Just-Noticeable Difference: For any of our sensory dimensions (smell, sight, hearing etc), just-noticeable difference is the amount of change that humans can detect. Research has proven that the JND for price tends to be between 20 to 25%. When we try to compare two different objects to see if they are the same or different on some dimension (e.g., weight), the difference between the two that is barely big enough to be noticed is called the just noticeable difference (JND). For example, imagine that a weight is 100 kg. If the brightness needed to yield the just noticeable difference was 110 then the observer's difference threshold would be 10 units (i.e., delta I =110 - 100 = 10).
