Recommended: Visual sensation and perception

We as humans have special senses. These senses are taste, touch, smell, hear, and see. Also known as auditory, olfactory, gustatory, visual and touch perceptions. These senses allow us to live a normal and easy life. They are called special senses because they are located within their sensory receptors. Vision is one of the dominant senses of our body. This is because our body processes things within a visual aspect. Gustatory and olfactory determine whether what we eat has been savored or avoided. Olfactory and gustatory are able to work because of chemoreceptors. Chemoreceptors allow a response to different chemicals. Auditory does not only help hear extraordinary sounds but it also helps us balance. Equilibrium receptors keep head movements …show more content…

In dim lighting the muscle dilates the eye. Human eyes are not sensitive to the polarization of the light like bee eyes are. Because bee’s eyes are sensitive to the polarization of the light they have a visual range that extends into ultraviolet. Daltonism is a mutual disease in the eyes. Daltonism thwarts a human from distinguishing variations of colors. You can also refer to daltonism as colorblind. An example of being color blind can be not distinguishing the differences from red and green. There are several types of reasons why a person might wear glasses. One of them can be myopia. Myopia is nearsightedness. It has become one of the most refractive eye errors.With myopia a person might have trouble reading road signs or far away objects clearly, but are able to read close up like a book or even text through computer. Symptoms of myopia could be squinting, feeling fatigue when driving staying active like playing a sport, headaches or eye strain. Myopia is provoked when the eye is too long focusing power on the cornea and on the lens. Because of this light rays focus at a point right in front of the retina instead of directly on its surface. Having a curved lens or cornea for the length of the eyeball can also provoke

  • Sensations And Brain Processes By J. C. Smart Summary

    706 Words  | 2 Pages

    Physicalism is the position that nothing can exceed past what is physically present, and what is physical is all that there can be. This idea is reductive in that it suggests there is no more to the universe than physical matters, including brain processes, sensations, and human consciousness. J.J.C. Smart explains sensations as a means of commentary on a brain process. He believes that, essentially, brain processes and what we report as sensations are essentially the same thing in that one is an account of the other. He writes in “Sensations and Brain Processes” that “…in so far as a sensation statement is a report of something, that something is in fact a brain process. Sensations are nothing over and above brain processes,” (145). Though

  • Roles Of Perception In Critical Thinking

    553 Words  | 2 Pages

    Our five senses –sight, hearing, smell, taste and touch help the ways in which we perceive the world around us. And while they seem to work independently at time they can effect each other and the way we comprehend something. Seeing something pretty, touching something soft, eating something cold and smelling something rotten are the sense we use to connect with the world around us and will all effect how we move forward in that situation. When you look at the top picture say the color of the word not the word itself. It is harder than it seems and takes a little practice to do it efficiently. It is because we see the spelling we were taught not the color it was written in. It is hard to process it the other way, but not impossible. Take the bottom picture for another example is this a

  • Amblyopia

    1809 Words  | 4 Pages

    Amblyopia is a condition in which visual acuity in one eye is greatly reduced. It is caused by lack of stimulation or disuse during visual development (Rose, 1998). Because the eye is not fully developed at birth (Jarvis, 1992, as cited in Rose, 1998), infants need stimulation to complete the visual neural pathway. When one or both eyes are inhibited, for example due to misalignment of one eye (strabismus) or a large difference in refractive power between two eyes (anisometropia), the neural pathway for the inhibited eye develops abnormally, or does not develop at all. At approximately six years of age eye development is complete (Stager, 1990, as cited in Rose, 1998). Before visual development is complete amblyopia can be treated. If it is caught and treated at an early age, normal vision can be preserved (Rose, 1998).

  • Sensory Ethnography Essay

    2034 Words  | 5 Pages

    Every person uses their senses to experience their environment differently. It could be because of social and human agencies that influence how they can utilize their senses in a particular way, or it could be how their own personalized hierarchy of senses differs their perceptions in a multi-sensory situation. I want to start by defining what sensory ethnography is, as per Sarah Pink 's explanation found in the beginning chapter of her book "Sensory Ethnography". Pink describes it as an "ethnography to explicitly account for the senses" (Pink 2015 p. 7). It takes the traditional ethnographic approaches used by anthropologists such as participating, living, and qualitative examination and creates a "re-thought ethnography as gendered embodied, and more ...

