Fig. 3.

Amplitude tracking results. (a, b) Topographic distribution of channels with significant (different from zero and from chance permutations) amplitude tracking results for each language (purple for French, green for Spanish, orange for English) for the (a) group of 47 newborns, and (b) group of 25 six-month-olds. (c, d) Amplitude tracking results for the three languages at channel Fz, as an illustration. The yellow boxes represent the distributions of the results from the measured EEG data, and the blue boxes represent the distributions of the results from the permuted data, for the (c) newborn group, and (d) 6-month-old group. n.s.: non-significant, * p < 0.05, ** p < 0.01, *** p < 0.001.
