Your data will be transferred to a secure UK-based server managed by the University of Oxford. Information which could be used to identify you will only be accessible to approved members of the research team, and unless you agree otherwise, will be deleted at the end of the study. When we share the findings of GameChanger with the wider scientific community, any information which could be used to identify you will be removed.

This study has been carefully reviewed by the University of Oxford Central University Research Ethics Committee (CUREC), who specialise in ensuring that research is safe and properly managed.

Some of the tasks in this app will ask you to provide short spoken responses. To do this we will need to record your voice. We will then analyse both what was said, and how it was said. It will be clear which tasks involve voice recording and we will delete your voice recordings once our analyses are complete.

We would like you to complete another month of daily smartphone tasks after you have been in GameChanger for one year, and again after two years. We will send you invitation by email when your next round of tasks are ready to begin. Follow the steps in your email invitation to start playing. Alternatively, you can sign up by completing this form. Please use the same email address as when you joined in year one. As with any part of this study, you can choose to stop participating at any time.

You can help us to understand what healthy cognition looks like. We will combine your data with other participants of the study so that we can publish papers that will help to inform the scientific community. We will put details of any publications or other findings in our blog. Use the form below to opt-in, if you would like to receive an email each time a new article is available (you can unsubscribe at anytime).

If you are a participant in a UK research project such as the Children of the 90’s or Generation Scotland, we may be able to link your GameChanger performance with information you have provided previously. Combining data like this can massively increase the value of your contribution. To make this link, we may share your personal information (email address, date of birth, postcode) with partnered research projects, or send you an additional email. If you think you have previously participated in research, and would be willing to allow us to do this, please indicate on the form below.
