Quizplus · Accepted Answer

ΔI represents the change or amount that must be added to the standard intensity to produce a just noticeable difference (jnd). This is important in the context of Weber's law, which states that the smallest noticeable difference in a stimulus (jnd) is proportional to the initial intensity of the stimulus. Thus, ΔI is used to calculate the jnd as ΔI/I, where I is the intensity of the standard stimulus.
