Applying EMS filtering to test predictions regarding the psychological refractory period. Data presented are for Seen and Unseen trials from the Lag 1 condition sorted according to RT1 and time locked to T2. The spatial filter used in the analysis was computed by subtracting Lag 1 (seen) and Control conditions. Each panel represents trials as a function of time sorted according to the speed of RT1, after using an evolving spatial filter (A), or stationary spatial filters computed at specific latencies: the averaged amplitude between 200–300 ms (B) or 700–900 ms (C) after T2 onset. For subsequent analysis, we refer to these two components as the early and late components, respectively. Previously (Marti et al., 2012) these had been labeled according to their latencies in the lag 9 condition, i.e. M250 and M550. Black dots represent RT1 (small) and RT2 (big). Black lines represent T1 onset (0 ms) and T2 onset (100 ms).
