  1. just-noticeable difference

    The just-noticeable difference (JND), also known as the difference threshold, is the smallest change in a sensory input that a person is capable of noticing. This could apply to any sensory perception such as sound, light, weight, pressure, etc. It is based on Weber's Law, which states that the JND is a constant proportion of the original stimulus. In other words, whether a change in a stimulus can be detected will depend on the intensity of the original stimulus. Hence, the sensitivity to change in a stimulus often depends on its context or background.
