What kind of psychophysiological measurements are collected?
We have developed measurement protocols and indices of driver workload, stress and attention in collaboration with neurophysiologists in the Department of Psychology (University of Minnesota) and pioneers in driver psychophysiology at the University of Groningen. These protocols include measures derived from EEG, ECG, GSR, EOG, and EMG. Unique measures that have been validated by the HumanFIRST Program include (1) Evoked Response Potential (ERP) metrics and brain mapping to using an Odd-Ball Stimulus Paradigm to assess mental attention and resource processing, and (2) spectral analysis of heart inter-beat intervals to compute a metric of .10 Hz Sinus Arrhythmia to assess mental effort.
