B)largest difference in the magnitude of two stimuli that an observer can reliably detect

Question

Quizplus · Accepted Answer

The difference threshold, also known as the just noticeable difference (JND), refers to the smallest difference in the magnitude of two stimuli that an observer can reliably detect. This is an important concept in psychophysics, as it allows researchers to study how sensitive the human senses are to changes in stimuli.
