Summary: Analyzes a psychological protocol of a person planning a
group of errands to run.  Uses this protocol to demonstrate the
feasibility of a model of cognition which involves a set of "cognitive
specialists" working at various levels of abstraction and
communicating via a "blackboard."  Describes the different portions of
the blackboard and how they correspond to observed behavior in the
protocol.  Describes a computer simulation intended to follow the same
reasoning paths as the subject.  Contrasts their work with traditional
(i.e. successive refinement) planning strategies.
