This study examined how lexical properties, such as word frequency, word length, and morphological features, affect the word recognition of Korean Hangul among adult readers. Ninety-four native Korean students performed a lexical decision task on disyllabic and trisyllabic words and nonwords. Results of cross-classified and hierarchical linear…

Emerging evidence suggests that executive function plays an important role in adult readers' understanding of text. This study examined the contribution of executive function to comprehension of expository science text among adult readers, as well as the role of vocabulary ability in the relation between executive function and text comprehension.…

The purpose of this study was to examine the shared, direct, and indirect contributions of three metalinguistic skills (phonological awareness, morphological awareness, orthographic knowledge) to the reading comprehension abilities of struggling adult readers. Across studies, these three metalinguistic skills have individually emerged as important…

We tested the effects of orthography on text reading by comparing reading measures in Arabic and Hebrew-speaking adults. The languages are typologically very similar, but use different orthographies. We measured naming speed of single letters, words and nonwords, and visual processing. Arabic-speakers also performed some of the tasks in Hebrew. We…

Research with school-age readers suggests that the contributions of reading and language skills vary across reading comprehension assessments and proficiency levels. With a sample of 168 struggling adult readers, we estimated the explanatory effects of decoding, oral vocabulary, listening comprehension, fluency, background knowledge, and…

The current study examined the relations among key variables that underlie reading comprehension of expository science texts in a diverse population of adult native English readers. Using Mechanical Turk to sample a range of adult readers, the study also examined the effect of text presentation on readers' comprehension and knowledge structure…

Adult literacy programs are characterized by high attrition rates. Rigorous exploration of student persistence in adult reading classes is lacking. This study was an attempt to understand the profiles of adults who completed reading classes compared to a group of adults who made it to the midpoint and a group of adults who did not make it to the…

This study extends the literature on the component skills involved in oral reading fluency. Dominance analysis was applied to assess the relative importance of seven reading-related component skills in the prediction of the oral reading fluency of 272 adult literacy learners. The best predictors of oral reading fluency when text difficulty was…

Using a large adult reading database, we examined the relationships between high-level and low-level reading skills and between multiple reading skills, general cognitive ability, and reading comprehension ability. A principal components analysis found partial dissociability between higher-level skills including reading comprehension, vocabulary…

Investigates effects of variations in font, leading, and justification that account for differences in speed and accuracy between reading aloud from paper versus laptop computer. Finds that: (1) subjects' prior exposure to print significantly and positively related to predicting speed and miscue performance; (2) educational attainment…
