Brucella detection accuracy across training phases. Average percentage of Brucella-positive target samples correctly indicated (hit) and false positives (incorrect indications on Brucella-negative samples) across all training phases beginning with Phase II (post-indication training). Error bars represent the standard error of the mean (SEM). Rats advanced to Phase IIIa (10-hole discrimination with 30 total samples) on Session 10. New Brucella-positive samples (7 + and 12+) were introduced on Session 15. New non-target (E. coli) samples were added during Session 28. Sessions 51 and 52 depict the two Baseline refresh training sessions of Experiment 2
