Figure 2.
Discrimination performance of intact monkeys (Control) and monkeys with lesions of perirhinal cortex (PRh) on the low feature ambiguity trained pair, and on the two high feature ambiguity pairs. Monkeys were trained on four problems of the type shown in Figure 1, and performance test scores were averaged over the four problems to generate the curves shown here. Asterisks indicate significant differences between the groups; *P < 0.05; **P < 0.01. Data are from Bussey et al. (2003), Experiment 2.
