Field Study of Stress: Psychophysiological Measures During Project Supex.

Abstract

This study, conducted in collaboration with the Combat Developments Experimentation Command (CDEC) in a planned project entitled SUPEX, evaluated psychophysiological recording techniques in a stressful field situation. Continuous recordings of heart rate and general muscle tension were compared with performance suppression measures obtained by CDEC. Selected test scales of perceived anxiety/stress were administered to the participants. These data were compared with both the performance and the psychophysiological measures. Changes in heart rate were sensitive indicators both of anticipation and response to weapon fire. Both the rate of weapon fire and size of direct fire weapons directly influenced heart rate while indirect fire weapon affected heart rate only marginally. Several parameters of heart rate correlated significantly with performance measures. General muscle tension recordings proved to be unreliable utilizing the current procedures. The perceived scales evaluated the current state of the individual, but they were not good predictors of performance or heart rate activity. (Author)
