1. mental model
against which a visual comparison is made. Search images
are formed as animals
search for food
or mates and optimize behavior
by allowing an animal
to systematically choose certain resources
or individuals and to ignore others.
2. in reference to an animal
focusing on a particular item; for example, a primate
looking for food
may only give its attention to a particular type
at one time as long as it is rewarding to do so; this term
is used almost exclusively for selective foraging.
