Adult Cognitive and Non-cognitive Skills: An Overview of Existing PIAAC Data

As of summer 2019, more than 60 PIAAC datasets from participating countries worldwide were available for research purposes. These datasets can be differentiated, for example, in terms of their accessibility, the extent of the information provided, the population group in focus, and the design of the underlying study. PIAAC Public Use Files, for instance, are freely available and are therefore highly anonymised, whereas PIAAC Scientific Use Files are available only for scientific research purposes and provide access to more detailed variables. The majority of the PIAAC data are available as public use files, but some participating countries (e.g. Germany and the United States) have also made several scientific use files or other extended file versions available to the research community. Some of the available PIAAC datasets focus on specific population groups - for example, the incarcerated adult population in the United States. Regarding the design of the underlying studies, most available datasets are cross-sectional, but some longitudinal data already exist (e.g. PIAAC-L in Germany). The present chapter provides an overview of the structure, accessibility, and use of the PIAAC datasets available worldwide

Age diversity and learning outcomes in organizational training groups: the role of knowledge sharing and psychological safety

This study advances theorizing on human resource development by conceptualizing a training group’s age diversity composition as an antecedent of participants’ learning outcomes in organizational training courses. Drawing from social identity theory, we propose that a high age diversity of the training group can inhibit participants’ learning outcomes because individuals are less likely to share knowledge than in age-homogenous groups. Furthermore, we expect that psychological safety serves as a buffer, such that participants who perceive a high level of psychological safety in a training group will engage in knowledge sharing and consequently report high learning outcomes, regardless of the training group’s age diversity composition. We tested the proposed moderated mediation model in a sample of 211 employees participating in an interactive oneday training at an automobile manufacturer. We found that perceived age diversity, but not objective age diversity, was negatively linked to participants’ learning outcomes and that this relationship was mediated by knowledge sharing. Participants’ perceptions of psychological safety served as a buffer against the negative effect of perceived age diversity. We discuss implications for the conceptual understanding of learning as an active process shaped by the training group and encourage scholars to broaden their understanding of training design elements
