Absolute threshold minimal intensity needed to just barely detect a stimulus (50% on trials) Difference threshold refers to the minimum difference for a person to be able to detect the difference half. The jnd of a stimulus is a constant proportion despite variations in intensity. Minimal change in a stimulus that can be detected.
