Welcome and thank you for participating!

We are conducting a research study on uncertainty visualizations for EEG/ERP topographic maps. The goal is to evaluate which visualization techniques best support users in interpreting uncertain brain activity patterns.

Your responses will help improve newly developed visualization methods for neuroscience research and clinical applications.

This study is anonymous and voluntary. There are no known risks, and you may withdraw at any time. 

The questionnaire takes approximately 15–30 minutes and includes visual interpretation tasks and short opinion questions. 

  • We ask you to perform two tasks and will measure reaction time and accuracy. That's why you may not return to previous pages. 

  • Each task includes 21 trials. In Task 1, all trials will be shown together on a single page. In Task 2, each trial will be shown on a separate page.

  • For best results, please use a desktop or laptop computer. 

 Thank you for contributing to this research.
