"Moody raised his wand, pointed it at Harry and 
said, "Imperio!"
..Jump onto the desk
.Why, though?  Another voice 
had awoken in the back of his brain
.no I don't really want to
 
(pages 231 & 232 American edition, GOF)

And then we have: "I have been told that you have already shown 
aptitude at resisting the Imperius Curse.. You will find that 
similar powers are needed for this
 Legilimens!...

.No, said a voice in Harry's head, as the memory of Cho grew 
nearer, you're not watching that
.. Snape's office had come back 
into view and he realized that he'd fallen to the floor; 
"did you mean to produce a Stinging Hex?"
 (page 534 OOP).
We are meant to believe that Harry isn't any good at occlumency, but 
I think a comparison of the two passages indicates that actually 
Harry
is innately GOOD at keeping unwanted intrusions out of his mind.  He 
has the same initial problem with Imperio, then throws it off as he 
does with Legilimens.  The difference is that whereas fake!Moody 
actually lets him succeed, Snape disparages Harry's response even 
although it works well enough to force Snape OUT of Harry's head and 
add a stinging hex to boot.  Thereafter, Snape uses Harry's emotions 
to unsettle him and insists that Harry "rid your mind of all 
emotion..."(page 538 OOP).  Moody doesn't insist that Harry fight 
off the Imperius in a particular fashion -- he merely encourages 
Harry in doing it.
I find the comparison interesting.
