What it studies

The Society for Personality and Social Psychology says personality and social psychologists explore forces within the person and within the situation to understand individual and social life. This guide lists personality psychology as a separate neighboring route, although the society pages treat the two together. Early experiments in the area asked whether another person's presence changes performance.

History and people

Experimental work on social influence appeared before the field had a modern identity. Féré described experiments in 1887, Binet and Henri studied social influence among children in 1894, and Norman Triplett published a study of cycling and competition in 1898. Wolfgang Stroebe argues that the common story of Triplett as the first experimenter is largely wrong. In 1924 Floyd Allport's textbook defined social psychology as the experimental study of social behavior. The Society for Personality and Social Psychology was founded in 1974.

People and documented roles

  • Norman Triplett. Author of an 1898 study of pacemaking and competition in cycling
    • Published an article analyzing cycling records and reporting laboratory experiments on the effect of another person's presence on performance. [3]
  • Floyd Allport. Author of a 1924 social psychology textbook
    • His textbook defined social psychology as the experimental study of social behavior, according to Stroebe's account. [4]

The sources opened name only these two contributors with documented roles, plus Féré, Binet and Henri as authors of earlier work. They do not document women, scholars outside Europe and North America, or other contributors, so none are listed.

Dated milestones

  • 1887Publication. Year.Charles Féré's book describing experiments on how others' presence could raise individual performance, as reported by Stroebe. [4]
  • 1894Research report. Year.Binet and Henri's study of social influence among children, as reported by Stroebe. [4]
  • 1898Publication. Year.Triplett's article on pacemaking and competition in the American Journal of Psychology. [3]

  • 1974Society or organization formed. Year.The Society for Personality and Social Psychology states it was founded. This is a society event, not the start of the field. [2]

Methods

Triplett combined analysis of official racing records with laboratory experiments on whether the presence of another contestant changes performance. Allport's 1924 definition places experiments at the center of the field's modern identity. The sources opened here do not describe other methods, such as surveys or field studies, so this guide does not characterize them.

Training and applications

The Society for Personality and Social Psychology states its mission as advancing the science, teaching and application of personality and social psychology for the benefit of all people. This guide treats social psychology as a research area, and the sources opened here describe no credential for it. Where practice titles or licenses exist, regulators in each jurisdiction set them, not this guide.

Boundaries and limits

Stroebe considers the broader pattern of experimental questions in the 1890s more important than who was first, so this guide claims no single founder or starting date. The society pages describe personality and social psychology together and do not mark a boundary between them. The sources opened here do not document the history of social psychology in other countries or regions, or specific university units.

  • Stroebe says that many authors in the 1890s tried to answer social questions with experimental methods, and that this pattern matters more than identifying who was first.
