The senses: Taste, touch, sight, hearing and smell. Everything we know is based on our perception of our senses and our knowledge of the world. Everything we know of perceptually in our brain’s memory bank is built upon the senses. Our senses pick up information and send it to our brain to be processed into something tangible. We use our senses to prove what we are told and we unconsciously depend upon our senses to function. Someone tells us a train is coming and it is near; we immediately want proof of it. The first instinct we have is to look for it and if we don’t see it we listen for it. If we cannot see or hear it then more than likely we are probably not going to believe that the train is near and dismiss the person as being misinformed. Our senses help us to make ‘sound” judgments as to whether we believe in something, if we like or dislike something, and if we trust or fear something. Without our senses we could not function.
Businesses use sensory analysis, a technique to test or analyze our senses for their marketing. A restaurant uses sensory analysis to find out if their products are feasible to market by analyzing the effect a food product has upon their clients. The International Organization for Standardization has set procedures for sensory analysis “to conduct sensory evaluations under constant, controlled conditions with a minimum of distractions, to reduce the effect that psychological factors and physical conditions can have on human judgment” (International Organization of Standards, 2007). Sensory analysis will gather information on the flavor, taste, texture, appearance and aroma and then use that information to develop their product, compare it to the competition, and a use it as a quality benchmark to ensure it meets certain specifications. Companies are willing to pay for this research because it allows them to know if their product is something their clientele will potentially buy and enjoy.
We use our senses for our safety. Our safety depends partly on our senses which then trigger an unconscious reaction. That reaction is our instincts. Trusting our instincts based on our sensory perceptions is hard to describe. “Scientists continue to prove the importance of believing in what we call our instincts but in fact are simply the natural gifts of rapid cognition and unconscious (subconscious) sense recognition.” (Smith, 2009) Smith talks in his article about officer safety but it applies to everyone. Sometimes our senses pick up clues to our environment and we unconsciously process that information and act upon it. Sometimes we see something and although it does not make a particular impression on us, subconsciously we might know that something just does not seem right about what we are seeing and it makes us concentrate on it until we figure out what it is. It does not immediately register in our conscious mind but unconsciously we know something is not right. Ever think about being someplace and your eyes keep going back to something and you have no idea why in the world you are staring at it, then later you find out that indeed something was going on that you were not aware of but you did not find out what it was until later? Sometimes we find out that we were in danger and were not even aware of it. They say if you feel something is wrong, act upon it. Your brain knows but your conscious might be slow to pick up on it.
On the flip side, we can be deceived by what we perceive with our senses. As we age our eyesight deteriorates and what we think we see is not what is actually there. We may listen to a conversation but because we cannot hear clearly (and are embarrassed to admit that), we may act upon wrong information. As we age we use our senses to make decisions based on what we see and hear but we cannot always rely on them to tell us the “truth”.
How do we establish what are "truths"? Our senses process information based on iour perceptions but there are also truths which are not universal truths. These are Subjective Perceptions based on each individual and are based on what we can do. For example a person might be told to paint a picture using primary colors and have another group of people grade how well the person interpreted the instructions. Someone might draw a picture that includes a major element in brown and might be graded with a failure because of this. Why? The grader might be color blind and see the red element as being brown and think the artist missed the mark. Of course the artist did not but the perception of the grader and the perception of the artist. What is a truth for one person does not necessarily mean another person holds the same truth. The artist might try to communicate his perception to the grader but that is not reliable either because then their communications are subject to being exaggerated, falsified and/or misinterpreted.
I have to conclude that our senses are important to us because without them, it would be nearly impossible for us to function; however, senses are imperative for us to be able to make judgments, and to be able to make conclusions which formulate our reality.

...Can you really trust your senses and the interpretation of sensory data to give you an accurate view of the world? Describe and discuss the accuracy and the weaknesses of the human senses as they pertain to think in general and to your own thinking in particular. What perception means and how is relate to our senses? According to Joe Stratton (1999) on his book Critical Thinking for college students stated that “perception is the process of selection, organization, and interpretation of the sense-data into mental representation that can be use by the brain and the nerve system to provide content for thought” (p. 17). We can understand as Perception the process by which we receive and interpret information coming from the environment or ourselves. This information is received through the five senses: Sight, hearing, taste, touch and smell. Sensory perception is not sufficient to identify the outside world, it is necessary also the intervention of other processes such as attention, memory, and imagination. In other words, perception is how we understand and interpret the world. We perceive the world in certain ways depending on our beliefs is like a filter between us and the reality, the memories and experiences that we have stored in our subconscious mind and our capacity of imagination is responsible for how we can perceive the reality. The perception varies from person to person; different people perceive different things in the same situation. “This sensing-thinking......

