A few studies suggest that gifted children with dyslexia have better literacy skills than averagely intelligent children with dyslexia. This finding aligns with the hypothesis that giftedness-related factors provide compensation for poor reading. The present study investigated whether, as in the native language (NL), the level of foreign language (FL) literacy of gifted students with dyslexia is higher than the literacy level of averagely intelligent students with dyslexia and whether this difference can be accounted for by the difference in their NL literacy level. The sample consisted of 148 Dutch native speaking secondary school students divided in four groups: dyslexia, gifted/dyslexia, typically developing (TD), and gifted. All students were assessed on word reading and orthographic knowledge in Dutch and English when they were in 7th or 8th grade. A subsample (n = 71) was (re)assessed on Dutch, English, French, and German literacy one year later. Results showed that Dutch gifted students with dyslexia have higher NL literacy levels than averagely intelligent students with dyslexia. As in the NL, a stepwise pattern of group differences was found for English word reading and spelling, i.e., dyslexia < gifted/dyslexia < TD < gifted. However, it was not found for French and German literacy performance. These results point towards compensation: the higher English literacy levels of gifted/dyslexic students compared to their averagely intelligent dyslexic peers result from mechanisms that are unique to English as a FL. Differences in results between FLs are discussed in terms of variation in orthographic transparency and exposure. 相似文献

The study investigated cognitive deficits associated with dyslexia and familial risk of dyslexia (endophenotypes) by comparing children from families with and without a history of dyslexia. Eighty-eight school-aged children were assessed on measures of phonology, language and rapid automatized naming. A series of regression analyses with family risk and dyslexia status as predictors indicated that word recall, morphology, and rapid automatized naming were associated with the deficit, whereas the two phonological measures (phoneme awareness and nonword repetition) were associated with both literacy deficits and family risk, suggesting that the phonological deficit is an endophenotype of dyslexia. Whereas the association with familial risk was similar for the two phonological measures, they differed in their relation to dyslexia status: Phoneme awareness showed a stronger association with dyslexia than risk status, whereas nonword repetition was more strongly related to the risk. The data are interpreted within the framework of multiple deficit models of dyslexia. 相似文献

In four carefully selected samples of 8- to 10-year old children with dyslexia (but age adequate arithmetic skills), dyscalculia (but age adequate reading skills), dyslexia/dyscalculia and controls a domain-general deficit in rapid automatized naming (RAN) was found for both dyslexia groups. Dyscalculic children exhibited a domain-specific deficit in rapid naming of quantities. This finding is in line with recent assumptions that dyscalculia is associated with a neurobiological deficit in the processing of numerosities. In the dyslexia/dyscalculia group, RAN deficits were additive, that is, the dyslexia/dyscalculia group exhibited the sum of the deficits found in the dyslexia only and dyscalculia only groups. This finding suggests that the cognitive bases of dyslexia and dyscalculia are independent from each other. Within the naming speed paradigm no differential impact of special demands on the executive functions inhibition and shifting was found for any of the four groups. 相似文献

The present study sought to identify cognitive abilities that might distinguish Hong Kong Chinese adolescents with dyslexia and to assess how these abilities were associated with Chinese word reading, word dictation, and reading comprehension. The cognitive skills of interest were morphological awareness, visual-orthographic knowledge, rapid naming, and verbal working memory. A total of 90 junior secondary school students, 30 dyslexic, 30 chronological age controls, and 30 reading level controls was tested on a range of cognitive and literacy tasks. Dyslexic students were less competent than the control students in all cognitive and literacy measures. The regression analyses also showed that verbal working memory, rapid naming, morphological awareness, and visual-orthographic knowledge were significantly associated with literacy performance. Findings underscore the importance of these cognitive skills for Chinese literacy acquisition. Overall, this study highlights the persistent difficulties of Chinese dyslexic adolescents who seem to have multiple causes for reading and spelling difficulties. 相似文献

Recent studies have emphasized that developmental dyslexia is a multiple-deficit disorder, in contrast to the traditional single-deficit view. In this context, cognitive profiling of children with dyslexia may be a relevant contribution to this unresolved discussion. The aim of this study was to profile 36 Portuguese children with dyslexia from the 2nd to 5th grade. Hierarchical cluster analysis was used to group participants according to their phonological awareness, rapid automatized naming, verbal short-term memory, vocabulary, and nonverbal intelligence abilities. The results suggested a two-cluster solution: a group with poorer performance on phoneme deletion and rapid automatized naming compared with the remaining variables (Cluster 1) and a group characterized by underperforming on the variables most related to phonological processing (phoneme deletion and digit span), but not on rapid automatized naming (Cluster 2). Overall, the results seem more consistent with a hybrid perspective, such as that proposed by Pennington and colleagues (2012), for understanding the heterogeneity of dyslexia. The importance of characterizing the profiles of individuals with dyslexia becomes clear within the context of constructing remediation programs that are specifically targeted and are more effective in terms of intervention outcome. 相似文献

