The Use of Near-Infrared Spectroscopy in Measuring General Autonomic Arousal
Coyle, S. and Ward, T. and Markham, C. and Roche, B. and McDarby, G. and McLoone, S. (2003) The Use of Near-Infrared Spectroscopy in Measuring General Autonomic Arousal. In: World Congress on Medical Physics and Biomedical Engineering, 2003, Sydney, Australia.
The use of electrodermal activity (EDA) has become the most widely used measure in psychophysiological studies and has been identified as perhaps the best general index of autonomic activity [Dawson et al 1990]. Recent work in near-infrared (NIR) technology, however, has made possible the development of another psychophysiological recording device that may match EDA as a general index of autonomic arousal.
