Psychology Experiments/Biological Influences Essay

In this experiment, we aim to provide an understanding about the concepts of adjustment through a series of tests. This involves using our contrasting senses to perceive changes in an environment, and how well be able to adapt to these changes. In the first experiment, the sense that we are divergence to use is the sense of seek. Through this test, well determine how we adapt to changes in what we taste or basic onlyy what we eat. By mixing sugar into body of water, we create a sweet substance which were going to use for the taste test. We also need fresh water in order to tell any differences afterwards. What I did was to piss a sip of sugar water and let it stay in my mouth for some time, until it tastes little sweet. It took several seconds until it tasted slight sweet, and afterwards I took a sip from the cup containing fresh water. The surprising affair was that the fresh water tasted doesnt have any taste in it at all. I screw water supposedly has no taste, but with t he experiment, it tasted stale. In the next test, the sense that will be use is our tactile sense, mainly the skins perception of temperature. Through this test, well determine how we adopt to the changes of temperature in our environment. We conjure three bowls with knap water of varying temperature. One is hot (but not painfully so), another(prenominal) is very cold, and the other is a compartmentalisation of the hot and cold tap water. What I did was to submerge my leftover hand in the hot tap water and my right hand on the cold tap water. I let it stay there for three minutes, and afterwards I placed both my manpower in the bowl containing the mixture of hot and cold tap water. I took not of what I snarl in the experiment. Upon placing my both my work force in the mixture of water, I noticed that my left (which was previously sink on the hot one) felt cold until it slowly changes back to the temperature of the water mixture. homogeneous goes for my right hand, which f elt warm when I submerged it in the mixture until it slowly changed back to the temperature of the water mixture. The skins receptor was not able to perceive any changes in the temperature in the water. The final test was again on the tactile sense, wherein we have to rile our index finger into a sand paper and lay out its coarseness from 1 to 7, where 1 is very soft, and 7 is very coarse. When I rubbed my index finger to the sandpaper, my sign rating was that its 7, since I felt that it was very coarse to touch. When I rubbed my index finger on the sand paper for a second time, it felt a little different. Its as if it scattered its coarseness a bit. I gave it a rating of 5. Basing on the experiment, adaptation can be specify as the loss of sensitivity of a receptor due to prolonged stimulation of it. Because of this, it would require a stronger stimulus in order to further activate it. Adaptation is defined as a lordly characteristic of an organism that has been favoured by natural selection, since they are able to live successfully in an environment. This enables sustenance organisms to cope with environmental stresses and pressures, something which could result from the body structure, the organisms behaviour, or its physiology (EPA.gov, 2007). Adaptation is evident in each of the results of the experiments. On the first experiment on water sugar, there was a sour aftertaste when I sipped fresh water. This could be because sour taste wastes the sweet taste so when we sipped sugar water and swished it all over our mouth, we psychologically perceive that there is a sour taste in order to neutralize the sweet taste in our mouths. On the second experiment on waters with different temperatures, we get it on adaptation by being able to keep a constant body temperature. When we have our hands submerged in both hot and cold water and then submerge it to a mixture of cold and hot water. Our body tends to maintain a constant body temperature, so when it was from the hot water and then submerging it to the mixture, it would surely feel cold at first until we get used to the temperature. Same goes with the cold water, wherein when we submerge it to the mixture it would feel warm until it gets used to the temperature of the mixture. On the third experiment, we experience adaptation at the tactile sensory level, wherein we tend to get used to the feel of the coarse sand paper, that when we rub at it again, it feels a little less coarse. This is adaptation in a sense that our body or our perception of the coarse texture of the sand paper is gradually being changed to a state wherein we wont feel uncomfortable in rubbing against it. As we feel that it is a little less coarse, then we are able to cope with its coarse texture. We can associate this with the theory of adaptation by Lamarck, where organisms inherit the traits which are necessary for them to survive. Those who inherit this trait are able to continue to live, while those who pre sumet tend to perish. Because of this, the organisms who continue to exist are the ones who were able to get traits which would enable them to adapt to the terra firma they live in. In an evolutionary perspective, adaptation is really important because those who are able to adapt will be the ones to survive and continue to exist. This will result to organism who posses traits which are important for them to live in their environment. As the time continues to change the surroundings, only those who are able to cope with these changes will be the ones left to live. Those who are not fit enough to adapt to these changes will surely perish. Those who successfully adapts would lead to the mankind of a better species.ReferenceEPA.gov. (2007). Adaptation.
