Nf1^+/− mice exhibit increased impulsive choice in the delay discounting test (DDT). Graphs illustrate a the general methods used in the DDT on a t-maze and the effects of Nf1^+/− on b the number of small reinforcements chosen during a DDT task in a t-maze and c the number of days the mice took to reach criterion prior to the initiation of the delay. *p < 0.05 compared to wild-type (WT). #p < 0.05 compared to 0 delay within the same genotype. All data reported as mean + S.E.M
