It seems to me that the point is not the short/long
memory, and related consciousness, but the 'observing
directly'. If the observer measures and knows the 'which 
way' every particle took, the pattern on the screen 
is smooth. If the observer measures and knows nothing, 
the pattern is fully interferential. If the observer 
measures partially and knows partially the 'which way' 
every particle took, he gets a partial interference 
pattern.

The interference pattern depends on the quantity of
information the observer chooses to get (through
the measurement apparata). 

Imagine a chameleon. On a green carpet his colour
is green. On a brown carpet his colour is brown.
On a green-brown carpet his colour should be
green-brown, I suppose :-). What is the true
colour of a chameleon? And what is the true shape
of a photon? Limited and finite is the available
information.
