Hi In most of the examples given, I think people are being too harsh to say that the results are ridiculous or meaningless. When one "estimates" some hypothetical value there may be conditions where the underlying value is so close to a maximum or a minimum that your estimate falls above the m

Hi Joan- While anything may be possible I don't think that this case is very plausible. This is not simply a case of losing semantic memory while retaining procedural memory (I think that there is evidence for that). Rather, this is a case where we are to believe that episodic memories can be
