_____ predicts that a power lifter cannot detect the difference between 300 and 301 kg but can easily detect the difference between 3 and 4 kg.

Question

Quizplus · Accepted Answer

Weber's law states that the proportional difference between two stimuli that can be detected is constant, rather than the absolute difference. In other words, the just noticeable difference (JND) between two stimuli is a constant fraction of the stimulus intensity. This is why a power lifter might not be able to detect the difference between 300 and 301 kg, but can easily detect the difference between 3 and 4 kg, even though the absolute difference is the same (1 kg).
