MODELS OF READING ALOUD - DUAL-ROUTE AND PARALLEL-DISTRIBUTED-PROCESSING APPROACHES

It has often been argued that various facts about skilled reading alou d cannot be explained by any model unless that model possesses a dual- route architecture (lexical and nonlexical routes from print to speech ). This broad claim has been challenged by Seidenberg and McClelland ( 1989, 1990). Their model has but a single route from print to speech, yet, they contend, it can account for major facts about reading that h ave hitherto been claimed to require a dual-route architecture. The au thors identify 6 of these major facts about reading. The 1-route model proposed by Seidenberg and McClelland can account for the first of th ese but not the remaining 5. Because models with dual-route architectu res can explain all 6 of these basic facts about reading, the authors suggest that this remains the viable architecture for any tenable mode l of skilled reading and learning to read. The dual-route cascaded mod el, a computational version of the dual-route model, is described.
