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.
Experiment 2
For the second experiment, I filled three bowls with water of varying temperatures. The first bowl was hot water, the second bowl, lukewarm water, and the third bowl was cold water. I then placed one hand in the hot water and one hand in the cold water and left them there for three minutes. Afterwards, I placed both hands in the bowl filled with both hot and cold. Upon doing this,…...

...Assignment 1: Sensory Perceptions Nicole Brock PHI 210 Renee Pistone 10/21/2012 “The brain, a complex structure, allows a human being to perceive and react to their environment, contemplate "the big questions," and experience a myriad of emotions. The brain controls the body and maintains the delicate internal balance needed to sustain life” (Smith, 2010). If fortunate enough, we humans all have five senses: vision, hearing, taste, touch, and smell. All of these senses that we have, work together to give us a conscientious picture of the world and where we belong in it. The statement, “There is nothing in the mind unless it is first in the senses” (Kirby & Goodpaster, pg. 54), means, that our brain would be empty without our senses. Our senses consolidate to make us understand who we are, where we are, and what is happening around us. Because our brain feeds and processes information about our five senses, we put meaning to our sensory experiences, thus, we are able to respond and behave accordingly. We rely on accurate observations. Our senses prove its accuracy on a daily basis and “act as our lenses, amplifiers, particle detectors, and pressure and heat gauges” (Kirby & Goodpaster, pg. 54). Our vision allows us to be aware so we can stop at red lights, wait for cars to pass, and know when it is safe to walk across the street. Hearing is another powerful sense that we use to listen to words, is crucial in communication, and is interactive with our......

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. ......

Adaption

...Kent Van Cleave My Experience with Adaption The nervous system along with the brain is always adapting to match the surrounding environment. This paper will give you my experience for the experiments I conducted. My first experience is with rubbing my fingers with the sandpaper. After gently rubbing my fingertips with the sandpaper, on a scale of one to seven, I would rate it a five because it made my fingertips rough and they started tingling all the way up my arm. After waiting a few minutes, I tried it again and it wasn’t as shocking as the first time I did it. I believe my mind had already prepared me for what was about to happen. Also my fingertips felt smoother. My second experiment was to taste sugar water. After taking a few sips and spitting it out, there was a sweet taste lingering in my mouth. When I drank the cold fresh water, there was a bland or nasty taste. It almost caught me off guard because it gave me lockjaw. My third and last experiment was placing my hands in hot, cold and lukewarm water. After soaking my hands, one in cold and one in hot water for a short period of time, I then placed my hands in a bowl of lukewarm water. I felt tingling in my hands as if they were numb. After letting them soak for a little while longer, my hands gradually felt back to normal. Sensory adaption is when the body adjusts your senses to a particular smell, feeling, or taste. I feel the concept of sensory adaption is that the body is evolving to fit......

Sensory Perceptions

...Sensory Perceptions Patsy M. Mendoza Professor Dena Hurst Critical Thinking 210 April 18, 2013 Provide at least three reasons for believing in the accuracy or inaccuracy of sensory information. Senses are reliable tools but at times they often fail to transmit accurate data to the brain. When a person is ill, drowsy, or exhausted the senses tend to be less efficient. For infants, sensing will usually occur before a thought but for adults, it occurs simultaneously while engaging in thoughts. Adults usually depend on their senses in almost everything they do from thinking before doing something to not thinking and doing things that come naturally to them. Perception comes between simple sensation and complex cognitive behavior (human nervous system, 2013). Perception is so automatic to individuals that they hardly realize that what they are seeing and hearing is only an interpretation (human nervous system, 2013). Three reasons for believing in the accuracy or inaccuracy of sensory information is discernment, elucidation, and awareness. Discernment is the ability to judge well (The Free Dictionary, 2013). Discernment generates one’s experience of the world around them and allows them to respond inside his or her surroundings. Elucidation is a communication method intended to clarify or explain that serves to make the explanation clear (The Free Dictionary, 2013). Finally awareness; awareness is defined as having knowledge and cognitive response to a......

Most of our thinking is sensory interactive, meaning, our brain is what surrounds our senses. This sensing-thinking connection is so closely interrelated that our thinking often begins in our senses, progresses through additional sensory input, and shapes itself to our sensing habits, that is to say, our thinking can introduce a particular form to the way we sense. SENSORY PERCEPTIONS 3 The power of our senses act as our lenses, amplifiers, particle detectors, and pressure and heat gauges. These sensor are very precise and are need in every aspect of human life.

...| Sensory Adaptation | Psychology Unit 2 IP | | Pamela Bradford 21571629 | 8/4/2013 | 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......

You notice that he is losing weight. When asked about eating, he says that "food just doesn't taste right any more". Explain what has happened to Frank's senses to cause this problem. (2 pts) Since he smoked all his life, tong cancer might be the main reason for losing taste sensation. Situation B: Debbie is a 40 year old slightly overweight woman with Type II diabetes. She has high blood pressure and chronic high blood sugar levels. Why did her primary care physician insist that Debbie visit an eye doctor even though Debbie has never worn glasses? (list at least 2 different disorders that may be involved). (2 pts) People effected by diabetes and high blood pressure are at high risk of developing diabetic retinal lesions and hypertensive retinal lesions (pathological damage). These two conditions can seriously affect the sight and might lead to blindness. Situation C: Ron is a 47 year old Army veteran with a hearing impairment. Consider the pathways of hearing and answer the following questions: 1. What are the two major categories of hearing loss? (include the structure impaired in each case) (2 pts) The two types of hearing loess are conductive and sensory.

