领导者信任理论述评

该文整合了过去三十年来,西方关于领导者信任的理论研究之后发现,领导者所表现出的可信行为,在员工归因的作用下,可以对组织绩效、员工工作态度、目的等产生极其重要的影响。作者在对以往研究作出总结的基础上,对西方研究存在的问题以及未来研究的发展方向提出了建议。     

Effects of Performance Context on Processing Speed and Performance Ratings

The present study demonstrated that the presence of evaluatively polarized context performances not only produces contrast and halo effects on judgments of a target performance, but also causes judgments to be made much faster. Processing speed and positive halo were highly correlated, supporting the notion that halo in performance ratings results from raters' recall and use of a single, general impression. Furthermore, regression analyses demonstrated that processing speed mediates the relationship between context and halo. The relationship between these findings, halo, processing speed, and general impressions, as well as implications for performance appraisals, are discussed.

Fluent Reading as the Improvement of Stimulus Control: Additive Effects of Performance-Based Interventions to Repeated Reading on Students' Reading and Error Rates

The impact of adding performance-based interventions to a skill-based intervention on oral reading fluency was examined with 3 elementary students identified as having difficulty with reading. Two performance-based interventions were combined with the skill-based intervention Repeated Reading (RR) to create the three instructional packages investigated. The packages included Repeated Readings (RR), Repeated Readings with Performance Feedback (RR/FB), and Repeated Readings with Performance Feedback and Contingent Reward (RR/FB/REW). Results suggested that Repeated Reading (RR) alone led to the greatest increase in reading fluency for participants with the highest reading rates and lowest error rates at baseline. In contrast, the participant who exhibited the lowest reading rate and highest error rate benefited the most when Repeated Readings was offered in conjunction with Performance Feedback (RR/FB) or Performance Feedback plus Contingent Reward (RR/FB/RW). Implications for blending skill- and performance-based interventions to develop stimulus control over fluent reading and future research directions are discussed.     

Predicting athletic performance from cardiovascular indexes of challenge and threat

This study examined the relationship between pre-performance motivational states (challenge vs. threat) and subsequent performance in athletic competition. Prior to the season, college baseball and softball players imagined and gave a speech about a specific baseball/softball playing situation while cardiovascular indexes of challenge and threat were recorded. These physiological challenge/threat indexes significantly predicted athletic performance during the subsequent season, such that players who experienced challenge in the laboratory performed better relative to those who experienced threat. The implications for personnel selection and the biopsychosocial model of challenge and threat are discussed.     

The relationship between personality, approach to learning and academic performance

This study considers the relationship between students' approaches to learning, as measured by a short-form of Entwistle and Tait's (1995) Revised Approaches to Studying Inventory (RASI), the Big Five personality factors, as measured by Cattell's 16PFi, and the background variables of age, gender and prior educational achievement and academic performance. Subjects were 146 social science undergraduate students at a university in Scotland. Structural equation modelling identifies the Big Five personality factor scores account for between 22.7% and 43.6% of the variance across scores on the three approach to learning dimensions. Four of the Big Five personality factors and the three approach to learning dimensions were found to be poor predictors of academic performance. A linear regression analysis with academic performance as the dependent variable and age, prior educational attainment and conscientiousness as independent variables, accounted for 24.1% of the variance in performance. Our investigation suggests approach to learning is a subset of personality. However, we conclude it makes sense to measure these two groups of variables separately in educational settings.     

The STEPPS Group Treatment Program for Outpatients with Borderline Personality Disorder

The authors describe a new cognitive-behavioral systems-based group treatment for outpatients diagnosed with borderline personality disorder (BPD). The program is identified by the acronym STEPPS, which stands for Systems Training for Emotional Predictability and Problem Solving. The STEPPS program was developed to address the cognitive distortions and behavioral dyscontrol typical of clients with BPD, and combines this with skills training and a systems component. The latter involves clients with BPD and those in their system including family members, significant others, and health care professionals. The program is fully manualized, and involves 20 two-hour weekly group meetings; specific goals (or lessons) are identified for each session. Preliminary data from the US and the Netherlands have shown that the group achieves high levels of acceptance from clients and therapists and that the model may be effective in helping to relieve the symptoms associated with BPD. Work is now underway to confirm the effectiveness of the model through a randomized controlled trial.     

A widely applicable extension of the random effects two-way layout: Its definition and statistical analysis based on group invariance

A type of data layout that may be considered as an extension of the two-way random effects analysis of variance is characterized and modeled based on group invariance. The data layout seems to be suitable for several scenarios in psychometrics, including the one in which multiple measurements are taken on each of a set of variables, and the measurements can be divided into exchangeable subsets. The algebraic structure of the model is studied, which leads to results that are applicable to such problems as estimating correlation matrix corrected for attenuation and testing symmetry hypotheses.The author would like to thank NIH for support through grants M01 RR00044 and P01 DE13539, and NSF and ASA Survey Section for a travel grant which allowed him to present this paper as an invited young researcher at the Conference in Celebration of Wayne A.

Exploring the rabbit hole of possibilities by myself or with my group: The benefits and liabilities of activating counterfactual mind‐sets for information sharing and group coordination

The current experiment explored the effect of activating a counterfactual mind‐set on the discussion of unique information and group judgment accuracy. Evidence suggests that a counterfactual mind‐set is characterized by a focused, analytic mental state and, when activated at the group level, improves group judgment accuracy in the murder mystery paradigm (a hidden profile task). We hypothesized that the beneficial effect of the counterfactual mind‐set would only help group problem‐solving tasks if the mind‐set had been activated at the group level, allowing the analytical mind‐set to play out in an atmosphere of synergistic coordination. In contrast, if this highly focused mental state is activated at the individual level, it could impair group judgment quality because inwardly focused analytical individuals may fail to coordinate their behavior with other group members. Consistent with our hypothesis, activating a counterfactual mind‐set at the individual level had a debilitating effect on the group judgment task, whereas activating a counterfactual mind‐set at the group level had a facilitative effect, increasing information sharing, synergistic coordination and judgment accuracy.
