Which of the following does not occur after adaptation to a high-contrast, high spatial frequency grating:
A) Contrast threshold elevation for high spatial frequency gratings
B) Increases in the apparent spatial frequency of higher spatial frequency gratings
C) Decreases the apparent spatial frequency of lower spatial frequency gratings
D) Contrast threshold elevation for low spatial frequency gratings

Question

Quizplus · Accepted Answer

After adaptation to a high-contrast, high spatial frequency grating, there is typically a decrease in contrast threshold elevation for high spatial frequency gratings (A), an increase in the apparent spatial frequency of higher spatial frequency gratings (B), and a decrease in the apparent spatial frequency of lower spatial frequency gratings (C). However, there is no increase in contrast threshold elevation for low spatial frequency gratings (D) after adaptation to a high-contrast, high spatial frequency grating.
