When displaying text on a page or a screen, only a finite number of characters can be presented on a single line. If the text exceeds that finite value, then text wrapping occurs. Often this process results in longer, more difficult to process words being positioned at the start of a line. We conducted an eye movement study to examine how this…

This quantitative study examines the Lexile level, estimated volume, and genre of fourth- and fifth-grade texts used in four popular core reading series to analyze the programs' possible effects on instruction and comprehension. The four series include Houghton Mifflin Harcourt's Into Reading, Lucy Calkins' Units of Study for Teaching Reading,…

When readers are asked to detect a target letter while reading for comprehension, they miss it more frequently when it is embedded in a frequent function word than in a less frequent content word. This missing-letter effect has been used to investigate the cognitive processes involved in reading. A similar effect, called the missing-phoneme effect…

This study explores the effectiveness of four-word frame training in enhancing the reading comprehension and contextual word-guessing skills of Thai public health students studying English as a Foreign Language. A mixed-methods approach was employed with 22 fourth-year undergraduate students, combining quantitative pre- and post-test assessments…

Arabic orthography is mainly presented either in shallow orthography (with all diacritics) for novice students or in deep orthography (without diacritics) for superior readers. However, the shallow orthography is heavily loaded with diacritics which may burden the reading process, whereas deep orthography can cause ambiguity (heterophonic…

Background: Reading researchers have generally considered that reading is an interactive combination of top-down (higher-level language skill) and bottom-up (lower-level language skill) processes. Nevertheless, the mechanisms through which readers apply these skills for online text comprehension are unclear. Methods: The present study thus used…

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…

Studies relating to the vocabulary items within EFL textbooks have revealed a divergence from well-researched wordlists such as the New General Service List (NGSL) (Browne et al., 2013), and the BNC/COCA wordlist (Nakayama, 2022; Sun and Dang, 2020). In Japan, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) recently…

Vocabulary knowledge is one of the most important elements of reading comprehension. Text coverage is the proportion of known words in a given text. We hypothesize that text comprehension increases exponentially with text coverage due to network effects and activation of prior knowledge. In addition, the lexical threshold hypothesis states that…

This dissertation investigates the ways that natural languages evolve and what it means in the overall cultural evolution of society. Computational and modeling advances have made possible to explore large-scale text data and test hypothesis of language evolution. Similar to biological systems, natural languages are evolving systems with words as…

General academic words are those which are typically learned through exposure to school texts and occur across disciplines. We examined academic vocabulary assessment data from a group of English-speaking middle school students (N = 1,747). We tested how word frequency, complexity, proximity, polysemy, and diversity related to students' knowledge…

Common tests of morphological awareness measure both morphology and syntax by requiring participants to fit words and pseudowords into sentences by adding or removing affixes. We report the results of a study testing a new word level task. College students viewed transparent words (without phonological or orthographic shifts) and used a keyboard…

In the current study, we examined relations between text features (e.g., word concreteness, referential cohesion) and reading comprehension using multilevel logistic models. The sample was 158 native English-speaking students between 8 years, 8 months and 11 years, 2 months of age with a wide range of reading ability. In line with the simple view…

This study examined structural priming during online second language (L2) comprehension. In two self-paced reading experiments, 64 intermediate to advanced Chinese learners of English as a foreign language read coordinated noun phrases where the conjuncts had either the same structure or different structures. Experiment 1 showed that the second…
