2.2 Procedure
Participants underwent two sessions, each including 2.5 hours that were divided as follows - 1.5 hours of EEG tasks, then 1 hour of behavioral testing with a 10-15 minute break between the EEG and behavioral testing. Participants were prepared for the EEG recording by two research assistants. Participants underwent a 3-minute artifact training period, then performed three separate ERP paradigms (a novelty odd-ball, a speeded visual flanker task, and a visually-evoked contingent negative variation, CNV) in an electrically shielded, sound attenuated recording room. Only the data from the speeded visual flanker task will be presented here. Procedures for this study were approved by the University’s human research committee. Written informed consent was obtained from all participants.
