What is synesthesia? Stimulation of one sense leads to an automatic experience in a different sense. ~4% of people are synesthetes (18% w/ Autism spectrum)
Who first introduced synesthesia? George Tobias Ludwig Sachs
Describe Sound-Color synesthesia The sound of graphemes & phonemes can be perceived as colored shapes
Describe Number-Form synesthesia Number maps are created in the minds of synesthetes. Basically, when they think about numbers, this number map is involuntarily visualized.
