Drawing on Geary's (1995) evolution-based model of cognitive and academic development, this study investigated the relation between biologically primary skills (vocabulary, executive functions, and visual-spatial processing) and subsequent word reading and calculation. It also examined the extent to which these relations were mediated by…

This study examined the relationships of 3 levels of reading fluency--the individual word, the syntactic unit, and the whole passage--to reading comprehension among 278 5th graders heterogeneous in reading ability. Hierarchical regression analyses revealed that reading fluency at each level related uniquely to performance on a standardized reading…

The relationship between lower level code availability and top-down contextual processing in word recognition was investigated in two experiments. The major finding was that the increment in performance resulting from coherent organization relative to the random passage was equivalent in both normal and reversed orthographic forms. (Author/GK)

Three experiments exploring the relationship of cognitive effort to the differences in word recall between skilled and learning disabled readers are described. Results suggest the amount of cognitive effort that can be effectively expended to produce a distinctive memory trace is related to individual differences in attentional capacity.…

Correlations between phonological, orthographic, semantic, metacognitive, and working memory measures were studied for 40 learning-disabled students and 40 skilled readers ages 8 to 12. Results suggest that the cognitive processes that contribute to reading deficits are best understood in the context of their combination with other operations.…

A study of 51 third and 47 fourth graders using a new measure of exposure to print, the Title Recognition Test, established that orthographic processing ability can account for variance in word recognition skill after variance resulting from phonological processing is removed. The importance of print exposure is discussed. (SLD)

Performance on a battery of tests of vocabulary words by 72 college students was compared as a function of whether the prior instruction involved presenting material in an organized or scrambled fashion. Organizing vocabulary words during study facilitated performance in categorizing, processing for understanding, or producing a word. (SLD)

The authors determined whether the cognitive processes that underlie second-language acquisition difficulties are the same as those that underlie reading difficulties. First-grade (N = 101) bilingual and nonbilingual children were administered a battery of measures in Spanish and English. English word identification and vocabulary were predicted…

Mirror-image animal and nonanimal words of three to six letters were presented to subjects in a reaction time categorization task. A significant interaction of Word Length X Block was found for words presented over all four blocks. A shift from component to holistic processing was found for the repeated words. (Author/RD)

A new regression-based logic strategy is presented for comparing cognitive profiles of children developing reading skills at different rates. Results with 907 children support the phonological-core variable-difference model of reading disability, with the degree of aptitude-achievement discrepancy unrelated to unique cognitive trade-offs of…
