Question

Lois was not pleased when she realized that the box of candies did not contain as many candies as it used to. When she compared the package to the previous package she had bought, the changes were hardly discernible. This is an example of the use of Weber's law.

A) Weberian Candy Perception
B) Weber's Discrimination Principle
C) Just-Noticeable-Candy-Difference
D) Candy Package Sensitivity

Answer 1

Option (C), Lois's difficulty in noticing the reduced amount of candies in the box exemplifies Weber's Law, which states that the just-noticeable difference in a stimulus is proportional to the magnitude of the original stimulus.

Step-by-step explanation:

When Lois realized that the box of candies did not contain as many candies as it used to, yet the changes were barely noticeable, it exemplified the principle known as Weber's Law. According to this law, the just-noticeable difference (or the smallest change in stimulus intensity that can be detected) is proportional to the original intensity of the stimulus.

This means that in the case of the candies, the slightly smaller quantity became difficult to distinguish because the difference in number was too small relative to the original amount of candies.

This is related to the concept of the just-noticeable difference changing in relation to the stimulus intensity; for instance, it's easier to notice the difference between 1 and 2 pounds than it is to discern the difference between 20 and 21 pounds as the larger baseline makes the relative change smaller.
