options

1. by introducing different sounds while conducting the test
2. by using different shapes of lights for each receptor type
3. by using colored versus white lights to differentially activate the rods and cones
4. by alternating the brightness using flashing lights in order to preferentially activate one receptor type rather than the other
5. by changing the color of the room during the experiment
6. by asking participants to blink rapidly before the test
7. by asking participants to cover one eye while performing the comparison tasks
8. by changing the location of the test light from the focal point to the periphery

question

Researchers studying vision use various methods to investigate human perceptual experience. Research on spectral sensitivity of the rod receptors (scattered throughout the retina) and cone visual receptors (mainly concentrated in the fovea area of the retina) highlights the relationship between perception and physiology. Signal detection methods have been used to measure the differences in how perception adjusts to low-light environments. Participant responses can be plotted based on sensitivity versus length of time in the dark. The dark adaptation curve can be plotted showing how rods and cones differ in their sensitivity to light over time. The following graph shows a plot of three calculated dark adaptation curves. <image 1> The dark adaptation curve can be plotted by asking participants to fixate on a specific point and then using signal detection methods with a test light. What is the MOST likely way that researchers would be able to isolate the responses of each receptor type, based on the physiology of the eye?
