Document Summary

Colour: not a physical property, it is made up by the brain. Green filter: nose and stars appear equally bright but are actually a very different colour. Problem of univariance: an infinite set of different wavelength-intensity combinations can elicit exactly the same response from a single type of photoreceptor. It"s better to talk about s m and l cones rather than red, green and yellow cones. Scotopic: referring to dim light levels at or below the level of bright moonlight. rods are sensitive to scotopic light levels. All rods contain same type of photopigment molecule: rhodopsin. Newton: prisms break up sunlight into spectral components. Colour vision is based on 3 photoreceptors sensitive to particular ranges of wavelengths. Metamers: any pair of stimuli that are perceived as identical in spite of physical differences. In terms of light: different mixtures of wavelengths that look identical.

Critics of the trichromatic theory of colour vision have indicated that this theory has a major limitation. Which of the following statements MOST accurately reflects this limitation? A) Young and von Helmholtz were incorrect in assuming that cone photoreceptors in our retina are maximally responsive to a specific wavelength of light B) The trichromatic theory cannot explain the phenomenon of visual after-effects C) Rod photoreceptors in our retina, not cones, are responsible for the neural coding of colour D) Research has determined that there are actually six types of cones in the retina, rather than three as proposed by Young and Helmholtz E) Trichromatic theory cannot explain sensory adaptation

33. The theory of color vision that proposes that the human eye has three types of receptors sensitive to different wavelengths is: a. the tridetector theory. c. the trichromatic theory b. the opponent process theory. d. the tripartite theory.

1. Zachary was born with a rare visual defect. He has no cone photoreceptors in his retina, there are only rods. Assuming that all other aspects of his visual system are normal, which of the following would characterize Zachary's vision?
