Social psychology explores how we perceive individuals, form and alter our attitudes, and how attraction occurs between people. It examines how others influence our behaviors and the role of attributions—both internal and external—in shaping our understanding of actions. Important concepts include biases in attribution, persuasion methods (central vs. peripheral), and cognitive dissonance, which creates discomfort when our beliefs and behaviors conflict. Factors affecting attraction, social influence, conformity, and the bystander effect highlight the power of situational dynamics in human interactions.
