N=16 sessions across n=3 unique groups of 7 mice., Graphic depicting a dynamic non-social context control where inanimate totems were pulled from the staging area until the entrance point of the reward zone using an automated retractor while one mouse foraged for a food pellet .
=0.68, p=0.67; two-way RM-ANOVA) on the animals’ latency to reach reward during the totem trials; together suggesting that presence of the moving totems did not influence the animals’ behaviour. There was no difference in latency to reach the reward zone based on absolute dominance rank when the animals foraged alone. N=54 total sessions across n=2 mice per rank. Error bars denote mean±95%CI.