...EXPERIMENTATION ON SIMPLE REACTION TIME (SENSES: REACTION TIME) Date conducted July 04, 2015 Introduction How do we know the reaction time of its senses? Which of the senses is more sensitive and very fast in receiving information? How do we read laboratory primers and organized data into summaries and graphs? We will find out from this experiment the sources of reaction time. We shall identify also the early programs of research on RT. We will compare which of the sense is slow or fast in receiving information. OBJECTIVES: -This experiment aims to acquaint us in reading laboratory primers and organized data into summaries and graphs. -This experiment aims to identify which of the senses is more sensitive and very fast in receiving information and which of the senses that is very slow in receiving information. -It sought to know the reaction time of its senses as well as the average reaction time. Background and Related Literature: According to studies such as those done by Brebner and Welford published in 1980, mean auditory reaction times are .14-.16 seconds and mean visual reactions times are .18-.2 seconds. The time it takes for the signal to reach the brain was also found by these studies; it takes auditory stimulus .08-.1 seconds to reach the brain while visual stimulus take .2-.4 seconds to reach the brain. Based on this information as well as that from the experiment, a new hypothesis and prediction were being proposed such that if it does takes......

...system consists of the five main senses: sight, hearing, smell, touch and taste. Each individual sense posses their own advantages and disadvantages, but all are crucial to a person’s survival. However, many individuals still take these natural gifts for granted. This is where the same question continues to surface; “if you had to give up one of your senses, which one would you select?” In other words, which sense could a person do best without? I think about this every single time I spend time with my little cousin Jolie who is deaf. I contemplate to myself how it is that she copes and manages? When will she realize she is different? Is it when she sits in school surrounded by her classmates who are able to sing the little hymns to learn their alphabet? Or is it when she has to place a massive hearing aid in her ear every morning before class? The sad truth is she was never given a choice in the matter of her hearing. She will always be considered as one of the “unlucky” ones! If I had the choice I would not allow her to maneuver this uphill battle alone. Choosing which of the five senses to give up would be a fairly easy choice for me. I derive at my perspective rather from what I would keep for my sacrifice as opposed to what I would give up. Undoubtedly I would give up my sense of hearing. For me personally, giving up my hearing would be the most logical decision. In addition, rumor has it that when you lose one sense the other senses become heightened. Sight......

...THE SENSES Hilgard morgan and Sartain explain that there are more than eight senses that we use to explore and learn about the world.Each of these senses has a specific sense organ within which are receptor cells or receiving mechanisms that are sensitive to certain stimuli in the environment. The Eye Is the organ of vision, is sometimes compared to a camera lens because it works roughly the same way as the latter which focuses images of objects at various distances o the film as it moves toward or away from the place of the film. The lens of the eye focuses light images on a sensitive surface.This surface in the eye is the retina,which is composed of rods and cones. Rods which are cylindrical and number about 100 million,do not distinguish colors but are more sensitive to light than are the cones. Cones which are conical in shape and more than six million in number,allow us to see the different wave lengths of light as different hues or colors. Hilgard presents the process of seeing,light enters the eye through the cornea,a tough transparent membrane.The amount of light entering the eye is regulated by the diameter of the pupil,a small hole in front of the eye formed by the iris.The iris consists of a ring of muscles that can contract or expand,thereby controlling pupil size. The Ear Is the sense organ of hearing which is sensitive to sound waves,the mechanical vibrations in the air. There are three parts of the ear:The outer......

