Many studies have examined group pressure and its effect on an individual. A study was undertaken to investigate the influence of a majority upon subjects and its effect upon long term memory. Undergraduate students (N=18) were selected and randomly assigned to either a treatment or control group. Each subject watched a 10-minute segment from a movie and then answered questions about the movie segment. Treatment subjects were questioned orally with three confederate subjects who responded to the questions before the subject responded and who lied on 8 out of 20 questions. Control subjects answered the same questions in a written questionnaire. Each subject returned in one week to answer the standard written questionnaire. The results indicated that treatment subjects' performance was much poorer than that of control subjects during the initial session. Their performance improved in the recall testing session but remained poorer than that of the control subjects. (Author/NB)
