Statistical evaluation of topographic visual field effects of factor 127 (N1) as in Fig. 4, comparing the randomization tests for the full sample (N = 130; 10,000 repetitions) with those for randomly selected subsamples (N = 80, 26 draws; N = 40, 52 draws; N = 20, 108 draws; N = 10, 208 draws; 1000 repetitions each). Shown are for each data transformation the mean factor score difference topographies (i.e., left [] minus right [] hemifield) and corresponding max(t 2 ) topographies thresholded at the 95 th quantile (p = 5). For subsamples, mean T 2 statistics were evaluated with the cumulative randomization distribution resulting from the product of draws and repetitions.
