Social psychology is a branch of psychology that studies individuals in the social context.
In other words, it is the study of how and why people think, feel, and do the things they do depending upon the situation they are in. Social psychology is related to sociology in this regard, but instead of focusing on group factors such as race and socioeconomic class, it focuses on the individual. Also, it relies on the scientific research to generate the theories of social behavior. In studying how people act in certain situations, we can better understand how stereotypes are formed, why racism and sexism exist, how a person can seem like an entirely different person in different situations, and even how people fall in love. There are many important factors in how one perceives oneself.
