Question

In making a large pot of chili for a family reunion, you find that you have to add 1 onion to your pot of chili that already has 5 onions mixed in it to notice a difference. According to Weber's Law, how many onions would you have to add to notice a difference if you are making twice as much chili with 10 onions?
a. 1
b. 2
c. 4
d. 5

Answer 1

According to Weber's Law 2 onions should be added to notice the difference.

The correct option is b. 2

Explanation:

Weber’s law deals with hypotheses in psychophysics. The law explains the relation between the actual change in a physical stimulus and the perceived change.

Weber’s law was proposed by a German philosopher Gustav Theodor Fechner. Fechner dealt with psychophysics and explains about human perception.

Regarding the question, if one onion is to be added to the pot of chili to notice the difference, then two onions will be required to add to notice the difference while making twice as much chili with 10 onions.
