Experiment 2. Measures of eye movements in memory-impaired patients and controls in response to repeated scenes (black bars) and novel scenes (white bars) when participants simply viewed the scenes and had no expectation of memory testing. In each of 10 test sessions, participants viewed 20 scenes and then viewed 20 repeated scenes intermixed with 20 novel scenes (total = 400 scenes). Both patients and controls made fewer fixations (A), sampled fewer regions (B), and made longer fixations (C) for repeated scenes than for novel scenes (i.e., both groups exhibited the repetition effect). Asterisks indicate differential viewing of novel and repeated scenes (Ps < 0.05; †Ps < 0.09). MTL = 5 patients with medial temporal lobe lesions; CON = 6 controls. Error bars indicate standard error of the difference between the scores for novel and repeated scenes that was used to test for the repetition effect.
