Answer:
Difference threshold
Explanation:
The difference threshold is the minimum amount of change that a person needs to notice the change fifty percent. This phenomenon is referred to as all areas like perception, hearing, touch, sound, taste, and smell. These all senses are to be met before any changes in the stimuli are to be sensed.
For example, if we give a marshmallow and would again give on more then you would probably notice the differences between the stimulus threshold.
