Figure 3. Timelines of the averaged accuracies (averaged Fisher-Z normalized correlation) of the prediction of subjects' single trial reaction times.

Different low-pass cutoff frequencies were chosen during the preprocessing (0.1 Hz, 0.15 Hz, 0.2 Hz, 0.25 Hz, and 0.3 Hz). Decoding performance on low-pass filtered data with cutoff frequencies between 0.15 Hz and 0.3 Hz is very similar. When the data are low-pass filtered with a cutoff frequency of 0.1 Hz decoding performance declines.
