Individual Differences in Eye-Movement Patterns

Abstract
The reliability of individual differences in patterns of eye fixation during a size-estimation task was studied in normal adults, each tested twice. The most stable measures not specifically related to the stimulus configuration appeared to be the number of fixations per unit time; measures related to dispersal of looking were unreliable. Data on where S looked, the duration of each fixation and the distance between fixation points appeared to follow first-order Markov processes and the transitional probabilities appeared to be individual characteristics stable over time.
