Research into the origins, dynamics, and changes of attitudes and beliefs has been carried out by laboratory experiments (studying relatively minor effects), by social surveys and other statistical field studies, by psychometric studies, and occasionally by field experiments. The origins of these socially important predispositions have been sought in the study of parental attitudes, group norms, social influence and propaganda, and in various aspects of personality. The influence of personality has been studied by correlating measured attitudes with individual personality traits and by clinical studies of cognitive and motivational processes; so-called authoritarian behaviour, for example, has been found to be deeply embedded in the personality of the individual. Early research based on statistical analyses of social attitudes revealed correlations with such factors as radicalism–conservatism. Later research on consistency provided extensive laboratory evidence of consistency but little evidence of it in actual political behaviour (e.g., in attitudes on different political issues).

Research on attitude change has studied the effects of the mass media, the optimum design of persuasive messages, the effects of motivational arousal, and the role of opinion leaders (e.g., teachers and ministers). Research has been carried out into the origins, functioning, and change of particular attitudes (e.g., racial, international, political, and religious), each of which is affected by special factors. Attitudes toward racial minority groups, for example, are affected by social conditions, such as the local housing, employment, and the political situation; political attitudes are affected by social class and age; and religious attitudes and beliefs strongly reflect such factors as inner personality conflict.

Various specialties in social psychology

Many social psychologists are concerned with such aspects of public opinion (social survey) research as the design of standardized interviews and questionnaires. Forms of questions have been devised to compensate for errors that arise from the efforts to respond in a socially approved manner; some are designed to detect lying. Mass communications have been devised on the basis of research into persuasion. Use is also still made of Freudian symbolism and theory.

Research into the causes of mental disorders has shown the importance of social factors in the family and elsewhere. Mental patients often show deficiencies in social performance that may be the cause of other symptoms. Many social psychologists hold that social factors may also apply to such disorders as schizophrenia, which also seem to have hereditary and chemical bases. There has been a corresponding growth in the use of various kinds of social therapy in psychiatry (e.g., group therapy, therapeutic communities, and social-skills training).

Considerable research has been devoted to industrial productivity, absenteeism, labour turnover, accidents, and job satisfaction. Factors that have been found to be important include the style of supervision and management, the size and composition of working groups, the technology and the work-flow systems, the span of control, and other features of the organizational structure. Research results point strongly toward the advantages of a less rigid hierarchical structure of authority, with more delegation of authority and consultation, training in supervisory skills, small and cooperative work teams, and interesting and varied work.

A major application of research in social interaction and group behaviour is in training in social skills, as in the T-groups, or sensitivity training, noted above. Role playing with video-tape playback and training in the imitation of other persons who serve as behavioral models are used in teaching people new skills. Actual training on the job has the advantage that there is no gap between the training and the work itself. All of these methods have been shown to be effective, depending on the job and the teacher. Social-skills training has been given successfully to industrial managers and supervisors, social workers and clergymen, interviewers, public speakers, mental patients, and juvenile delinquents.

A great deal of research has been done on factors underlying racial prejudice, but the understanding thus obtained has not had much effect upon the social problems involved. Similarly, the causes of delinquency and crime have been extensively studied, but it is not feasible to manipulate the factors influencing crime, such as genetic factors, methods of upbringing, and inequalities of opportunity. Social psychology has made some contribution to education; sociometry is quite widely practiced as a means of grouping children, and evidence is growing about the optimum styles of teacher behaviour.
