00100		This monograph  describes  a  computer  simulation  model  of
00200	paranoia.  The  significance  of  this  work lies in the systemicity,
00300	testability and appropriateness of the model.
00400		(1) Systemicity: it provides a systematic explanation of 
00500		    phenomena characteristic of paranoid symbolic (linguistic)
00600		    behavior in a pstchiatric interview.
00700		(2) Testability: it describes a number of appropriate tests
00800		     for measuring the success of the simulation which
00900		     were applied to the model.
01000		(3) Appropriateness: the symbolic level of analysis utilized
01100		    is useful for the understanding, prediction and influence
01200		    of pathological symbolic behavior such as is found in
01300		    the paranoid mode.
01400	Each of these points will be elaborated on.
01500			
01600	Systemicity
01700		Previous formulations of paranoid behavior have been  neither
01800	systematic  or  testable.  Cast in literary form, they were vague and
01900	ambiguous. If they consisted of  single  hypotheses,  they  were  too
02000	global to be useful. If they consisted of conjunctions of hypotheses,
02100	they could not be tested for consistency.
02200		The  new  theory provided in the monograph is modelled in the
02300	form  of  an  interactive  simulation  of  paranoia.  More  precisely
02400	sequences  of  paranoid  symbolic  behavior  typical of a psychiatric
02500	interview are explained in terms of the operations of  an  underlying
02600	structure  of  symbol-manipulating processes. The logic of this level
02700	of analysis and explanation is explored  in  detail  along  with  the
02800	roles of analogies, alogorithms and functional equivalence. Since the
02900	model consists of an algorithm running on a computer, the consistency
03000	requirement of scientific theories is met.
03100	
03200	Testability
03300		The model can be interviewed using unrestricted English. Thus
03400	the interviewer  can  experience  for  himself  the  impaired  social
03500	relationship characteristic of the paranoid stance.
03600		This simulation represents the first model of psychopathology
03700	which  has  been  tested  by comparing dialogue behavior of the model
03800	with  dialogue  behavior  with  its  naturally-occuring  counterpart.
03900	Several  validation  procedures  are  described  and evaluated. It is
04000	concluded that a multidimensional evaluation is the best  measure  of
04100	the  success of a simulation. This approach also provides a means for
04200	improving the model along relevant dimensions.
04300	
04400	Appropriateness
04500		Psychiatrists  deal  with their patients mainly at a symbolic
04600	level using natural language communication. Therefore it  is  at  the
04700	symbolic  level  of analysis that explanations are the most useful in
04800	providing  understanding.  The  model  offers  the  right   type   of
04900	explanation  since  its  level  of detail matches the level of detail
05000	familiar to and used by clinicians. Thus  the  model  has  a  further
05100	potential  as  a training device for medical students and psychiatric
05200	residents.