The Concept of Adaption

...The Concept of Adaption JoAnn Wade American InterContinental University Online December 9, 2013 The Concept of Adaption The first experiment that was performed was rubbing a finger gently over a piece of very coarse sandpaper a few times and rates its coarseness on a scale from 1 being very soft to 7 being very coarse. Then after a minute or two, rub the same finger over the paper and again rate its coarseness. The first time the perception rating was a 6 or a 7, very coarse. After a minute or two the same finger was rubbed along the sandpaper again. This time the rating was a 3 or a 4 softer than the first time. The reason for the rating scale to have lowered was that the finger had adapted to the coarseness of the sandpaper. It still felt the roughness of the paper but it was not as rough the second time. The second experiment was to prepare one cup of sugar water and one with fresh water. Take a sip of the sugar water and swish it around in your mouth for several seconds without swallowing it. Gradually, it should taste less sweet, dispose of the water. Taste the cup containing fresh water. With the sugar water your mouth became adapted to the taste of the sweetness. The second taste of the fresh water was a surprise because your mouth had become adapted to the sugar water and the fresh water was a sudden, different change. The third experiment was fill three medium-sized bowls as follows: bowl 1 with very hot tap water; bowl 2 with very cold tap water; bowl 3...

Sensory Perception

...Assignment 1 Sensory Perceptions Ms. Angelia L. McNair Strayer University, Christiana Professor Dr. Chelsea Snelgrove Critical Thinking – PHI 210 January 23, 2014 There are five senses they are taste, sound, sight, smell, and touch. As humans, we should believe in the accuracy of sensory information because when we were first born we have the ability of sense. Five senses are important in terms of providing us with information about the world and our environments. Perception involves the selection, organization, and interpretation of sensory information. Our sensing-thinking connection is closely interrelated that our thinking often begins in our senses, progresses through additional sensory input, and shapes itself to our sensing habits; conversely, thinking can shape the way sense. For these explanations, we as humans should believe the accuracy of our sensory information as it is received. A great thinker, John Locke says that our brain is a blank slate at birth, or is it innate with ideas? John Locke agrees with Aristotle and calls the mind a tabula rasa (blank slate) that our senses and experiences write upon. Other philosophers (Plato), psychologists (Jung) and linguists (Chomsky) agree at least partially with this concept. They do not believe that the mind (or brain) start empty. I tend to agree the thoughts of Plato, Jung, and Chomsky that we have innate, or inborn, ideas or structures in our mind. The statement “There is nothing in the mind......

Sensory Perceptions

...Sensory Perceptions Critical Thinking-PHI 210 April 19, 2013 The interpretation of sensory data gives us a perceptual view of our world. I say our world because as humans we all gather information by using sensory perceptions. Sensory perceptions are the conscious recognition and interpretation of sensory stimuli that serve as a basis for understanding, learning, knowing or for motivating a particular action or reaction. Humans have five senses: touch, feel, taste, see, and hearing. These senses are used to perceive sensory information. Three reasons for believing in the accuracy or inaccuracy of sensory information is perception, interpretation, and knowledge. Perception is our sensory experience of the world around us and involves both the recognition of environmental stimuli and actions in response to these stimuli (Bagley, 2004). Through the perceptual process, we use or senses to acquire information about the surrounding environment or situation. Humans use our attitudes and / or understanding of our observations to react within our environment. Interpretation is a communication process, designed to reveal meanings, Interpretation is how we perceive certain situations through our own thoughts and beliefs. It’s a conception of another’s behavior, People have different interpretation of life and how they view certain things. What may be true to you may not be true to me. Knowledge is a familiarity with someone or something, which can include facts, information,......

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......

Rita Pimenta de Devotto “The process of collaborative problem solving needs to be better understood so that it can be applied more insightfully.” Kirton, 2003. SUMMARY This article aims to introduce Adaption-Innovation Theory (A-I) and the Kirton AdaptionInnovation Inventory (KAI) to readers not familiar with this subject. It will explain the origins of both, the theory and the psychometric instrument and give an overview of the core concepts of the theory. It will also discuss the contributions of A-I and KAI to management practice and explore its current use in organizations for improving team’s problem solving. Introduction In a world of complex and diverse problems, where change is constant, which is better: Adaption or Innovation? Following the current trend we probably should choose innovation betting it will solve most of the problems. However, accordingly to Kirton (2003), which is better depends on the problem-solving context. The current trend underplays adaption and ignores all creative solutions that come from “doing things better” (Kirton, 2003 p.55). Adaption-Innovation theory (A-I from now on) proposes that a diversity of problem solvers (“more adaptive” to “more innovative”) is required to solve a diversity of problems. Not only innovators are creative and capable of bring......

Sensory Perceptions

...Sensory Perceptions Strayer University Abstract As Human beings we are blessed to have five senses. These senses are sight, smell, touch, taste, and hearing. These senses make “normal” life manageable for us. All five are equally as important as the next. However it is not impossible to live without one or two of them. Sometimes losing one our senses can enhance the rest. There are three reasons to believe that our senses are fallible. Seeing should not always be believing. Once we realize that our senses can be fooled, then we can begin to adjust to surface appearance and personal distortions. Sensory Perceptions Sometimes our senses can be accurate, and sometimes they can be inaccurate. The accuracy of our senses enables us to do things in our everyday lives. We are able to make judgments on what we are doing or will be doing next given our surroundings. Our senses act as our lenses, amplifiers, particle detectors, and pressure and heat gauges. These sensors are acutely sensitive. Our hearing reacts to a sound vibration at a frequency as high as 20,000 cycles per second and to a multitude of timbres that allow us to recognize different human voices. Our sight can detect a candle flame on a dark, clear night 20 miles away. Our sense of smell can detect a single molecule of bacon or coffee out of five billion molecules. Our senses feed our brain as much as our body. Sometimes our senses can be deceived. Our senses do not always deliver accurate data to our brain...

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......
