AbstractThe purpose of this paper is to advocate a shift in research and practice on organizational socialization towards one based on positive organizational behaviour (POB). First, we demonstrate how the prevailing perspectives of organizational socialization are based on a cognitive‐learning process that emphasizes information and knowledge acquisition. We then review the literature on POB and psychological capital (PsyCap) and argue that socialization processes should be designed to develop the PsyCap of newcomers. We offer a new approach to organizational socialization called socialization resources theory (SRT) and describe four broad socialization resources that can be used to develop newcomers' self‐efficacy, hope, optimism, and resilience. Finally, we discuss the implications of this approach for research and practice on organizational socialization. Copyright © 2010 ASAC. Published by John Wiley & Sons, Ltd.