Six Sense

...object / experience our natural senses try to analysis that experience and the information that is obtained is used to modify our interaction with the environment. The sixth sense technology is an effort to connect this data in the digital world in to the real world. Sixth Sense Technology is a mini-projector coupled with a camera and a cellphone. Sixth Sense can also obey hand gestures. The camera recognizes objects around a person instantly, with the micro-projector overlaying the information on any surface, including the object itself or hand. Also can access or manipulate the information using fingers. Introduction Although miniaturized versions of computers help us to connect to the digital world even while we are travelling there aren’t any device as of now which gives a direct link between the digital world and our physical interaction with the real world. Usually the information is stored traditionally on a paper or a digital storage device. Sixth sense technology helps to bridge this gap between tangible and non-tangible world. Sixth sense device is basically a wearable gestural interface that connects the physical world around us with digital information and lets us use natural hand gestures to interact with this information. The sixth sense technology was developed by Pranav Mistry, a PhD student in the Fluid Interfaces Group at the MIT Media Lab. The sixth sense technology has a Web 4.0 view of human and machine interactions. Sixth Sense integrates digital......

Chemical Senses

...Chemical Senses Robert J. Bernal June 6, 2016 Robert Levitt, Instructor University of Phoenix Intro The senses of smell and taste are chemically based senses that are unique to the other senses in the way in which the brain interprets them. Unlike other senses which are perceived and categorized analytically, taste and smell both pass through the emotional response center of the brain on the way to their being stored as memories, evoking an emotional association to their formation as engrams. Consider the unlikely association between taste and smell and the emotional response that they can trigger; a chemical reaction that gives off a gaseous “odor”, completely quantifiable by scientific standards, can trigger a purely emotional, unquantifiable response. The question then becomes, how do smell and taste play on our emotions? How do Smell and Taste Effect Each Other? The senses of smell and taste are integrally linked, the ability to do one without the other is not possible with the way that the brain is wired. Physiologically speaking, the way that humans are “designed” or the way that we have evolved is that the nose and the mouth are located in proximity to each other. This means that as we taste a food we are also inhaling particles that create the aromas that are generated by that food, and the brain’s interpretation of the stimulus from the taste buds along with the olfactory sensors in the nose is simultaneous; the memory engrams that form based on...

They are very important in our lives because we would use one of them every moment of every day. They also work together to let our brains know what are going on around us, in other words, they are protector by warning us of any danger. However, any quick change to any of the five senses can cause the feeling of dizziness or unsteadiness. You might have experienced this while riding in a car or turning quickly. Sight: Eyes are the organ of vision. The function of our eyes are the same as cameras, as we can see images from the world and send information to our brain. Then, the brain processes the information, therefore we can see movement, color, depth and shape. Sound: Ears are the organs of hearing. The function of our ears is collecting sounds, and hearing helps us to learn and communicate to others. We can hear a huge range of sounds, from a deep bass to a high-pitched whistle and those sounds will change into electrical signals to the brain to process. Therefore, the brain uses the sounds from left and right ear to determine distance and direction of sounds. Taste: Tongue is the organ of tasting. The function of our tongues tastes four different flavors, which are salty, sweet,......

Sixth Sense

...Name: Anas Awad “Sixth Sense” 1. What is sixth sense?Sixth sense, or subtle perception ability, is our ability to perceive the subtle dimension or the unseen world of angels, ghosts, heaven, etc. It also includes our ability to understand the subtle cause and effect relationship behind many events, which is beyond the understanding of the intellect. Extrasensory perception (ESP), clairvoyance, premonition, intuition are synonymous with sixth sense or subtle perception ability.2. How do we perceive and understand the unseen world?We perceive the gross or seen world through the five physical senses (i.e. smell, taste, sight, touch and sound), our mind (our feelings), and our intellect (decision making capacity). When it comes to the unseen world or the subtle world, we perceive it through the five subtle senses, the subtle mind and the subtle intellect - more popularly known as our sixth sense. When the sixth sense is developed or activated, it helps us to experience the subtle world or subtle dimension. This experience of the subtle world is also known as a ‘spiritual experience’. | | In the above picture, we see a lady who smells a bunch of roses. This would constitute an experience as there is a definite source to the fragrance of roses i.e. the bunch of roses.

