$\left|\mathrm{\Delta }\mathrm{\Psi }\right|$ and $\left|\mathrm{\Delta }\text{P}\right|$ denote the L₁ norm of quantities defined in Eq. 7. Squares roots were evaluated as this modification yielded a more normal (less right-skewed) distribution of permutation resampling surrogate values (see Figure 7). Red and blue highlight indicate p-values significant at p < 0.05 and p < 0.10, respectively, not corrected for multiple comparisons.
