This study longitudinally investigated the relationships between verbaland visual short-term memory (STM) and the acquisition of decoding from thepre-reading through the early acquisition stages in 63 Hebrew-speakingchildren Test waves occurred in kindergarten, first grade and second grade.IQ, visual and verbal STM and decoding ability were assessed. The dataindicated that while both verbal and visual STM in kindergarten were significantlycorrelated to later decoding skill, pre-reading visual STM was a stronger predictor.The results further showed that pre-reading performance on the WISC-R BlockDesign test predicted later decoding ability, while performance on theWISC-R Vocabulary test did not. Lastly decoding skill in grade 1 was foundto predict only visual in grade 2. These results indicate that visualparameters may make a crucial contribution to the acquisition of decodingskills. The size of pre-reading visual STM capacity appears to play a rolein this process. The relationship between visual STM and decoding may bebidirectional, as learning to decode appears to develop visual STM. It issuggested that either language-related or task-related factors may accountfor these counter-to-mainstream results. 相似文献

The Reading Acceleration Program (RAP), which uses adaptively increasing text erasure rates to enforce reading rate improvements, has been positively evaluated in various languages, reader and age groups. The current study compared the established incremental increase of text erasure rate with a training using fixed erasure rates in two groups of young, non-impaired German adults. Eye-tracking measures prior and post training examined training-related changes of eye-movement patterns. Equal gains in reading performance in both training groups led to the conclusion that not the adaptive increase but already text erasure at fixed rates provides an economically efficient tool for the enhancement of reading rates. Furthermore, eye-tracking results suggest that text erasure training affects word processing not only at one specific level, but simultaneously at pre-lexical, lexical, and post-lexical stages. Although these outcomes are promising, further research is necessary to determine the optimal individual erasure rates that preserve good comprehension at varying levels of text difficulty and in different orthographies. 相似文献

Brain activity of regular and dyslexic readers while reading Hebrew as compared to English sentences
The aim of the present study was to examine differences among regular and dyslexic adult bilingual readers when processing reading and reading related skills in their first (L1 Hebrew) and second (L2 English) languages. Brain activity during reading Hebrew and English unexpected sentence endings was also studied. Behavioral and electrophysiological measures including event-related potentials (ERP) and low resolution electromagnetic tomography (LORETA) methodology were employed. Results indicated discrepancies in the processing profiles of dyslexic and regular bilingual readers in both first and second languages. In general, the amplitudes of the evoked potentials were higher and the latencies longer among dyslexic readers during processing of information in first and second languages (L1 and L2), but were more pronounced in English (L2). LORETA analysis indicated evidence that the source of brain activity measured by current density of brain activation is different when reading Hebrew as compared to English sentences mainly among dyslexics and not among regular readers. The data from the present study supports the dominanat bilingual hypothesis for defining bilinguals. A discrepancy between achievement in performing various L1 and L2 tasks was consistent across groups. Both groups were better in there mother tongue, which was Hebrew as compared to English. 相似文献
