according to weber's law, the jnd for stimulus magnitude is: a) a constant proportion of the magnitude of the original stimulus. b) proportional to half the logarithm of the difference between the original stimulus and the comparison stimulus. c) the magnitude of the original stimulus raised to the power 3.14. d) the average of the responses obtained through the method of magnitude estimation.



Answer :

According to Weber's law, the just-noticeable difference for stimulus magnitude is a constant proportion of the magnitude of the original stimulus. The Option A is correct.

What is Weber's Law about?

Weber's law tells about noticeable difference (or JND) between two stimuli is a constant proportion of the intensity of the original stimulus. In other words, when one light bulb is twice as bright as another light bulb, it will take twice as much increase in the intensity of the second light bulb for the two to appear equally bright.

It is often focused on stimulus, change and how likely someone is to notice or react to the change. For example, when someone is much more likely to react to quiet commercial that suddenly doubles in volume than a commercial that only slightly increases in volume.

In conclusion, the law postulates that strength and intensity needed to identify changes in a stimulant correlates to the magnitude of the stimulant.
