In the past few years, mobile EEG equipment has developed a lot and allows measurement of brain signals in almost any surrounding. Multichannel amplifiers are in the meantime not larger than a box of matches and everything can be sampled and stored on standard smartphones or an SD-card.
Up to now, we are systematically exploring mental states, such as e.g. mental fatigue in naturalistic work place simulations. Testing mental fatigue and workload, we set up a simulation of a logistic workplace where we tested older and younger participants with mobile EEG during a 4-5 hour work shift. They had to perform either a monotonous cognitive task, a self-paced cognitive task or a self-paced physical task in a predefined order. Self-assessment, behavioral performance and spectral measures of the EEG (before most alpha power) were analyzed. Younger participants showed declined performance before most in a monotonous cognitive task. Older adults, on the other hand, were overall impaired by inefficient information processing. This was visible in blink-related synchronizations of the EEG, a new measure to investigate cognitive processing in real life environments. Most recently, we started measurements with concealed round-the-ear electrodes in order to transfer those measures to real life. First validation studies demonstrate that most relevant cognitive components of the EEG are measureable with these electrodes. Thus, they seem to be an important steps towards cognitive neuroergonomics based on objective data.
Edmund studied Psychology at the University of Graz, Austria, between 1983-1990. He acquired his Diploma in 1990 on ‘Changes in Perception and arousal in schizophrenics and artists’, before undertaking a PhD in the ‘Investigation of organizational problems in stimulus selection and perception in schizophrenia’. In 1991 Edmund took up a Post-doctoral fellowship within the Neurology Department at the Medical University of Luebeck. In 1997 he became a Research Assistant at the Psychological Institute at the University of Tuebingen where he conducted research within the Clinical and Physiological Psychology department. In 2000 Edmund became Associate Professor and Head of the Max-Planck Junior Research Group, ‘Cognitive Psychophysiology of Action’, at the Max-Planck-Institute for psychological Research in Munich. He now divides his time as Professor of Ergonomics at the Technical University of Dortmund, Scientific Director Leibniz Research Centre for Working Environment and Human Factors, and, is a faculty member the Faculty for Psychology at the University of Bochum, Germany.
