What is the significance of the sclera (the whites) of our eyes? This is a question that researchers have been interested in for some time now. Recently, a research team led by Dr Fuhimiro Kano, a comparative psychologist, has successfully deciphering the mystery: Through its basic colour properties, the white of the eye contributes decisively to the visual appearance of directions of gaze.
When we talk to other people, we make contact with one another. We know exactly who is looking at and which unspoken messages the person is displayed using the "language of their eyes" or their object, according to Kano. During this process, humans have probably evolved a unique communicative approach to distinguish the person''s eyes from other people. This study supports the use of photometry to describe objects and behaviors.
Humans and chimpanzees are able to perceive the human eye better than the chimpanzees.
The results from Kanos research group''s experiments with humans and chimpanzees the closest relatives of humans. During the experiment, humans and chimpanzees were presented with visual representations of both species two with a straight line of eyes, one viewing to the side. If they pointed to the picture with the shifted eye, they got a reward. Kano says: ''We found that both humans and chimpanzees distinguished human eye-gaze patterns better than those of chimpan
When the contrast polarity of the chimpanzee eye was reversed, it was less noticeable, particularly when the iris had a human-like sclera, which helps the eye-gaze direction visually assist individuals. Our findings thus reinforce but also reinforce the basis of Kano''s speculation.
For the first time, the three researchers chosen a cross-species technique. Both chimpanzee and human participants presented eye images. Kano is a major helper in distinguing between several other concepts.
