This document discusses social psychology and leadership. It defines leadership as the ability to motivate a group towards a common goal without coercion. Effective leadership requires traits like energy, communication skills, and initiative. There are three main leadership styles: autocratic, where the leader makes all decisions; democratic, where decisions involve others; and free-rein, where responsibilities are shared. Leadership theories examine traits, behaviors, situational factors, and adapting styles to follower maturity levels. Formal leadership comes from a managerial position, while informal leadership arises from influence without authority.
