We are a public research group headed by Prof. Cardoso-Leite at the University of Luxembourg. Our goal is to better understand how the human mind works. More specifically, we are interested in cognitive abilities (such as attention or learning), their interrelationships, how they vary with variables of interest (e.g., age, gender or personality) and how they might be improved with training.
This is why we are continuously developing game-like tasks and questionnaires that we invite you to complete within our online/mobile application called “Mathemarmite”. Mathemarmite is an application of the University of Luxembourg.
By participating in this project, you will provide valuable data for science. The goal of Mathemarmite is to better understand the human mind in general and not to make any claims about a specific user of Mathemarmite. We hope you will have fun participating in this study but we do not claim you will get any direct benefit from participating. We do not expect any negative effects for you either. Hopefully, you will just have fun.
- We will not sell any of your data to anyone;
- We will not share your personal data (unless legally obliged);
- We treat your data with confidentiality;
- Only anonymized data may be shared openly.
Data Collection. We will collect data about your performance in our games and questionnaires. That data will be associated to an arbitrary code (e.g., bx#2245) and will not contain any personal data (e.g., your actual full name, address). To our best knowledge, it is close to impossible to recover a person’s identity from that data.
If you agree, you can provide limited additional information that is directly relevant to the research project. This includes the gender, month and year of birth and country of residence of the user (but NOT your full name or address). This type of data can be useful for research because they are strong predictors of performance in this type of activity but is not sufficient to identify a person. The first name you may provide when creating a profile for the game will not be stored or accessible outside the user’s device.
All collected data is secured with industry-standard encryption, so that unauthorized parties can never read it. We will not sell any data to any third party. If you are asked questions you do not want to answer, please feel free not to.
Use of data.
For the purpose of running this study we might need to store additional information such as device properties, software platform version, browser (e.g. “Chrome”), the date and time you accessed Mathemarmite. This data is necessary for the performance and the maintenance of the tools. This type of information may help us for example to debug software issues that are specific to a device.
In the spirit of open-science we ask you to agree to make your anonymised data public and freely accessible. Making data public is important because it allows other researchers to replicate our analyses and possibly challenge or confirm our conclusions. It may also allow other researchers to attempt interesting analyses we did not think of.
Also, in the spirit of open-science, the results of our research that are based on your data will be freely accessible online (via pre-prints, open-access articles, or other forms). This way you can see for yourselves how and what your data is used for.
Use by Children.
The use of Mathemarmite by minors under 16 years old needs to be done under the control of a parent or legal guardian
We might occasionally communicate with you if we believe those communications to be relevant regarding your participation in this research. We will however not exploit your participation to send you advertisement or marketing messages. Communications may take the form of app notifications on your device. You can turn off these notifications in the app options.
Term and Termination.
If you do not want to participate any longer in this study, you can simply stop using the app and uninstall it. Be aware that uninstalling the app will delete all progress you have made in the game.
Although we do not use browser cookies, we may store cookie-like data on your device for technical reasons. This data is required to be stored on your device for the game and our study to work and cannot be used to track you on the web like other cookies.
