反馈干预的内部机制研究

基于龙君伟的反馈干预作用的内部机制模型,本实验研究发现反馈效价、反馈提供方式及其交互作用对自我效能感、应对策略、内部目标三种内部调节变量具有主效应;三种内部调节变量之问存在显著的正相关,并对绩效具有显著积极效应。在实际的应用中,反馈干预如能使个体采取趋向型的应对策略、增强自我效能感、提高内部目标设置水平,就能有效地提高个体的绩效水平。     

反馈干预对绩效的影响研究

反馈干预是由外部动因提供的关于个体任务操作或过去行为的信息活动,它有反馈对象、反馈效价和反馈提供方式三个维度。研究结果表明反馈效价、反馈提供方式对绩效的影响具有主效应,且两者的之间交互作用对绩效也存在主效应。积极反馈效价、信息型提供方式有助于提高个体的绩效水平。

动机的结构与效应：基于动机连续体的视角

动机是影响学生学业成绩重要的非认知因素。通常认为动机对学习是有利的,但研究发现并非所有动机都是有益的,这提醒研究人员有必要区分出各种不同的动机类型。现有研究一致表明内部动机对学业成就具有积极且长期稳定的效应,而外部动机的效应尚存在争议。具体而言,有研究者认为外部动机对学业成就是有害的,但部分研究发现外部动机在某些特定情况下能够发挥着不可或缺的积极作用。 针对上述存在的争议,本研究梳理了“动机连续体”这一概念,从两个方面的研究来进行阐释。首先,从大理论的角度整合了动机的相关理论,以自我决定理论的动机连续体为基础,引出相关理论,如兴趣理论、目标理论、期望价值理论、自我价值理论、强化理论、社会认知理论等。这些理论可以解释动机连续体中一种或几种类型的动机。 其次,从动机的结构及其如何影响结果变量这一角度对上述理论及其应用进行总结,主要存在四个观点。传统的争论集中在单维结构和多维结构之间。单维结构认为内部动机和外部动机是相互对立的,即内部动机会促进绩效,而外部动机会降低绩效。多维结构认为内部动机和外部动机能够相互累加,都能促进绩效。近年来,研究人员提出了更复杂的结构来整合上述观点。譬如半辐射结构使用全局因子来表示动机的整体水平,同时允许特定因子表示具体动机类型。这种半辐射结构借用了双因子模型,提取了一个“自我决定因子”,同时允许每种特定动机类型具有自身独特的影响。此外,乘积模型表明这两种动机之间存在交互作用,即外部动机的对结果的影响会因个体内部动机水平的变化而变化,反之亦然。 综上所述,本研究总结了关于动机连续体的不同理论之间的优缺点,回顾了动机结构的不同假设及其应用。在不同学科中对动机的测量方式、动机对不同结果变量的不同影响以及动机的跨文化研究等问题仍然是目前研究的热点。对动机结构和效应的深入探讨可以更好地帮助研究人员将不同的理论应用于适当的情境中。     

反馈干预对学习判断的影响

将反馈干预作为外部线索引入元记忆研究,采用重复学习任务,在第一轮次学习-测验之后插入反馈干预,用两个实验分别考查任务反馈和能力反馈两种形式下的反馈效价对第二轮次即时学习判断的影响.结果表明：①在学习过程中,学习者会进行自我监测;②在任务反馈形式下,反馈信息与自我监测信息冲突,导致反馈干预对元认知监测和认知过程没有影响;③在能力反馈形式下,反馈信息与自我监测信息的冲突消失,结果消极反馈影响了元认知监测.由此得出结论：只有在不与自我监测信息冲突的情况下,反馈干预才对学习判断产生影响.此外,在有反馈干预的情况下,两个实验中都出现了显著的练习伴随低估效应.     

论企业的内部与外部治理结构的统一

本文通过对国外有关企业治理结构的大量经典性文献的回顾和综述,提出了企业治理结构要达到内部治理与外部治理相统一、共同实现企业目标的思想.企业的性质决定了企业的目标是实现内部资源优化配置和外部关系整合,从而达到绩效最优.企业治理结构研究的是企业资本供给者得到投资回报的方法问题,企业治理结构是指所有者对一个经营管理和绩效进行监督和控制的一整套制度安排.企业治理的合理逻辑应该是市场与环境整治--内部控制与激励--企业治理绩效.

