| Research Abstract |
In this study, we examined the possible ability of a rodent, degu (Octodon degu)to hierarchically combine multiple objects to construct a self-embedded structure. Before experiment, experimental apparatus, nesting-cup, were improved to make up for degu's physical disadvantage. We trained degus to manipulate cups by step-by step training procedure. In analyzing these data, we adopted the notation system for describing manipulation in nesting-cup tasks in the form of sequential codes as Hayashi (2007).As a result of this analysis, the change of strategy by degus in manipulating nesting-cup was proved to be similar with that by chimpanzee. Finally, degu operated four cups by the pot method, but they have never used the subassembly method. Our results experimentally demonstrated that the most developed method of degus was the pot method.
