Phonological skills and their role in learning to read: A meta-analytic review.

The authors report a systematic meta-analytic review of the relationships among 3 of the most widely studied measures of childrens phonological skills (phonemic awareness, rime awareness, and verbal short-term memory) and childrens word reading skills. The review included both extreme group studies and correlational studies with unselected samples (235 studies were included, and 995 effect sizes were calculated). Results from extreme group comparisons indicated that children with dyslexia show a large deficit on phonemic awareness in relation to typically developing children of the same age (pooled effect size estimate: -1.37) and children matched on reading level (pooled effect size estimate: -0.57). There were significantly smaller group deficits on both rime awareness and verbal short-term memory (pooled effect size estimates: rime skills in relation to age-matched controls, -0.93, and reading-level controls, -0.37; verbal short-term memory skills in relation to age-matched controls, -0.71, and reading-level controls, -0.09). Analyses of studies of unselected samples showed that phonemic awareness was the strongest correlate of individual differences in word reading ability and that this effect remained reliable after controlling for variations in both verbal short-term memory and rime awareness. These findings support the pivotal role of phonemic awareness as a predictor of individual differences in reading development. We discuss whether such a relationship is a causal one and the implications of research in this area for current approaches to the teaching of reading and interventions for children with reading difficulties.

The effects of morphological versus phonological awareness training in kindergarten on reading development

The aim of this study was toinvestigate the long-term effects of twodifferent training programs in kindergarten onreading development. One group received aprogram focusing on the phonological structureof words, while a second group received aprogram focusing on morphology. Both groupsalso had some print exposure focusing onphonological or morphological elementsrespectively. During their last pre-schoolyear, participants received training for 30minutes per week for a total of 17 weeks. Acontrol group received no intervention but wasregularly visited by the researcher and hadextensive print exposure. Both trained groupsshowed improvements in phonological,morphological and reading skills in comparisonto the Control Group. The effects of trainingvaried according to mothers educational level:Children of relatively highly educated mothersentered the pre-school training with betterdeveloped metalinguistic abilities thanchildren of less well educated mothers.Significant interactions between the groups andthe mothers educational level, for some of theschool reading measures, indicated thatdifferent training programs had differenteffects on different groups of children.Children of poorly educated mothers profitedthe most from metaphonological training whilechildren of highly educated mothers profitedthe most from metamorphological training.

Language and verbal short-term memory skills in Children with Down syndrome :A meta-analytic review

This study presents a meta-analytic review of language and verbal short-term memory skills in children with Down syndrome. The study examines the profile of strengths and weaknesses in children with Down syndrome compared to typically developing children matched for nonverbal mental age. The findings show that children with Down syndrome have broad language deficits (that are not restricted to measures of expressive language) and associated verbal short-term memory deficits. The profile of language skills in children with Down syndrome shows similarities to that seen in children with Specific Language Impairment. The practical and theoretical implications of these findings are discussed.

Sentence repetition is a measure of children's language skills rather than working memory limitations

Sentence repetition tasks are widely used in the diagnosis and assessment of children with language difficulties. This paper seeks to clarify the nature of sentence repetition tasks and their relationship to other language skills. We present the results from a 2-year longitudinal study of 216 children. Children were assessed on measures of sentence repetition, vocabulary knowledge and grammatical skills three times at approximately yearly intervals starting at age 4. Sentence repetition was not a unique longitudinal predictor of the growth of language skills. A unidimensional language latent factor (defined by sentence repetition, vocabulary knowledge and grammatical skills) provided an excellent fit to the data, and language abilities showed a high degree of longitudinal stability. Sentence repetition is best seen as a reflection of an underlying language ability factor rather than as a measure of a separate construct with a specific role in language processing. Sentence repetition appears to be a valuable tool for language assessment because it draws upon a wide range of language processing skills.

Nonword-Repetition Ability Does Not Appear to Be a Causal Influence on Children’s Vocabulary Development

In the study reported here, we assessed the theory that vocabulary learning in children depends critically on the capacity of a “phonological loop” that is indexed by nonword-repetition ability. A 3-year longitudinal study of 219 children assessed nonword-repetition ability and vocabulary knowledge at yearly intervals between the ages of 4 and 7 years. There was a considerable degree of longitudinal stability in children’s vocabulary and nonword-repetition skills, but there was no evidence of any influence of nonword-repetition ability on later vocabulary knowledge. These results seriously call into question the claim that vocabulary learning in children is constrained by nonword-repetition ability, and they cast doubt on the broader theory that the phonological loop functions as a language-learning device.

Longitudinal relationships between language and verbal short-term memory skills in children with Down syndrome

Children with Down syndrome are at risk for language difficulties, the nature of which is not well understood. This study compared the longitudinal predictors of language skills in children with Down syndrome with those in typically developing control children matched for initial level of nonverbal mental ability. An age cohort of children with Down syndrome (n=43) and 57 typically developing control children was assessed on measures of vocabulary, grammar, and verbal short-term memory three times at yearly intervals. Children with Down syndrome showed slower development on all measures than the typically developing controls. Longitudinal analyses showed moderate to high stability of language and verbal short-term memory skills. Our results confirm earlier evidence of pervasive language learning difficulties in this group and suggest that early language intervention should be given high priority.

