Answer:
The answer is d. perceptual adaptation.
Explanation:
Perceptual adaptation refers to the decrease in response to a perceived stimulus. For example, a person who's just started wearing glasses might have trouble with spacing at first: objects seem further or closer, the floor seems to move around, and the person could even get headaches. However, after a few weeks the person adapts to the new perception of the environment.
Perceptual adaptation is important for learning, as it allows people to focus their attention better.
