Question

1- Explain in your own words the three theories of color vision. How are they similar to each other, and how are they different from one another?

2- Imagine you are at an art museum admiring a very colorful painting. Trace the pathway that information about this painting would take, from the retina to the appropriate area of visual association cortex.

3- Now imagine you are at a Cirque du Soleil show watching the perfomers’ incredible movements, and do the same.

PLEASE ANSWER WITH DETAILES

Answer 1

1. There are two major theories that explain colour vision. According to trichromatic thoery (Young-Helmholtz theory), there are three types of cone cells in the retina that are responsible for the perception of colour. One receptor is sensitive to the color green, another to the color blue and a third to the color red. According to Opponent processing theory by Ewald Hering, there are three different mechanisms in the retina, each producing two opposite quakities of sensation. They are blank and white mechanism, red and green mechanism and, yellow and blue mechanism.
