Decoder accuracy changes as a function of tolerance for discrepancies in time. (a) Illustration of onset detection accuracy calculation. Onset detection accuracy was calculated as a function of tolerance time window length around true onset. Predicted onsets were defined as a positive crossing of the probability above threshold. (b) Illustration of varying the tolerance window around true onset to calculate the onset detection accuracy. Tolerance window was varied from 0 to 3 s. True positives were considered any predicted onsets within the window, and true negatives were the absence of an onset prediction within rest. (c) Onset detection accuracy plotted as a function of tolerance time window around true onset and averaged across participants for all conditions. The point of comparison across conditions (0.8 s) is denoted by a vertical dotted line
