PSYCH 1XX3 Lecture Notes - Lecture 6: Color Vision, Retina, Occipital Lobe
Document Summary
Objects don"t inherently have a colour, the colour we see is due to certain wavelengths of visible spectrum being reflected into our eyes. These reflected wavelengths trigger specific patterns of response in our brains that give rise to our subjective experience of color. Color is a creation of our mind. This subjective experience relates to how the different wavelengths of light affect certain cones in our retina. Color adds richness to our visual experience. The bull see a piece of grey moving clothes so respond to the motion and not the red cloth. Many birds, fish, reptiles and insects have excellent colour vision. Among mammals, color vision is limited to primates including humasn. Dog, cats and bulls only see in shades of grey. Primates have 3 types of cone in the eye that are used for colour vision. Well suited to distinguishing red and yellow against a green background help in foraging for fruit in bushes and trees.
