Synesthesia-Ideasthesia

Synesthesia, a neurological condition when one sensory leads the other sensory to something and people who has the experiences are known as synesthetes. There is a common form of synesthesia called color-graphemic synesthesia which letters or numbers are seen as colored. There is also another form of synesthesia called chromesthesia where sounds can also be seen as colored. It is said that loud tones are brighter than soft tones, and lower tones are darker than higher tones.

Ideasthesia, defined as sensing concepts or ideas. One common example of ideasthesia is when letters of the alphabet are associated with colors and determined by the meaning. For example, ‘1’ can be meant as ‘I’, ‘3’ as ‘E’, ‘4’ as ‘A’, etc. depending on the presented context.

Both synesthesia and ideasthesia are sometimes considered as disability. Synesthetes thought letters or numbers have a personality and it make them bad at math because synesthetes don’t want to expose a number by substract, adding, dividing, or multiplying ‘nice’ numbers to ‘bad’ numbers. On the other hand, if a synesthetes suffers in ear infection, it will be difficult for them to hear or understand what is happening in the world.
