Group-level experimental effects during the post-learning manipulations.

<p>Summary of the mean activation strengths for native and foreign language during each of the tasks (<i>left</i>; repetition in the learning phase, 1-back control task, recognition) and noise levels (<i>right</i>; SNR +70 dB (no noise), +10 dB, 0 dB) in the left temporal and bilateral frontal sources. The time windows are the ones that showed learning effects during the initial learning phase. Statistically significant main effects of stimulus familiarity across experimental conditions (tasks / noise levels) and languages in the ANOVAs are denoted as text beside each plot (“new fam”, p < 0.05). Asterisks (*) below the text denote statistically significant interactions of stimulus familiarity and task / noise level.
