...Sensory Information Accuracy or Inaccuracy of Sensory Information For thousands of years, humans have asked if we perceive the world accurately through our senses. You sometimes think you hear or see things that are not there. The sense of smell can be overwhelming in a good or bad way. Three reasons I believe in the accuracy of sensory information is one, our senses are the best way for us to function in the world, you need all senses working together and three, it’s hard to disprove what your senses tell you. First, it is believed that sensory information is one of the first areas to fully develop in an infant's brain. We rarely stop to think how important our five senses are in terms of providing us with information about the world. For example, our senses tell us when there is a bug crawling up our leg, if we are going to fall, and whether there is smoke in the room. Without the ability to see, hear, touch, smell, and taste we would live in complete isolation, unable to not only sense, but also to think and learn due to a lack of experience with which to develop ideas. When we discuss sensory integration we add to it the two senses of vestibular (Reponses to movement) and proprioception (body awareness). Each sensory system has its own specific receptor that specializes in optimal responses to a specific type of sensation. Because seeing is so important for our functioning in the world, efforts to understand how perceptions are generated have most...

...almost empty (p.54). Our senses must be present in order to know who we are or who we want to be. Three reasons for believing the accuracy of sensory information are how we perceive things, how we react to them, and what we know of them. Although all senses play equal parts in the affect it has on our brain and our lives in general, sight is one that I would deem most accurate. For example, if you see an accident on a busy highway your first inclination would be to find a different route or calculate how long it will be until you reach your destination, or if you see something dangerous your response is to move away and dial 911. Although sometimes your sight can trick you into seeing things that aren’t really there, majority of the time the information you receive through this sense is accurate. Its like the saying seeing is believing. Taste is another excellent example in accurate sensory information. If we are trying something new for dinner one would tend to determine whether we like it or not within minutes maybe even seconds after hitting our taste buds. Touch is also an example, we are able to determine whether something is hot or cold, rough or soft by just feeling it. This information is always correct because the object is what it is, it does not change. There are many factors that contribute to the accuracy of sensory information. For example, if a person is under the influence of drugs and...

...Three reasons I believing in the accuracy of sensory information are as followed. 1. Whenever you touch something hot or cold, the sense of touch and feelings detects it and sends a message to the brain, and in response you react and remove your hand from that hot or cold object that you have touched. 2. Your sense of sight helps you see and thus respond accordingly. When you see something dangerous you response by moving away from it and similarly when you see some vehicle coming your way, you wait to cross the busy street. 3. Sense of taste helps you to decide whether the food is eatable or not. Sensory organs in the tongue helps us to decide what we like and what we do not when it comes to tasting food. Three factors contributing to the accuracy of sensory data. 1. Your sense of touch is found all over your body. This is because your sense of touch originates in the bottom layer of your skin called the dermis. The dermis is filled with many tiny nerve endings which give you information about the things with which your body comes in contact. They do this by carrying the information to the spinal cord, which sends messages to the brain where the feeling are registered. The nerve endings in your skin can tell you if something is hot or cold. They can also feel if something is hurting you. Your body has about twenty different types of nerve endings that all send messages to your brain. However, the most common receptors are heat, cold,...

...Sensory Perceptions Provide at least three (3) reasons for believing in the accuracy or inaccuracy of sensory information. (Kirby and Goodpaster 2007) said it all “There is nothing in the mind unless it first senses.” When we are first born our five senses are just starting to develop from the first taste of milk to hearing people speak, to even the touch of our mothers hand while feeding. At the time a baby is born they are not aware food will be important for them to survive or to be able to distinguish between hot or cold. They will hear words and not understand, hear sounds around them and will not know what they are, until they are taught, they do not know at this time how important their senses will be to them later in life and how their senses will interact with their brain. Now as we grow into adults our senses have become interwoven with the way we think and use our minds. We use our eyes to read a book or even recipes to cook. When we listen to music, hear the birds chirp, our children laughing we are using our ears to hear these wonderful sounds. Our ears can also hear sounds that we do not want to hear as well. We have to think when we use our hands to fix a car, play a guitar, and we even have to think what the heck we are doing jumping out of a good airplane, when you go airborne in the military, and in this case you are thinking but using probably all of your senses except for smell. Now it is true that “there is nothing in our mind unless...

...This scene illustrates how Taylor is angry about the baby and doesn’t want anything to do with Nate. (“‘I’m pregnant’… My voice escaping my throat sharply didn’t belong to me; it was that of an animal… I wanted to scream the ugly truth in his face but I couldn’t raise my voice above a shuddering whisper…”) The author uses sensory detail in this scene to show how furious Taylor really is and how mixed her emotions are. They fight over the baby, Taylor saying it’s her baby and Nate saying it’s both of theirs. This contributes to the theme by showing how discouraged and furious Taylor is and how she doesn’t let it completely get her down. The final example is when Taylor starts to lose her grip on reality. This scene explains how Taylor is practically walking into insanity. “ ‘Are you lost?’ In my mind, yes, I was nearly gone. The thought of passing into insanity crept up in my head with clawing, pale arms, the lifeless face turned up in agony. The flashbacks would kill me if the house didn’t. I was lost” (Lindt 149)The author crafts interesting word choice into this...

