Suppose we did a demonstration in class with a backpack, tennis balls and two student assistants. As tennis balls were added the student perceived a change in weight of the backpack. This demonstration would provide an example of the which is the minimum intensity of sensory stimulation needs to change before the sensation is detected 50 percent of the time.

Suppose we did a demonstration in class with a backpack, tennis balls and two student assistants. As tennis balls were added the student perceived a change in weight of the backpack. This demonstration would provide an example of the difference Threshold which is the minimum intensity of sensory stimulation needs to change before the sensation is detected 50 percent of the time.
