Essay On Sensory Perception

972 Words4 Pages

In the real world, much of what we know is reliant on our sense perception – including the construction of scientific knowledge. That means that we should be able to trust our faculties of sight, smell, hearing, taste, and touch, by which the body perceives an external stimulus which will be consistently good in quality or performance. We use sensory perception as one of our ways of knowing, which is how we acquire knowledge about the world around us, and figure out our relationship with it. However, is sense perception a reliable way of knowing and constructing scientific knowledge? The strength of sensory perception is that sensory perception includes sight, which allows us to have a better understanding of the processes we see in the natural …show more content…

Our senses are limited and we are not able to sense and perceive things that are out of our range. For example, a human’s hearing range is generally from 20 Hz to 20 kHz, but it is far more sensitive to sounds between 1 kHz and 4 kHz. The range of sounds that humans can hear can have a difference of about 120dB, and we can only recognize a change in volume when the signal is altered by 1dB, which is a 12% change in amplitude. For us humans, there are only about one hundred and twenty different levels of loudness that we can perceive. This is why ultrasound devices are invented, helping us to better understand the world around us and letting us realize that there are many other sounds which we as humans cannot hear because of the limitation of our hearing range. Our sight is also limited as seen from how we cannot see things such as cells and atoms. However, for scientists to arrive with a conclusion that atoms are the basic unit of things and cells are the basic units of living things, they would have to be able to sense and perceive them before they can confidently write a report and study these subjects well. This is why humans need the help with mechanisms such as microscopes to help us zoom in and study these topics well. But how do we know if the mechanisms that we use to help improve the range of our senses are reliable and if our senses are reliable in perceiving whatever we see through these

  • The Hundred Secret Senses Analysis

    882 Words  | 4 Pages

    The archetypal pattern that dominates The Hundred Secret Senses and structures the plot is the cycle of birth and death and rebirth, a pattern that is mirrored by the constant renewal in the natural world as winter gives way to spring and then summer, or the wet season succumbs to the dry months, year after year, century after century. Throughout the novel, birth and death are juxtaposed, linked in ways that suggest the clear relationship between the two events in Kwan’s stories as well as in the grand cycle of the universe. As a result of Jack Yee’s death, Kwan is ‘born’ into the Laguni family to become Olivia’s loyal sister and friend, as well as her guide to a previous life. Years before that, Buncake must die so that Kwan can return to life, ‘reborn’ in her friend’s body-again, so that eventually she can become a part of Olivia’s life. And a century earlier, before Kwan’s story begins, Yiban Johnson, born immediately after his mother’s suicide by hanging, grows to manhood and falls in love with Nelly Banner, only to lose her because Nunumu fails to realize how well Yiban can deduce Miss Banner’s thoughts.
