Information and consent

Online studies in perception, learning and decision-making

Welcome to the experiment. Before taking part, it is important that we receive informed consent from each participant before they begin. Before signing this form, make sure that you carefully read the study details below.

What is the purpose of this study?

We are interested in how the adult brain controls learning and decision-making. This research aims to provide insights into how the healthy brain works to help us understand the causes of a number of different medical conditions.

Who is conducting this research study?

This research is being conducted by the Wellcome Centre for Human Neuroimaging and the Max Planck UCL Centre for Computational Psychiatry and Ageing Research. The lead researcher for this project is Dr Jessica McFadyen (j.mcfadyen@ucl.ac.uk). This study has been approved by the UCL Research Ethics Committee (project ID number 9929/002) and funded by the Wellcome Trust.

Who can participate in the study?

We are recruiting participants aged between 18 and 40 years old who spoke English as a first language.

What will happen to me if I take part?

You will play an online computer game, which will last up to 90 minutes. We ask that you only participate in this experiment if you have time to complete the entire experiment. You will receive £5 for participating but you can receive a BONUS £5 by finishing the game and performing well.

You will also be asked some questions about yourself, your feelings, background, attitudes, and behaviour in your everyday life.

Remember, you are free to withdraw at any time (and you don't need to provide a reason).

What are the possible disadvantages and risks of taking part?

You will be asked to answer some questions about mood and feelings, and we can provide information about ways to seek help should you feel affected by the issues raised by these questions.

What are the possible benefits of taking part?

While there are no immediate benefits to taking part, your participation in this research will help us understand how people make decisions and this could have benefits for our understanding of mental health problems.

To help future research and make the best use of the research data you have given us (such as answers to questionnaires) we may keep your research data indefinitely and share these. The data we collect will be shared and held as follows:

The legal basis used to process your personal data will be the provision of public task (this means that the research you are taking part in is deemed to be in the public interest). We will follow the UCL and legal guidelines to safeguard your data.
