The Synesthesia Battery
Speed Congruency Test




This test cannot go on as there is not much variability in the colors





Thank you for completing the first of the tests we have designed for grapheme-color synesthesia. You will now begin another short test based on your responses on the previous test

Once you begin, you will see on the screen a number or a letter flash for one second and then vanish. Each grapheme will appear in a color as indicated by your color choice on the previous test or a color different from what you indicated. If the grapheme matches your synesthetic color, click "It Matched", otherwise click "It Didn't Match".


Please respond as fast as possible for each grapheme. You will now be presented with a maximum of 72 trials and the test should take about 2 minutes to complete. Please click the button to begin.
