I work at the Netherlands Organisation for Applied Scientific Research TNO (location Soesterberg) and for one day a week at Radboud University where I hold the chair ‘Mental State Monitoring’. I am intrigued by the question of how we can extract information about cognitive and emotional state from physiological signals and implicit behavior outside the lab, and how we can sensibly and responsibly harness this information in applications that benefit people’s well-being and performance. We know from neurocognitive, psychophysiological and psychological research that different types of measured signals (e.g., EEG, skin conductance, eye movements and facial expression) are associated with different types of underlying cognitive and emotional processes. In addition, these different types of signals can inform us about the individual’s current task or context which may be used to better interpret the various signals. Therefore, we usually follow a multi-modal approach. Again with the application in mind, this multi-modal approach includes simultaneous use of wearables and high-end equipment, sometimes resulting in surprisingly good performance of relatively simply measurable signals.
