Welcome

Welcome to this experiment conducted by Frauke Stehr, a researcher at Maastricht University. In the experiment you will be able to earn money based on the choices you make. You will earn a fixed participation fee of {{ session.config.participation_fee }} for completing the study. Depending on your choices in the experiment, you may earn substantially more. We have calibrated the payments so that participants who finish the experiment earn at least £2.95, and £4.35 on average. Your precise payments can, however, be larger or smaller depending on your decisions during the experiment.

The experiment will take an average of 35 minutes. It is important to note that we apply a strict "no-deception" rule, meaning that everything we write is true and implemented exactly as described. The experiment was ethically approved by the Ethical Review Committee of Inner-City Faculties of Maastricht University.

Your Data

What information do we collect and why?

Upon your consent, we collect responses to the experiment you provide. No individual can be personally identified from the collection of this data. The data is anonymous, with the exception of your Prolific ID, which is required to administer payments. The researcher does not have access to any other personal data and therefore cannot link this ID with any other personal data. After the payment has been processed, we will separate the Prolific IDs from the dataset and thereby anonymise it. The Prolific IDs will be stored separately and safely on a Maastricht University server. After this anonymisation, it will not be possible to identify participants based on their responses.

The data collected in this experiment will be used for academic research in behavioural economics. We will publish the results in academic papers. These papers will contain only anonymous data presented as tables and figures (e.g., percentages and averages).

Cookies policy

We do not use cookies. We do store some technical information (e.g., your screen resolution) automatically to be able to analyse technical problems.

What is the legal basis for holding these data?

The lawful basis for processing this information is Article 6(1.e) of the General Data Protection Regulation (GDPR): processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.

Your data will not be used for other purposes. Only fully anonymised data will be shared for the sole purpose of replicating the analysis if requested by scientific journals. You have the right to request access to your data and/or deletion of your Prolific ID from our data by sending an email to f.stehr@maastrichtuniversity.nl.

How do we store the data?

The study uses the app oTree, which is hosted on the servers of Heroku, a cloud platform based in San Francisco (USA) and owned by Salesforce. To send emails to you the study uses the services of Academic Prolific. These companies declare to be compliant with the GDPR. No personal data other than your Prolific ID will be shared with these companies. Your Prolific ID is stored encrypted in the Heroku cloud database and cannot be read by anyone outside the research team. All raw data collected in the experiments is stored securely on servers at Maastricht University. Maastricht University stores all data for at least 10 years. After that, the data is destroyed or transferred to other media for longer storage if needed.

The faculty's Privacy Officer is Eric Soemers. For questions or complaints about the privacy legislation of this research you can contact him at SBE Administration Office – IT and Facilities, via h.soemers@maastrichtuniversity.nl.

Your consent to participate

I hereby give permission for my data to be used for scientific purposes. I have had enough time to decide whether I want to participate in the experiment. I know that participation is voluntary and I know that I can decide to withdraw from the experiment at any time. I do not have to justify such a decision to withdraw. If I withdraw I will forfeit any payments.

I understand that the data will be stored anonymously and thus can only be published anonymously. I give permission for the researcher to use my anonymised responses in subsequent experiments.

I understand that for people with photosensitivity, the characteristics of some of the images in the experiment may cause dizziness or other symptoms.

Before you begin, please turn off your phone/e-mails/music so that you can concentrate on this experiment. Thank you!
