Does this number 5 appear as a color? Or does the word “calm” give the taste of something soothing? No? That is ok; all that means is a rare Neurological disease known as Synesthesia is not present. Synesthesia is Greek for “syn=together and aisthesis=perception” (Cytowic, 1995) and by definition means “joined sensations” (Ciccarelli & White, 2012, p.88), meaning that two of peoples 5 senses are connected together. Normally this is a fusion of sound and sight, but this can also include taste, touch, and smell for some people. Let’s delve deeper and learn more about what Synesthesia is exactly.
Synesthesia was first discovered in 1812 and at the time was thought to be a mental disorder or a type of insanity (Than, 2011). This of course was 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 people posses’, therefore giving people who have this Neurological problem a remarkable amount of variations of Synesthesia. A few of the more common types are Grapheme-Color, Sound to Color, Number 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” may appear red and the letter “B” may appear as yellow. All colors are not the same for all Synaesthetes, they are pretty similar among the majority.
Sound to Color is when certain sounds trigger generic colored shapes. Such as a loud sound may express itself as circle that is Orange. It’s important to note that not all sounds trigger a colored shape, and that most shapes are simple like squares and circles.
Number form Synesthesia allows people to form a mental map and has been suggested that ...

Hopefully I was able to shed some light on a fairly new studied neurological disorder, and also maybe give people some perspective on how others see the world. Or even better yet shine some light on people who do have this disorder to realize that what they have is a truly unique way to see the world.

Modern human brain sizes are significantly smaller than Neanderthal’s and so are their brain cavities. TAS2R38 is the gene that controls taste. For Neanderthals, having a bitter taste “system” could have kept them from poisoning themselves by accident.
In this paper, I will argue that it is more likely that the qualia of colour could be explained by physicalism rather than by property dualism. Qualia are subjective experiences, such as our senses (pg. 3). Physicalism views every property as physical, and can be explained by science (pg. 29). Property dualism refers to the philosophical view that minds are made out of one substance, but contain physical properties, and a non-physical mind (qualia) that are not related to each other (pg. 29).

Webster dictionary defines synaesthesia as “a subjective sensation or image of a sense other than the one being stimulated” (Wyld,1963). Synaesthesia is a condition that causes someone to have associations of usually color with certain everyday things, such as numbers or letters. There are several different types of synaesthesia that will be discussed in this paper digit-color synaesthesia, odor-color synaesthesia, and person- and music-color synaesthesia. A common effect that is discussed when talking about synaesthesia is the McCollough effect. This effect is a wonder of humans and their visual perception where colorless gratings appear to have a color.

Being a psychology student, one learns many amazing things that can happen to people. One of them includes synesthesia. Synesthesia is a natural occurrence where a person experiences multiple senses at one time. For example, somebody with synesthesia may see a color when somebody is talking to them. Another example is when they touch something, they also experience smell. This happens without the person trying at all. One of the most popular types of synesthesia is Grapheme. This means that people see letters and numbers in colors automatically without any effort. Most people with synesthesia experience it their whole life, so what implications does it have on synesthetes childhood, especially when being and school with other children who are considered typical students? We will look at several studies that have observed children with synesthesia and their experiences in the education system.
A recent neurobiological approach to understanding consciousness, at least on a perceptual level, has involved the study of the phenomenon of blindsight. Damage to areas of the visual cortex often result in complete or partial blindness. Although the eye itself is undamaged, patients report an inability to detect any light input in part of (or the entire) visual field. However, experiments regularly show that somehow, visual cues are processed. Visual inputs presented to the blind field affect the patient's response to stimulus in the normal visual field. Reaction times to stimuli are affected as well as the interpretation of the stimuli. A visual cues presented in the blind field may suggest a certain interpretation of an ambiguous stimuli. For example, the interpretation of the word "bank", presented as an auditory cue, differs depending on whether the word "river" or "money" is presented to the blind field, even though the patient does not...
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
Imagine yourself in an art museum. You wander slowly from cold room to cold room, analyzing colored canvases on stark white walls. When you reach a particular work, do you prefer to stand back and take everything in at once? Or do you move so close to the painting that the individual brushstrokes become apparent? Several different sensory processes occur in your brain during this trip to the art museum; the majority of them involve visual inputs. How does your brain put together all the information that your eyes receive? This raises questions ranging from depth of field to color. The ideas of color perception and color theory are interesting ones. How do humans account for color and does it truly exist? I think that by examining not only the neurological on-goings in the brain, but by learning about color through philosophy, and even art, a greater understanding of it can be reached.
Subliminal or unconscious perception refers to the idea that stimuli presented below the threshold for conscious awareness can influence an individual's thoughts, feelings, or actions (2). The possibility that an individual can acquire and act on input without being aware of doing so has implications for the study of consciousness and the larger set of processes which characterize the I-function. It is generally assumed that that conscious perception of a stimulus is necessary in order to act on that stimulus, and this conscious decision to act is one of several processes which characterize the I-function.
The way that our brain processes information and responds to the awareness of things is a very complex system with in the brain. One study mentioned talks about the integration of senses in the brain and how we process the information. “Another study better illustrates the integrative nature of this synchrony. Words were presented in various locations on a screen; whether the subject became aware of the word’s color or if its location-indicated by being able to recall is later-depended on whether a frontal or temporal area was activated during the presentation. But if the individual registered both the color and the location, additional activity occurred in a part of the parietal cortex (Uncapher, Otten, & Rugg, 2006).” (Garrett, pg.501) This research demonstrates how different people react differently to stimuli and different levels of their cognition and awareness. It is important for people to develop a sense of awareness in order to function fully in the world. The book argues “that one apparent advantage is that it enables consistency and a playfulness in our behavior that would not be possible otherwise. (Garrett, pg. 502) It is human nature to rely on a consistency and the ability to plan ahead which is why the function of awareness is so important to the human
With each of our senses (sight, smell, touch, taste, and hear), information is transmitted to the brain. Psychologists find it problematic to explain the processes in which the physical energy that is received by the sense organs can form the foundation of perceptual experience. Perception is not a direct mirroring of stimulus, but a compound messy pattern dependent on the simultaneous activity of neurons. Sensory inputs are somehow converted into perceptions of laptops, music, flowers, food, and cars; into sights, sounds, smells, taste ...
