Abstract:

An indirect measurement of mental effort in interpreting an aircraft instrument was made using changes in pupil diameter and the latency of dilation as measures. Significance was found in latency of dilation across levels of interpretation difficulty, while no significance was found for percent changes in pupil diameter. Results also showed a moving base-line pupil diameter for all subjects across trials suggesting arousal decrement for the first half of the experiment, with a lesser effect for the latter half of the experiment.
