The psychological phenomenon of interaction between various senses, that is, the phenomenon of stimulation of one sense triggering another sense, is called "synesthesia" in psychology.
The most common synesthesia is "color-hearing" synesthesia, that is, the feeling of color can cause corresponding hearing. Modern "color music" is the application of this principle.
Color vision also has temperature perception. For example, red, orange, and yellow can make people feel warm, so these colors are called warm colors; blue, cyan, and green can make people feel cold, so these colors are called cold colors.
There is also a kind of color vision called "optical hallucination", which can be accompanied by taste, touch, pain, smell or temperature sensation.
"Speech-color synesthesia" refers to the color vision caused by certain words.
In daily life, people often say "sweet voice", "cold face", etc., which are all synesthesia phenomena.
People often use synaesthesia in activities such as painting, architecture, environmental layout, and pattern design to enhance corresponding effects; some painters have conducted synaesthesia experiments, such as using sharp tonal contrasts to induce a non-visual response; synaesthesia also
Used by many poets as a creative means.
Just imagine what it would be like if sound could be perceived visually and taste could be perceived auditory.
You may see colored notes, taste sweet or salty songs, and touch rough tunes.
Is this fantasy?
No, not at all.
In recent years, people have confirmed through Positron Emission Tomography (PET) studies that each area of ??the human brain is responsible for a certain sensory component, which makes sound belong to the auditory area rather than the visual or olfactory area.
But sometimes two different areas merge, so that colored notes are seen, potatoes are heard, and a group of identical numbers among many numbers is immediately recognized because the numbers are distinguishable by color.
This is the phenomenon of synesthesia.
An ability that is lost as a person grows up. Potentially, everyone can experience the feeling of synesthesia. The only difficulty lies in raising this perception to the level of consciousness.
American neuroscientist Richard Cytowic said in his book "The Man Who Tasted Shapes": "We can compare feelings to television broadcast signals.
The TV signal travels from the studio to the TV. The picture that appears on the TV screen can be compared to our normal perception. The signal is converted into TV image information at the end of its journey.
By intercepting the signal mid-transmission and interpreting it, we see something different than what we see on television: the experience is comparable to the experience of synesthesia." Over the course of 15 years of research, Sitowick estimated the phenomenon's potential for use.
Incidence in the population: Approximately 1 in 25,000 people have stable synesthetic perceptions.
Most of these people are female, so it is conceivable that synesthesia is a genetic trait linked to the X chromosome.
In effect, inheriting this trait means disrupting a developmental process in which feelings are "divided" into five different categories.
According to Sitowic, this process of sensory classification begins when the fetus is about 4 months old and does not end completely until adolescence.
More than a year ago, a research article published by Simon Baron-Cohen of the University of Cambridge in the United Kingdom in the journal Nature once again confirmed this argument.
He believes that various sensory abilities are integrated at the beginning and only gradually become separated in the process of growth.
Therefore, to a baby, the mother's voice is likely to have a beautiful color and a warm fragrance.
In some people, however, there are so many connections between the various sensory areas that sensory dissociation does not occur, resulting in synesthesia in adulthood.
In the eyes of outsiders, they are some special "lucky people" who automatically get this feeling, but in fact they don't want to.
For them, the world may look completely different: sounds accompanying visions resemble colorful fireworks, and language and abstract concepts are mixed with colors.
Sitowick explained: "In most cases, the two combined senses are often vision and hearing. For example, a crisp ringing sound may lead to a group of triangles that appear about 15 cm away in front of you; a dog's barking may be related to
A group of moving circles and dots are linked together." This synesthesia occurs because the cortical areas responsible for these sensations are close together: the cortical areas that interpret colors are close to the cortical areas that interpret numbers and sounds.
Synesthesia Questionnaire This questionnaire has seven parts: the first part is about your personal information and contact information; the second part is about the type of synesthesia you may have; the remaining part is about your understanding of Chinese/
Sensory experience of English words.
Please fill in your contact information so that we can ask you some more in-depth questions in the future to help us understand your synesthesia more clearly.
We will not disclose your personal information to anyone else.
Please note that you can decide at any time whether you want to continue answering the questionnaire.
