Two-Point Discrimination Tool

This is similar to one of the objects we had sitting on the "What's this stuff?" table in the beginning of the semester. It's a tool used for a "Two-Point Discrimination" test. The points are placed on the skin and the participant responds to whether or not they feel two points. You would think that everyone would feel two points anywhere, regardless of the distance, but it varies depending on the sensitivity of the area it is placed on. You can put the points very close on your face and feel two spots, but if you put it on your back, you would need much larger of a space to feel the difference
