The Modeling of Simple Analogic and Inductive Processes in a Semantic Memory System

I . I n t roduc t i on The model descr ibed in t h i s paper represents on attempt to fo rmal ize a number of general cogn i t i v e processes. Although these processes may be sa id to be "s imp le" in the sense of being p r i m i t i v e s of cogn i t i ve behavior , they are by no means simple t o make e x p l i c i t i n t h e i r f u l l gene ra l i t y . Wi th in the conf ines of t h i s paper we could not begin to discuss a l l o f the i n t r i c a c i e s o f modeling these processes, and i f we cou ld , the reader could not begin to so r t out the main ideas under ly ing the model. Therefore we have chosen to present the elements of the model in an ove rs imp l i f i ed form designed to b r i n g out the major ideas they embody; then i n separate sect ions (Sections I I . C , I I I . B , and V.B) we i nd i ca te what e laborat ions must be made in order f o r the model to be t r u l y genera l . In Sect ion V.B we a lso discuss the formidable problems t ha t a r i s e in v a l i d a t i n g a model such as t h i s one.
