    There are currently four  models  of  symbolic  computation  which  are  in
frequent   use  in  Cognitive  Science  work:  applicative  programming,  logic
programming,  rule-based  programming,  and  object  oriented   (frame   based)
programming.     Each  of  these  exhibit  some  general  properties  of  human
information processing, but neglects others.   For  example,  LISP  contains  a
model for the hiearchical structure of action, which Production Systems do not.
What is needed for the simulation of human  cognition  is  a  new  architecture
which  exhibits all of the properties which we know are characteristic of human
cognition, and which "has" them in a natural way.  An attempt at defining  such
an  architecture  will be presented.  It has grown within a specific simulation
attempt,  namely   to   understand   formally   what   happens   in   so-called
"Aha"-experiences,  moments  of  insight  during problem solving.  A theory has
been constructed which explains such events within the  information  processing
theory  of problem solving as heuristic search.  The theory is then implemented
within the architecture described.  An example of a run of the system  will  be
described.
