Monitoring mental fatigue in the ageing working population

Mental fatigue, during or after a period of prolonged mental workload, is a common phenomenon in our everyday lives. Mentally fatigued people generally respond more slowly and less accurately to stimuli in their environment, which potentially leads to dangerous situations. The aim of my research is to find ways to monitor mental fatigue in a working environment, and examine whether these methods should be adapted for different age groups. Although we already found that monitoring keyboard-based performance measures during typewriting can provide information about mental fatigue in both younger and older workers, office work does not consist of one task that remains the same throughout the day. During the symposium, I will elaborate on different measures (e.g., mouse usage, sitting behaviour) that might be susceptible to the effects of mental fatigue during non-typewriting tasks
