Leadership Research and Theory: A Functional Integration

This historical overview of leadership theory and research with an eye for commonalities provides an opportunity for integration. Early unproductive research focused on personality traits and behaviors. A recognition of the more complex nature of the phenomenon resulted in the development of contingency theories that examined leader characteristics and behavior in the context of situational parameters. The 1970s brought an awareness that perceptions of leaders by followers and others, and perceptions of followers by leaders, were influenced by cognitive biases arising from prior expectations and information-processing schema. Ironically, attention was belatedly drawn to the study of female leaders, who were often the victim of cognitive biases and negative assumptions. Recent research has reflected on the role of cultural differences in leadership processes and has been drawn again into the search for outstanding leaders with universally effective characteristics. The article concludes with an integration of current knowledge in leadership effectiveness.
