Welcome to the Synesthesia Project research site. On these pages, you will find more information about synesthesia, the Vision and Cognition lab, and our ongoing research with color-graphemic synesthetes. You will also have the opportunity to participate in two of our web-based experiments, available to both synesthetes and non-synesthetes.

What is synesthesia?

From the Synesthesia FAQ: Synesthesia (or synaesthesia) is loosely defined as "senses coming together," which is just a translation of the Greek (etymology: syn - together, esthesia from aesthesis - sensation). At its simplest level, synesthesia means that when a certain sense or part of a sense is activated, another unrelated sense or part of a sense is activated concurrently. For example, when someone hears a sound, he or she immediately sees a color or shape in his or her "mind's eye." People that have synesthesia are called synesthetes.

How can I participate in synesthesia research?

• If you are interested in participating in synesthesia research online, visit our experiments page to learn more about which batteries the Synesthesia Project has available. Even if you are not a synesthete, you can still provide helpful data to synesthesia researchers.
• If you are interested in participating in research and are in the Boston area, visit our laboratory information page to see for which experiments the Synesthesia Project is currently recruiting.
