Figure 3

Test-retest reliability. Rats tested for Figure 1 were re-tested as indicated in Methods. (A) Rats exhibit similar behavior in the 5th block of each session during the first and second time they are tested in the task (N=17, delay × retest interaction, p=0.47) (B) When the full session is examined, rats exhibited a small but significant shift in preference for the delayed reward from test to retest. (delay × retest interaction, p=0.0017). However, pairwise comparisons yielded no significant differences when the Bonferroni correction was applied (test vs. retest at each delay length, all p’s >0.05.
