[ACT-R-users] Cognition and perception

[Mohan Arun L]

Cognition and perception
------------------------------------
"Cognition rests on, and adds to, perception.
...
Perception seems more closely tied to sensation, and so
is largely event-driven, whilst cognition is more
associated with the nuts and bolts of 'thinking about' things, and so is
more symbol-driven, a little more 'top-down'. So it has sometimes been
possible to to talk about 'direct perception' (sometimes, but not always, in
the same context as 'sense-perceptions'), but I don't remember coming across
'direct cognition'."
