*p < 0.05 **p < 0.01 ***p < 0.001. Slope indicates average learning on learning task trials. Time indicates time points 1 through 4 in the learning task. Condition indicates condition of the learning task (coded 0 = threat, 1 = control). Cognitive ability was measured with the Raven’s Advanced Progressive Matrices31.
