Thank you for your interest in our research study!

We are investigating the effect that dyslexia has on performance in our online ability tests. You will be asked to complete two tests (Numerical Reasoning and Deductive Reasoning) and some survey questions asking for details about your experience with dyslexia and for feedback on the tests.

The tests you are asked to take may be difficult for you. Everyone will find different bits hard and we would just like you to try your best. If the way the test questions look and the way they are presented make the tests more difficult for you, please let us know in the survey questions after you have taken the test. Unfortunately we cannot provide adjustments for this study as we want to know how people with dyslexia are affected if adjustments are not used.

We are working on new technology to make sure that our tests in the future are much more accessible for people with dyslexia and other disabilities. Your feedback is very important in helping us do this!

Please Note: We are inviting only individuals aged 18 and over and who have dyslexia to participate at this time. In order to participate you will need to register on our system. Total time required will be an hour. If, after registering, you wish to complete the study at a later date, please note down your session ID as you will need this to log back in.
