Weber's Law states that a just noticeable difference in stimulus magnitude is proportional to the original stimulus magnitude. This means that the larger the initial stimulus, the larger the change needed for it to be perceived as different. For example, a 10-pound weight may need to be increased by 1 pound to notice a difference (10% increase), whereas a 1-pound weight may only need to be increased by 0.1 pound (10% increase) in order to be noticeable.
