At least in biological intelligences, attention is
focussed not so much on "what's interesting" as on
"what's salient", and what is salient can be very low
level indeed (e.g. a loud bang behind you). It is
maladaptive to only react once cognitive processes
have decided the bang might be important, so animals
have short-cuts (e.g. the superior colliculus).
