VerbalWorkingMemory

raw EEG in a modified Sternberg working memory paradigm with two types of task: with mental manipulations (alphabetization) and simple retention (TASK) and 3 levels of load: 5, 6, or 7 letter to memorize (LOAD).

Events.tsv files in eeg folders contain event descriptions (see column trial_type).
