The dual-route model of reading is a cognitive framework that explains how individuals process written language through two distinct pathways: the lexical route and the non-lexical route. The lexical route involves recognizing whole words and accessing their meanings from memory, while the non-lexical route focuses on phonological decoding, where readers convert letters into sounds to read unfamiliar words. This model highlights the complexity of reading as it illustrates that readers can employ different strategies depending on their familiarity with the words and the context.
