The Effects of Ageing on Creative Performance Trajectories

Previous research has demonstrated that job performance initially increases, plateaus, and then eventually declines. A major factor that may be relevant for explaining these performance changes is the ageing process. This study examined the within-person effect of ageing on changes in a specific type of job performance (creative performance), and whether the age of career onset is a moderator. These questions were investigated using two measures of creative performance data spanning several decades from 300 authors and analysed using hierarchical linear modelling (HLM) techniques and hierarchical generalised linear modelling techniques (HGLM). The results revealed an inverted U-shaped relationship between time and creative performance, and an inverted U-shaped relationship between ageing and creative performance when controlling for work experience. The age at which an individual starts their career was a significant moderator of the shape of performance trajectories. Findings are discussed in relation to how this study contributes to the literature on performance trajectories and the effects of ageing on performance.     

Consequences of Supervisor Knowledge Hiding in Organizations: A Multilevel Mediation Analysis

Drawing on the theoretical framework of social cognitive theory, our study explores the multilevel mediation model in which moral disengagement (level-1) mediates the direct relationships between knowledge hiding by supervisors from subordinates (KHSS: level-2) and supervisor directed organizational citizenship behavior (SOCB: level-1) and supervisor directed silence (SS: level-1). Drawing on multi-sourced, multi-timed, and multilevel data of 306 subordinates nested within 83 supervisors, multilevel structural equation modeling (ML-SEM) was used to test the proposed model. The results demonstrate that KHSS, first, fosters subordinates’ moral disengagement, which in turn reduces their SOCB and enhances their SS. Our findings offer several useful theoretical and managerial implications of the negative consequences of supervisor knowledge hiding in organizations. As one of the first studies to provide empirical evidence for the existence of supervisor knowledge hiding (i.e. KHSS), this research highlights the consequences of KHSS on subordinates’ moral disengagement, SOCB, and SS.     

Is Grit Hurting You? The Dark Side of Psychological Resources in Goal Pursuit

This article presents a study of the curvilinear role of psychological resources during goal striving through an interactive model linking work goal progress to a valued resource. Specifically, we explore the nonlinear relationship of grit with work goal progress. Additionally, we test the moderating role of perceived organizational support (POS) for this relationship. We hypothesized that an employee’s goal pursuit is not merely contingent on the excessive availability of the selected resources but instead might be an outcome of interaction between personal resources and the environment. Our sample comprises 293 university professors working in the United States who completed questionnaires at two time points. The study findings confirm the curvilinear role of grit in predicting work goal progress. Furthermore, the moderating role of POS on the nonlinear relationship between grit and work goal progress is confirmed to be significant. We discuss the theoretical implications for industry concerning performance and self-regulation based on our findings.
