The doctrine that there are functionally two distinct ways in which our eyes work, the photopic, associated with the cones, and the scotopic, associated with the rods, is known as the ______ theory of vision.
A)Young-Helmholtz
B)duplex
C)inverse
D)retinal-macular

Quizplus · Accepted Answer

The given statement clearly describes the duplex theory of vision, which proposes that there are two separate systems in the eyes responsible for processing different types of visual information - the photopic (cone-based) system for high-resolution and colour vision, and the scotopic (rod-based) system for low-light and motion detection. The Young-Helmholtz theory, also known as the trichromatic theory, describes the three types of colour receptors in the retina, while the inverse theory relates to the interpretation of sensory information in the brain. The retinal-macular theory refers to the organization of the retina based on the distribution of photoreceptor cells.
