Sensory Problems

Situation A: You are a home health care nurse. One of your patients is Frank, a 75 year old man that smoked most his life and now lives alone. 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. In conductive hearing loss the tympanic membrane perforated or the small bones of the middle ear is damaged, usually because infection of middle ear. While sensory hearing loss is because of nerve or cochlear damaged, usually because of toxicity or hereditary.

2. Describe how the Weber & Rinne tests work to differentiate these two disorders. (2pts)

These are two testes used to differentiate between conductive and sensory hearing lost.

Situation D: A rare (and unreal)…...

...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......

...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 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 Victoria Shelton Strayer University PHI 210 Joel Goldstein January 25, 2013 Sensory Perceptions Reasons for believing in the accuracy of sensory information What is sensory perception? Sensory perception is the events or occurrences in the environment a person takes in, processes and understands through their five senses. Three reasons for believing in the accuracy or inaccuracy of sensory information is perception, interpretation, and knowledge. In the words of Jacques Barzun, “In ordinary speech the words perception and sensation tend to be used interchangeably, but the psychologist distinguishes. Sensations are the items of consciousness—a color, a weight, a texture—that we tend to think of as simple and single. Perceptions are complex affairs that embrace sensation together with other, associated or revived contents of the mind, including emotions (Barzun, 1907).” Perception is the organization, identification and interpretation of sensory information in order to represent and understand the environment (2003). This is as a result of organizing and interpreting information that is gained from our five senses which we use on a daily basis. Our senses can be helpful to us in many ways by providing our brains with the right information, or harmful by making our minds play tricks on us. The accuracy of this information that is taken in varies because of many different reasons. Sensory information is gained as first-hand......

Sensory Perception

...what we want or expect to see regardless of reality. A common illusion, the vanishing ball, clearly shows this to be true. The magician will throw the ball into the air repeatedly. But the last time he only pretends to throw the ball, instead concealing it in his hand. Even thought this was done in plain sight people expect to see the ball go up in the air and therefore believe it did. This is an example of how expectation can affect our sensory perception. (magic perception) “Our senses do not operate effectively when we are sick, drowsy, or tired…” (book) These are a few examples of factors that contribute to the inaccuracy of our senses. One factor in particular is sleep, or the lack of. Over our life time we will spend approximately a third of our time sleeping. (book) Some studies say that people who sleep six or less hours a night may experience the equivalent of two nights of total sleep deprivation. (book) Sleep deprivation can negatively affect our “mood, motivation, memory, decision making, concentration, problem solving, and logical thinking.” (book) When we are sleep deprived what our senses perceive may be inaccurate, and what is accurately perceived may be misinterpreted. A second factor that contributes to the inaccuracy of our senses is food and nutrition. Our bodies are like machines and machines that are not well cared for will not perform at their best. Our bodies not only require proper amounts of sleep but the proper fuel as well. ......

...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......

Provide at least three (3) reasons for believing in the accuracy or inaccuracy of sensory information. Sensory perception can be defined as receipt through the power of physical awareness, hearing, seeing, smelling, tasting, touching, and comprehensible upon transfer to reason. I believe in the accuracy of sensory information but our sensory perception can be misleading. Sensory perception is a part of our daily life and everyone approaches and perceives things differently. This old phrase or saying has been stated for centuries, "we can't always believe what we see." This falls into the first cause which is an interpretation. Everyone interpret things differently, even though we could be watching, feeling, and hearing, the same event or occurrence. This leads right into my second point which is sight perception. The senses of sight teach the mind to see everything that is visual directly in front of us and to detect movement in our peripheral vision. With that being said, we have taught ourselves that what is recognize as one thing may not be identified as the same thing by another person. One of the most notable disagreements would be colors. Due to the fact that there are so many......

... Sensory Perceptions Rodney Edwards Professor Andrew N. Carpenter PHI 210 4/27/2014 Provide at least three reasons for believing in the accuracy or inaccuracy of sensory information. The three main reasons for believing in the accuracy or inaccuracy of sensory information would be Perception, interpretation, and knowledge. Without ours senses we are nothing. We would not be able to Touch taste, feel, or smell. They are who we are. 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. http://www.studymode.com/subjects/. What we are experiencing at any given moment or our experience in life is what the inaccuracy of sensory information is based on. Knowledge is the key for believing in the accuracy or inaccuracy of sensory information. Knowledge informs decisions about what to believe and how to act. It also aides in making good decisions. More importantly, knowledge is the basis for right and wrong. Identify and describe at least three factors contributing to the accuracy of sensory data. One factor contributing to the accuracy of sensory data would be smell. Our sense of smell is very important. It can send us messages. If there is a fire you could smell it ahead of time and get others to safety. Your sense of smell could tell you messages about your own body if your body did not smell so pleasant, so that you can correct the problem. It can also aid you in......

...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......

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...
