This paper will provide experiments to explain Sensory Adaption of the human body. |

Sensory adaptation is the process by which senses become less responsive to particular stimuli. Consider the enjoyment of flowers in a garden at dusk. When the surroundings are brightly lit, the red of a rose or geranium will appear bright against the greens and blues of their leaves. As darkness falls, however, the greens and blues appear brighter, and the red of the flower becomes harder to see. Some people take advantage of this phenomenon by planting “moon gardens,” which are gardens filled with whites, greens, and blues. All of these elements reflect the capability of the visual system.(Editorial Board.2011)

Experiment 1: I placed 3 bowls of water on the counter. The first one is filled with hot, not painfully hot, tap water. The second is lukewarm water (a mixture of hot and cold water). The third is filled with cold tap water. To begin I will place my left hand in the hot and the right hand in the cold for a few seconds, then emerge both hands into the lukewarm water. When I put my hand in the hot water, I sensed a tingling sensation. The hand in the cold water started to get a cool numbing sensation. When I placed them in the lukewarm water, it was like my hands felt “normal” again. The skin also has receptors that respond to tactile pressure. People can feel fine points more easily on some points of the body than others because of the distribu­tion of these receptors, called mechanoreceptors. Ask someone to lightly trace the outline of a small letter of the alphabet on your back and on your hand. You will probably be able to identify the letter on your hand, because you have a large group of mechanoreceptors there. There are not enough mechanoreceptors on the back to be…...

Sensory Adaptation Experiment

...Sensory Adaptation Experiments Task 1 Experiment 1: The sandpaper felt very coarse after rubbing my index fingers on it for the first time. I rated the coarseness at 6. The sandpaper feels less coarse after allowing my fingers to rest for two minutes and I rated the coarseness at 3. Experiment 2: The sugar water became less sweet after swishing it around my mouth for several seconds. The taste of the fresh water surprised me because it tasted salty. Experiment 3: I dipped my right hand in cold water and my left hand in hot water. At first the water in the bowl 1 felt very hot while the water in bowl 2 felt very cold. After a few seconds, the water temperatures felt normal. When I dipped my hands in the lukewarm water, I felt like I had dipped my right hand in hot water and my left hand in cold water. Task 2 I chose three experiments to demonstrate the concept of sensory adaptation. In the first experiment, I rubbed my index fingers over sandpaper for several times and rated its coarseness on a scale of 1-7. I allowed my fingers to rest for two minutes before rubbing them on the same sandpaper for the second time. The first time I rubbed the sandpaper, it felt very coarse, and I rated its coarseness at 6. However, the sandpaper felt less coarse the second time, and I rated its coarseness at 3. In the second experiment, I sipped sugar water and swished it in my mouth for several seconds before disposing it. The sugar water tasted less sweet as I swished it in my......

...All we really can make statements about is that which we, personally, perceive. Whenever there is nothing contradicting our believes, there would be no reason to believe that which we are perceiving to be inaccurate. Otherwise it would be impossible for anything to make a statement about anything and be able to say anything about the accuracy or truth of that statement. Against: 2. All sensory information is eventually judged by individual people. We all look at things subjectively, however hard we want to believe that we are objectively judging a phenomenon. Cognitive and other psychological biases should make us cautious in making statements about the truth values of any claim of accuracy. 3. Communication is never without any noise nor is it exact. Even if claims would accurately represent when they are interpreted in a manner that is deemed to be regular, we cannot a priori assume that these assumptions are inherent to the claims in the manner they are communicated. Statements might be interpreted different by other people or they may be distorted. Contributors to accuracy of sensory data: 1. Repeatability 2. Mathematical tools to assess accuracy and reliability 3. Use of a tested and accepted methodology and toolset that complies to the standards of the scientific community For the matter of nature and nurture, there are a couple of things to say. Through nurture us humans have developed the scientific method which, as we believe, reflects the nature of......

