Weber's law can best be explained as
1
The principle that the 'just-noticeable' difference for any given sense is a constant proportion of the stimulation being judged
2
The idea that the best amount of energy detected in a stimulation only occurs once
3
The smallest change in stimulation that can be detected 50 percent of the time
4
The theory that all stimuli respond to the same sensations through the process of creating meaningful patterns
