Figure 3. Partner preference test.

(A) Representative figure showing the design of the arena in which voles were tested for partner preference test. (B) Between 48 and 72 hr of cohabitation, partner preference was evaluated on each subject (N = 32). Partner preference index revealed a significant difference between the time spent on the incentive area related to the partner, with the incentive area related to the stranger vole. Boxplot graphs show whiskers with 10–90 percentiles; horizontal line inside the box shows data median, and ‘+’ represents data mean. (*) denotes significance at p<0.05.

No significant differences were found between Partner preference indexes obtained 48 hr after the onset of cohabitation (N = 16) in male (n = 7) and female (n = 9) prairie voles, with Partner preference Indexes obtained 72 hr after the onset of cohabitation in male (n = 9) and female (n = 7) voles.
