ABSTRACT

Workload is a rather ambiguous concept. Subconcepts like cognitive load, informational load, attentional load, and emotional load are not based on uniformly used theoretical considerations. The distinction between stress, strain, and workload is difficult to make, especially in real work settings. Psychophysiological measurements during work are influenced by a number of psychological and physiological factors due to intrasubject and task parameters in the interaction of subject with task. Psychological factors include motivational and emotional processes, embedding workload into cognitive-affective-physiological framework models. Aspects of these dynamic processes can be studied with electroencephalography (EEG) at a high time resolution. EEG is an appropriate and elaborate method to investigate or monitor general arousal, and specific cognitive and affective processes of the brain.
