| description | Abstract Studies have demonstrated connections between eye movements and attention shifts. However, little is known about the general factors that contribute to the self-consistency of idiosyncratic scanpaths as a function of attention shifts over time. The present work repeatedly measured human eye movements at various time intervals that ranged from less than one hour to one year between recording sessions. With and without task context, subjects observed multiple images with multiple areas of interest, including their own sporadically interspersed facial images. As reactions to visual stimuli, the eye movements of individuals were compared within and between subjects. We compared scanpaths with dynamic time warping and identified subjects based on the comparisons. The results indicate that within-subject eye movement comparisons remain more similar than between-subject eye movement comparisons over time and that task context and self-referential stimuli contribute to the consistency of idiosyncrasies in attention shift patterns. |
