Not every child seems equally susceptible to the same parental, educational, or environmental influences even if cognitive level is similar. This study is the first randomized controlled trial to apply the differential susceptibility paradigm to education in relation to children's genotype and early literacy skills. A randomized pretest–posttest control group design was used to examine the effects of the Intelligent Tutoring System Living Letters. Two intervention groups were created, 1 receiving feedback and 1 completing the program without feedback, and 1 control group. Carriers of the long variant of the dopamine D4 receptor gene (DRD4 7‐repeat) profited most from the computer program with positive feedback, whereas they performed at the lowest level of early literacy skills in the absence of such feedback. Our findings suggest that behind modest overall educational intervention effects a strong effect on a subgroup of susceptible children may be hidden. 相似文献

Not all young children benefit from book exposure in preschool age. It is claimed that the ability to hold information in
mind (short-term memory), to ignore distraction (inhibition), and to focus attention and stay focused (sustained attention) may have a moderating effect on children’s reactions to the home literacy environment. In a group of 228 junior kindergarten
children with a native Dutch background, with a mean age of 54.29 months (SD = 2.12 months), we explored therefore the relationship
between book exposure, cognitive control and early literacy skills. Parents filled in a HLE questionnaire (book sharing frequency
and an author recognition checklist as indicator of parental leisure reading habits), and children completed several tests
in individual sessions with the researcher (a book-cover recognition test, PPVT, letter knowledge test, the subtests categories
and patterns of the SON, and cognitive control measures namely digit span of the KABC, a peg tapping task and sustained attention
of the ANT). Main findings were: (1) Children’s storybook knowledge mediated the relationship between home literacy environment
and literacy skills. (2) Both vocabulary and letter knowledge were predicted by book exposure. (3) Short-term memory predicted
vocabulary over and above book exposure. (4) None of the cognitive control mechanisms moderated the beneficial effects of
book exposure. 相似文献

Living Letters is an adaptive game designed to promote children??s combining of how the proper name sounds with their knowledge of how the name looks. A randomized controlled trial (RCT) was used to experimentally test whether priming for attending to the sound-symbol relationship in the proper name can reduce the risk for developing reading problems in the first two grades of primary education. A Web-based computer program with more intensive practice than could be offered by teachers affords activities that prompt young children to pay attention to print as an object of investigation. The study focused on a sub-sample of 110 five-year-old Dutch children from 15 schools seriously delayed in code-related knowledge. Outcomes support the need for early remedial computer programs, and demonstrate that, without a brief but intensive treatment, more children from the at-risk group lack the capacity to benefit from beginning reading instruction in the early grades. With an early intervention in kindergarten, children with code-related skills delays gained about half a standard deviation on standardized tests at the end of grade 2. 相似文献

How can be explained that early literacy and numeracy share variance? We specifically tested whether the correlation between four early literacy skills (rhyming, letter knowledge, emergent writing, and orthographic knowledge) and simple sums (non-symbolic and story condition) reduced after taking into account preschool attention control, short-term memory, speed of processing, visual-spatial skills, vocabulary, and shared book reading. 228 Dutch native preschoolers (mean age 54.25; SD = 2.12 months) participated. The results revealed that 1) all literacy skills were related to sums (non-symbolic and story condition), 2) rhyming was the strongest predictor of non-symbolic sums, and letter knowledge of sums in story context, 3) visual-spatial skills explained part of the shared variance in the non-symbolic condition and visualspatial skills, vocabulary and short-term memory explained part of the shared variance in sums in story context. Implications for the preschool curriculum and early interventions are discussed. 相似文献

This study explored longitudinal associations between early shared reading at 2 to 3 years of age and children’s later academic achievement. It examined the mediating role of children’s vocabulary and early academic skills, and the moderating effects of family’s socioeconomic status. Data were drawn from the Longitudinal Study of Australian Children (n = 4,768). Academic achievement was assessed at 8 to 9 years of age via standardized national test scores of literacy and mathematics achievement. Results indicated that early shared reading was associated with children’s academic achievement directly and indirectly through receptive vocabulary and early academic skills. Also, the frequency of early shared reading predicted the outcome measures, over and above other home learning activities. Associations were stronger among low and middle socioeconomic status groups compared to the high socioeconomic status group. We conclude that shared reading offers unique opportunities for adults to teach young children new words and concepts. 相似文献

Does alphabetic-phonetic writing start with the proper name and how does the name affect reading and writing skills? Sixty 4- to 5½-year-old children from middle SES families with Dutch as their first language wrote their proper name and named letters. For each child we created unique sets of words with and without the child’s first letter of the name to test spelling skills and phonemic sensitivity. Name writing correlated with children’s knowledge of the first letter of the name and phonemic sensitivity for the sound of the first letter of the name. Hierarchical regression analysis makes plausible that both knowledge of the first letter’s name and phonemic sensitivity for this letter explain why name writing results in phonetic spelling with the name letter. Practical implications of the findings are discussed. 相似文献

Research findingsThe study focused on 90 five-year-olds from fifteen Dutch schools. The children scored among the 30% lowest on literacy tests. Half were randomly assigned to a phonological skills program on the computer, the other half to a book program. Both programs consisted of 15 ten-minute sessions. During the phonological skills program children's mouse behavior was registered every tenth of a second. Intelligence, phoneme skills, and regulatory skills were tested. Children scoring average on regulatory skills benefited from teacher-free encounters with the phonological skills program, children scoring low or high did not. Typically, the lowest-scoring children showed more meaningless mouse activity and more random clicking.Practice or policyComputer programs can be used to stimulate early phoneme skills of poorly performing kindergarten children, but not for all children. Children with poor regulatory skills did not benefit from the intervention program. 相似文献

Even though the acquisition of early literacy skills obviously depends on stimuli and incentives in children’s environment
we may expect that genes define the constraints for acquiring some or all early literacy skills. Therefore behavior genetic
analyses were carried out on twin data including 27 identical and 39 same sex dizygotic twins, 4 years old. We focused on
a series of early literacy skills selected because they are developing in the focal age range: writing the proper name and
mama, rhyming, and alphabetic knowledge. The data for each skill were subjected to structural equation modeling. First, it
turned out that even in this young group genetic differences are the primary force in shaping early developing writing skills.
Second, bivariate analyses showed that similar environmental and genetic influences are involved across various skills. Third,
from secondary analyses on the available twin studies on early literacy it was apparent that the findings of this small-scaled
study correspond to outcomes of other large-scale twin studies. 相似文献