追加反馈对运动技能学习影响的国外研究进展

Adams认为：没有反馈就没有学习。通常,指导者能直接控制的反馈是外部反馈,也称为追加反馈(Augmented Feedback)。传统观点认为：追加反馈越频繁、越及时．学习效果就越好。但近年来。国外出现了许多与此相悖的研究成果。所以．对国外关于追加反馈研究进展的分析．有助于促进国内研究者对运动技能学习基本理论的研究。     

奖励的价值导向对绩效反馈效果的影响

本研究探讨了奖励形式启动的价值框架效应在调节绩效反馈对绩效提升与行为塑造的效果中发挥的作用。对231名大学生的问卷调查结果表明,采用金钱奖励时,接受个人绩效反馈的个体效能感更高,也有更好的绩效和合作行为表现;采用荣誉奖励时,集体绩效反馈的效果更好。即奖励形式与绩效反馈的匹配会提高组织成员绩效,增加其合作行为。基于该结果,建议管理者关注奖励体系中的价值信息与组织的管理方式相匹配,以推进组织的可持续发展。     

An internal focus of attention is optimal when congruent with afferent proprioceptive task information

Whilst benefits of an external focus are shown to govern several characteristics of skill execution, specificity theory indicates that sources of afferent information most useful to performance execution are typically prioritised during processing.ObjectivesWe investigated whether an internal focus facilitates performance when pertinent afferent information is proprioceptive in nature and congruent with attentional focus. We also considered whether the mechanisms behind attentional focus differences are attributable to planning processes or online motor control.DesignExperiments 1 and 2 adopted a randomised design, whilst experiment 3 used a repeated measures approach.MethodIn Experiment 1 we investigated movement variability as a measure of planning and error correction under external and internal focus conditions in an aiming task. Experiment 2 removed visual information to increase pertinence of proprioceptive feedback for movement execution and Experiment 3 adopted a leg-extension task, where proprioceptive salience was enhanced using an ankle weight. We hypothesised that this would increase congruency between internal focus instructions and movement production.ResultsExperiments 1 and 2 revealed reduced amplitude errors under an internal focus whilst Experiment 3 showed similar findings with the addition of lower EMG activity when adopting an internal focus. Movement variability findings were indicative of enhanced planning.ConclusionsWhen pertinence of proprioceptive information was amplified, benefits of an internal focus were more pronounced and performance was higher. Participants were better able to focus on movement characteristics to process proprioceptive feedback: something not afforded under an external focus. This raises doubts regarding the rigidity of the constrained action hypothesis.     

Knowledge and use of memory strategies in amnestic mild cognitive impairment

Despite the inclusion of memory strategy training in many interventions for amnestic mild cognitive impairment (aMCI), little research has directly examined knowledge and use of memory strategies in aMCI and their relationship to memory performance in order to guide the development of targeted interventions. The present study aimed to compare strategy knowledge and use between an aMCI and a healthy older adult (HOA) sample, and to determine the contribution of strategy knowledge and use to memory performance in each of these groups. The sample comprised 37 aMCI and 52 HOA participants aged over 60 years. All participants completed questionnaires to assess strategy knowledge and self-reported use of internal and external strategies in everyday life. In addition, strategy use was observed on the measures of retrospective and prospective memory performance (the CVLT-II and the CAMPROMPT). The aMCI group demonstrated decreased strategy knowledge and observed use of internal strategies, although equivalent observed use of external strategies compared with the HOA group. Furthermore, they reported equivalent use of both internal and external strategies. Observed use of strategies was significantly associated with retrospective memory performance for both groups and prospective memory performance for the aMCI group, supporting the inclusion of strategy training in interventions.     

Locus of control and effects of failure on perfomance and perceived competence

Reactions to related performance feedback of 117 internal and external eighth-grade children were investigated under conditions which made denial of personal responsibility for outcomes difficult. Both internals and externals were equally pleased by success feedback and displeased by failure and their competence judgement was influenced by the feedback received. However, internals exhibited more effective coping with failure than did externals. They improved their performance following failure feedback relatively more than after success and no external feedback conditions, and their percieved competance did not decrease in comparison with externals.     

Coaching cues in amateur boxing: An analysis of ringside feedback provided between rounds of competition

Feedback is commonly employed to enhance motor learning and performance. While numerous studies have investigated the causal effects of feedback on motor learning, an analysis of real-time feedback provided during training and competitive sporting environments is lacking. Therefore, the feedback provided by 12 boxing coaches to athletes between rounds of the 2015 Australian Boxing Championships was recorded and transcribed. The feedback statements were then analyzed according to three feedback variables that have been shown to be critical for optimizing performance: Attentional focus (external, internal, neutral), autonomy support (autonomy-supportive, controlling, neutral), and feedback valence (positive, negative, neutral). Collectively, 445 feedback statements provided during 25 bouts, of which 14 were won and 11 were lost, were analyzed for each of the three categories. Coaches provided on average 8 feedback statements per round. Excluding neutral statements, coaches delivered more internal (15%) compared with external focus feedback (6%), more controlling (53%) compared with autonomy-supportive feedback (6%), and more positive (29%) relative to negative feedback (12%). Furthermore, during winning bouts coaches delivered less internal (12% vs. 19%), less controlling (48% vs. 58%), and more positive (36% vs. 18%) feedback, when compared with losing bouts. These results demonstrate for the first time the type and frequency of feedback delivered during amateur boxing bouts. While these findings may or may not reflect causal relationships, it is interesting that feedback that has been found to enhance motor performance was more often used during winning rather than losing bouts.     

