This study drew from two distinct paradigms: the social cognitively based emerging field of positive organizational behavior or POB and the more established behaviorally based area of organizational behavior modification or OB Mod. The intent was to show that both can contribute to complex challenges facing today's organizations. Using a quasi-experimental research design (N = 1,526 working adults), in general both the recently recognized core construct of psychological capital (representing POB) and reinforcing feedback (representing OB Mod), especially when partially mediated through a mastery-oriented mindset, were positively related to problem solving performance, reported innovation, and subsequent psychological capital. The implications for theoretical understanding and practice conclude the article. (Contains 2 figures.)
