Table 2 Formula and statistical results from the mixed model analysis of reaction times in the subsets with high (left) and low (right) semantic discrimination (d′). P-values are computed via Wald-statistics approximation and significant p-values are shown in bold.

From: Semantic discrimination impacts tDCS modulation of verb processing
