The second major body of research in cognitive psychology
has sought to explain the mental processes that operate on the
representations we construct of our knowledge of the world.
Of course, it is not possible to separate our understanding, nor
our discussion, of representations and processes. Indeed, the
sections on mental models and expertise made this abundantly
clear.However, a body of research exists that has tended to focus
more on process than representation. It is to this that we now
turn.
