Centro de Documentación de Fundación MAPFRE - The Active learning hypothesis of the job-demand-control model : an experimental examination

Notas: Sumario: The active learning hypothesis of the jobdemandcontrol model [Karasek, R. A. 1979. Job Demands, Job Decision Latitude, and Mental Strain: Implications for Job Redesign. Administration Science Quarterly 24: 285307] proposes positive effects of high job demands and high job control on performance. We conducted a 2 (demands: high vs. low) × 2 (control: high vs. low) experimental office workplace simulation to examine this hypothesis. Since performance during a work simulation is confounded by the boundaries of the demands and control manipulations (e.g. time limits), we used a post-test, in which participants continued working at their task, but without any manipulation of demands and control. This post-test allowed for examining active learning (transfer) effects in an unconfounded fashion. Our results revealed that high demands had a positive effect on quantitative performance, without affecting task accuracy. In contrast, high control resulted in a speedaccuracy tradeoff, that is participants in the high control conditions worked slower but with greater accuracy than participants in the low control conditions.Registros relacionados: En: Ergonomics : the international journal of research and practice in human factors and ergonomics. - Oxon [United Kingdom] : Taylor & Francis, 2010- = ISSN 0014-0139. - 06/01/2014 Volumen 57 Número 1 - enero 2014 Outras classificações: 875
