Primacy Effects in Information Processing Behavior -- The Individual Versus the Group. Paper No. 334.
This paper describes an investigation of some effects of group interaction and consensus on information processing behavior. When individuals were asked to assess a hypothetical situation on the basis of various sequentially received data, a definite primacy effect was observed; individuals gave more weight to data they received first. This primacy effect, however, was vitiated by group interaction. The study also showed that after group discussion and consensus, individual opinions were closer to the group assessment than to the individual's original assessment. A tendency toward convergence within groups was also observed, although it was not statistically significant. Responses of the subjects were compared to the Bayesian norm and to utility and trustworthy data. A number of statistical tables and graphs summarize the findings of the study. (Author/JG)
