A quick psychology tidbit, Science has a fun little paper showing that Theory of Mind (the ability to infer the mental states of others) is independent to Episodic Memory (memories of discrete episodes):
Theory of mind (ToM) to infer other people’s current mental states and episodic memory of personal happenings have been assumed to be closely related. We report two participants with severely impaired episodic memory who perform indistinguishably from healthy controls on objective ToM tests. These results suggest that ToM can function independently of episodic memory.
