And here are the significant correlations

WISC_FSIQ
DMN: y = -15.09x + 104.13, r = -0.09, p = 0.0247
FPN+DMN: y = -13.05x + 102.95, r = -0.08, p = 0.0413
---
WISC_BD_Scaled
DMN: y = -3.78x + 10.60, r = -0.12, p = 0.0051
FPN+DMN: y = -4.37x + 10.46, r = -0.14, p = 0.0007
---
WISC_VP_Scaled
FPN+DMN: y = -2.80x + 11.22, r = -0.09, p = 0.0231

Corrected using Bonferroni, where p = 0.05 / 10 = 0.005, leaves only one significant correlation: the one between BD_Scaled and FPN+DMN.
