Albrecht, Matthew; Waltz, Jim; Cavanagh, Jim; Frank, Michael; Gold, Jim

This is the EEG dataset part 1 of 2 as well as the trial-by-trial behavioural data for the paper "Reduction of Pavlovian bias in schizophrenia" under submission at PLoS One.

EEG data contains the cleaned, ICA eye-blink corrected data in EEGLAB format. Also included is an ICA decomposition using the AMICA algorithm.

Triggers: Triggers are also included in the behavioural R data file "BehaviouralData&M6Fits.RData" as a data.table (will need the 'data.table' package in R) named "dftr". Model fits are in the R data file, also as a data.table, labelled dfM3.

Stimulus onset codes are: 1 & 101 = Go-to-Avoid; 2 & 202 = Go-to-Win; 3 & 303 = NoGo-to-Avoid; 4 & 104 = NoGo-to-Win. (with 100s as invalid stimuli, or requiring the opposite response based on the contingency)

Feedback onset codes are as follows: 21, 121, 41, 141 = win (thumbs up); 29, 129, 9, 109 = lose (thumbs down); 20, 120, 40, 140, 30, 130, 10, 110 = no change (horizontal thumb).

Response onset codes are: 301, 302, 303, 304 for a response to a 'valid' stimulus (not necessarily correct - refers to contingency); 401, 402, 403, 404 for a response to an invalid stimulus.

Hope you enjoy!
