Effects of guided notes versus completed notes during lectures on college students' quiz performance

We compared the effects of guided lecture notes versus completed lecture notes on pre- to postlecture improvements in quiz performance across two sections of a college course. The results of a counterbalanced multielement design did not reveal consistent differences between the two note formats on students' mean quiz scores. However, fewer errors occurred on complex (analysis-level) quiz questions in the guided notes condition than in the completed notes condition.     

Episodic chasing in pathological gamblers using the Iowa gambling task

"Chasing ones losses" is a key symptom among pathological gamblers (PGs). This study focuses on quantitative differences in episodic chasing (i.e., sequences of disadvantageous decisions within a single gambling session) between PGs and non-pathological gamblers (NPGs). We compared 61 PGs and 39 NPGs on the Iowa Gambling Task (IGT) and the Zuckerman Sensation Seeking Scale (SSS). The PGs showed significantly more chasing and had significantly poorer decision-making strategies than NPGs, particularly among males (F = 4.52, p < 0.05). Random players were significantly less sensation seeking than advantageous and disadvantageous (i.e., chasing) players, but there was no interaction with group or gender. The results suggest that quantifiable within-session gambling behavior holds important implications for detecting underlying vulnerabilities to gambling pathology.     

Effects of team and organizational commitment – A longitudinal study

Retention management, i.e., keeping qualified employees, is a top priority for contemporary organizations. Commitment, and especially team commitment, can be the key to mastering this challenge. There is a lack of longitudinal research concerning the development and the direction of the effects of team commitment over time. In a longitudinal field-study design with three points of measurement, a total of 360 employees in 52 semi-autonomous industrial teams were surveyed over a period of three years. On the one hand, organizational commitment showed stronger effects on organization-related criteria (job satisfaction and intention to leave). These effects were consistent over the three points of measurement. Team commitment, on the other hand, affected team-related criteria (team performance and altruism). Longitudinal analyses confirmed the effects of organizational commitment on job satisfaction and intention to leave, and of team commitment on team performance and altruism. Moreover, these effects increased over time. Theoretical and practical implications of these findings are discussed.     

A behavioral intervention for teaching tackling skills to high school football athletes

We evaluated an intervention that combined task analysis and differential reinforcement for teaching tackling skills to 2 high school football athletes. As a result of intervention, both players tackled more proficiently in practice drills and maintained proficient tackling during games.     

生涯适应力的作用：个体与组织层的跨层面分析*

生涯适应力(career adaptability)是生涯建构理论提出的自我职业生涯管理的核心概念,但国外理论和实践一直认为生涯适应力是一把双刃剑(生涯适应力高的员工工作绩效高,但其离职意向也高),本研究将对此进行检验;同时,生涯适应力作为个体职业生涯开发的核心变量,它在组织职业生涯管理跨层面作用中的价值也未曾研究。通过员工在两个时间点自评和管理者他评问卷,获得54家单位的485份有效调查问卷。结构方程模型分析的结果表明,生涯适应力不仅与工作绩效有显著正相关,而且也与离职意向有显著负相关。层次回归分析结果表明,工龄是生涯适应力与离职意向、工作绩效关系的调节变量;也就是说,工龄短员工的生涯适应力与工作绩效呈显著正相关,与离职意向呈显著负相关,但工龄长员工的生涯适应力与二者的关系都不显著。基于跨层面研究设计,多层线性模型(HLM)分析的结果表明,生涯适应力是组织职业生涯管理与个体工作绩效之间的完全中介变量,但在组织职业生涯管理与离职意向之间的中介作用不显著。这不但回答了生涯适应力对组织价值的管理困境问题,也解决了组织职业生涯管理与个体工作绩效的连接纽带问题。     

登机牌信息要素及其布局研究

随着民航行业的快速发展,飞机登机牌的使用率越来越高,而不同航空公司所采用的登机牌在信息内容和布局设计等方面均缺乏相关的设计规范,因此有必要从可用性角度对登机牌进行系统的研究.首先,采用KANO问卷法对登机牌上的文字信息要素进行研究,并基于研究结果设计出新登机牌;然后,从搜索绩效和主观偏好两个方面对新旧登机牌进行比较评价研究.结果显示：①登机牌上必须呈现的信息主要包括登机时间、登机口、航班号、座位号、姓名、日期和目的地七项必要信息,以及可提高旅客使用体验的预计飞行时间信息,但登机牌上不能呈现旅客身份证号码等个人隐私信息;②基于信息要素研究结果重新布局设计的新登机牌在搜索绩效和主观偏好方面均显著优于现有登机牌.本研究结果可为将来的登机牌设计提供科学依据.     

How to achieve synergy in group decision making: Lessons to be learned from the hidden profile paradigm

Based on over 25 years of research on hidden profiles and information sharing in groups, and particularly our own work in this area, we outline a general model of how groups can achieve better decisions in a hidden profile situation than their individual members would have been capable of (i.e., synergy). At its core the model defines intensity and bias as the two key parameters that have to be optimised with regard to both the discussion of information and the processing of information in order to ensure synergy in group decision making. We review the empirical literature on information sharing and group decision making in the hidden profile paradigm (with a particular focus on our own studies) to illustrate how group decision quality can be enhanced by increasing intensity and decreasing bias in the discussion and processing of information. Finally we also outline why we think that the lessons learned from research using the hidden profile paradigm can be generalised to group decision-making research in general, and how these lessons can stimulate studies in other fields of group decision-making and group performance research.     

The Impact of Leadership Style on Moral Identity and Subsequent In-Role Performance: A Moderated Mediation Analysis

This study investigated the impact of supervisors’ servant leadership (i.e., leadership that starts with a leader who wants to serve) on supervisees’ moral identity and subsequent in-role performance. Data from 226 supervisor–supervisee dyads were collected from several domestic and multinational companies operating in the Kingdom of Saudi Arabia. Confirmatory factor analysis was conducted to confirm the factorial validity of the measures that were employed in this study. The hypothesized moderated mediation model was tested using hierarchical multiple regression analysis. Based on social learning theory, the results showed that supervisees’ moral identity served as the psychological mediating mechanism through which supervisors’ servant leadership led to supervisees’ increased in-role performance. Furthermore, the results also supported supervisees’ avoidance orientation as the dispositional boundary condition of this mediating effect. This study contributes to both the servant leadership and moral identity literatures by addressing questions with useful theoretical and managerial implications.     

Training in Timing Improves Accuracy in Golf

In this experiment, the authors investigated the influence of training in timing on performance accuracy in golf. During pre- and posttesting, 40 participants hit golf balls with 4 different clubs in a golf course simulator. The dependent measure was the distance in feet that the ball ended from the target. Between the pre- and posttest, participants in the experimental condition received 10 hr of timing training with an instrument that was designed to train participants to tap their hands and feet in synchrony with target sounds. The participants in the control condition read literature about how to improve their golf swing. The results indicated that the participants in the experimental condition significantly improved their accuracy relative to the participants in the control condition, who did not show any improvement. We concluded that training in timing leads to improvement in accuracy, and that our results have implications for training in golf as well as other complex motor activities.
