Does inequity aversion depend on a frustration effect? A test with capuchin monkeys (Cebus apella)

Brosnan and de Waal (Nature 425:297–299, 2003) reported that if a witness monkey saw a model monkey receive a high-value food, the witness was more inclined to reject a previously acceptable, but low-value food. Later work demonstrated that this alleged inequity aversion might be due to frustration induced by switching subjects from their role as models receiving a high-value food to the role of witnesses receiving a low-value food. In the present study, pairs of female capuchins exchanged a token for either a high- or a low-value food without switching their model–witness roles. Witnesses could exchange a token for a low-value food after an adjacent model had exchanged a token for the same food (Equity Condition) or for a high-value food (Inequity Condition). Failure- and latency-to-exchange measures showed that witnesses were unaffected by the food type offered to models (no inequity aversion). Moreover, models were unaffected by their history of food type offered (no frustration). These results join earlier work suggesting that alleged inequity effects depend on frustration-induction procedures. Furthermore, inequity effects sometimes fail to emerge because frustration induction in nonhuman primates is labile. This study complied with protocols approved by the Italian Health Ministry and all procedures were performed in full accordance with the European law on humane care and use of laboratory animals.     

领导-部属交换（LMX）的回顾与展望

领导-部属交换理论从领导和部属的对偶关系中考察领导行为及其对下属的绩效、组织承诺等结果变量的影响。文章回顾了领导-部属交换的文献,对于它的概念、理论基础、结构、测量工具等进行了综合介绍,对不同测量工具的各自的特点以及它们之间的关系做了分析,接着总结了影响领导-部属关系的影响因素和结果变量以及与变革型领导的关系,最后提出未来研究应该加强从领导部属交换的发展阶段以及从部属或领导的角度来分析领导-部属交换理论     

Deadly combinations: how leadership contexts undermine the activation and enactment of followers’ high core self-evaluations in performance

Employees with high core self-evaluations (CSE) generally perform well in their jobs. The enactment of CSE in performance occurs within contexts, and leadership is one form of context that influences the activation and expression of CSE. Drawing on theories of CSE and leader–member exchange (LMX), we characterized the leadership context as the interaction between leader CSE and LMX quality. Examination of 173 followers and their 31 leaders in a manufacturing organization showed a positive association between follower CSE and performance when the context comprised high leader CSE and high LMX. Conversely, leadership contexts comprising high leader CSE and low LMX, or low leader CSE and high LMX, resulted in a negative relationship between follower CSE and performance. We also show that low CSE followers have relatively high performance under some circumstances. Thus, we contribute to understanding how some leadership contexts undermine high CSE followers’ performance and promote low CSE followers’ performance.     

家庭支持型主管行为对员工的影响与作用机制：基于元分析的证据

为厘清家庭支持型主管行为对员工的独特影响,并比较不同的作用机制,本研究对包含204个独立样本、340个效应值及91145名员工的164篇文献进行了元分析,结果发现：(1)与一般主管支持行为相比,家庭支持型主管行为对员工的任务绩效、创新行为和生活满意度有更强的积极影响。(2)工作对家庭冲突(资源视角)、领导-成员交换(交换视角)和情感承诺(情感视角)均能解释家庭支持型主管行为对员工的作用机制,并互为补充。具体而言,三者均能中介家庭支持型主管行为对任务绩效的影响;领导-成员交换和情感承诺在家庭支持型主管行为与创新行为间起中介作用;工作对家庭冲突和领导-成员交换则在家庭支持型主管行为影响生活满意度中发挥中介效应。研究结果为家庭支持型主管行为的影响效果提供了可靠结论,也有助于深入理解其作用机制。     

Social exchange relationships and exchange ideologies of employees and supervisors: A three-way interaction toward employee creativity

This study aims to better understand the effects of social exchange relationships between employees and their organizations (perceived organizational support [POS]), and their leaders (leader–member exchange [LMX]) on their creativity. To this end, we investigated how exchange ideologies of employees and supervisors affect the relationship between POS/LMX and employee creativity using a three-way interaction test. Building on the social exchange theory, the results from our sample of 254 leader–employee dyads indicated that the relationship between POS/LMX and employee creativity is significantly more positive for an employee with strong exchange ideology than for an employee with weak exchange ideology. Moreover, POS and LMX had the strongest positive relationships with creativity when both employees and supervisors had higher levels of exchange ideology. The implications of our results and future research directions are discussed.     