Participants were administered multiple measures of phonological awareness, oral language, and rapid automatized naming at the beginning of kindergarten and multiple measures of word reading at the end of second grade. A structural equation model was fit to the data and latent scores were used to identify children with a deficit in phonological awareness alone or in combination with other kindergarten deficits. Children with a deficit in phonological awareness in kindergarten were found to be five times more likely to have dyslexia in second grade than children without such a deficit. This risk ratio substantially increased with the addition of deficits in both oral language and rapid naming. Whereas children with one or more kindergarten deficits were at heighten risk for dyslexia, some of these children were found to be adequate or better readers. These results are discussed within a multifactorial model of dyslexia that includes both risk and protective factors. 相似文献

The present study was designed to examine the question of whether developmental dyslexia in 12-year-old students at the beginning
of secondary education in the Netherlands is confined to problems in the domain of reading and spelling or also is related
to difficulties in other areas. In particular, hypotheses derived from theories on phonological processing, rapid automatized
naming, working memory, and automatization of skills were tested. To overcome the definition and selection problems of many
previous studies, we included in our study all students in the first year of secondary special education in a Dutch school
district. Participants were classified as either dyslexic, garden-variety, or hyperlexic poor readers, according to the degree
of discrepancy between their word recognition and listening comprehension scores. In addition, groups of normal readers were
formed, matching the poor readers in either reading age or chronological age. A large test battery was administered to each
student, including phonological, naming, working memory, speed of processing, and motor tests. The findings indicate that
dyslexia is associated with deficits in (1) phonological recoding, word recognition (both in their native Dutch and in English
as a second language), and spelling skills; and (2) naming speed for letters and digits. Dyslexia was not associated with
deficits in other areas. The results suggest that developmental dyslexia, at the age of 12, might be (or might have become)
a difficulty rather isolated from deficiencies in other cognitive and motor skills. 相似文献

ABSTRACTThis study presents a meta-analytic review of serial rapid automatized naming (RAN) deficits in individuals with dyslexia relative to typical readers (based on 216 effect sizes comprising 8335 dyslexic readers, 14,083 age-matched controls, and 921 reading-matched controls). A random-effects model analysis indicated a large impairment in speeded RAN in individuals with dyslexia compared with age-matched controls (d = 1.19) but a similar performance when compared with reading-matched controls (d = 0.13). In addition, dyslexic readers presented a deficit in discrete-naming formats (d = 0.74), although the deficit in serial RAN was notably larger; hence, adding seriality is particularly detrimental for these readers. The deficit appears to span all stimulus types (alphanumeric and nonalphanumeric), indicating that processes beyond letter processing are responsible for the delays and are independent of set size. Poor RAN is a long-term and universal symptom of dyslexia, and the transparency of the writing system does not influence its severity. 相似文献

The home literacy environment (HLE) predicts language and reading development in typically developing children; relatively little is known about its association with literacy development in children at family-risk of dyslexia. We assessed the HLE at age 4 years, precursor literacy skills at age 5, and literacy outcomes at age 6, in a sample of children at family-risk of dyslexia (n = 116) and children with no known risk (n = 72). Developmental relationships between the HLE and literacy were comparable between the groups; an additional effect of storybook exposure on phoneme awareness was observed in the family-risk group only. The effects of socioeconomic status on literacy were partially mediated by variations in the HLE; in turn, effects of the HLE on literacy were mediated by precursor skills (oral language, phoneme awareness, and emergent decoding) in both groups. Findings are discussed in terms of possible gene–environment correlation mechanisms underpinning atypical literacy development. 相似文献

Path analysis was used to test the predictive and mediational role that self-efficacy beliefs play in the mathematical problem-solving of middle school gifted students (n= 66) mainstreamed with regular education students (n= 232) in algebra classes. Self-efficacy of gifted students made an independent contribution to the prediction of problem-solving in a model that controlled for the effects of math anxiety, cognitive ability, mathematics GPA, self-efficacy for self-regulated learning, and sex. Gifted girls surpassed gifted boys in performance but did not differ in self-efficacy. Gifted students reported higher math self-efficacy and self-efficacy for self-regulated learning as well as lower math anxiety than did regular education students. Although most students were overconfident about their capabilities, gifted students had more accurate self-perceptions and gifted girls were biased toward underconfidence. Results support the hypothesized role of self-efficacy in A. Bandura's (1986) social cognitive theory. 相似文献

