The four theory of leadership was formulated after studying hundreds of leaders and the model includes four basic dimensions of effective leadership - support; interaction; facilitation; goal emphasis, and work facilitation. This model was tested as a predictor of an organization's effectiveness.
Trait theories of leadership identify the specific personality traits that distinguish leaders from non-leaders. The trait model of leadership is based on the traits or characteristics of leaders that make them successful in their leading role. These theories use heritable attributes to predict leadership effectiveness.
The Fiedler Model of leadership is a contingency theory and states that a leader's effectiveness is based on the situation. There is no one best style of leadership and the effectiveness of a leader in an organization depends on matching the leader to the situation. Leaders should determine the natural leadership style and assess the situation to flex the style.
The group and exchange theories of leadership are derived from social psychology. These have their roots in the exchange theory. Leaders from different kinds of relationships with various groups of subordinates. Group theories describe how leaders need to maintain their position in group dynamics.
Social learning theory is a theory of learning process that states that most human behavior is learned observationally through modeling. Behavior change can occur in response to leader modeling and learning occurs through the observation of rewards and punishments. The focus of this approach has been teaching leadership across formal and informal settings.
Have you ever resonated that there seem to be as many different ways to lead people as there have been great leaders? When we recall the success of Mahatma Gandhi, Nelson Mandela, Abraham Lincoln, Napoleon Bonaparte to Steve Jobs and Jack Welch, we also notice that they all used different approaches that were suitable to their specific situations and circumstances. Over the last century, researchers and psychologists have developed simple ways to describe the “Styles of leadership” and in this section, we will explore these commonly known leadership styles.
Jung first introduced his personality theory and explained that all humans have a natural impulse to relate meaningfully to the world through productive work and people through significant relationships. He used four psychological functions - thinking and feeling (rational functions) and sensation and intuition (irrational functions). He also used introversion and extraversion and its impact on appropriate leader behaviors.
Team leadership theory is a recent leadership theory that does not discriminate between the leader and the other team members. The approach considers contributions from each team member to be critical for organizational success. This approach focused on the overall team effectiveness and team problems are diagnosed and action is taken to remediate weakness. This approach provides for taking corrective action when the leader deems necessary.
McGregor's Theory X and Theory Y
McGregor created Theory X and Theory Y of human work motivation and explained two styles of management known as authoritarian (Theory X) and participative (Theory Y). Theory X management assumes most people will attempt to avoid work whereas Theory Y managers trust their people to take ownership of their work.
Early studies on leadership were done at Ohio State University using the Leader Behavior Description Questionnaire to identify the leader's observable behaviors. Ohio State study on leadership found two behavioral characteristics of leadership - people-oriented (consideration) and task-oriented (initiating structure) leadership style.
In the field of communication studies, there are numerous models. No one model is suitable for all purposes and all levels of analysis. Some common models are known as Lasswell Model, George Gerbner Model, David Berlo Model, Shanon and Weaver Model, Osgoods Model, and Schramm Model. All these describe the four components of the communication process, namely, the source (communicator), the message, the channel, the receiver (audience).
