Neurocognitive mechanisms of individual differences in cognition: a behavioral performance and EEG dataset

The Mainz Network Study provides comprehensive behavioral and multimodal neural data from 215 healthy adults aged 18 to 40 years from the general population, supporting research on interindividual differences in cognitive ability. Across three sessions, participants completed the Berlin Intelligence Structure Test and Raven's Advanced Progressive Matrices (general and fluid intelligence), three binding tasks and three complex span tasks (working memory capacity), a cued task-switching paradigm (cognitive control), and three elementary cognitive tasks indexing processing speed (Posner letter matching, Sternberg memory scanning, two-choice reaction time). Electroencephalography (EEG) data and magnetic resonance imaging (MRI) data were collected. Here, we describe and publish the behavioral data (reaction times and accuracies) as well as EEG data recorded during cognitive control and processing speed tasks and during resting-state. Behavioral and EEG data are freely accessible via a RDC-ZPID repository. All data are BIDS-organized and shared raw.