...Sensory imagery is an incredibly important aspect of any well written novel. It is what allows the reader to experience what is going on in the story with more than just an intellectual understanding of the material. Without these sensory details it becomes easy for a reader to dismiss or misunderstand what a character is going through at any point in the story. An excellent example of both sensory description and imagery is when Laila’s home is destroyed in a rocket attack. The beginning of the scene is of Laila helping bring her family’s belongings out of the house. While on the surface this sounds extraordinarily dull the choice of phrasing and inclusion of sensory details instead creates an experience in the readers mind that is worth having. “Laila kept shuffling between the house and the yard, back and forth.” (Hosseini 192). Hosseini could have just as easily told the readers that she was moving stuff out of the house over and over, instead one can see how she is moving thus enhancing the readers enjoyment of an otherwise rather drab scene. These sensory descriptions increase in intensity and depth as the passage continues. Laila is summoned by Mammy and Hosseni paints a picture with words, “The sun bright and warm, caught in her greying hair, shown on her thin drawn face. Mammy was wearing the same cobalt blue dress… a youthful dress meant for a young woman, but, for a moment Mammy looked to Laila like an old woman with stringy arms and sunken temples and slow eyes...

...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 cooking...

...Sensory Perception PHI 210 Strayer University Sensory Perception PHI 210 The sensory system is a part of the nervous system. It is responsible for processing our sensory information, and it is the way in which we make contact in our everyday lives through our five senses – sight, touch, hearing, smell and taste. (IML Training, 2012) Our sensory receptors allow us to pick up information – ears, eyes, nostrils, tongue and skin. All senses evolve to collect their distinct type of information about our environment and to inform us of our status within it. (Goldstein, 2009) The brain is deeply connected to sensory data creating memories. Thinking and memory go hand in hand. When life senses filter our brain, our senses link to our brain as we think. Memory allows us to push forward and experience the future. How and what we think has a lot to do with our ability to remember. Poor or distorted memory stifles thought and can make it difficult. No one has a perfect memory; hearing and listening to recollections from others which may create accurate versions of our life experiences is advised. At times of sickness or fatigue, our perceptions can very well deceive our brain. (Goodpaster, 2007) In describing perception, it is the interpretation of what is sensed. Transmissions from physical events to the retina can be interpreted in the form of patterns, colors and shapes. These same physical events filter through the ear and can be interpreted as voices, music...

...feeling that a person has when speaking. Also the look of the way the environment is can make a person assume a specific way about the area. The way something smells can make a person decide, without any other information, whether or not they like a product or service. The way the senses guide people in their decision making can either make them have conscious decisions or it can make them close-minded to the area around them. The three main functions of sensory information are: The sensory nerves gather information from the environment then sends that info to the spinal cord, which then speed the message to the brain. The brain then makes sense of that message and fires off a response. Motor neurons deliver the instructions from the brain to the rest of your body. The spinal cord, made of a bundle of nerves running up and down the spine, is similar to a superhighway, speeding messages to and from the brain at every second (The Brain, 2005). Information is passed from the sensory memory into short-term memory via the process of attention (the cognitive process of selectively concentrating on one aspect of the environment while ignoring other things), which effectively filters the stimuli to only those which are of interest at any given time (Sensory Memory). Sensory memory is an ultra-short-term memory and decays or degrades very quickly, typically in the region of 200 - 500 milliseconds (1/5 - 1/2 second) after the perception of an item, and certainly less than a second (although...

...Introduction Psychologists studying perceptual development tend to make a distinction between sensation - "the functioning of our sensory system", and perception - "the interpretation of those sensations" (Foley & Matlin, 2010, p. 2). Perceptual development provides the foundation for interpreting the events of the world around us. Stimuli from the environment that evoke sensory experiences of hearing, seeing, and touching promote brain growth and development. Our sensory systems do indeed change over time, just like the rest of our body. At birth our senses are not completely developed giving us an incomplete view of the world. As we age, our senses will decline leaving us with less of a connection with the world. The path and nature of the development of our senses are important for several reasons. Understanding development helps the medical field intervene in problems to help people of all ages have more normal sensory systems. Understanding development also yields important insight into the basic operations of our sensory systems. Seeing how they change gives researchers peaks into the nature of their general operation. In perceptual development, many focus area does exist, but for the purpose of this paper, emphasis will be placed on discussing the significance of nature vs. nurture to perceptual development in infants, as well as discuss other sensation and perception concepts like visual abilities – acuity and eye movements. Nature vs. Nurture Nature and Nurture in...

...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 water...

...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 rubbed...

...However, recent research has made it more difficult to draw a clear line between sensation and perception. That research shows that the process of interpreting sensations begins in the sense organs themselves and continues into the brain. Even previous experience can shape what you sense, causing you not to notice. Sensory Systems The senses gather information about the world by detecting various forms of energy, such as sound, light, heat, and physical pressure. For example, the eyes detect light energy, the ears detect the of sound , and the skin detects the energy of heat and pressure. Humans depend primarily on vision, hearing, and the skin senses to gain information about the world: they depend less than other animals on smell and taste. There are also senses that provide information to the brain from the rest of the body. All of these senses must detect stimuli, encode them into neural activity, and transfer this coded information to the brain. Steps in Sensation At each step, sensory information is processed in some way: the information that arrives at one point in the system is not the same as to the information that goes to the next step. In some sensory systems, the first step in sensation involves accessory structures, which modify the stimulus. The lens of the eye is an accessory structure that changes incoming light by focusing it; the outer part of the ear...