组织中的社会交换：由直接到间接

社会交换理论被引用来研究组织中的两种交换：员工与所在组织之间的交换——“感受组织支持”（POS）和员工与直接上司之间的交换——“领导—成员交换”（LMX）。以往的研究侧重于“直接交换”,即：从POS和LMX到员工工作产出的直接回归。该文以员工的组织情感承诺和工作满意感为中介变量,考察POS和LMX对员工工作产出的间接影响。在919份有效问卷的基础上,通过结构方程模型的比较,结果发现：组织情感承诺和工作满意感的确可以在POS和LMX与员工工作产出之间承担全部或部分中介的角色。这说明,员工与组织之间、上司与下属之间的交换只有小部分是“直接交换”,大部分则属于“间接交换”。最后,作者讨论了这些新发现的理论意义和实践意义,并指出了该研究的不足之处。     

Motivated information processing and group decision-making: Effects of process accountability on information processing and decision quality

Integrating dual-process models [Chaiken, S., & Trope, Y. (Eds.). (1999). Dual-process theories in social psychology. NewYork: Guilford Press] with work on information sharing and group decision-making [Stasser, G., & Titus, W. (1985). Pooling of unshared information in group decision making: biased information sampling during discussion. Journal of Personality and Social Psychology, 48, 1467-1478.], we predicted that groups with high epistemic motivation engage in more information-driven and less preference-driven interaction, and achieve better decisions. An experiment manipulating process accountability showed that groups under process accountability experienced greater need for more information, repeated unshared information more often, and more often chose the correct decision alternative. Mediation analysis established that epistemic motivation produced high quality decisions because it stimulated systematic information processing. Results also revealed that preference heterogeneity stimulated information-driven interaction and led to higher decision quality.     

Supervisor–Subordinate Relationship,Differentiation, and Employee Creativity: A Self‐Categorization Perspective

This study seeks to explore the effect of the quality of supervisor–subordinate relationship (i.e., leader–member exchange; LMX) on employee creativity by examining a moderated‐mediation model. The model focuses on the mediating role of perceived insider status and the moderating role of perceived LMX differentiation in influencing the mediation. Using a time‐lagged research design, we collected data from 358 supervisor–subordinate dyads in a large Chinese diversified company. As predicated, we found that (a) perceived insider status mediated the positive relationship between LMX and employee creativity; and (b) perceived LMX differentiation moderated the strength of the mediated relationship between LMX and employee creativity via perceived insider status, such that the mediated relationship is stronger under high‐perceived LMX differentiation than under low‐perceived LMX differentiation.     

Information elaboration and team performance: Examining the psychological origins and environmental contingencies

Information elaboration enables functionally diverse teams to transform their breadth of knowledge resources into actionable solutions to complex problems. The current study advances information elaboration theory and research in two ways. First, we identify how team ability and social motivation composition characteristics provide the psychological origins of complex information processing efforts. Second, we identify environmental turbulence as an important boundary condition, clarifying when information elaboration benefits team performance and when it does not. These ideas were tested in a sample of 4-person self-managed teams (N = 68) which were functionally diverse and performed a cooperative strategic decision-making task. Results indicate that cognitive ability equips teams with the “can do” ability for complex elaboration efforts through emergent team mental models, whereas low preferences for self-reliance provide the “will do” motivation for in-depth information exchange through collective leadership. In turn, teams benefited from information elaboration in turbulent but not stable environments.
