Richard:the idea that "perception is [the] fairly passive reception

processing
No it isn't. You're jumping the gun again. The debate has moved
further on since last you seem to have looked :):
Huh? [Baffled look]. In your earlier message you raised the issue of
whether PERCEPTION was a passive or active thing:
We're recognising that perception is not as was once thought fairly
passive reception of impressions, later checked and corrected by the
rational brain, but active exploration and intelligent from the v.
beginning.
I addressed this specific claim, which is false because cognitive
science recognized the existence of expecation-driven perception decades
ago.
The enactive perception debate that you cite below is mostly about
something different (though related): the question of whether there is
a clean separation between perception and ACTION (not whether perception
is influenced by expectation, but whether the things you sense are
partly determined by the things you are doing). See, for example, the
first line of the Prinz paper you cite below, where he says:
"Alva Noë’s Action in Perception offers a provocative and vigorous
defense of the thesis that vision is enactive: visual experience depends
on dispositional motor responses. On this view, vision and action are
inextricably bound."
This is a new debate that does not negate the conclusions of the older
debate at all.
So, yes, of course people are debating newer issues (they have got to
push back the frontiers), but that has nothing to do with our comment,
which seemed to refer to the much older, completely resolved question.
Now, if what you *meant* to talk about was links between action and
perception, all well and good, but I was just addressing the above
comment of yours.
