Figure 4. Decoding perception, action, intention, and accuracy for conscious and nonconscious trials according to SOA. Multivariate decoding was applied either to each time sample (central columns) or to the full trial time window (right columns), and results were spited by SOA condition. Results demonstrate that the required response and the accuracy could be decoded in conscious conditions for each SOA condition. A, B, D, E, G, H, J, K, Central columns, AUC, a measure of decoding accuracy, is plotted for each SOA condition after averaging across subjects, aligned on stimulus onset, separately for the stimulus position decoder (top vs bottom, A, B), actual response decoder (left vs right, D, E), required response decoder (left vs right, G, H), and accuracy decoder (error vs correct, J, K). Due to reduced trial numbers, only the shortest SOAs (16, 33, and 50 ms) are presented for unseen trials (B, E, H, K), while only longer SOAs (33, 50, 66, and 100 ms) are included for seen trials (A, D, G, J). Bars below each graph indicate, for each time point, the number of subjects presenting an above-chance classification score at that instant as computed by cluster analysis. C, F, I, L, Right column, For each subject and each SOA condition, individual measures of AUC are plotted for seen (left) and unseen (right) trials, separately for the stimulus position decoder (C), actual response decoder (F), required response decoder (I), and accuracy decoder (L). In each case, decoding was applied on all the sensors and time points from the full trial time window (0–800 ms after stimulus presentation), and results were then split according to SOA condition.
