• The aim of this study is to evaluate the influence of subjective assessments of environmental conditions on mental workload. A sample of 238 office workers assessed levels of perceived mental workload and the adequacy of certain environmental conditions of their working context (temperature, lighting, noise, spatial distribution and hygienic conditions) using the Subjective Mental Workload Scale. The effect of these five environmental conditions on five mental workload factors was tested by means of multivariate analysis of variance. Results show that the perception of noise, spatial distribution and hygienic conditions are associated with greater subjective mental workload in three specific dimensions of mental workload: task characteristics, temporal work organization and working rate
