Behavioral Theory of leadership is a big leap from Trait Theory, as it was developed scientifically by conducting behaviour focused studies. The theory emphasizes that leadership capability can be learned, rather than being inherent. This theory is based on the principle that a leader's behaviors can be conditioned in a manner that one can have a specific response to specific stimuli.
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.
