Abstract
The goal of this study was to examine predictions derived from the Lexical Quality Hypothesis (Perfetti & Hart, 2002; Perfetti, 2007) regarding relations among word-decoding, working-memory capacity, and the ability to integrate new concepts into a developing discourse representation. Hierarchical Linear Modeling was used to quantify the effects of two text properties (length and number of new concepts) on reading times of focal and spillover sentences, with variance in those effects estimated as a function of individual difference factors (decoding, vocabulary, print exposure, and working-memory capacity). The analysis revealed complex, cross-level interactions that complement the Lexical Quality Hypothesis.
期刊介绍：
Discourse Processes is a multidisciplinary journal providing a forum for cross-fertilization of ideas from diverse disciplines sharing a common interest in discourse--prose comprehension and recall, dialogue analysis, text grammar construction, computer simulation of natural language, cross-cultural comparisons of communicative competence, or related topics. The problems posed by multisentence contexts and the methods required to investigate them, although not always unique to discourse, are sufficiently distinct so as to require an organized mode of scientific interaction made possible through the journal.
