>THE TRADITIONAL VIEW OF THE LEXICAL SYSTEM STIPULATES WORD-SPECIFIC
>REPRESENTATIONS AND SEPARATE PATHWAYS FOR REGULAR AND EXCEPTION WORDS. AN
>ALTERNATIVE APPROACH VIEWS LEXICAL KNOWLEDGE AS DEVELOPING FROM GENERAL
>LEARNING PRINCIPLES APPLIED TO MAPPINGS AMONG DISTRIBUTED REPRESENTATIONS OF
>WRITTEN AND SPOKEN WORDS AND THEIR MEANINGS. ON THIS DISTRIBUTED ACCOUNT,
>DISTINCTIONS AMONG WORDS AND BETWEEN WORDS AND NONWORDS ARE NOT REIFIED IN
>THE STRUCTURE OF THE SYSTEM BUT REFLECT THE SENSITIVITY OF LEARNING TO THE
>RELATIVE SYSTEMATICITY IN THE VARIOUS MAPPINGS. TWO SIMULATION EXPERIMENTS
>ADDRESS FINDINGS THAT HAVE SEEMED PROBLEMATIC FOR THE DISTRIBUTED APPROACH.
>BOTH INVOLVE A CONSIDERATION OF THE ROLE OF SEMANTICS IN NORMAL AND IMPAIRED
>LEXICAL PROCESSING. THE FIRST EXPERIMENT ACCOUNTS FOR PATIENTS WITH IMPAIRED
>COMPREHENSION BUT INTACT READING IN TERMS OF INDIVIDUAL DIFFERENCES IN THE
>DIVISION OF LABOR BETWEEN THE SEMANTIC AND PPHONOLOGICAL PATHWAYS. THE SECOND
>EXPERIMENT DEMONSTRATES THAT A DISTRIBUTED NETWORK CAN RELIABLY DISTINGUISH
>WORDS FROM NONWORDS BASED ON A MEASURE OF FAMILIARITY DEFINED OVER SEMANTICS.
>THE RESULTS UNDERSCORE THE IMPORTANCE OF RELATING FUNCTION TO STRUCTURE IN
>THE LEXICAL SYSTEM WITHIN THE CONTEXT OF AN EXPLICIT COMPUTATIONAL FRAMEWORK.
