ISD decreases the preference for LR choices in low impulsive (LI) animals across sessions. (a) LR choices comparing control and stress groups at each delay for LR (1 s, 10 s and 20 s) and across sessions. Stressed animals showed significant decreases in LR choices at 10 s delay, S1 [F_(1,10) = 9.02, p = 0.013, η_p² = 0.47] and S3 [F_(1,10) = 5.04, p = 0.049, η_p² = 0.33], and 20 s delay, S1 [F_(1,10) = 6.05, p = 0.034, η_p² = 0.37], S2 [F_(1,10) = 8.47, p = 0.016, η_p² = 0.45] and 2w [F_(1,10) = 5.09, p = 0.048, η_p² = 0.33]. (b) SR choices comparing Control and Stress groups at each delay for LR and across sessions. Stressed animals showed significant increases in SR choices at 10 s delay, S4 [F_(1,10) = 6.53, p = 0.029, η_p² = 0.39], and 20 s delay, 2w [F_(1,10) = 5.54, p = 0.040, η_p² = 0.35)]. Data represents the mean ± SEM. *p < 0.05 compared to Control after planned comparisons.