Abstract A subset of the corpus of gifted students who have learning difficulties are those who have specific literacy disabilities; gifted literacy disabled (GLitD) students. Estimates suggest that approximately 10 per cent gifted read at a level of two or more years below their expected grade level. Surprisingly then, these students have attracted comparatively little past research interest. The present investigation examined the reading characteristics of a group of 37 primary level GLitD students aged between 78 and 121 months. These students displayed a discrepancy in literacy perfor‐mance of at least 1 standard deviation below the mean for their chronological age in at least one of reading prose accuracy, prose reading com‐prehension or isolated word reading accuracy. As well, their spelling and phonemic awareness (segmentation and blending) were assessed. Scores on the cognitive factors of the W1SC‐III identified two groups: a group of 20 students with superior performance (at least 130 points) on both Verbal Comprehension and Perceptual Organisation (the ‘superior VC + PO’ group) and a group of 17 students with superior performance only on Perceptual Organisation (the ‘superior PO’ group). The two groups differed in the literacy patterns displayed. The superior PO group showed the greater level of difficulty, with all measures of literacy at least one standard deviation below their expected score. The superior VC + PO group showed lower performance on isolated word reading and spelling. They did not differ in phonemic awareness. The literacy disability displayed by both groups is attributed to a specific preference for the use of global rather than analytic information processing strategies. This in turn influences phonemic awareness knowledge and consequently orthographic knowledge. The superior VC + PO group are more able to compensate for this cognitive disability. The implications of this study for the diagnosis and instruction of GLitD students are discussed. 相似文献

Primary school teachers rated the frequency of occurrence of 65 reading-related behavioral characteristics of Grade 1 to Grade
6 Chinese school children in Hong Kong. An item factor analysis based on ratings on 554 students yielded two major dimensions
of behavioral characteristics on reading and writing problems, and sequencing and spatial difficulties. In predicting the
literacy and cognitive skills of a separate sample of 184 school children, gender, age, and the two empirical scales developed
on the basis of factor analysis were used as predictors in regression analyses. The findings indicated that reading and writing
problems emerged as the most predominant predictor of various literacy and cognitive deficits. The two mean scores of behavioral
characteristics for children with dyslexia were significantly elevated as compared with those for children without dyslexia.
Implications of the findings for screening dyslexia and predicting specific cognitive deficits using classroom-based behavior
checklists are discussed. 相似文献

This study examined strategic variability and variability-performance relations in intellectually gifted (mean IQ = 142.31; n = 85) and non-gifted (mean IQ = 112.44; n = 81) children who received five trials on an organizational memory task. Children were presented with different sets of categorizable words (e.g., boat, bus, car, banana, apple, orange) on each trial and were asked to remember the words for later recall. Four strategies were coded on each trial: sorting at study, rehearsal, category naming, and clustering at recall. Strategic variability was assessed in terms of fluctuations in the use of single strategies over trials, use of different combinations of multiple strategies over trials, and trial-bytrial switches in strategy use. In general, gifted children showed lower levels of variability (or higher levels of stability) in strategy use and higher levels of recall than non-gifted children. In addition, stability in strategy use was consistently associated with relatively high levels of recall for gifted but not non-gifted children. These findings confirm and extend research on non-strategic elementary cognitive tasks showing that cognitive stability is a prominent characteristic of gifted cognition. 相似文献

The prevalence of phonological and surface dyslexia subtypes among Swedish university students with dyslexia (n = 40) was examined using both the regression method, developed by Castles and Coltheart, and latent profile analysis. When an academic‐level control group was used as a reference group in a regression, eight students with phonological dyslexia and 15 students with surface dyslexia were identified. In contrast, 17 students with phonological dyslexia and two students with surface dyslexia were identified when the subtypes were defined by reference to a reading‐level control group, indicating a deviant profile among the students with phonological dyslexia and delayed development among those with surface dyslexia. The latent profile analysis was based on five phonological and four orthographic tasks. Seven profiles were obtained, of which none exhibited deficits in orthographic but not in phonological skills or vice versa. Thus, the analysis further supported the phonological deficit hypothesis of dyslexia. 相似文献

The present study investigated the persistent nature of naming speed deficits within the context of the double-deficit hypothesis in a university sample of adults with reading disabilities (RD). Twenty-five university students with RD were compared to 28 typically achieving readers on measures of reading skill, phonological processing, and naming speed. The results indicated that both naming speed and phonological processing deficits characterized the RD group. In a regression analysis, neither naming speed nor phonological processing were important variables in explaining comprehension when reading rate was in the model. The results of the present study are mixed at best and are consistent with earlier conclusions that support for the double-deficit hypothesis of dyslexia remains limited. 相似文献

