Mental workload measurement, the case of stock market traders

The main objective of the paper is to focus on generating factors of mental workload for the case of stockbrokers. Based on a survey targeting 77 Tunisian stockbrokers, we found that mental workload varies according to factors related to performed task demands. As a multidimensional phenomenon, we found that mental workload can be intensified by other psychosocial and individual factors. Even though we have tested all three groups of factors as direct antecedents to mental workload despite the assumption that psychosocial and individual factors could be operationalised as moderators. We pointed out that in a global model task demands, psychosocial and individual factors were significantly related to mental workload level. As we hypothesised emotional demands and emotional dissonance could be dimensions of task demands, we also found that emotional demands are correlated to mental workload level.
