The Leader-Member Exchange Theory (LMX), also called the Vertical Dyad Linkage Theory is a relationship-based approach that focuses on the two-way (dyadic) relationship to get the best from all team members. How leaders maintain their position in groups and develop an exchange with each of their subordinates. How leaders and members develop relationships that can contribute to growth or hinder development.
Reciprocal influence theory also known as reciprocal determinism is authored by Albert Bandura and states that an individual's behavior influences and is influenced by both the social world and personal characteristics. Three factors that influence behavior are the environment, the individual, and the behavior itself. Certain leader behaviors can cause subordinate behaviors and reciprocal influence on the leader by the group.
