q3 · i3 · associational · r2

Correlational analysis of mean voxel activation in the early stress group found "ACC activation during reward trials was positively associated with reversal learning performance" (Table 4 reports r = .517, p < .05); no significant associations emerged among controls.

"among stress-exposed adolescents, ACC activation during reward trials was positively associated with reversal learning performance"
