Degus preferentially explore objects introduced in novel positions. (A) Diagram of consecutive sessions in the novel object location experiment. Identical objects are introduced in a familiar environment in positions P1 and P2 in the Sample session and in positions P1 and P3 in the Test session. (B) Percentage of consecutive 30 s windows exploring positions P1 or P2 during the OF1 (grey) and Sample (blue) sessions (Wilcoxon test for difference during first 5 m z: 3.7, p: 2 10–4). (C) Overall exploration time around P1, P2 and P3 (mean ± s.e.m.; color code as in A) during the first 5 min of each session in day 1. Asterisks indicate position explored significantly more or less than others (p < 0.05). (D) As in (C), overall exploration time of positions P1 and P3 during the first 5 min of the Test session across non-consecutive days. P3 was more explored than P1 on day 1 (p: 0.01) but not on the following days.