Spelling Development and Metalinguistic Training before School Entrance: The Effects of Different Metalinguistic Training on Spelling Development in First Grade

This paper presents the long term effects of two different metalinguistic intervention programs in kindergarten on spelling development. Experimental group 1 received a training program with activities that focused the children’s attention on the internal sound structure of words. Experimental group 2 received a training program with activities that focused the children’s attention on morphological parts of wards (e.g., prefixes, suffixes). A control group received no intervention but was regularly visited by the experimenter. Results from different metalinguistic pretests show that children with poorly educated mothers had the lowest scores before entering the experiment. The children received training 25 – 30 minutes weekly for a total period of 17 weeks. At the time of the pretest the age of the children was 5 years 10 months to 6 years 9 months. Both the group receiving metaphonological training and the group receiving metamorphological training benefited in terms of their spelling development. For the school measures, however, significant interactions between group and mother’s education suggested that children of poorly educated mothers profited the most from metaphonological training and that children with highly educated mothers profited the most from metamorphological training. Factor analysis of the pre-school measures shows that different linguistic and cognitive measures seems to contribute independently to spelling development. Some of the possible linguistic processes underlying the development of spelling are affected by metalinguistic training while others are not. Implications for teaching and therapy will be discussed.

Reading Development and Reading Disabilities: Focus on Norway

Literacy research in Norway has focused on many areas. Dyslexia has been one main area for many years. The last years’ many approaches have been taken to understand how reading disabilities can be prevented and to understand the connection between the spoken and written language. A school reform reducing the age of admission to school from seven to six from 1997 has had the effect of stimulating research in the field of reading development. Norwegian orthography is described as semi-transparent. Studies of Norwegian children show that even children with dyslexia break the alphabetic code rather easily. Also, Norway is an advanced, rich country with a clear commitment to equity. These are some reasons why Norway should get good results on international reading achievement tests. The results from different international reading assessments, however, have worried the Norwegian Government. The Organisation for Economic Cooperation and Development (OECD) has clearly stated that Norway has a job to do in terms of equity. In most reading achievement tests, Norway shows a wider spread of outcomes than many other OECD countries. The Norwegian school reform of 1997 has not been a great success in the area of childrens literacy development. The international results and the evaluation of the reform have led to a range of initiatives from the Government and to yet another reform with a new curriculum. In this new curriculum, there is a somewhat clearer focus on benchmarks to be achieved. There is, however, little concentration on what to do when children fall behind their peers for no apparent reason. The school authorities hope, however, that the initiatives that are taken will make a difference.

The profile of social functioning in children with Down syndrome.

Abstract Background: Practitioners and researchers have asserted for decades that social functioning is a strength in children with Down syndrome (DS). Nevertheless, some studies have concluded that children with DS may be at greater risk of impaired social functioning compared to typically developing controls. This cross-sectional study explores the profile of social functioning (social capabilities and social problems) in six-year-old children with DS, compares it with that of typically developing children and reveals possible differences in predictors between groups. Method: Parental reports and clinical tests were utilized. Results: The children with DS had generally weaker social capabilities compared to nonverbal mental age-matched controls, but no significant differences were found for social interactive play, community functioning and prosocial behaviour. No significant differences in predictors for social capabilities between the groups were found. The children with DS had more social problems than the typically developing controls with a similar chronological age and those with a similar nonverbal mental age, but no significant differences in emotional symptoms were found between the children with DS and either comparison group. Vocabulary was a more important predictor of social problems in the children with DS than in the typically developing control groups. Conclusion: Interventions for children with DS should strongly focus on integrating vocabulary skills and social functioning starting at an early age. Implications for Rehabilitation Children with Down syndrome need help and support in social functioning. Systematic training to optimize social capabilities and to prevent social problems should be prioritized. Structured and explicit learning of words important for social interaction with peers and for conflict solutions should be emphasized. Integrated interventions focusing on social functioning and vocabulary should begin in preschool to prepare children for participation in mainstream education.

Cognitive, linguistic, and contextual factors in Norwegian second language learner's narrative production

The present study investigated the contribution of cognitive, linguistic, and contextual factors to the narrative production of Norwegian second language learners. We assessed cognitive ability and first and second language proficiency in 66 kindergarten children with Urdu/Punjabi as their first language. Number of childrens books in the home and time spent in kindergarten were treated as contextual factors. Oral narration was assessed in Grade 1. A series of fixed-order hierarchical regression analyses displayed a complex relationship among cognitive, linguistic, and contextual factors and various facets of narrative production of young second language learners; nonverbal ability and books in the home predicted the mastering of story (macro)structure, while linguistic (vocabulary and grammar) and both contextual variables predicted microaspects of narrative proficiency. The results suggest that combining home book reading practices, kindergarten attendance, and second language interventions might improve language minority childrens narrative production and chances of school success.
