Recent attention has been paid to the neurological, evolutionary, and developmental correlates of human self-face recognition. In the present study, we examined 12-, 18-, and 24-month-olds using eye tracking to determine if there was a unique visual scan path of faces for self-recognizers as compared to non-recognizers. Results indicated that overall, 12- and 24-month-olds have different scan-paths compared to 18-month-olds. Eighteen-month-olds have an increased number of fixations and fixation time spent on the eyes, mouth and top half of the face, while 12- and 24 month-olds have more fixations on the nose and bottom half of the face. Furthermore, self-recognizers have a generally unique scan-path of self-faces in comparison to non-self-faces, having increased attention to the upper features and mouth on the self-face. This distinction between age groups and self-recognizers presents significant implications for development and the progression of self-awareness.
