By contrast, nonmusicians showed a linear N400 learning curve: the N400 mean amplitude increased through exposure reaching a marginally significant increase during the 4th time bin (first time bin: −0.16 μV; 2 nd time bin: −0.04 μV, p = .65; 3 rd time bin: −0.21 μV, p = .85 and 4 th time bin: −0.68 μV, p = .06).
