Humans possess the ability to recall past events. They can also imagine the course of future events. This phenomenon is known as mental time travel. The basis of travelling into subjective past lies in episodic memory. When we travel into subjective future we deal with planning, anticipation, as well as prospective memory. The basic scientific question that can be raised is as follows: are subjective time travels unique to Homo sapiens? Is the Bischof-Kohler hypothesis true? In this paper the author presents arguments and empirical data, which shed a different light on this issue.
