Social Psychology



Social psychology is the study of how people think about, influence, and relate to one another. People tend to change their beliefs and behaviors in response to group pressure. Conforming to a group hinders people from sharing their opinions, which can inhibit diversity and informed decision-making. Social factors that increase the likelihood of forming relationships include proximity and repeated exposure, which make it easier for people to get to know each other. Prosocial behavior and antisocial behavior are respectively associated with helping behavior and aggression. Social groups can influence a person's identity, self-esteem, and prejudices. Attitudes can be influenced by external and internal factors, including cognitive dissonance and persuasion.
