Abstract
Investigation of infant eye gaze behavior previously relied on subjective methods to understand infant visual preference. This study aimed to determine if differences in infant eye-gaze patterns existed between familiar and unfamiliar faces and how these patterns may relate to attachment, early engagement, and language development using an objective measure, electronic eye-tracking. To determine the existence of regularities, the eye-gaze behaviors of a 3-month-old infant were recorded using the Tobii X120 eye tracker. This preliminary report details patterns observed in a single participant, as one example of the larger study, in which analyses identified similar patterns among five participants.
