BIS- and BAS-activation and study outcomes: A mediation study

Building on Gray’s original Reinforcement Sensitivity Theory, we examined how individual differences in students’ activation of the behavioral inhibition (BIS) and the behavioral approach (BAS) systems relate to overcommitment to one’s studies and study engagement, and how these two forms of heavy study investment relate to three academically relevant outcomes. Using data from 565 Dutch university students, structural equation modeling showed that BIS-activation was positively associated with overcommitment to one’s studies, which in turn was positively related to exhaustion and the intention to quit one’s studies. BAS-activation was positively associated with study engagement, which in turn was negatively related to exhaustion and the intention to quit, and positively related to academic performance. Bootstrapping techniques revealed a mediating role of the two forms of heavy study investment. Apparently, BIS- and BAS-activation are associated with heavy study behavior, student well-being, and study outcomes.     

Separating the confident from the correct: Leveraging member knowledge in groups to improve decision making and performance

Groups often struggle to distinguish expert members from others who stand out for various reasons but may not be particularly knowledgeable (Littlepage & Mueller, 1997). We examined an intervention designed to improve group decision making and performance through instructing group members to search for information they already possessed that was relevant to a problem. Participants estimated values and expressed their confidence in their estimates individually and then a second time either individually or in a group. This was done with or without the intervention. Results indicated that: (1) groups were more confident than, and out-performed, individuals, (2) group decision making was best captured by models predicting more influence for more accurate members when the intervention was used and more influence for more confident members in its absence, and (3) groups that received the intervention out-performed groups that did not.     

Do you see what I see? The effect of members’ cognitive styles on team processes and errors in task execution

This research investigates the effect of members’ cognitive styles on team processes that affect errors in execution tasks. In two laboratory studies, we investigated how a team’s composition (members’ cognitive styles related to object and spatial visualization) affects the team’s strategic focus and strategic consensus, and how those affect the team’s commission of errors. Study 1, conducted with 70 dyads performing a navigation and identification task, established that teams high in spatial visualization are more process-focused than teams high in object visualization. Process focus, which pertains to a team’s attention to the details of conducting a task, is associated with fewer errors. Study 2, conducted with 64 teams performing a building task, established that heterogeneity in cognitive style is negatively associated with the formation of a strategic consensus, which has a direct and mediating relationship with errors.     

The effects of team strategic orientation on team process and information search

We tested the effects of team strategic orientation on team member perceptions, work strategy and information search. In Experiment 1, 80 teams worked on a hidden profile decision-making task. A defensive team strategic orientation increased members’ perceptions of the problem’s scope, leading to a more process-focused work strategy and broader information search compared to an offensive team strategic orientation. When teams needed critical information from the environment, defensive teams outperformed offensive teams; offensive teams performed better when critical information resided within the team. In Experiment 2, these findings were replicated with 92 teams performing a different decision task. When making a second decision, half of the teams were led to change their strategic orientation; teams shifting from offense to defense altered their information search behavior more readily than did teams shifting in the opposite direction, suggesting an asymmetric adaptation effect.     

公交行业一线员工人格特质对工作绩效影响的实证分析--以工作态度作为调节变量

通过问卷调查法,探讨在工作态度调节下大五人格特质与工作绩效的关联。对1277名公交行业一线员工的研究结果表明：(1)人格特质与工作绩效有显著的相关,工作态度在这一关系中起到调节作用。在高工作态度中,人格特质与任务绩效联系较为紧密,工作绩效的良好预测指标是尽责性和外向性;在低工作态度中,人格特质与关系绩效联系较为紧密,工作绩效的良好预测指标是宜人性和外向性。(2)在高工作态度的环境中,人们更看重工作的完成;在低工作态度的环境中,人们更看重关系的协调。工作态度调节着人格特质对工作绩效的影响。     

真实火灾和模拟火灾情境下小鼠的逃生决策比较*

探讨并比较真实火灾和模拟火灾情境下小鼠是否采用直觉性逃生决策。研究包括一个预备训练和两个主实验。预备训练的目的：首先训练小鼠获得有关迷宫路线及出口的经验,然后再经过遗忘处理使它们遗忘相关经验。两个主实验均采用3(情境：真实火灾,模拟火灾,普通情境)×2(记忆：遗忘前和遗忘后)混合实验设计,因变量均为逃生决策。实验组被试为72只经过训练的小鼠,控制组为24只未经过训练的小鼠。通过考察小鼠在不同情境和不同记忆条件下的逃生时间和对逃生出口的选择探测并比较真实火灾和模拟火灾情境下小鼠的逃生决策差异。主要结果：(1)实验组在真实火灾情境下的逃生时间无论遗忘前后都明显比模拟火灾情境下短;(2)实验组在真实火灾和模拟火灾情境下的逃生时间都明显比控制组短;(3)当熟悉和陌生出口均开启同时熟悉出口处有烟雾条件下,真实火灾组在遗忘前后均倾向于选择熟悉出口逃生,其他两组则倾向于选择陌生出口离开。结论：真实火灾和模拟火灾情境下小鼠的逃生决策存在明显差异：真实火灾情境下受过训练的小鼠倾向于直觉性逃生决策;模拟火灾情境下受过训练的小鼠不倾向于直觉性逃生决策。     

An Exploratory Assessment of Sales Culture Variables: Strategic Implications Within the Banking Industry

Growing, or even simply sustaining, profitability in today's rapidly changing environment is a daunting task. Today's firm must contend with increasing competition, changing customer requirements, and unprecedented technological change. Further, changing government regulations, such as the recent wave of deregulation, have dramatically changed the way business has traditionally been done in certain industries. In such a turbulent environment many firms have discovered that a total organizational sales effort is necessary. For many firms, this means a paradigm shift that involves strengthening their sales culture.

The purpose of this study is to empirically examine the sales culture (SC) concept and discuss its importance in contemporary business strategy. First, we will discuss market orientation from a corporate culture perspective. Second, the sales culture component of a market orientation will be defined and examined. Third, an exploratory investigation of constructs associated with sales culture will be investigated using an example taken from an industry that is experiencing rapid change, the banking industry. Finally, strategic implications, limitations and suggestions for future research will be shared.     

Individual differences in susceptibility to infection and illness following respiratory virus challenge

Abstract

The aim of the present research was to investigate whether susceptibility to experimentally-induced respiratory virus infections and illness is related to measures of personality, physiological state, performance efficiency, and subjective ratings of alertness and motivation obtained prior to virus challenge. Two studies, using different viruses, showed that volunteers who subsequently developed colds had higher temperatures prior to virus challenge than those who remained free from illness. Similarly, those who later had colds were worse than other volunteers on certain performance tests given in the pre-challenge period. The results also showed that task-related motivation was related to subsequent infection. Personality scores were poor predictors of infection and illness, the only exception being introversion, which, in one study, was related to the likelihood of developing a sub-clinical infection.
