Quizplus · Accepted Answer

A difference threshold, also known as a just noticeable difference, is not a fixed value but rather a constant proportion. This means that the minimum difference required to detect a change in a stimulus dimension, such as weight, is proportional to the size of the original stimulus. For example, if a weight of 10 pounds is being compared to a weight of 11 pounds, the difference threshold might be 1 pound (10% of the original weight). However, if a weight of 100 pounds is being compared to a weight of 101 pounds, the difference threshold might be 10 pounds (10% of the original weight).
