In this study, I investigated the simultaneous effects of the reader, the text, and the task factors, and their interactions, on reading comprehension, using explanatory item response models. Analyses of a large data set from a commercially available online assessment system with a wide range of readers (n = 10,547) and passages (n = 48) uncovered…

This article presents 34 characteristics of texts and tasks ("text features") that can make continuous (prose), noncontinuous (document), and quantitative texts easier or more difficult for adolescents and adults to comprehend and use. The text features were identified by examining the assessment tasks and associated texts in the national…

Adults are able to access semantic and syntactic information rapidly as they hear or read in real-time in order to interpret sentences. Young children, on the other hand, tend to rely on syntactically-based parsing routines, adopting the first noun as the agent of a sentence regardless of plausibility, at least during oral comprehension. Little is…

In 3 experiments, the author examined how readers' eye movements are influenced by joint manipulations of a word's frequency and the syntactic fit of the word in its context. In the critical conditions of the first 2 experiments, a high- or low-frequency verb was used to disambiguate a garden-path sentence, while in the last experiment, a high- or…

A reduced relative-main clause ambiguity occurs in sentences that begin with reduced relative clauses, as in "The hangman executed by the government was convicted of treason." This ambiguity has often been the focus of research designed to investigate the processes by which syntactic structures are built during sentence comprehension.…
