Study 1: 80 healthy participants (2 removed) + 5 placebo session from a pilot of the drug study.  Total n=83.  Study 2: 30 healthy participants (3 dropout) in a double-blind drug study.    Total n=27.   Drug was Cabergoline 1.25 mg.   Study 1 subjects had IDs 101-180 and the 5 placebo were 301/401 - 305/405.   Study 2 subjects had IDs 305/405 - 330/430.   The dual numbers were for session:  300s were first session, 400s were second session.  Here we have simply put them in as session 1 and session 2.   So Joe Smith would have been 305 on visit 1, then 405 on visit 2.  If he got cab first we indicated that in the Sess1_Drug column.   EEG published here: 10.1038/ncomms6394.   Task included in Matlab programming language.   Data collected circa 2012-2013 in Laboratory for Neural Computation & Cognition at Brown.  Check the .xls sheet under code folder for more meta data.   Triggers are complicated.  See CC_Triggers.mat under code folder.  A few old analysis scripts are included.  - James F Cavanagh 02/15/2021","recording_modality":["eeg"],"senior_author":"Michael J Frank","sessions":["01","02"],"size_bytes":42423396129,"source":"openneuro","study_design":null,"study_domain":null,"tasks":["SimonConflict"],"timestamps":{"digested_at":"2026-04-22T12:25:34.509843+00:00","dataset_created_at":"2021-02-15T21:02:23.532Z","dataset_modified_at":"2021-02-16T18:03:18.000Z"},"total_files":137,"storage":{"backend":"s3","base":"s3://openneuro.org/ds003518","raw_key":"dataset_description.json","dep_keys":["CHANGES","README","participants.json","participants.tsv"]},"nemar_citation_count":0,"computed_title":"EEG: Simon Conflict w/ Reinforcement + Cabergoline Challenge","nchans_counts":[{"val":64,"count":137}],"sfreq_counts":[{"val":500.0,"count":137}],"stats_computed_at":"2026-04-22T23:16:00.222173+00:00","tags":{"modality":"Visual","pathology":"Healthy","type":"Clinical/Intervention"},"total_duration_s":323595.672,"author_year":"Cavanagh2021_Simon_Conflict","canonical_name":null}}
