  1. In the encoding session in which two identical objects were presented, time spent with object placed on the left and on the right (placed at “L” and “R” in Figure 3, respectively) are shown. In the retrieval session, time spent with the familiar object and the novel object are shown regardless of its location. Data are presented as means ± SEM. Asterisks indicate a statistically significant prolonged search time compared to its counterparts (paired t-test, p < 0.05; Cohen’s d > 0.80).
