Abstract:This study set out to examine the relationship between performance development and electrodermal activity (EDA) during a vigilance task. EDA responses were recorded at two locations, the palm and the wrist, with Q-Sensors. 15 student participants were instructed to observe moving arrays of lines for approximately 40 minutes of time. Their watch contained 16 deviant lines, which served as signals and had to be reported by pressing keyboard buttons. It was anticipated that a characteristic decline in performance, commonly referred to as vigilance decrement, would appear. This was not the case when detection performance of signals was considered. Reaction times decreased as a function of time on task. The reason for these changes in reaction times could not be ascertained by this study. Given the scarcity of supporting evidence for a vigilance decrement, a relationship of said phenomenon to the EDA measures could not be established. EDA was found to be more reactive at the palm location. Observed developments of the EDA recordings could be attributed to task or participant characteristics. Future iterations of the same experiment with changed parameters might be more successful in creating the fundamental feature of this study: a vigilance decrement.
