Cognitive Workload 8-level arithmetic
EEG Zarr
This dataset contains multimodal recordings from 18 participants performing a mental arithmetic task across eight levels of difficulty, designed to study cognitive workload. It includes 19-channel EEG, ECG, and Pupil Labs eye-tracking (pupillometry) data synchronized via Lab Streaming Layer and converted to BIDS from XDF recordings. Task events encode difficulty ranges based on Q-values, with a 60-second baseline followed by 70 randomized questions.