Sensory Adaptation

...Introduction For this paper I will provide definitions for adaptation. It will show how adaptation is evident in the experiments. It will show some of the senses that are present in the human body. Sensory Adaptation “Adaptation is the continued presentation of the same stimulus that causes the receptors to become less sensitive to that particular stimulus; therefore a stronger stimulus is required to activate the receptors”(Davis & Palladino, 2010). With adaptation individuals become acustom to the environment around them. So sensory adaptataion is the decrease appearance of sensitivity to stimulation that results from repeated appearance of the stimulation. The human has five senses: sight, sound, smell, taste, and touch. There will be examples and results from experiments. Examples is the best way to provide information about these senses. The first is the most common adjustment to temperture. You have seen these people that jump in to ice cold water in the winter. These people are members of the polar bear club. When they first jump into the water it is very cold, but after they have been in it for some time their body adjust to the temperture of the water and it is not as cold to them. Another is the sense of smell. You prepare the vegetables and meat for a stew and place them in a slow cooker. During the time you are at work all of these ingredients have been cooking. When you arrive home from work you are greeted by the aroma of the stew. ......

Sensory Adaptation

...Sensory Adaptation American Intercontinental University Sensory Adaptation The three experiments I chose to conduct were Experiment 1, Experiment 2, and Experiment 4. All of the experiments were interesting in their own way. Each experiment had a different outcome but all support adaptation within the experiment. Beginning experiment 1 I purchased a small piece of very coarse sandpaper at the local hardware store. I began by rubbing my index fingers across the sandpaper a few times. The first time I rated the coarseness high on the scale as an 8 and as the experiment progressed I began to rate the coarseness lower and lower on the one to ten scale. Adaptation is evident in this experiment with every rub of my fingers across the sandpaper it felt less abrasive than the first time. My sense of touch adapted to the rough surface with every swipe of my finger. The results of this experiment surprised me my hypothesis prior to conducting the experiments was that my estimate of the level of coarseness would hover around the same number. To set up for experiment 2 I prepared one cup of sugar and water mixed together and another cup of fresh water. I took a sip of the sugar water and swished it around my mouth for awhile then spit it out. Afterwards I took a sip of the fresh water and surprisingly enough it tasted sweet still. I was very surprised that the fresh water tasted sweet after I had spit the sugar water out. I was defiantly surprised with...

Concept of Adaptation

...Megan Dotter Concept of Adaptation Aspects of Psychology SSCI206-1204B-04 Biological Influences IP Week 2 Abstract Teaching a class about the concept of adaptation to a psychology class, experiments could be conducted to help them learn what adaptation is all about. Firsthand knowledge is the best way to teach a large group of people about a concept they may otherwise not fully understand. In this paper you will see and read about some of the findings experienced during this time. Concept of Adaptation This is a new experience for me to teach a class anything so I will begin by giving the information the students should know about adaptation and the examples needed to ensure they understand. After completing that part of the presentation I think it may be beneficial for the students to learn by firsthand experience. There are a few experiments that could be very interesting for them to do on themselves and others. The concept of adaptation is defined as “Diminished sensitivity as a consequence of constant stimulation ("Psych m.d. –," )” or “The tendency of a sensory system to adjust as a result of repeated exposure to a specific type of stimulus such as low levels of light ("Psych m.d. –," ).” An easier way to understand the concept may be to call it sensory adaptation. This explains in the name alone that it will be dealing with the 5 senses we have. Included in these five senses are taste, touch, smell, sight and hearing. I will be touching base on each......

