The paper is a report of research designed to investigate the effect of repeated glare on human performance of a tracking task. The experiment used an EAI 680 computer to create the tracking task as well as to record the experimental data. Subjects were dark-adapted for thirty minutes and then performed the tracking task for a half hour fun period. During the run the subject experienced four flashes from a glare source. A control run, with no dark-adaption or intermittent flashes, was performed by all five subjects. Performance was measured by the time required to reach a predetermined level of error, while a biological factor was measured by the lowest galvanic skin resistance value during the time period prior to reaching the error level. Statistical analysis showed both the flash-time factor and the condition flash- time interaction to be significant at the 95 level of confidence. Graphical analysis showed the subjects performance to increase with time while operating the tracking task under the glare condition.
