Question: What Is Social Psychology?

Answer:
According to psychologist Gordon Allport, social psychology is a discipline that uses scientific methods "to understand and explain how the thought, feeling and behavior of individuals are influenced by the actual, imagined or implied presence of other human beings" (1985).
Social psychology looks at a wide range of social topics, including group behavior, social perception, leadership, nonverbal behavior, conformity, aggression and prejudice. It is important to note that social psychology is not just about looking at social influences. Social perception and social interaction are also vital to understanding social behavior.

Brief History of Social Psychology

While Plato referred to the idea of the "crowd mind" and concepts such as social loafing and social facilitation were introduced in the late-1800s, it wasn't until after World War II that research on social psychology would begin in earnest. The horrors of the Holocaust led researchers to study the effects of social influence, conformity, and obedience.
The U.S. government also became interested in applying social psychological concepts to influencing citizens. Social psychology has continued to grow throughout the twentieth century, inspiring research that has contributed to our understanding of social experience and behavior.
