Reading comprehension tests vary in format and characteristics, which may influence the extent to which component skills are involved in test performance. With students in Grades 6 to 8 with reading difficulties, dominance analyses examined the differential importance of component reading and language skills (word- and text-reading fluency,…

Reading comprehension is based on the efficient accomplishment of several cognitive processes at the word, sentence, and text level. To the extent that each of these processes contributes to reading comprehension, it can cause reading difficulties if it is deficient. To identify individual sources of reading difficulties, tools are required that…

The current study examined statistically significant differences between struggling and adequate readers using a multicomponent model of reading comprehension in 796 sixth through eighth graders, with a primary focus on word reading and vocabulary. Path analyses and Wald tests were used to investigate the direct and indirect relations of word…

Modern behavior-genetic studies of twins in the United States, Australia, Scandinavia, and the United Kingdom show that genes account for most of the variance in children's reading ability by the end of the 1st year of formal reading instruction. Strong genetic influence continues across the grades, though the relevant genes vary for reading words…

There are no salient word spaces in Mandarin Chinese. Thus, it is unclear whether word spacing information differentially affects the reading speed of children with and without reading difficulties (RD). In the present study, native Chinese-speaking children of differential reading abilities were tested with Chinese text in un-spaced versus spaced…

Many children learning English as an additional language (EAL) show reading comprehension difficulties despite adequate decoding. However, the relationship between early language and reading comprehension in this group is not fully understood. The language and literacy skills of 80 children learning English from diverse language backgrounds and 80…

Does the choice of test for assessing reading comprehension influence the outcome of genetic analyses? A twin design compared two types of reading comprehension tests classified as primarily associated with word decoding (RC-D) or listening comprehension (RC-LC). For both types of tests, the overall genetic influence is high and nearly identical.…

Language and oculomotor disturbances are 2 of the best replicated findings in schizophrenia. However, few studies have examined skilled reading in schizophrenia (e.g., Arnott, Sali, Copland, 2011; Hayes & O'Grady, 2003; Revheim et al., 2006; E. O. Roberts et al., 2012), and none have examined the contribution of cognitive and motor processes that…

This study investigated predictors of word reading and reading comprehension skills using longitudinal data from Spanish-speaking kindergartners (N = 163) and first grade students (N = 305) from high SES families in Chile. Individual differences in letter-naming fluency and phonemic segmentation fluency, but not vocabulary, were positive…

Improving reading rate can be difficult for poor readers. In this experiment, we investigated the impact of improvement in reading rate on other aspects of reading, including word recognition, decoding, vocabulary, and comprehension. Poor readers in Grades 2 or 4 (N = 123) were randomly assigned to 1 of 3 conditions: practice reading text at their…

There is a growing literature demonstrating that speech rhythm sensitivity is related to children's reading development, independent of phonological awareness. However, the precise nature of this relationship is less well understood, and further research is warranted to investigate whether speech rhythm sensitivity predicts the different…

The literature on individual differences in cognitive processes that operate at the text level is reviewed. Poor readers display comprehension deficits independent of word-decoding skill, due to deficient syntactic abilities and to more general metacognitive strategies. The general conclusions from this review and from Part One (ED 150 706) are…

We used Barton and Sanford's (1993) anomaly detection task to investigate text processing differences between skilled and less-skilled readers. The results of 2 experiments showed that many readers had the tendency to process text in a shallow or incomplete manner, frequently failing to detect anomalous nouns or noun phrases (NPs) in text such as…

The article summarizes findings of research on individual differences in reading ability, noting the primary effects of lack of phonological awareness on the ability to phonologically segment, analyze, and synthesize the speech stream. Other sources of individual differences are also addressed: early visual processes, naming processes, context,…

Explores the effects of question task conditions on reading comprehension and metacomprehension for proficient readers, disabled readers, and deaf readers. Finds several significant interaction effects for both demonstrated and perceived comprehension performance in selected-response and constructed-response question tasks under both lookback and…
