摘要：	This report details a three year effort to expand our understanding of pupillary dynamics and improve the methods by which cognitive scienceresearchers measure pupil diameter. Researchers established in the early 1960s that pupil diameter increases during cognitive effort, and thatthe size of this increase is proportional to the magnitude of that effort. More recent research has suggested that pupil size at rest is significantlycorrelated with cognitive ability. However, after conducting several studies investigating resting pupil size and cognitive ability, with a combinedsample of over 500 active duty personnel, we were unable to replicate this finding; calling this work into question. Additionally, these resultswere obtained after we developed a new technique to improve the accuracy of remote eye tracking systems by computing a known referencefor each participant, using a fiducial marker and inter-pupillary distance. The lack of ground truth has been a long-standing issue for remoteeye tracking systems and this research effort provided a solution. Furthermore, although we found no link between pupil size and ability we didfind that the degree of variability is correlated with an individual’s cognitive ability. This report discusses future applications of pupil diametermeasurement for the DoD.
