_____ predicts that a power lifter cannot detect the difference between 300 and 301 pounds but can easily detect the difference between 3 and 4 pounds.
A)Weber's law
B)Signal detection theory
C)Size constancy
D)Gestalt theory

Question

Quizplus · Accepted Answer

Weber's law states that the ability to detect the difference between two stimuli is proportional to the magnitude of the stimuli. In this case, the power lifter cannot detect the difference between 300 and 301 pounds because they are very similar in magnitude. However, the lifter can easily detect the difference between 3 and 4 pounds, which are much further apart in magnitude.
