This final report attempts to summarize the major findings of three and one-half years of research in the area of understanding and accurately judging others. The author's research on person perception focuses on the use of sound motion pictures of interviews as the primary stimulus and vehicle for the research. Subjects used for these studies were usually college students from psychology classes. There are three major sections or topics for this research: (1) assessing the validity of verbal and non-verbal cues in accurately judging others; (2) effects of money, anticipation and competition upon judging scores and self-reports of motivational arousal; and (3) social stereotyping and its relationship to accuracy in person perception. Results indicate that accurately perceiving and judging another is a complex task affected by many variables, and the difficulty in decoding them depends on the transparency or opaqueness of the person being judged. In addition, according to the authors, people can be trained to be better judges of others. (GMF)
