TANOVA, average topographies, t-maps and microstate analyses of the NoGo condition in the sport-specific Go/NoGo task. (A) The curve represents the p-values from the TANOVA plotted for each time point from 0 to 800 ms after stimulus onset. The period of significant topographic differences (p < .05) is highlighted in pink. (B) Mean ERP topographies were computed for each group separately over 100 ms time intervals. The topographies were normalized (GFP = 1). Red and blue indicate positive and negative potential values, respectively. The t-map contrasting each group with the other groups is shown for the POI. Positive (in red) and negative (in blue) t-values indicate more positive and more negative potentials regarding the order of the group contrast (T-E indicates that the data from the table tennis group were compared to the data from the endurance group). The p-values from the TANOVA of the t-maps are displayed. (C) The topographies of the three microstate maps obtained from the cross-validation procedure and their duration are displayed for the three groups. Red and blue indicate positive and negative potential values, respectively. The topographies were normalized (GFP = 1). The colored frame surrounding each map corresponds to their occurrence in the graph below. (D) The GFP of the microstate maps is displayed as a function of time for each group. B = basketball; T = Table tennis; E = endurance. The topographies displayed in (A), (B) and (C) have been generated via MATLAB (http://www.mathworks.com/).
