Voluntary and involuntary movements of the eyes, including convergence, divergence, fixation, and the saccade. In studying eye movements in the 1950s and 1960s, Yarbus found that in looking at images we tend to look most at areas with high contrast, fine detail, and signs of life, and with faces we give special attention to relationships between key features. However, scanning patterns depend above all on our current purposes and interests. He found that asking different questions about an image produced very different scanning patterns and points of fixation.
