I think you are confusing memory and perception. For economy,
people's long-term memory of an event may rely on using mental
paradigms (thus confusing minor details like red and orange
basketballs), but the immediate perception is not somehow
overridden by the paradigm. Ask the same group to focus their
attention specificially on the color of the basketball while
watching the movie and I'm quite sure they all would have
responded "red".

Sorry Jason, but that's just bunk. If you really think "seeing
does not involve the visual cortex," then how do you explain
people going completely blind when their visual cortex is
destroyed by stroke, gunshot wound, etc.? The visual cortex is
the most studied area of the brain with a vast literature
devoted to it. It would certainly come as a great surprise to
the experts that the visual cortex plays no role in seeing, as
you claim.

I don't think so. Do you really think your brain can't
distinguish between a cactus and your Mother without guide from
the emotional centers? Yes, events that trigger your emotional
centers in a big way (car accident, bank robbery, etc.) may
affect how one attends to and therefore remembers event but this
generally has minimal or no effect on how one immediately
perceives events that are attended to. And this is very much the
domain of the extremely well-studied visual cortex.

Emotion affects perception primarily through how the brain
directs its attention. Usually we are more interested in the
overall scenario rather than the irrelevant details. That's
where most of the survival value is.

Thus if one sees a big animal running directly at you, it is
more important to pay attention to the fact that it is big, it
is approaching you fast, how far away it is, where one might
escape to, and so on. One is very much aware that this is a
dangerous situation and is directing attention to what might
help you survive. Whether some psychologist painted the tiger
red to try to trip you up afterwards so they can write learned
papers on how poor eyewitnesses are is not high on your list of
priorities.

However if you are searching for food and the yellow fruit is
good to eat while the otherwise identical green fruit is not,
then one important thing to attend to is the color. You will not
misperceive the green banana as yellow because your mental
paradigm of banana is yellow.

But at a basketball game, nobody gives a damn what color the
basketball is because it's not important (certainly not in a 13
second movie clip). Therefore they are likely to fail the
simplistic psychology test afterwards, but not because their
visual cortex can't distinguish color when attention is turned
to that task.

If people were really as bad at perceptual tasks as you are
trying to depict them here, natural selection would have gotten
rid of the human race a long time ago and we wouldn't be having
this conversation.
