Group-averaged classification accuracy time series in the single-task and dual-task trials in ( a ) auditory cortex. The upper graphs in each panel show the results for the short SOA conditions and the lower graphs for the long SOA conditions. The left columns show the raw decoding results and the right columns show the fitted curves of the decoding data. Blue lines show task-specific decoding results for T1 in the dual-task conditions and red lines show task-specific decoding results for T2 in the dual-task conditions. Green lines show AO-specific decoding for the single AO task in ( a ) auditory cortex and yellow lines show VM-specific decoding for the single VM task in ( b ) manual motor cortex. Dashed gray lines represent chance levels (12.5%). Vertical dashed lines indicate onset/peak latencies in single-task and dual-task trials. Asterisks indicate significantly earlier T1 decoding peak latency in the short-SOA dual-task trials (marked by the blue vertical line) relative to the single-task trials (marked by the green vertical line) in ( a ) auditory cortex (** p = 0.0013, N = 26, paired-sample t- test, two-tailed), and significantly postponed T2 decoding peak/onset latency in the short-SOA dual-task trials (marked by the red vertical line) relative to the single-task trials (marked by the yellow vertical line) in ( b ) manual-motor cortex (peak latency, *** p = 1.6 x 10 -4 , N = 26, paired-sample t- test, two-tailed; onset latency, *** p = 7.8 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).
