However, for L2 listeners, the interaction between attention and linguistic structures reached marginal significance ( F (1.387,31.893) = 3.692, p = 0.051), showing that only at the phrase-level frequency of 2 Hz did L2 listeners take advantage of voluntary attention to enhance their neural responses compared with passive listening ( p = 0.029) but not at the other tagged frequencies.
