Word Decoding Development during Phonics Instruction in Children at Risk for Dyslexia.

In the present study, we examined the early word decoding development of 73 children at genetic risk of dyslexia and 73 matched controls. We conducted monthly curriculum‐embedded word decoding measures during the first 5 months of phonics‐based reading instruction followed by standardized word decoding measures halfway and by the end of first grade. In kindergarten, vocabulary, phonological awareness, lexical retrieval, and verbal and visual short‐term memory were assessed. The results showed that the children at risk were less skilled in phonemic awareness in kindergarten. During the first 5 months of reading instruction, children at risk were less efficient in word decoding and the discrepancy increased over the months. In subsequent months, the discrepancy prevailed for simple words but increased for more complex words. Phonemic awareness and lexical retrieval predicted the reading development in children at risk and controls to the same extent. It is concluded that children at risk are behind their typical peers in word decoding development starting from the very beginning. Furthermore, it is concluded that the disadvantage increased during phonics instruction and that the same predictors underlie the development of word decoding in the two groups of children. © 2017 The Authors Dyslexia Published by John Wiley & Sons Ltd.

Lexical orthographic knowledge develops from the beginning of literacy acquisition

This study reports two experiments assessing the spelling performance of French first graders after 3 months and after 9 months of literacy instruction. The participants were asked to spell high and low frequency irregular words (Experiment 1) and pseudowords, some of which had lexical neighbours (Experiment 2). The lexical database which children had been exposed to was strictly controlled. Both a frequency effect in word spelling accuracy and an analogy effect in pseudoword spelling were obtained after only 3 months of reading instruction. The results suggest that children establish specific orthographic knowledge from the very beginning of literacy acquisition.

Predicting Delay in Reading Achievement in a Highly Transparent Language

A random sample of 91 preschool children was assessed prior to receiving formal reading instruction. Verbal and nonverbal measures were used as predictors for the time of instruction required to accurately decode pseudowords in the highly orthographically regular Finnish language. After 2 years, participants were divided into four groups depending on the duration of instruction they had required to reach 90 % accuracy in their reading of pseudowords. Participants were classified as precocious decoders (PD), who could read at school entry; early decoders (ED), who learned to read within the first 4 months of Grade 1; ordinary decoders (OD), who learned to read within 9 months; and late decoders (LD), who failed to reach the criterion after 18 months of reading instruction at Grade 2. Phonological awareness played a significant role only in differentiating PD from ED and OD. However, phonological awareness failed to predict the delayed learning process of LD. LD differed from all other groups in visual analogical reasoning in an analysis not containing phonological awareness measures. Letter knowledge and visual analogical reasoning explained above 90% of the PD-LD difference. Preschool composite (objects, colors, and digits) naming speed measures best predicted reading fluency at the end of Grade 2. The supportive role of orthographic knowledge in phonological awareness, the role of visual analogical reasoning, and the inability of phonological measures to discriminate late decoders are discussed.

The early manifestation of developmental dyslexia: Evidence from German children

The present study retrospectively examined early difficulties with phonological coding and phonemic segmentation of German children who after four years in school were diagnosed as dyslexic. German, in comparison to English, exhibits rather simple and straight-forward grapheme-phoneme correspondences, and the initial teaching approach was phonics oriented. Despite these favorable circumstances for the acquisition of phonological coding, the majority of the later dyslexic children had particular difficulties with the accurate reading of nonwords and of unfamiliar words after about seven months of reading instruction. However, there were enormous differences between the dyslexic children. Two of them were completely unable to ‘blend’ phonemes into pronunciations, another seven were slow and error prone decoders, and three children had slow and laborious pronunciation assembly as the core problem. The majority of the later dyslexic children also exhibited phonemic segmentation deficits as tested with a nonword spelling task and a phoneme reversal task. In correspondence with findings from older German dyslexic children, the early difficulties with accurate phonological coding and phonemic segmentation were no longer found at the end of grade four. Children then suffered from very slow reading and poor spelling. In general, the difficulties of German dyslexic children emphasize the phonological impairment account of dyslexia. More specifically, these findings suggest that the assembly of letter sounds into pronunciations is particularly affected in the early phase of learning to read a consistent orthography.

An investigation into the relation between word recognition skills, reading comprehension and spelling skills in the first two years of primary school

ABSTRACTDuring the past five years a comprehensive research project called ‘The prevention of reading difficulties’ has been designed and carried out in the Netherlands. This project included a longitudinal study to investigate the development of various sub‐skills in word recognition, reading comprehension and spelling over a period of three years.Two samples, including 12 schools each, were drawn at random. The data have been analysed by means of the general LISREL‐model. The results of the two groups largely agree with each other. With respect to the reading prerequisites two factors are found, a general factor and an auditory factor. The influence of the general factor appears clearly stronger than the other one.After 3 to 4 months of formal reading instruction, decoding speed and spelling turn out to be distinguishable factors. The influence of spelling on decoding skills supports the view that at this initial stage accuracy in the analysis and blending of words is a prerequisite to learning to decode quickly. It may be concluded that after eight months of reading instruction decoding skills, reading comprehension and spelling are clearly distinguishable factors. Decoding skills influence reading comprehension. However, the path coefficients are not so high as to be able to attribute differences in reading comprehension almost completely to differences in decoding skills.The distinctive character of the three factors of decoding, comprehension and spelling is revealed much more clearly than in cross‐sectional research. These results correspond with the assumption that cross‐sectionally found causal effects often decrease or disappear all together in favour of ‘memory effects’ in longitudinal research.
