我们研究了狗是否依靠情景记忆来记住它们自发的过去行为。狗被训练根据要求重复一小部分动作。然后我们测试了他们重复自己做出的其他动作的能力，包括在日常情况下自发执行的动作。狗在延迟几秒到一小时后重复自己的动作，它们的表现表现出情景记忆的典型衰退。表现自己的行为并使用情景式记忆来回忆这些行为的综合证据表明，自我的一个关键特征的表现比以前归因于狗的要复杂得多。我们的方法适用于各种物种，为自我表征的进化和复杂性的比较研究铺平了道路。
We investigated whether dogs remember their spontaneous past actions relying on episodic-like memory. Dogs were trained to repeat a small set of actions upon request. Then we tested them on their ability to repeat other actions produced by themselves, including actions performed spontaneously in everyday situations. Dogs repeated their own actions after delays ranging from a few seconds to 1hour, with their performance showing a decay typical of episodic memory. The combined evidence of representing own actions and using episodic-like memory to recall them suggests a far more complex representation of a key feature of the self than previously attributed to dogs. Our method is applicable to various species, paving the way for comparative investigations on the evolution and complexity of self-representation.
