What does Perfetti's Lexical Quality Hypothesis (LQH) emphasize?

Perfetti's Lexical Quality Hypothesis (LQH) emphasizes the importance of multiple interactions with words across various contexts to strengthen understanding and recognition. According to this hypothesis, the quality of a person's word knowledge is not solely based on a single experience or the ability to pronounce or spell a word. Instead, it highlights that a rich, diverse exposure to words helps in developing deeper meanings and connections, which are crucial for effective reading and writing.

This multifaceted engagement with words allows learners to build a more robust mental representation of vocabulary, ultimately facilitating better comprehension and fluency. It underlines the significance of context and repeated use in solidifying literacy skills, indicating that frequent, varied encounters with words enhance one's lexical quality and contribute to overall literacy development.
