Studies of the ability of animals to take into account the limits of their bodies when penetrating into various holes and openings are a well-developed direction of research in body awareness. Here we studied the ability of brown rats (Rattus norvegicus) to take into account their body weight. To solve the experimental problem, the animals had to correlate their body weight with the strength of the support along which they moved. It was found that 8 out of 25 rats were able to solve this problem. During the experiment, the rodents demonstrated characteristic “testing movements”, during which, we believe, they correlated their own weight with the characteristics of external objects. We consider these results to be a demonstration of the awareness of their weight in rats as one of the body-awareness modules. |
