I liked the postcard you sent Abe and I: Context-sensitive coding of syntax and other procedural knowledge

A theory of the coding of syntactic knowledge is described and illustrated by means of its predictions regarding certain pronomial case errors in children. The theory assumes two levels of syntactic coding: (1) word classes (noun, verb, adjective, adverb, articles, pronouns, prepositions, conjunctions) and (2) concept functions in a proposition (relation, agent, object, recipient, location, etc.). Both word-class nodes and concept-function nodes are context-sensitive (overlapping triple) codes, which is the key to their encoding of serial order in both recognition and production.
