Mean accuracies of simple SVM classifiers.

	Original EEG	EEG with random correction	EEG with artifact correction
All trials	0.3	0.31	0.33
Rejected trials	0.23	0.23	0.29

A simple t-test confirmed that all accuracies were significantly above chance level (1/6 for six different colors) at a p = 0.05 level. Original EEG: The Original EEG data. EEG with Random Correction: The EEG data after random artifact free trials were “corrected.” EEG with artifact correction: The data after we applied the EEG artifact correction on the trials that were marked as artifact ridden.
