Table 1.
MANOVA results for the EEG graph indices, degree, density, and strength. In the first column, the factors indicated were: (MNM for comparisons between musician (M) vs non-musicians (NM) groups, FB for repeated comparisons between frequency bands, TAN for those corresponding to the different auditions [tonal (T), atonal (A) and noise (N)], and FB * TAN for cross-interactions; in successive columns, appear the test used (W-R or L-B); the F statistic, the degrees of freedom (DF), and the level of significance P; in the last column (Comp.) with asterisks * the significance levels of the a posteriori comparisons between pairs of repeated factors are indicated (** for p < 0.01, and *** for p < 0.001).
