The effects of organizational citizenship behavior on performance judgments: A field study and a laboratory experiment.

Abstract

The process linking organizational citizenship behavior (OCB) with performance judgments was investigated in a field and a laboratory study. In the field study, managers rated the task performance and OCB of 148 subordinates. In the laboratory research, 136 students viewed and rated videotaped segments of teaching performance that demonstrated either high or low task performance and high or low OCB. In both studies, liking and perceived affective commitment mediated the relationship between OCB and overall evaluation. Liking also mediated the relationship between OCB and reward recommendations. Further, the field study indicated that the causal motive attributed by the manager for the employee's OCB mediated the relationship between OCB and overall evaluation.