Senses in Dining

...Role of the senses in a human dining experience Food in recent times has evolved beyond just the taste buds. Eye appeal, smell and textures have now become involved in a complete dining experience. Today it is not just about how good the food on your plate tastes, but also about where you eat it, how it looks on your plate, how you eat it, the sounds, if any emitting from it and how it smells. In short it involves all senses in the human body. Where you dine is an important aspect in what you take out of a meal. If you have the same food at a roadside dhaba and at a Michelin star restaurant, it will still feel and taste different because of the different dining environments. Ambience is an important aspect of the dining experience. This is the reason why restaurants spend a pretty penny on getting the look of the dining area just right in order to give their customers a unique meal. In ethnic or specialty restaurants, the entire focus is on recreating the atmosphere, which is why you have traditional art work on walls, mirrors and staff wearing traditional clothes as a fixture in Indian specialty restaurants or pictures from 50’s America along with car seat type seating in an American themed diner. Customers also get unconsciously perceived signals from the restaurant décor. Bright lights and loud colours, as found in most fast food joints gets them to hurry up and complete their food whereas subdued colours and dim lighting in upscale restaurants gets them to relax,......

Chemical Senses Final

...Chemical Senses Julie Harris PSY/345 September 28, 2015 Adam Casteberry Chemical Senses Chemical sensory is the process by which the body experiences the world through the sense of smell and taste. The process the brain uses to perceive the smells and tastes that are introduced to it is through an electrical mapping of electrical impulses similar to the sense of touch, sight, or sound. Each sense is individual but through the interaction of each a more whole picture is produced that the brain stores as a memory. Most adults have their memories peppered with the smells and tastes that helped create those memories whether it was the first time a person was asked to be married, or the first time a person faced death, each experience is marked by a distinct taste or smell that will call up the memory and shape the person who holds it. The process of chemical sensory is conducted mainly through the nose and mouth through a bombardment of sensations is experienced throughout each day. Once considered separate from each other as either the nose or mouth people have become aware of the connection between the two senses as being tied irrevocably to each other. Chemicals in foods are detected by pallia that we have labeled taste buds, small structures in the mouth that are embed in the tongue, the back of the mouth, and the palate (Society for Neuroscience, 2012). Each person has a range of 5,000 to 10,000 taste buds that consist of 50 to 10 sensory cells that are stimulated...

Human Sense Organs

...Tiffany Herring B. LaFond PSYC 1000 Human Sense Organs As human beings we have 5 different human sense organs. These sense organs are sight, smell, touch, taste, and hearing. Our 5 sense organs help each of us and how we perceive reality and the world around us. Without our sense organs we would have a much harder time understanding the world we live in. Each of our different senses have specialized organs that are set up to receive specific stimuli, these are linked to the nervous system and from the nervous system then linked to the brain. The first sense organ is sight. The eye is the organ of sight. The basic structure of the eye consists of a transparent lens that focuses light on the retina. The retina is covered with two types of light-sensitive cells called cones and rods. The cones are sensitive to light whereas the rods are not they have a greater sensitivity to light. The eye is connected to the brain by the optic nerve. Our brain takes the two different images from our eyes and turns them into a single 3-D image. One of the most amazing things I learned about the eye was that our eye actually sees things upside down but when our brain processes the images it sees it turns them right side up and that is the image our brain shows us. Smell is our second sense organ. The nose is the organ we use to smell. The nose is lined with mucous membranes that have smell receptors that are connected to the olfactory nerve. Smells are made up of a variety of......

A Sense of Self-Worth

...with decorum? “The Box Man”, from Barbara Lazear Ascher’s essay, displays dignity through grace, distinction and worth, despite his lack of address. Though homeless, he projects self-respect, not caring how the rest of the world views him. First, as the bandaged, blistered legs and the dark doorway fade into the background, he shows a graceful, meticulous arrangement of belongings around his flawless setup of boxes. In her essay, Ascher describes his imaginary living room with “Six full shopping bags…distributed even[ly] on either side.” (Ascher 6) Even in his unstable environment, which most people would find distressing, he creates homely comforts. The way in which he arranges and places himself in this atmosphere states an undeniable sense of grace. I can envision The Box Man in a room with distinct lines, sensual fabrics; a different ambience altogether. Second, he takes his damaged, ragged body and lowers himself to his makeshift seat; just as a tired, distinguished business person would light upon a train bench. The author illustrates, “[The Box Man] pulled out a Daily News, and snapped it open against his cardboard table. All done with the ease of IRT Express passengers.” (Ascher 6) He shows a distinction; poise, so to speak, of a man who was used to being important. The distinction in his movements and gestures shows this even if he has never been of high stature. The Box Man doesn’t fade into the backdrop, his mannerisms set him apart. Third, The Box Man......
