Performance (mean percent correct ± s.e.m.) of control rats and rats with hippocampal lesions on recognition for each of the different types of probes. ‘X’ designates a randomly selected odor that was not presented in the series and used as the alternative choice. Control rats and rats with hippocampal lesions performed equally well on odor recognition (repeated-measures ANOVA, F1,12 = 0.328, P = 0.577). In addition, recognition scores were higher for more recently presented items (main effect of probe type, F4,48 = 4.778, P = 0.003), and there was no significant difference between groups in the effect of item recency (Group × Probe interaction, F4,48 = 0.664, P = 0.620).