AbstractThis study explored the relative salience of students’ personal strengths and teacher support in predicting academic risk status. The participants were Secondary One (S1, Grade Seven) students from Singapore who scored below the cohort’s mean score in a national test administered at the end of primary education, and were identified as low risk (n = 309) or high risk (n = 396), based on their S1 achievement score in the English Language subject. Logistic regression analysis was conducted with academic risk status as criterion variable and the following potential predictors: students’ background variables (i.e. socio-economic status, cognitive ability and initial achievement), personal strengths, teacher–student relatedness, and teacher autonomy and competence support. After controlling for the effects of the students’ background variables, teacher trust emerged as the strongest (negative) and most stable predictor of high-risk status; teacher alienation and teacher–student communication were found as significant positive predictors of students’ placement in the high-risk group. 相似文献

The double-deficit hypothesis of developmental dyslexia proposes that deficits in phonological processing and naming speed represent independent sources of dysfunction in dyslexia. The present article is a review of the evidence for the double-deficit hypothesis, including a discussion of recent findings related to the hypothesis. Studies in this area have been characterized by variability in methodology--how dyslexia is defined and identified, and how dyslexia subtypes are classified. Such variability sets limitations on the extent to which conclusions may be drawn with respect to the double-deficit hypothesis. Furthermore, the literature is complicated by the persistent finding that measures of phonological processing and naming speed are significantly correlated, resulting in a statistical artifact that makes it difficult to disentangle the influence of naming speed from that of phonological processing. Longitudinal and intervention studies of the double-deficit hypothesis are needed to accumulate evidence that investigates a naming speed deficit that is independent of a phonological deficit for readers with dyslexia. The existing evidence does not support a persistent core deficit in naming speed for readers with dyslexia. 相似文献

The term “intellectually gifted rural-to-urban migrant children” refers to intellectually gifted children who are in migration from rural to urban areas. We compared performances on seven attention tasks among intellectually gifted (n = 26) and average (n = 30) rural-to-urban migrant and intellectually gifted urban children (n = 31). Our results showed that intellectually gifted rural-to-urban migrant children performed more correctly and faster on some attention tasks than did the intellectually average rural-to-urban migrant children, but they did not perform as well on some attention tasks as did the intellectually gifted urban children. Based on the attentional structures, it was evident the intellectually gifted rural-to-urban migrant children developed more mature than did either the intellectually gifted urban or the intellectually average rural-to-urban migrant children. This suggests the intellectually gifted rural-to-urban migrant children’s attention is overall superior to that of their intellectually average peers. However, there are advantages and disadvantages in terms of the quality of their attention compared to the intellectually gifted urban children. While their attentional structures seem to develop earlier, their accuracy on some of the attention tasks seems to suffer. This suggests that rural-to-urban migration is a double-edged sword for intellectually gifted children. 相似文献

We examined cognitive attributes, attention, and self‐efficacy of fourth grade struggling readers who were identified as adequate responders (n = 27), inadequate responders with comprehension only deficits (n = 46), and inadequate responders with comprehension and word reading deficits (n = 52) after receiving a multicomponent reading intervention. We also included typical readers (n = 40). These four groups were compared on measures of nonverbal reasoning, working memory, verbal knowledge, listening comprehension, phonological awareness, and rapid naming as well as on teacher ratings of attention problems and self‐reported self‐efficacy. The two inadequate responder groups demonstrated difficulties primarily with verbal knowledge and listening comprehension compared to typical readers and adequate responders. Phonological awareness and rapid naming differentiated the two inadequate responder groups. In addition, both inadequate responder groups showed more attention problems and low self‐efficacy compared to typical readers. 相似文献

The double-deficit hypothesis of dyslexia posits that reading deficits are more severe in individuals with weaknesses in phonological awareness and rapid naming than in individuals with deficits in only one of these reading composite skills. In this study, the hypothesis was tested in an adult sample as a model of reading achievement. Participants were parents of children referred for evaluation of reading difficulties. Approximately half of all participants reported difficulty learning to read in childhood and a small subset demonstrated ongoing weaknesses in reading. Structural equation modeling results suggest that the double-deficit hypothesis is an accurate model for understanding adult reading achievement. Better reading achievement was associated with better phonological awareness and faster rapid automatized naming in adults. Posthoc analyses indicated that individuals with double deficits had significantly lower reading achievement than individuals with single deficits or no deficits. 相似文献
