Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (Ncases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions. 相似文献

This paper reviews current proposals concerning the definition of dyslexia and contrasts it with reading comprehension impairment. We then discuss methods for early identification and review evidence that teacher assessments and ratings may be valid screening tools. Finally, we argue that interventions should be theoretically motivated and evidence based. We conclude that early identification of children at risk of dyslexia followed by the implementation of intervention is a realistic aim for practitioners and policy‐makers. 相似文献

The authors report a short-term reading intervention study involving 15 children with Down syndrome (DS) who attended mainstream
schools. The intervention programme taught children phoneme segmentation and blending skills in the context of learning letter-sounds
and working with words in books. The children were taught by their learning support assistants, who received special training
for this purpose. Compared to a waiting group, a group of eight children with DS improved significantly on measures of early
literacy skills (letter-sound knowledge, Early Word Recognition) following eight weeks of intervention. The waiting group
started to make progress once they received the intervention. Both groups maintained progress on the literacy measures five
months after the intervention had finished. The results suggest that children with DS can benefit from structured, phonics-based
reading intervention. 相似文献

The home literacy environment is a well-established predictor of children’s language and literacy development. We investigated whether formal, informal, and indirect measures of the home literacy environment predict children’s reading and language skills once maternal language abilities are taken into account. Data come from a longitudinal study of children at high risk of dyslexia (N = 251) followed from preschool years. Latent factors describing maternal language were significant predictors of storybook exposure but not of direct literacy instruction. Maternal language and phonological skills respectively predicted children’s language and reading/spelling skills. However, after accounting for variations in maternal language, storybook exposure was not a significant predictor of children’s outcomes. In contrast, direct literacy instruction remained a predictor of children’s reading/spelling skills. We argue that the relationship between early informal home literacy activities and children’s language and reading skills is largely accounted for by maternal skills and may reflect genetic influences. 相似文献

This paper reports 3 studies comparing thereading and phonological skills of childrenwith Down syndrome (DS) and younger normallydeveloping children of similar reading level.In Study 1, the two groups did not differ insight word or nonword reading, but the childrenwith DS did marginally less well on syllablesegmentation, rhyme and phoneme detectiontasks. Group differences in syllable andphoneme awareness appeared attributable todifferences in verbal ability (BPVS, vocabularyknowledge); however, a significant impairmentin rhyme detection remained in an analysis ofsub-groups equated in vocabulary knowledge. Thedeficit in rhyme observed in DS was replicatedin Studies 2 and 3 using simplified tests ofrhyme judgement, with the majority of childrenwith DS performing at chance on the rhymemeasures. In contrast, the two groups did notdiffer in their ability to detect phonemes inany of the 3 studies and performed above chancein initial phoneme detection and alliterationjudgement tasks, although the identification offinal phonemes was at a much lower level. Correlational analyses indicated a relationshipbetween phonological skills and reading inboth groups. However, for children with DS,letter-sound knowledge did not predict readingwhereas it did for normal controls. It issuggested that children with DS do not possessfull phoneme awareness; although they canidentify initial phonemes in words, they do notunderstand phoneme invariance and may rely lesson phonological skills for reading thancontrols. 相似文献

This paper reports two experiments which focus on the object naming deficits of dyslexic readers. In Experiment 1, dyslexic and normal readers were asked to name objects depicted by pictures or following their spoken definition. Ten-year-old dyslexics named fewer objects correctly than other children of a similar age, performing only as well as a younger group of 8-year-old normal readers. This was true irrespective of the modality through which they were tested. In terms of naming latency, however, they were similar to comparison groups. In Experiment 2, nine-year-old dyslexic and normal readers performed as well as each other in a receptive vocabulary test in which pictures had to be matched to spoken words. However, once again, on a picture naming test, the dyslexics did less well than controls. We argue that dyslexic children are subject to verbal naming difficulties which cannot be accounted for by generally low levels of vocabulary knowledge. Their problems are attributable not to difficulties in semantic representation but to difficulties with the lexical-phonological representation of spoken words they know. We propose that, in turn, these difficulties are related to their memory and reading problems. 相似文献

On the validity and sensitivity of the phonics screening check: erratum and further analysis 
下载免费PDF全文
下载免费PDF全文 Duff, Mengoni, Bailey and Snowling (Journal of Research in Reading, 38: 109–123; 2015) evaluated the sensitivity and specificity of the phonics screening check against two reference standards. This report aims to correct a minor data error in the original article and to present further analysis of the data. The methods used are calculation of predictive values of the phonics screening check in addition to sensitivity and specificity, and evaluation of agreement between the reference tests. Predictive values are important indicators of screening test quality. The positive predictive value of the phonics check is low (0.31) when compared with a standardised reading test but high (0.84) when compared with teachers' phonic phases judgements, reflecting poor agreement (kappa = 0.27) between reference tests. Results have implications for practice in terms of choice of reference standard and choice of threshold criterion for children to pass the screening check. Longitudinal data are needed to assess the predictive validity and utility of the check. What is already known about this topic:
- The importance of phonics in learning to read is widely acknowledged.
- The phonics screening check was introduced into U.K. schools in 2012 to ensure that all children develop phonic decoding skills.
- Estimates of the sensitivity and specificity of the phonics screening check, compared with two established ‘reference’ measures, were reported by Duff et al. ( 2015 ).
- We correct a minor error in the report of the original data by Duff et al. ( 2015 ).
- We draw attention to the importance of including predictive values, alongside sensitivity and specificity, in the evaluation of screening test validity. We also propose an alternative statistic for comparing the two reference measures.
- We show that applying this further analysis to the data in Duff et al. ( 2015 ) reveals the following: (i) the numbers of incorrect (false positive and false negative) outcomes in the phonics check and (ii) the marked difference in these numbers depending on the choice of reference measure.
- Reports of screening test validity should include positive and negative predictive values.
- A fundamental consideration for evaluating the validity of the phonics screening check is the choice of reference measure.
- Longitudinal data are needed to assess the predictive validity and utility of the phonics check.

We report the findings of a follow-up study of 34 9-year-old children who had participated in a longitudinal study of phonological and literacy development between the ages of 4 and 6 years. In a series of concurrent and longitudinal analyses, measures of phoneme awareness proved to be better predictors of spelling than measures of rime awareness. Children's awareness of grammatical relations influenced their orthographic skills in spelling. Although we were able to demonstrate that later orthographic knowledge is influenced by earlier phonological processes, our results are also consistent with the view that awareness of grammatical rules has an important role in determining orthographic proficiency as children get older. 相似文献
