Do you see numbers associated with colours?
Do you have experiences like:

3 + 4 = 7?

If you indicated yes to these questions, then we invite you to participate in a study exploring whether the use of a personalized calculator device with digits matched to their colours will change your speed, accuracy, and affect.

You may be eligible to take part if you:

• Have consistent number-colour associations.
• Have normal vision or vision corrected to normal (i.e. by glasses or contact lenses)
• Can attend the University of Sydney for testing
• Are willing to undergo everyday mathematical tasks using a calculator

You will be reimbursed for your time, transportation, parking and reasonable out of pocket costs according to the guidelines in our Participant Information Statement.

If you are unsure if your number-colour associations are consistent, you can find out via the test available at the following URL http://www.synesthete.org/.
Please note: if you wish to avoid repeating this test at the university, you may forward us your results by providing the email jber8397@uni.sydney.edu.au as the researchers’ address.

If you are interested in participating or would like to know more about the study email Joshua Berger at jber8397 at uni.sydney.edu.au.
