During a spectral sensitivity test, a researcher projects a light onto the periphery of a participant's retina. What is the researcher most likely testing?
A) the sensitivity of the participant's cone vision
B) the sensitivity of the participant's rod vision
C) the sensitivity of the participant's binocular vision
D) the participant's visual acuity

Question

Quizplus · Accepted Answer

The researcher is most likely testing the sensitivity of the participant's rod vision, because the periphery of the retina contains mostly rods and few cones, which are responsible for low-light vision. This test assesses the participant's ability to detect dim light in the periphery of their visual field, which is a function of their rod photoreceptors.