Adaptation and Our Bodies

...Adaptation and Our Bodies Blake Savage Jr. American Intercontinental University Abstract Sensory adaptation is one of many incredible functions in our human bodies. We have 5 major senses that we call upon each and every day. Sight, sound, smell, taste and touch are senses that aid us in our day to day activities. These can also be classified as the proprioceptive, vestibular, tactile and visual systems as well. Each of these senses adapt to the environments around us to help make us more comfortable and to tune out certain annoyances. In the view of evolution, sensory adaptation plays a fairly significant role. Survival of the fittest is usually the test of time and to achieve this trait an animal must adapt to its surroundings and change with it. However, the animal not only needs to change with the environment, it needs to find a way to utilize its senses to better aid it in becoming a top of the food chain animal. Adaptation and Our Bodies When viewing the world we live in we may not readily notice the incredible functions of our bodies on a day to day basis. The fast pace we have grown accustomed to keeps us pre-occupied from really paying attention to the small things that happen around us. Every day we find ourselves being introduced in to an uncomfortable environment. It is the incredible power of our bodies and functions within that adjust to these discomforts and make them more tolerable. This can be defined as Sensory Adaptation. ......

Concept of Adaptation

...Concept of Adaptation Concept of Adaptation Kimberly Johnson Intro to Psychology When we are given the word adaptation we look at the root word which is adapt. It means to make suitable to or to fit. So the word adaptation means the act or process of adapting. I will be conducting 3 experiments in which I will test weather my response is me adapting to the change or if I will not. The three experiments that I will be conducting are first I will test the temperatures of water and see how my sense of touch adapts to the change in temperature. Next I will test my since of taste. I will be tasting sugar water and I will see how my tongue adapts to it verses plain water. Last but not least I will again test my sense of touch with sand paper. After doing each of these three experiments I will be able to clearly define weather or not my senses adapt to change or not. The first experiment is as I stated before me testing my sense of touch. I have the three bowls in front of me the left one with the hot water and the right one with the cold water. The middle bowl has the Luke warm water in it. As I submerged my hands in the right and left bowl, my mind already knows what to expect and even thought my mind knows what is coming, when my hands hit the water it still is a shock with both the hot and cold water. Chills run up both arms and I even shiver a little bit. My hands have to stay here for at least 3 minutes. During this time my left hand is adapting to the hot water but......

Sensory Adaption

...Sensory Adaptation SSCI206-1103A-17 Introduction Sensation is described as the stimulus of the receptors that our brain receives whenever we utilize any of our five senses such as hearing, seeing, smelling, tasting, or touching. Sensation travels through a process called transduction, which converts stimulation such as sight and sound, into electrochemical energy that can be processed by the nervous system (Davis & Palladino, 2010). Sensory adaptation occurs when the "continued presence of that same stimulus results in a loss of sensitivity" (Davis & Palladino, 2010). In order for the brain to continue to experience the stimulus, "a stronger stimulus is needed in order to activate the receptors" (Davis & Palladino, 2010). To test the experience of sensory adaptation, I conducted three experiments, which involved touch and taste. Experiment 1 In the first experiment, I take a piece of sandpaper and rub my index finger over it and rate it on a scale on one to seven, soft to coarse. The first time, the sandpaper felt very coarse, so I would rate it at a seven. Upon waiting a minute, I rubbed my finger over it again. The sandpaper did not feel as coarse the second time, so I would rate it about a four. I waited another minute, and rubbed it again, the sandpaper felt less coarse, I would rate it at about a three. It seemed that over time, my receptors became accustomed to the feeling and therefore, I started to adapt to the coarseness. ......

Sensory Adaptation

...Introduction: Adaptation in sensory evaluation of food refers to the slow drop of sensation (in constant magnitude) after the stimulus has been fully switched on (Lawless & Heyman, 1993). They also added that after a certain time this sensation can completely disappear or in some instances the taste persists that shows a degree of taste adaptation. This idea usually occurs when the perceived taste intensity of one product reduces the other different product. For example, water can taste sour or bitter after a salt adaptation. On the other hand, taste interaction masks the interaction between mixtures of different tastes (Lawless & Heyman, 1993). A solution of sucrose (sweet) and quinine (bitter) will taste less sweet than a pure sucrose solution of the same strength. According to Lawless and Heyman (1993), these sensations are distinguished by taste buds present on the tongue namely fungiform, circumvallate and foliate. They contain 30 to 50 taste receptor cells (TRCs). TRCs protrude hair-like cilia called microvillae to the surface of the taste buds that form the taste pore. This then comes into contact with the saliva. It is believed that flavoursome molecules from food bind to microvillae at the top of the taste cells. After binding, the taste-producing compounds (tastants) transfer sensations to the tongue and beyond by different pathways. For chemicals that produce sweet, umami and bitter tastes they use similar receptors called G- protein coupled receptors......

