LDT, log-transformed reaction times of words in the Lexical Decision Test; WM, working memory (z-transformed reading span scores); PTA, z-transformed averaged hearing level (0.5–4 kHz); N = 22 per group; missing values for YNH were replaced by mean values. Significant F changes are shaded, the trend is hatched; significance levels ∗∗∗p ≤ 0.001, ∗∗p ≤ 0.01, ∗p ≥ 0.05.
