Synesthesia types described in the research literature. Original self-report items; no consistency task, so it cannot confirm synesthesia.
- Whether letters, numbers or words come with a color of their own
- Whether music, voices or everyday sounds arrive with colors, shapes or movement
- Whether months, days or numbers sit in a fixed place in the space around you
- Whether letters, numbers or days seem to have a personality, a mood or a gender
Synesthesia is a trait in which one sense or idea automatically triggers another. Common examples are letters or numbers that have colors, music that comes with shapes or colors, and months or days laid out in a fixed place in space. The experiences are involuntary and stay the same over time, which is what separates them from imagination or from associations you learned.
Not on its own. A questionnaire can only capture what you report. Researchers confirm synesthesia by checking that your associations stay the same when you are retested weeks later, and that check cannot be done in a short quiz. This test tells you whether your experiences look like the kind worth checking and shows you how to run a simple version of that check yourself.
It covers five families: letters, numbers and words that come with colors; sounds that come with colors or shapes; sequences such as months, numbers and days that sit in a fixed layout in space; letters, numbers and days that come with a personality; and words, sights or textures that bring taste, touch or other body sensations. Each has three questions, and you see which family your answers fit best.
It is described as a trait, not a disorder, and many people who have it describe it as neutral or enjoyable. This test is not a diagnosis and cannot tell you whether anything is wrong. If your experiences are distressing, painful or began suddenly, for example after an injury, an illness or a new medication, talk to a doctor.