Task feedback effects on conflict monitoring and executive control: relationship to subclinical measures of depression

Emerging evidence suggests that depression is associated with executive dysfunction, particularly after committing errors or receiving negative performance feedback. To test this hypothesis, 57 participants performed two executive tasks known to elicit errors (the Simon and Stroop Tasks) during positive or negative performance feedback. Participants with elevated depressive symptoms (Beck Depression Inventory scores >or= 13) were characterized by impaired posterror and postconflict performance adjustments, especially during emotionally negative task-related feedback. Additionally, for both tasks, depressive symptoms were inversely related to postconflict reaction time adjustments following negative, but not positive, feedback. These findings suggest that subclinical depression is associated with impairments in behavioral adjustments after internal (perceived failure) and external feedback about deficient task performance.     

Feedback seeking as a means of self-assessment and affect optimization

Previous research on feedback choice found considerable inter- and intraindividual differences. It is proposed here that these differences can in part be explained by personality factors (i.e., anxiety and competence) that influence the informational value of external feedback and the congruence between internally generated and externally provided feedback. Feedback seeking was analyzed in two studies in which subjects, working on long series of tasks, had the opportunity to request various forms of achievement feedback. Since complex tasks were used, feedback only marginally affected learning. Anxiety, competence, and expenses for obtaining feedback served as independent variables. Results showed that subjects intending to optimize their affective state (i.e., reduce anxiety) have a strong preference for external feedback, and use such feedback mainly to neutralize aversive internal feedback. In contrast, persons who tried to use feedback as a means to enhance or assess performance suffered from an increased affective load.     

How do the dynamics of shame influence smartphone addiction of Korean Christian adolescents? A study based on external and internal shame

Individuals with negative feeling such as shame might be vulnerable to smartphone addiction. The present study aimed to explore the relationship of smartphone addiction with external shame and internal shame in a sample of Christian adolescents in Korea. The correlational and causal relationships between Korean Christian adolescents’ smartphone addiction and external shame-including others and God-and internal shame were examined. Through a correlational analysis, the study found that external shame-others, external shame-God, internal shame, and smartphone addiction were all highly correlated with each other. During causal and mediation analyses, it was found that internal shame mediated external shame-others and smartphone addiction and also mediated external shame-God and smartphone addiction. In addition, the study offers a discussion of its finding and suggestions for clinical interventions.     

Effects of immediate performance feedback on implementation of behavior support plans

Research has focused on increasing the treatment integrity of school-based interventions by utilizing performance feedback. The purpose of this study was to extend this literature by increasing special education teachers' treatment integrity for implementing antecedent and consequence procedures in an ongoing behavior support plan. A multiple baseline across teacher-student dyads (for two classrooms) design was used to evaluate the effects of performance feedback on the percentage of antecedent and consequence components implemented correctly during 1-hr observation sessions. Performance feedback was provided every other week for 8 to 22 weeks after a stable or decreasing trend in the percentage of antecedent or consequence components implemented correctly. Results suggested that performance feedback increased the treatment integrity of antecedent components for 4 of 5 teachers and consequence components for all 5 teachers. These results were maintained following feedback for all teachers across antecedent and consequence components. Teachers rated performance feedback favorably with respect to the purpose, procedures, and outcome, as indicated by a social validity rating measure.     

Leader Attributions for Subordinate Performance: Consequences for Subsequent Leader Interactive Behaviors and Ratings1

An important application of attribution theory deals with leader explanations for subordinate performance and their effects on future leader–member interactions and performance. In the present study, subjects worked on a 2-trial task in which there was a leader and 2 members. Leaders received performance feedback and an attributional explanation for subordinate performance after Trial 1, and subsequent Trial 2 behavior was videotaped. Results showed that attributions significantly affected the amount of time spent by the leader talking to the group during the second trial, as well as the number of negative leader comments. Level of performance was a significant determinant of subordinate ratings and reward/punishment recommendations. Attributions differentially affected the punishment advocated by leaders, with failure due to internal causes more likely to be punished than failure due to external causes. Implications for an attributional theory of leadership are discussed.
