Regression DV: SWM performance (as indexed by total error Z-score; higher Z-score = fewer errors)

Variables	Unstandardized regression coefficients, SE, p value
Pubertal stage	B = 0.1, SE = 0.097, p = 0.308
Right middle temporal gyrus	B = 0.720, SE = 0.732, p = 0.332
Right parietal white matter	B = 0.440, SE = 1.03, p = 0.671
Prefrontal gray matter (near the left anterior cingulate)	B = 1.410, SE = 0.490, p = 0.007
Right prefrontal white matter	B = 2.556, SE = 1.110, p = 0.026
