Step 1

In this case, the original stimulus is the number of onions in the chili, and the change in stimulus is the number of onions you need to add to notice a difference. So, we can write this ratio as: \[\frac{1}{5} = \frac{x}{10}\] Show more…

Key Concepts

Proportional Change

A concept that emphasizes that changes in a stimulus are perceived based on a ratio to the original stimulus, so when the baseline amount increases, the magnitude of change needed to notice a difference increases accordingly.

Weber's Law

A principle in psychophysics that states the just noticeable difference (JND) between two stimuli is a constant proportion of the original stimulus level, meaning that any perceptible change is relative to the initial value rather than being an absolute amount.

Just Noticeable Difference

Also known as the differential threshold, this concept refers to the smallest change in a stimulus that can be detected by a sensory system, which according to Weber’s Law, scales proportionally with the intensity of the stimulus.
