Background: Recent research has documented individual differences in the reading profiles of skilled native English readers using a behavioural marker of holistic visual word processing (orientation sensitivity). A more holistic word reading profile is associated with a weaker correlation with phonological decoding for word identification.…

Background: Teaching vocabulary may be an effective way to address poor reading comprehension. However, it is unclear how many words or word families a school aged child with poor vocabulary would need to learn to meaningfully impact comprehension. This study provides estimates of vocabulary size for children with differing vocabulary achievement…

Background: In the present paper, we investigated the association between time spent reading and reading comprehension throughout the lifespan. According to the Matthew effect (or rich-get-richer and poor-get-poorer) model, interindividual differences in reading-related skills between poor and average readers become wider as individuals grow…

The present study examined children's digital text comprehension of digital text types linear digital text vs hypertext, with or without graphical navigable overviews. We investigated to what extent individual variation in children's comprehension could be explained by lexical quality (word reading efficiency and vocabulary knowledge), cognitive…

This study compared the effects of two brief prereading instructional practices--hands-on activities and prior knowledge activation--on sixth-graders' intrinsic motivation for reading a text and reading comprehension. Both hands-on activities and prior knowledge activation substantially improved reading comprehension relative to a control…

We report preliminary behaviour genetic analyses of reading and listening comprehension from The Colorado Learning Disabilities Research Center. Although the twin sample with these new measures is still of limited size, we find substantial, and significant, genetic influences on individual differences in both reading and listening comprehension.…
