What is the difference between Weber's law and difference threshold?The just noticeable difference, also known as the difference threshold, is the smallest possible difference between two stimuli that can be detected at least half the time. According to Weber's law, this difference threshold is a constant proportion of the original threshold size.
Which of the following describes Weber's law?Correct answer: The just-noticeable difference between any two stimuli is proportional to the magnitude of those stimuli. Explanation: Weber's law states that the just-noticeable difference between any two stimuli is proportional to the magnitude of those stimuli.
What percentage of time must we be able to detect a stimulus for it to be our absolute threshold for that stimulus?The absolute threshold is the minimum amount of stimulation required for a person to detect the stimulus 50 percent of the time.
Who developed both the two point threshold and the concept of the just noticeable difference?Found by Ernst Weber, "the threshold at which two points of stimulation can be distinguished as such."
