极、未来消极与学业拖延之间起完全中介作用。     

The Shared Values of Humanity and Its Philosophical Implications: From the Perspective of Civilization

The concept of the shared values of humanity, embodying the spirit of putting people first and solving real-life problems, is of great significance for constructing a new global order and building a human community with a shared future. The shared values of humanity respect the differences in understanding and realization paths of different civilizations, and seek common grounds with an inclusive and open attitude. The core socialist values are an embodiment and an extension of the shared values of humanity. The fine traditional Chinese culture has also laid a profound cultural basis for the pursuit of the shared values of humanity, enabling us to make up a better scheme for building a human community with a shared future from the perspective of civilization.     

Social Dominance and the Cultural Politics of Immigration

We argue that conflict over immigration largely concerns who bears the burden of cultural transaction costs, which we define as the costs associated with overcoming cultural barriers (e.g., language) to social exchange. Our framework suggests that the ability of native‐born citizens to push cultural transaction costs onto immigrant out‐groups serves as an important expression of social dominance. In two novel studies, we demonstrate that social dominance motives condition emotional responses to encountering cultural transaction costs, shape engagement in cultural accommodation behavior toward immigrants, and affect immigration attitudes and policy preferences.     

Manager–salesperson congruence in customer orientation and job outcomes: The bright and dark sides of leadership in aligning values

To create customer-oriented organizations, managers are often asked to promote a values-based vision. Yet, many managers struggle with transferring their values to employees making strategic value changes difficult. Despite this challenge, research has yet to demonstrate how managers effectively align values within the sales force, or the impact alignment has on job outcomes. Therefore, we develop and empirically test a conceptual framework to examine the role of transformational leadership in aligning salesperson customer orientation (CO) values. We find that transformational leadership is a strong mechanism in creating perceived value congruence, yet may have a surprising dark side. Results suggest that transformational managers achieve congruence by raising or, contrary to conventional wisdom, lowering salesperson CO values to meet the perceived values of the manager. Response surface modelling results support the importance of perceived manager values. Customer-oriented salespeople have higher job satisfaction and sales performance when they perceive their manager to also have high CO. When values are misaligned, job satisfaction increases more for low CO salespeople as perceptions of manager CO increase. Exploratory findings show that performance was higher under situations of perfect alignment but also under severe misalignment suggesting that values generate performance under complementary or supplementary conditions.     

根据血压昼夜节律选择服药时间控制血压晨峰

根据血压昼夜节律,观察给药时间对血压晨峰的影响。256例原发性高血压患者,经24h动态血压监测分为超杓型（n＝49）、杓型（n＝127）和非杓型（n＝80）3组;各组再分为清晨服药组和晚上服药组。用药6周,比较用药前后血压昼夜节律及血压晨峰的变化,发现在改变血压昼夜节律及降低血压晨峰方面,超杓型组清晨服药优于晚上服药,非杓型组晚上服药优于清晨服药;杓型组清晨服药与晚上服药均能降低晨峰值,提示根据个体血压昼夜节律选择服药时间能更好地控制血压晨峰。     

价值取向与社会距离影响经济决策的合作与冲突行为：Chicken Game的证据

采用Chicken Game博弈任务,考察了不同社会价值取向个体（亲社会者与亲自我者）在面对不同社会距离的博弈对手（朋友和陌生人）时表现出的合作与冲突行为。研究结果发现：（1）社会价值取向与社会距离交互影响个体的合作与冲突行为;（2）社会价值取向影响选择策略的反应时,亲社会者选择合作的反应时长于选择冲突的反应时,亲自我者选择合作与选择冲突的反应时没有显著差异;（3）无论对亲社会者还是亲自我者,反馈类型都显著影响个体的合作与冲突行为的选择率以及随后决策的反应时。上述结果表明,个体的合作或冲突行为,并非单一地受到社会价值取向的影响,更可能是受到个人因素（社会价值取向）与其他社会因素（比如,社会距离）的共同调节,并且在这一过程中个体会根据决策后反馈信息不断的调整自己的行为策略。
