In October 2004 , I participated in a web-based synesthesia study conducted by Waterloo Synaesthesia Research Centre at University of Waterloo in Ontario Canada.

The study shows participants a set of letters and asks them to choose colors corresponding to the letters and numbers. The entire alphabet and set of digits is repeated. Afterwards, users are asked to rank their degree of
confidence in their color selections.

Here is a link to the study... section two has the color test.

Here is the email message confirming my grapmeme-color synesthesia for letters and digits.

** I was very excited to recieve this email... I did reply to him with a link to my midi viz application, and other research available at http://www.elchill.com/ **

Dear Lew,

Thank you for completing both the SYNAESTHESIA SURVEY and the COLOR ASSESSMENT TEST on the Synaesthesia Rsearch Centre website.

Your performance on the color assessment test indicates that you definitely have grapheme-color synaesthesia for letters and digits.

As you may have guessed while you were completing the test, we were interested in establishing how similar the colors that you selected in Part 1 for each letter and digit where to the colors you selected in Part 2.

People who have grapheme-color synaesthesia select very
similar colors for each letter and digit in the two parts of the test, whereas people who do not have synaesthesia tend to select very different colors.

Your results indicate that there was considerable consitency between the colors you select for the letters and digits in Part 1 and Part 2 of the test. Thus, the results indicate that you have grapheme-color synaesthesia.

If you have any questions regarding our studies of synaesthesia, please feel free to contact me.

Best wishes,
