Permutation-controlled t-tests on time-varying ssVEP amplitude differences between the CS+ and the CS− condition in each experimental block (habituation, acquisition, and extinction). Significance thresholds of the amplitude difference were determined for each block separately, at each time point and each scalp location (e.g., sensor 125). Applying a significance level of .05 (two-tailed), the conditioning-induced amplitude difference was statistically significant only during the acquisition block, depicted as the gray square.
