Does this number 5 appear as a color? Or does the word “calm” give the flavor of something soothing? NO? All right; all of which means that a rare neurological disorder known as synesthesia is not present. Synesthesia in Greek means “syn=together and aisthesis=perception” (Cytowic, 1995) and by definition means “joint sensations” (Ciccarelli & White, 2012, p.88), which means that two of people's 5 senses are connected Together. This is normally a blend of sound and sight, but for some people it can also include taste, touch and smell. Let's dig deeper and learn more about what exactly synesthesia is. Synesthesia was first discovered in 1812 and was thought at the time to be a mental disorder or type of insanity (Than, 2011). This has obviously been disproved by today's ability to examine the human brain. As stated before, synesthesia is the combination of two or more of the five senses possessed by people, therefore offering people who have this neurological problem a considerable amount of synesthesia variations. Some of the most common types are Grapheme-Color, Sound-Color, Numeric Form, Personification, and Lexical Gustatory. The first two are as simple as they sound; Grapheme-Color involves people seeing letters as colors. For example, the letter "A" might appear red and the letter "B" might appear yellow. All colors are not the same for all synesthetes, they are quite similar among the majority. Sound to color occurs when certain sounds activate generic colored shapes. For example, a loud sound can express itself as an orange circle. It is important to note that not all sounds trigger a colored shape and that most shapes are simple like squares and circles. Numerical form Synesthesia allows people to form a mental map and it has been suggested that... in the center of the card... ....t?I hope I have managed to shed light on a fairly new neurological disorder and perhaps even give people perspective on how others see the world. Or better yet, shine a light on people who suffer from this disorder to realize that what they have is a truly unique way of seeing the world. Works Cited Works Cited Cytowic, R. E. (1995).
