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 ear,Midle ear and the inner ear.The two main sensations in hearing are those of pitch and loudness.Sounds pounds on the eardrum which moves the three bones of the middle ear.the last of the three bones,the stirrup,vibrates the surface of the inner ear,which transmits the mechanical force of the fluid inside.
The outer ear consists of pinna,the protruding part of the ear which catches sound…...

The Senses

...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......

...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......

Common Sense

...Common Sense Common sense is the knowledge and thinking ability a person acquires through experience and from teachings passed on from others, and is used to deal with everyday life in appropriate manners. It is what a person relies on to tell them, generally, what is right or wrong, good or bad, and what is best for them in a given situation to sustain overall well-being. It reflects the thought process that is used when faced with possible uncertainty, and it relies heavily on memory. It enables someone to compare their present to moments of their past and to use judgment based on connections between the two (sometimes in opposition to logic). In other words, common sense is a person’s intuition, and this instinct is constantly molded over the course of their lifetime. It can be agreed that experience and guidance in the early stages of life leads to better common sense. From birth, parents influence the instincts and thinking skills that their children develop. They teach their young to use their senses to navigate the world around them. Parents also guide their children through understanding what their senses are telling them. It is during this early-life period that children acquire reasoning and memory skills which will be used for the remainder of their lives. For example, whenever a child plays outside in chilly weather, the mother will encourage them to bundle up so that they do not catch a cold. However, when that child does not listen and gets sick, they......

Sense and Sensibility

...Book Report - Sense and Sensibility  In Jane Austen, Sense and Sensibility, the title is a metaphor for the two main characters Elinor and Marianne. Elinor represents sense and Marianne represents sensibility. We find out early that Elinor does not share her feelings. When Edward comes into the story, there was an immediate attraction. She tells no one of her feelings. It was just assumed that they are meant for each other. When Edward has to leave, Elinor says nothing. Edward does promise he will come down and give Margaret an atlas. When the atlas comes and not Edward, the one who ends up crying was Margaret and not Elinor. We do learn, however, that Elinor can get emotional too. When Marianne was playing the piano at their new cottage, Elinor cries as she listens. She said the song was her late father's favorite. Later on in the story, Marianne kept on nagging Elinor for not sharing her feelings. Finally, Elinor shows her emotions by telling her that she did have a broken heart after she found out that Edward had a fiancee - Lucy. Elinor would definitely represent sense. She keeps her thoughts to herself. Maybe it is because she thinks she will not end up hurting so bad as Marianne did.  Marianne, on the other hand, represents sensibility. She follows her heart. She does not let anything come in the way of showing her emotions. When she first met Colonel Brandon, it is obvious that he was in love with her at first sight. Marianne, shows very clear that she was......

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......

...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......

...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......

Sense of Wonder

...Seeing the World With a Sense of Wonder . In Moore’s novel, Wild Comfort, she explains how significant contact with the natural world brings comfort to you and makes you have a sense of wonder. Significant contact with the world is anything from smelling, hearing, seeing, or touching the natural world. Throughout the book Moore has a sense of wonder and adventures off into nature. By interacting with nature, she’s able to make connections to her own life. She makes it clear that nature has a healing power and people should get in contact with it. Moore defines sacred as a “worthy of reverence and awe.” She strongly believes the world we live in is a sacred place. One of Moore’s experiments that she did, “The Happy Basket”, she discovered that “significant contact with the natural world” is a vital key ingredient to happiness. Each day Moore would write down what made her happy. A common thing that made her happy was taking part in the natural world. One of Moore’s happy moments was, “I’m lying on my back under ponderosa trees by Davis Lake…I had gone out to look for birds, but this is better, letting them come to me” (Moore 26). We are fortunate to have nature, but many take that for granted and just go on living their busy lives. Humans today should take a moment to pause and get in significant contact with the natural world. To take time to appreciate their surroundings. They need to see the bigger picture or you don’t know what’s going on. People need to take a......

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...

Common Sense

...1. Why does Paine write Common Sense anonymously and how does he think his work will be remembered? "In the following sheets, the author hath studiously avoided every thing which is personal among ourselves. Compliments as well as censure to individuals make no part thereof. The wise and the worthy need not the triumph of a pamphlet; and those whose sentiments are injudicious or unfriendly, will cease of themselves, unless too much pains is bestowed upon their conversion." (Thomas Paine) So, basically as much as the book means for the colonists, Paine wanted to be on a rather neutral ground. He had no need for the glory that brought forth by a pamphlet (which is the whole Common Sense) nor he wanted to go against those who would certainly punish him for what his work brought forth. He himself clearly said that only those who got too hurt emotionally by sins they made would spare him for what he wrote. (aiming at the authorities who used violence to suppress the colonists) It is merely a guess from my part but I think what he meant was that he should not be the one the sacrifice but instead the colonists who were being suppressed at the time. He did not want them to rely on anyone but themselves to save their own life. Thus, he probably thought that his work would remain as something written by basically no one at all but merely created by the people' passions for freedom. On other words, the work was only there to raise the spirit of colonist to fight for their own lives......

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.

...and “happy hours” at bars. “Early Bird” discounted prices for early diners at restaurants. Standby airfares on commercial airlines. Supermarket coupons. Discounts for students, teachers and professors on computer software. • • • The consumers receiving the discounts are those with the highest price elasticity. It follows that the higher the price elasticity of demand of the average customer, the more the supplier will need to accept lower prices. What it boils down to is that price elasticity of demand puts limits on the market power of suppliers. The greater the price elasticity of demand, the lower the market power of suppliers. Remember that price elasticity of demand depends largely on the availability of substitutes. So it makes sense that the greater the availability of substitutes, the less market power the suppliers of the particular good or service will have. The greater the availability of substitutes, the more that suppliers become price takers, rather than price makers.
