Question

Question restatement: Which of the following statements about human color vision is/are true?

Option a: 'Opsins are photosensitive (light-absorbing) pigments contained in the photoreceptors.' This is accurate. Opsins are the protein components bound to retinal that detect specific wavelengths of light in photoreceptor cells (rods and cones), forming the basis of phototransduction. The statement correctly identifies opsins as light-absorbing pigments in photoreceptors.

Option b: 'We have much worse color vision in our peripheral visual field than our central visual field.' This is generally true. The central vision (fovea) has a high concentration of cone photoreceptors with color sensitivity, while the peripheral retina has fewer cones and relatively more rods, leading to reduced color discrimination in the periphery compared with the center.

Option c: 'Color-hue perception can be influenced by high-order cognitive processes like language.' This is supported by psychophysical and cross-cultural studies showing that language and linguistic categorization can influence the way people perceive and label colors, indicating top-down cognitive effects on color perception beyond purely bottom-up sensory input.

Option d: 'A and C' This combines A and C. Since both A and C are true, this statement is true as a composite assertion. However, it does not address B directly.

Option e: 'All of the above are true of human color vision.' This asserts that every prior statement (A, B, C, and the implication in D) is true. Given that A and B are correct and C is supported by evidence, and D merely restates a subset that is true, this all-encompassing option is consistent with current understanding of human color vision.

Overall analysis: Each of A, B, and C reflects established aspects of color vision. D would be true insofar as it claims A and C, which are correct. E asserts that all listed statements (including B and the composite D) are true, which they are based on current knowledge. The composite structure of the options means the most comprehensive true statement is E, since it encompasses A, B, and C (and aligns with the truth of D by virtue of containing A and C).
