Experiments and Adaption
July 30, 2012
This paper is explaining five experiments; the process and results. It talks about sensory adaptation and how adaptation is evident in each of the experimental results. It also provides a comprehensive description of the sensory systems in the experiments that I performed.
Before starting the four experiments, I had to remember that I had to keep in mind that there are five major senses that our bodies use; taste, smell, seeing and hearing. I also felt that it was extremely important to get a general understanding of what sensory adaptation means. Sensory adaptation is the process by which senses become less responsive to particular stimuli. Therefore, to activate the receptors a stronger stimulus is required and individual’s body receptors will to one type of stimulus at a time (Hersh, 2011). In my first experiment, I rubbed my index finger gently over a piece of very coarse sandpaper a few times and then rated its coarseness. Then I waited a few minutes and rubbed the same finger over the paper and rated the coarseness again. On a scale from 1 to 7, 1 being very soft and 7 being very course, I would have to say that it went from a 7 to a 3. In this particular experiment, I use the sense of touch with sensory adaptation. As I rubbed my finger over the sandpaper the first time, my finger felt the coarseness and my brain received the signal that it was. The second time I rubbed my finger over the sandpaper, my receptors had already adapted to the stimulus and the coarseness was less than before. In experiment 2, I filled two cups up with water, one with sugar and other with fresh water. First, I took a sip of the sugar water and swished it around in my mouth for about 60 seconds and then spit it out. Then I took a sip of the fresh water, I would have to say that the taste of the fresh water...
