Question

Quizplus · Accepted Answer

Adaptation refers to the process in which receptors become less sensitive to a stimulus as exposure to that stimulus increases. This means that receptor sensitivity changes depending upon the intensity of the stimulus. For example, if you are in a dark room for a long time, your eyes will adapt by becoming more sensitive to the available light. Similarly, if you are exposed to a loud noise for a prolonged period, your ears will adapt by becoming less sensitive to that noise over time.
