How to get access?
Between 2019 and 2024, we have tested over 900 individuals in their thirties, who have collectively spent over 500,000 hours on tests and tasks. On December 30, 2023, the last testing day took place. Data collection in the lab, at home, and online has been very successful. In total, we conducted more than 2300 testing days and include over 700 complete datasets. Additionally, around 300 participants collected partial data. All researchers of Radboud University, Radboudumc, and the MPI for Psycholinguistics are eligible to request data.
