Abstract

The study examined how raters integrated the informations of 360 degree feedback. It was tested how the informations from multiple sources(self, supervisor, subordinate and co-worker) influenced raters' rating and modification of it, which information was more influential among the informations from multiple source-multiple raters, and how the influence was differed depending upon the direction and the magnitude of the discrepancy between the informations of 360 degree feedback and raters' rating. In results, the informations significantly influenced raters' rating and modification of it, and the impact of the rating of peer and subordinate was stronger than that of supervisor and self. Moreover, it was testified that the tendency to modify raters' self-rating downward when they received lower rating scores from multiple source-multiple raters was stronger than the tendency to modify raters' self-rating upward when they received higher rating scores from them. There was the interaction effect between the direction and the magnitude of the discrepancy among ratings. The causes of the results and implications were discussed.
