Sensory adaption is an occurrence where sensory neurons become less sensitive to stimulation. When you have sensory receptors that change their sensitivity this is also a cause of sensory adaption. A lot of times we become use to things around us like normal sounds, smells and people we see every day.

I could feel the bumps on my fingertip as my finger went across the sandpaper which made me ignored about the sensation. It also felt as though my finger was still on the sandpaper after I had it off of it. After waiting two minutes I then re did the same experiment by rubbing the same finger across the sandpaper again. At this time my brain was saying the sensation was the same but my finger was use to the coarseness so it did not feel as bad this time. So I then rated the second time at a 3. Although this time when I released my finger the sensation stayed longer.

The next experiment I chose was experiment 2. In this experiment I had a cup with sugar water and another with fresh water. As I swished the sugar water around in my mouth it felt as though the sugar water was intensifying.
