Syllable and letter knowledge in early Korean Hangul reading.

This study examined the development of Korean consonant–vowel (CV) syllable identification, consonant and vowel letter knowledge, and their relationships to phonological awareness and the reading of regular Hangul words among Korean kindergartners as a 6-month longitudinal study. Results showed that Korean children identified CV syllables better than consonant and vowel letters. In regression analyses, CV syllable identification at Time 1 strongly contributed to Hangul word recognition concurrently over and above letter knowledge, as well as longitudinally after controlling for letter knowledge and reading at Time 1. However, letter knowledge did not predict Hangul reading once CV syllable identification was controlled. In addition, CV syllable knowledge facilitated subsequent letter knowledge and phoneme onset and coda awareness. The results, in general, shed light on the salient roles of syllables in the early literacy development of Korean. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The comprehensive language approach to early literacy: The interrelationships among vocabulary, phonological sensitivity, and print knowledge among preschool-aged children.

This article describes 2 points of view about the relationship between oral-language and literacy skills: The phonological sensitivity approach posits that vocabulary provides the basis for phonological sensitivity, which then is the key language ability supporting reading, and the comprehensive language approach (CLA) posits that varied language skills interact with literacy knowledge and continue to play a vital role in subsequent reading achievement. The study included 533 Head Start preschool-aged children (M=4 years 9 months) in 2 locations and examined receptive vocabulary, phonological awareness, and print knowledge. Partial correlational and regression analyses found results consistent with the CLA approach and evidence of a core deficit in phonological sensitivity, interpreted in a manner consistent with the CLA perspective.

Cognitive development and reading: The relation of reading-specific multiple classification skill to reading comprehension in elementary school children.

Cognitive flexibility, the ability to consider multiple aspects of stimuli simultaneously, develops over the elementary school years and can be measured with a multiple classification task. Although prior research indicates a significant relation between domain-general multiple classification skill (e.g., classifying objects by shape and color simultaneously) and reading, a precise relation between these abilities has not been found. A reading-specific multiple classification task was designed that required children to classify printed words along phonological and semantic dimensions simultaneously. Reading-specific multiple classification skill made a unique contribution to children's reading comprehension over the contributions made by children's age, domain-general multiple classification skill, decoding skill, and verbal ability. Additionally, training in reading-specific multiple classification facilitated children's reading comprehension. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Growth in literacy and cognition in bilingual children at risk or not at risk for reading disabilities.

This study investigated growth in reading, vocabulary, and memory in children (ages 5 to 10) learning English as a second language identified at risk for reading disabilities (RD). A growth curve analysis showed that RD children were significantly below children not at risk in English and Spanish reading, Spanish short-term memory (STM), Spanish comprehension, and English and Spanish working memory (WM). RD children were also inferior on growth measures of English and Spanish WM and Spanish STM. Growth on measures of Spanish vocabulary, reading, STM, and WM accounted for 12% of the variance in predicting growth in English reading. However, only Spanish measures of WM growth contributed unique variance. The results show that growth in WM in the primary language predicts growth in second-language reading.

Functional disruption of the brain mechanism for reading: Effects of comorbidity and task difficulty among children with developmental learning problems.

Objective: The study investigated the relative degree and timing of cortical activation associated with phonological decoding in poor readers. Method: Regional brain activity was assessed during performance of a pseudoword reading task and a less demanding, letter-sound naming task by three groups of students: children who experienced reading difficulties without attention problems (N = 50, RD) and nonreading impaired (NI) readers either with (N = 20) or without attention-deficit/hyperactivity disorder (ADHD; N = 50). Recordings were obtained with a whole-head neuromagnetometer, and activation profiles were computed through a minimum norm algorithm. Results: Children with RD showed decreased amplitude of neurophysiological activity in the superior temporal gyrus, bilaterally, and in the left supramarginal and angular gyri during late stages of decoding, compared to typical readers. These effects were restricted to the more demanding pseudoword reading task. No differences were found in degree of activity between NI and ADHD students. Regression analyses provided further support for the crucial role of left hemisphere temporoparietal cortices and the fusiform gyrus for basic reading skills. Conclusions: Results were in agreement with fMRI findings and replicate previous MEG findings with a larger sample, a higher density neuromagnetometer, an overt pseudoword reading task, and a distributed current source-modeling method.
