In the experiment involving sandpaper, I rubbed the index finger on the sand paper many times and rated the coarseness as directed. After resting for two minutes, I rubbed the index finger for the second time on the same sandpaper. After conducting the experiment for the first time, the sand paper felt very rough. The rating was at six. The second time, the sandpaper was not as course as compared to the first time, the rating was at three.
The experiment involving sugar concentration followed next. I began by sipping the sugar water and swishing it in the mouth for some time before disposing it. The taste of the sugar water was less sweet as I continued swishing it in the mouth. Immediately after disposing it, I tasted fresh water that tasted salty.
The third experiment involved water at different temperatures. As instructed, I filled three bowls with water at different temperature. The first bowl contained hot water, the second cold water and the third contained a mixture of hot and cold water (Lukewarm water). I dipped the right hand in the bowl containing cold water and my left hand in the one containing hot water. I rested the hands in the bowls for around three minutes. During the first minutes, the temperatures felt extreme but after sometime, it felt normal. Immediately after withdrawing the hands from the bowls, I dipped both hands in the third bowl containing the lukewarm water. The temperature felt as if it was reversed such that the left hand was dipped in cold water and the right in hot water.
Sensory adaptation is defined as the characteristics of the human senses that make them to decrease the responsiveness to persistent or continuous stimuli. Sensory receptors better respond to varying stimulation than constant level of stimulation. It is unintentional and can only be reversed by changing or eliminating the stimuli. Nerve cells firing
