Final answer:
Weber’s law states that the ability to detect a change in a stimulus is dependent on the strength of the original stimulus, where the just-noticeable difference is a proportional constant of the original intensity.
Step-by-step explanation:
According to Weber's law, the ability to detect a change in a stimulus depends not on the perception of depth, the law of visual organization, or the law of proximity, but on the strength of the original stimulus. Weber's law posits that the just-noticeable difference (jnd), or the minimum change in a stimulus that can be detected, is a constant proportion of the original stimulus's magnitude. This principle is significant in the study of sensation and perception, helping to understand how we respond to varying intensities of stimuli in our environment.
