(A) (top) Trial outcomes in the 5-CSRTT. (bottom) Timeline of individual trials in the 5-CSRTT. Arrows indicate nose poke response. P, premature; C, correct; I, incorrect; O, omission. (B) Progression of mice in 5-CSRTT training. (C) In a test of attention at early and late training phases of the 5-CSRTT, percentage of correct, and omission trials varied by cue duration. (D) In a test of impulsivity at early and late training phases of the 5-CSRTT, the percentage of premature, correct, and incorrect trials varied by inter-trial interval (ITI) duration. n = 16 mice (8 female, 8 male).*p<0.05 for the indicated main effect or interaction.
