Quizplus · Accepted Answer

The absolute threshold is the smallest intensity of a stimulus that can be detected 50% of the time. Weber's law states that for a difference to be noticeable, it must be a constant proportion, whereas the difference threshold is the smallest difference between two stimuli that can be detected. The sensory threshold is not a specific psychological term.
