Sense perception is understanding gained through the use of one of the senses such as sight, taste, touch or hearing. It is one of the ways of knowing through which we perceive information. It is extremely interesting to explore how and why animal senses are different from human senses. Some animals have developed amazing adaptations to their environments. The animal kingdom has plenty of creatures whose senses go beyond what we can conceive.
The star-nosed mole is essentially blind. However, thanks to the tentacle star nose, the mole has perhaps the best sense of touch of any mammal in the world. It uses its nose for hunting. The Star-nosed mole has 100,000 nerve fibers that run from the star nose to the brain, approximately six times more than the touch receptors in the human hand.
A bird's eyesight is its most critical sense and the one it relies on the most for flight, evading predators and finding food. Birds have a thicker retina than humans and their eyes are larger in proportion to their head size. They have much denser rods and cones packed on the retina, giving them superior vision in both black-and-white and color.
A falcon can see a 10 cm object from a distance of 1.5 km. Its visual acuity is 2.6 times better
What enables this ability is the jelly-filled canals in their head called the ampullae of Lorenzini that detects electric fields. Because salt water is such a good conductor of electricity, sharks with a refined sixth sense can detect their prey from the electrical charges that are emitted when a fish contracts its muscles. It may also serve to detect magnetic fields which some sharks may use in navigation. Also, Sharks have a keen sense of smell meaning that they can perceive a drop of blood in 100 liters of water thanks to the nostrils, through which water continuously flows. Sharks have amazingly developed senses that humans don’t
What is sense perception? Everything we perceive in our senses can be misleading and an illusion. In the article “Perception and Reality” by Keith Wilson (see Article 1), the author goes over some of the aspects of how our perception deceives us to believe in things that aren’t there to begin with. For example are colors real? Well that is relevantly dependent on what is considered real, because real again is a perception of a single individual collecting information and making “sense” out of it. A color being real or not is dependent on how we see it through our eyes, we can 't say that my blue is the same as your blue. We can 't know for sure if what we are seeing for ourselves, is the same as what the person that views that same thing sees
Vision plays a huge role in the lives of non-human primates. Non-human primates have exceptional binocular vision, due to forward-facing eyes with overlapping visual fields (Prescott). This binocular stereoscopic color vision allows primates to see the world in terms of height, width, and depth, also known as three-dimensional vision (Haviland et al. 2010). Highly developed vision allows the later arboreal primates to judge depth, distance, and location when moving at speed from branch to branch (Haviland et al. 2010). This bino...
In this lab we apply the technique known as a two point discrimination test. This test will allow us to determine which regions of the skin are best able to discriminate between two simultaneous sensory impulses. According to (Haggard et al. 2007), tactile discrimination depends on the size of the receptive fields located on the somatosensory neurons. However receptive fields for other types of sensations are located elsewhere. For vision we find that the receptive fields are located inside the visual cortex, and for hearing we find receptive fields in the auditory cortex. The ability for the body to discriminate two points depends on how well that area of the body is innervated with neurons; and thus conferring to the size of the receptive fields (Haggard et al. 2007). It is important to note that the size of the receptive field generally decreases in correlation to higher innervations. As was seen in the retinal receptive fields, the peripheries of tissue had contained larger receptive fields (Hartline, 1940). In our test we hypothesized that the finger region will be able to discriminate better than the forearm. This means that they will be much more innervated with neurons than the forearm, and likewise contain smaller receptive fields. This also means that convergence is closer to a 1:1 ratio, and is less the case the farther from the fingers we go. We also think that the amount of convergence is varied with each individual. We will test to see if two people will have different interpretations of these results.
Horses use touch to convey to other animals that they like them or dislike them. Meaning that if a horse is pleased and likes something they may nudge their head on it, rub the side of their face on the object and be very gentle. If they are displeased they may swing their head at it, buck it, bite or stomp. These behavior displays of touch show th...

On average they weigh 4,000-7,000 pounds and grow approximately 16-20 feet long ( Great white sharks 1). < commentary needed>Great Whites are the apex predator of the ocean containing 300 serrated teeth and highly-developed senses to hunt prey. Sharks have a great senses of smell, the Great White can smell a drop of blood thousand of miles away. They’re hearing is very powerful , being able to hear the vibrations of prey distances of about 800 ft away and find the exact location through ‘ear stone’( Great white 3). A shark 's sense of hearing truly shows their uniqueness as an apex predator. In addition to great hearing they’re known to have great sight by being able to see up to 50ft away and transition into seeing in light and dark. Additionally sharks have a lateral line on their back that reaches from the front to the back tail, allowing
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the
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.
Each one of us lives in our own unique world of perception. As individuals, we may experience life in an entirely different way through our senses and life experiences. Therefore, perception can be tricky since it is very personal to each one of us. According to the Merriam-Webster online dictionary, perception has three meanings; (1) “the way you think about or understand someone or something,” (2) “the ability to understand or notice something easily,” and, (3) “the way that you notice or understand something using one of your senses” (2014, para. 1). C.S. Lewis said, “What you see and what you hear depends a great deal on where you are standing. It also depends on what sort of person you are” (n.d., para. 11). In other words,
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
Lastly, behavior can also be determined by sensation and perception, the stages of processing the information gathered from the senses. Sensation and perception depicts the world for humans. Without them, humans would not be able to truly experience what is going on around them. The first step, sensation, is the gathering of the information from the outside would through the five senses: sight, hearing, taste, touch, and smell. The information is then organized and interpreted by the brain through
The five senses of sight, hearing, touch, taste and smell are all sensations throughout the human body. Sensation is the involvement of sensory receptors as well as the central nervous system in order to allow us to experience outside stimuli. The system that allows us to experience sensation is the sensory system.
Vision and sight sense are the most important of all. Why sight and vision are important is because; You would not be able to see where you are going, where you are at or what is around you without sight. You could hear and listen, taste and discern, smell and distinguish and touch and compare, but without vision you can not prepare, be aware or observe what you may not be able to hear, smell, touch, taste.
Perception is defined as the process of organizing, interpreting, and selectively extracting sensory information . Visual perception is left to the individual person to make up their own mind. Perceptual organisation occurs when one groups the basic elements of the sensory world into the coherant objects that one perceives. Perception is therefore a process through which the brain makes sense of incoming stimuli.
