Chapter one: social psychology is the scientific study of how individuals think, feel, and behave in a social context, sociology, for instance, typically classifies people in terms of their nationality, race, socioeconomic class, and other group factors. In contrast, social psychology typically focuses on the psychology of the individual. Even when social psychologists study groups of people, they usually emphasize the behaviour of the individual in the group context: clinical psychologists seek to understand and treat people with psychological difficulties or disorders. This scientific approach to studying the effects of the social context on individuals" behaviour can be seen as marking the birth of modern-day social psychology: a case can also be made for the french agricultural engineer max ringelmann. Ringelmann"s research was conducted in the 1880s but wasn"t published until: in an interesting coincidence, ringelmann also studied the effects of the presence of others on the performance of individuals.
