Examining the Effects of Feedback Accuracy and Timing on Skill Acquisition

ABSTRACT

Feedback involves providing information about past performance and indicating how to improve future performance. Although the literature contains numerous examples of feedback as an effective method for improving performance across a range of organizational settings, much remains unknown about the specifics of how feedback acts to change behavior. This study evaluated the combined effects of feedback accuracy (100%, 80%, 20%) and timing (feedback following each trial or after a block of 25 trials) on skill acquisition in undergraduate students when presented with a computerized match-to-sample task that required participants to learn the names of shapes. Results reveal that feedback accuracy had a significantly greater effect on performance than the timing of the feedback.

Narcissistic leadership

Narcissism—a personality trait encompassing grandiosity, arrogance, self-absorption, entitlement, fragile self-esteem, and hostility—is an attribute of many powerful leaders. Narcissistic leaders have grandiose belief systems and leadership styles, and are generally motivated by their needs for power and admiration rather than empathetic concern for the constituents and institutions they lead. However, narcissists also possess the charisma and grand vision that are vital to effective leadership. We review and critically assess the theoretical and research literature on narcissistic leaders in order to understand the potential positive and negative consequences of their leadership, the trajectories of their leadership, and the relationship of narcissism to established models of leadership. We conclude that the study of narcissistic leaders is inherently limited in scope, and propose a new definition of narcissistic leadership in order to reframe the discussion and better incorporate the topic of narcissism into the field of leadership studies.     

我国企业领导价值观传递模式研究

此研究识别了三种企业领导人灌输价值观的典型模式--强制式、制度驱动式和激励式,并检验了这三种灌输方式对下属认同的影响作用.结果表明,应用强制的方法灌输个人价值观,会导致下属"内化"程度的显著降低;制度驱动式和激励式的价值观灌输方式能导致下属的"认可"和"内化".另外,本研究也比较了企业创始人与非创始人型领导在价值观传递过程中的差别.本文讨论了所发现的有意义的结论,也探讨了相应的研究局限性并提出了对未来研究的建议.     

“Trees Die From the Top”: International Perspectives on NGO Leadership Development

This paper examines the role of leadership development in NGO capacity building and assesses some of the challenges of developing a new generation of NGO leaders. The paper draws on the analysis of new and existing research into the dimensions of NGO leadership highlighting the importance of both individual attributes and contextual relevance. Effective NGO leaders are able to balance a range of competing pressures from different stakeholders in ways that do not compromise their individual identity and values. Leadership development programmes therefore need to focus on both the values and identity of individual leaders while also assisting leaders understand and proactively respond to their rapidly changing external environment. We conclude that there is an urgent need to build the capacity of NGOs to develop their leadership capability. Unless systems and processes to support this work are put in place then the apocryphal warning trees die from the top will have more than a ring of truth in it.
