Figure 4.

Results from all seven tests for all four groups of participants averaged across the three test sessions (CON, five controls; ENC, three amnesic patients with large medial temporal lobe lesions due to encephalitis; H, three amnesic patients with damage limited to the hippocampal formation; and KOR, three amnesic patients with diencephalic damage due to Korsakoff's syndrome). None of the amnesic groups were impaired relative to controls on any test. Average scores for individual participants are shown (black dots) along with the standard error of the mean for each group (error bars). The tests are ordered according to how difficult they were for the controls (CON).
