Electronic performance appraisals: The effects of e-mail communication on peer ratings in actual and simulated environments

Abstract

Across three empirical studies, this paper explores the effect of using e-mail as a communication medium (versus pen-and-paper) when conducting performance appraisals of peers. The notion put forth by Media Richness Theory that paper-form and e-mail media should be considered identical for conveying this information was theoretically challenged and differences were empirically supported. Using two different settings, results demonstrate that evaluators offered more negative appraisals of their peers when using e-mail than when using traditional paper-form methods. Reduced feelings of social obligation in the e-mail condition were found to mediate this relationship, indicating that social psychological processes can influence the effects of different media on peer ratings.
