The present study examined the etiology of highreading ability in an overall sample of 350twin pairs in which at least one member of 100pairs (54 MZ, 46 DZ) had a reading compositescore one standard deviation above the sample mean. These highreaders also had significantly higher scoresthan the rest of the sample on Full Scale,Verbal and Performance IQ scores, as well as onmeasures of phoneme awareness, orthographiccoding, phonological decoding, and verbalshort-term memory. The MZ proband-wiseconcordance rate for high group membership wassignificantly higher than the DZ proband-wiseconcordance rate and further behavioralgenetic analyses corroborated that high readingability is partly due to genetic influence(h2
g = 0.55 ± 0.22). Bivariatemultiple regression analyses demonstrated thathigh phonological awareness, orthographiccoding, phonological decoding, and short-termverbal memory skills all share significantcommon genetic influence with high readingability. These results suggest that readingability and its cognitive correlates are on acontinuous distribution, with both extremes ofthe distribution being similarly heritable. They also support the hypothesis that the samecognitive processes that are associated withdyslexia are important for the development ofhigh reading ability. 相似文献

The DigitalHub scholarly repository was developed and launched at the Galter Health Sciences Library for the Feinberg School of Medicine and the greater Northwestern Medicine community. The repository was designed to allow scholars the ability to create, share, and preserve a range of citable digital outputs. This article traces the evolution of DigitalHub’s development and engagement activities, highlighting project challenges, innovations, success stories, and the team-based approach that was employed to successfully achieve project goals. 相似文献

Specific deficits in component reading and language skills: genetic and environmental influences 总被引:29,自引:0,他引:29
Phonological coding, measured by the oral reading of nonwords, and orthographic coding, measured by the discrimination of words from homophonic nonwords (e.g., rane, rain), were compared for pairs of older children with reading disabilities (RD) and younger nondisabled readers matched on word recognition. Phonological coding was substantially lower for most children with RD, indicating a unique developmental deficit in phonological coding rather than an equal developmental lag across all component reading skills. Data from identical and fraternal twins indicated that the phonological coding deficit of the children with RD was highly heritable and accounted for most of the heritable variance in their word recognition deficits. The deficits of the twins with RD in segmental language skills (rhyming and phoneme segmentation) were related to the heritable variance in their phonological coding deficits. Orthographic coding was not significantly heritable, and it accounted for much of the environmental variance in word recognition deficits. Implications of the results for the remediation of reading disability are discussed. 相似文献

This qualitative study examined the experiences of counsellors and their perceptions of resources that helped them cope with traumatized clients and difficult client sessions. The research was conducted using in-depth interviews with a purposive sample of eight counsellors working in five counselling agencies. The study identified how counsellors develop their own personal and professional strategies for coping with challenge, and the supportive structures and coping strategies provided by agencies. From these counsellors’ stories of learning to cope with traumatized clients and traumatic material, we highlight some recommendations that may facilitate the development of effective coping strategies for the prevention or amelioration of vicarious traumatization. 相似文献

Recent research has raised the question of whether age- and IQ-discrepancy forms of reading disability (RD) are distinguishable in terms of either their underlying linguistic deficit or their response to treatment, thus threatening the external validity of the traditional distinction between specific reading retardation and reading backwardness. The present study pursued the external validity of this distinction in three domains: (a) genetic etiology, (b) sex ratio and clinical correlates, and (c) neuropsychological profiles. Each of these domains was explored in the RD (n = 640) and control (n = 436) twins participating in the Colorado Reading Project (514 males, 562 females, with an overall mean age of 12.42 years). Little evidence for external validity was found in terms of the clinical correlates of attention deficit-hyperactivity disorder (ADHD), immune disorders, or handedness. Most importantly, there was no evidence of differential genetic etiology of the two phenotypes in this sample, in that deficits in both phenotypes were similarly heritable (h2g = .40 and .46 for age and IQ phenotypes, respectively) and the genetic correlation between them was high (rG = .88 to .96). However, the genetic and neuropsychological profile analyses did suggest that age- and IQ-discrepancy definitions of RD may relate differentially to component reading processes, such as phonological awareness and orthographic coding. 相似文献

There is considerable interest in the potential non‐musical cognitive and academic benefits of music listening and instruction to children. This report describes three lines of research relevant to this issue, namely, the effects of: (1) focused music listening on subsequent task performance (the Mozart effect); (2) music instruction; and (3) background music listening. Research suggests that while Mozart effect studies have attracted considerable media attention, the effect cannot be reliably demonstrated in children. In contrast, music instruction confers consistent benefits for spatiotemporal reasoning skills; however, improvements in associated academic domains, such as arithmetic, have not been reliably shown. Finally, background music may calm and focus children with special education needs, thereby enhancing learning. Additional research is required to determine whether this effect is evident in normal populations. Overall, evidence for the non‐musical benefits of music listening and instruction is limited. The inherent value of music and music education should not be overlooked by narrowly focusing on cognitive and academic outcomes. 相似文献

In this article the author presents ways in which one problem in intergroup relations may be handled by writers of Protestant church school materials. This is based on his intensive analysis of curriculum materials for their intergroup content in the Yale Intergroup Research Project. 相似文献
