Correlations between individuals fMRI decoding measures (peak latency and onset latency) and magnitude of the behavioral PRP (RT2 difference between short- and long-SOA dual-task conditions). Hollow dots represent individual data. The red line represents a linear fit and the shaded ribbon represents the standard error. Asterisks indicate significantly postponed T2 decoding peak latencies and onset latencies in the short-SOA dual-task trials (marked by the red vertical line) relative to the single-task trials (marked by the gray vertical line): peak latency, *** p = 3.7 x 10 -6 , N = 26, paired-sample t- test, two-tailed; onset latency, *** p = 9.79 x 10 -5 , N = 26, paired-sample t- test, two-tailed. Note that the raw timecourses in the left panels could only be shifted by multiples of TRs to the nearest SOAs (199 ms and 1393 ms) whereas the curve-fitted data could be shifted by the exact SOAs (300 ms and 1500 ms).
