Fig. 6. Decoding novel tasks using the cognitive factor model.

a A schematic image of the decoding method. Task likelihood was calculated for each target time point using brain activity with hemodynamic temporal delays. The decoding accuracy was examined by a series of binary classifications between the target task (red circle) and the other remaining tasks. b Histogram of task decoding accuracies for all tasks for subject ID01 using a binary classification (Supplementary Fig. 9 shows the other subjects). The red line indicates the chance-level accuracy (50%). Filled bars indicate tasks that were decoded with significant accuracy (mean decoding accuracy, 96.8%; all tasks were significant; one-sided sign test, p < 0.05, FDR-corrected).
