The deaf group looked at the eyes more frequently and for longer duration than the nose whereas the hearing group focused on the nose (or the central region of face) more than the eyes.
However, it is also possible, and perhaps more parsimonious, to explain these effects as naturally arising from partially overlapping distributions in a single face space of the representations of male and female faces, if aftereffects have some selectivity for the region of face space in which they are evoked (Figure 4).
Recent findings relating OT to action imitation and to the visual processing of the eye region of faces point to mimicry as a mechanism through which OT improves processing of emotional expression.
They found that East-Asian adults tended to fixate on the nose region of faces when scanning own-race faces, differing from the fixation patterns produced by Caucasian adults that focus strongly on the eyes.

In contrast to monkeys with two copies of the long allele (L/L), monkeys with one copy of the short allele of this gene (S/L) spent less time gazing at face than non-face images, less time looking in the eye region of faces, and had larger pupil diameters when gazing at photos of a high versus low status male macaques.
Chimpanzees, Pan troglodytes, have a bias towards attending to faces more than other components in visual scenes, as humans do, although the bias is not as strong in chimpanzees (Kano & Tomonaga 2009), and the sequential fixations on the eye region of faces that are characteristic of humans are absent (Kano & Tomonaga 2010).
However, they are found to be sensitive to noise because of the fact that they are thresholded exactly at the value of the central pixel especially in near-uniform and smooth regions of face images like cheeks or forehead.
The simile classifiers are binary classifiers trained to recognize the similarity of faces, or regions of faces, to specific reference people.
Furthermore, both humans and rhesus macaques attended to eye regions of conspecific faces but not to the eye regions of faces of other species [32].
We examined infants' visual attention to the three major face features, specifically the eyes, nose, and mouth, because they are high-contrast regions of faces that carry important information for face identity [28] as well as for interpersonal communication [29].
