From the textbook ‘Thinking’, chapter 3 explains how our senses enable us to think. Your senses gather information about the world around you. The five senses are needed to help you find food, resist heat or cold, and avoid situations that might be harmful. Your ears, eyes, nose, tongue, and skin sense changes in the environment. Nerve receptors send signals about these changes to the brain, where the information is processed. (2010, The World Almanac for Kids). This paper will explore accuracy or inaccuracy of sensory information , as well as, the roles of nature and nurture with regards to the interpretation and evaluation of sensory data. The senses can be misinterpreted and even mislead by perceptions that can deceive our brain in three major ways. Our senses are limited biologically. Some examples of what is meant by this are that most people have 20/20 vision and under normal circumstances can see for over a couple of mile. However, we are limited we can see molecules or atoms and we can’t see something ten miles away or even in the dark. Humans can hear sounds at a frequency as high as 20,000 hertz. Our sense of taste is limited to only five distinct sensations: sweet, salty, sour, bitter, and the newly discovered “umami” or savory sensation (Encyclopedia Britannica).
