Protocol to study how expectations guide predictive eye movements and information sampling in humans

Investigating eye movements provides a unique tool to explore how expectations influence information sampling in the visual domain. Here, we present a protocol for measuring predictive eye movements during face anticipation as well as fixations and dwell time during face recognition in humans. We describe steps for setting up two eye-tracking experiments. We then detail procedures for the measurement and analysis of eye-tracking data. For complete details on the use and execution of this protocol, please refer to Garlichs et al.¹.
