BP has been used extensively in human cognitive and memory modelling and
so it is useful to know if "cashes in" in terms of recognition memory as
well.

The interference issue is also problematic for training online control processes
(e.g. in robotic coordination) where new training data is not necessarily accompanied
by all of the "old" data samples. If there is not a nice regular general function to
be extracted, then forgetting could be very severe. Problems also arise for BP in any
such online task that requires discrimination between what was in the training sets and
what was not.