  • Sensation And Senception: The Process Of Sensation And Perception

    By absorbing information and convert them into a meaningful information, that could help us to understand the life and make good and wise decisions. There is minimal amount of stimulations have to occur, so our organ can detect these stimuluses and that is the absolute threshold, which is basically means that you will not be able to smell something really far from you, unless that thing hit the minimal amount of stimulation and your nose can smell it now. The lack or the loss of one or more sense would make a big gap in how we experience things around us and a perception failure will make it harder to understand the full image of what is going on around us and it will cause an inability to respond to a current situation. For example, if someone is blind, it will be hard for the brain to get the full image and to understand it in order to make a wise decision. But amazingly our brain relays on other sensory organs to get the information that is needed to get a full image in order to survive. I have a friend who was blind since he was two years old, when I asked him how do you see or how do you imagine the chair, he described the chair exactly as we see it, but with no color. His brain works with the lack of visual information as a way to relay on other sensory organs to achieve the same results that we can see and he cannot. It does not mean

  • The Processes of Visual Perception and Visual Sensation

    1240 Words  | 3 Pages

    Visual perception and visual sensation are both interactive processes, although there is a significant difference between the two processes. Sensation is defined as the stimulation of sense organs Visual sensation is a physiological process which means that it is the same for everyone. We absorb energy such as electro magnetic energy (light) or sound waves by sensory organs such as eyes. This energy is then transduced into electro chemical energy by the cones and rods (receptor cells) in the retina. There are four main stages of sensation. Sensation involves detection of stimuli incoming from the surrounding world, registering of the stimulus by the receptor cells, transduction or changing of the stimulus energy to an electric nerve impulse, and then finally the transmission of that electrical impulse into the brain. Our brain then perceives what the information is. Hence perception is defined as the selection, organisation and interpretation of that sensory input.

  • What it means to be human

    1890 Words  | 4 Pages

    First, one must have the five senses; taste, smell, hear, see, and feel. Yes, these are physical aspects, however, these senses are what any human needs to be, human. For example, the human body needs to be able to taste. It must ingest food, and the food must appeal to a decent taste. A human must also be able to smell, so one may smell a poisonous gas, delicious food, or any other stench that may linger in the air. To be able to hear, enables the human to hear danger or a noise that appeals to them. When seeing, danger is also noted as well as the care of others. When one feels, the object that is being felt may make the person feel comfortable. Not only the sense of touching, but feelings.

  • The Common Sense: The Five Sense Of Perception

    Perception, at most times, is a credible way to assess the world around us. Without perception, we would not know what to do with all the incoming information from our environment. Perception is constructed of our senses and the unconscious interpretations of those sensations. Our senses bring in information from our environment, and our brain interprets what those sensations mean. The five most commonly accepted senses -- taste, smell, hearing, sight, and touch -- all help create the world around us as we know it.

  • Hearing vs. Listening

    945 Words  | 2 Pages

    Hearing is known to be an automatic function of the body. According to the dictionary, hearing is, “the faculty or sense by which sound is perceived; the act of perceiving sound,” (“hearing…”). Hearing is a physical and involuntary act; therefore, unless one is born with a specific form of deafness, everyone has the natural ability to hear sounds. Sounds constantly surround us in our everyday environments, and because we are so accustomed to hearing certain sounds we sometimes don’t acknowledge them at all (or “listen” to them). The dictionary definition of listening is, “to give attention with the ear; attend closely for the purpose of hearing,” (“listening…”).

    The images formed on the two retinas are so unlike that they cannot be blended in the brain. Thus, a double image is perceived. The condition is known as diplopia, or double vision. Prismatic lenses are prescribed to correct this defect.Imperfections in the cones of the retina, resulting from heredity or disease, cause defective color vision. This is known as color blindness, or Daltonism. In total color blindness, everything appears in shades of gray.
