The purpose of this investigation was to determine the effect of prior experiences on cognitive demands at initial learning. Drone operation was the initial learning experience with videogame use as a prior equivalent experience. The NASA Task Load Index was used to measure cognitive demand. Participants operated drones at three instances over two weeks. A mixed ANCOVA suggested a significant interaction between videogame player group and time in explaining the mental demand scores: F(2, 10) = 7.15, p = 0.012. Spatial ability, measured as a covariate, was significantly related to mental demand: F(1, 5) = 10.96, p = 0.021. Results suggest cognitive load can decrease over time with repeated use of the skill when there is no prior experience.