Adaptation of Sensory Receptors

...Candi Smith-Wiggleswire 2-12-2009 Adaptation of Sensory Receptors Sensory receptors account for our ability to see, hear, taste, and smell, and to sense touch, pain, temperature, and body position. They also provide the unconscious ability of the body to detect changes in blood volume, blood pressure, and the levels of salts, gases, and nutrients in the blood. These specialized cells are exquisitely adapted for the detection of particular physical or chemical events outside the cell. They are connected to nerve cells, or are themselves nerve cells. Many of them are enclosed in sense organs. Others are the endings of nerve fibres that ramify within the skin, the muscles, bones, and joints and the other organs of the body. Yet others are nerve cells within the brain that are sensitive temperature, to dissolved gases, salts, and other substances in the fluid around them. In human beings there are just four basic types of sensory receptor — sensitive to mechanical stimulation, light, chemicals, and temperature — but they vary enormously in their form. The particular kind of stimulus to which they respond is largely determined by the structure of the sense organ around them or by their location in the body. Some animals have receptors sensitive to magnetic fields or to electrical fields. All sensory receptors in the human body operate on the same general principles. Their membranes contain particular protein molecules that are activated and change their shape when......

Sensory Perception

...Understanding Sensory Perception SSCI206-1101A-01 xxxxxxxxxxxxxxx xx xxxxxxxx 20xx AIU Online Abstract In this paper, we address sensory perception relevant to touch perception, temperature perception and taste perception. It contains three experiments, one experiment relevant each perception addressed in this paper. Additionally, we explore the method by which each of the three sensory perceptions is received and interpreted by the human brain. Lastly, we look at the reason why sensory adaptation is of significance relevant an evolutionary perspective. Understanding Sensory Perception Three different experiments were conducted to investigate human sensory adaptation. In the first experiment, a sheet of course grit sandpaper was placed on a table and the test subject gently moved a finger over the sheet of sandpaper 5 times. Using a rating scale of 1 to 7, 1 being a rating of very fine and 7 being a rating of very coarse, the subject rated the level of coarseness as a 7. After 1 minute, the subject again gently moved the same finger over the same sheet of sandpaper 5 times. Using the same rating scale of 1 to 7, the subject rated the level of coarseness as a 4. In the second experiment, three medium sized bowels were placed on a table. The left bowl contained 50% total capacity hot tap water, the center bowl contained 50% capacity lukewarm water and the bowl on the right contained 50% capacity cold tap......

Sensory Adaptation

...Sensory Adaptation Jessica Munden American Intercontinental University Abstract This paper will define and explain the concept of sensory adaptation. Three experiments were conducted to show sensory adaptation. This paper will report the experiments findings by illustrating what was experienced during the experiment. This paper will also discuss how adaptation is important from an evolutionary perspective. Sensory Adaptation Chemical senses, such as taste and smell, and the skin can be affected by sensory adaptation. It is important to understand the systems related to the chemical senses and the skin in order to understand how they can be affected by sensory adaptation. Three experiments were conducted to help explain sensory adaptation, which will appear later. Sensory Adaptation is defined in Words of Wisdom (2011) as “the process by which senses become less responsive to particular stimuli." In other words, when certain stimulus is continued the brain's sensory responses become less responsive. Adaptation affects the sensory systems, which include the five senses vision, taste, smell, hearing, and touch. When a non-smoker walks into a home, in which a person smokes inside, the smell of nicotine will be overwhelming. After spending some time in the home the smell of nicotine will seem to dissipate because one's system will adapt to the smell (Words of Wisdom, 2011). An experiment was conducted to show sensory adaptation to touch. During this experiment, one......
