علم النفس الاجتماعي
Sociological social psychology focuses on micro-scale social actions. This area may be described as adhering to "sociological miniaturism", examining whole societies through the study of individual thoughts and emotions as well as behaviour of small groups. One special concern to psychological sociologists is how to explain a variety of demographic, social, and cultural facts in terms of human social interaction. Some of the major topics in this field are social inequality, group dynamics, prejudice, aggression, social perception, group behaviour, social change, non-verbal behaviour, socialization, conformity, leadership, and social identity. Social psychology may be taught with psychological emphasis. In sociology, researchers in this field are the most prominent users of the experimental method (however, unlike their psychological counterparts, they also frequently employ other methodologies). Social psychology looks at social influences, as well as social perception and social interaction.
