  • Residual correlations (i.e., correlations after general target effects are removed from both variables) are only reported for significant main correlations. r, back-transformed average correlation coefficients; T, t values at random-effects group level; VS, ventral striatum.

  • * Significant effects (P < 0.05, one-tailed).
