Children showing poor executive functioning may not fully benefit from learning experiences at home and school and may lag behind in literacy skills. This hypothesis was tested in a sample of 276 kindergarten children. Executive functions and literacy skills were tested at about 61?months and again a year later. In line with earlier studies, correlations between both skills were significant at age 5?years, but the predictive value of executive functions on alphabetic skills weakened or disappeared 1?year later. Assuming that executive functions are in development at this age and change has to be taken into account, we applied fixed effects analyses (FEAs) to repeated measures of alphabetic skills and executive functions. FEAs demonstrated that changes in children's alphabetic skills concur with changes in executive functions, thus strengthening inferences about a causal relationship. Executive functions are unstable in the early stages of cognitive development and one-time measures cannot predict their impact on reading 1?year later. Consequences of this new insight are discussed.

Novel word learning is reported to be problematic for children with severe language impairments (SLI). In this study, we tested electronic storybooks as a tool to support vocabulary acquisition in SLI children. In Experiment 1, 29 kindergarten SLI children heard four e-books each four times: (a) two stories were presented as video books with motion pictures, music, and sounds, and (b) two stories included only static illustrations without music or sounds. Two other stories served as the control condition. Both static and video books were effective in increasing knowledge of unknown words, but static books were most effective. Experiment 2 was designed to examine which elements in video books interfere with word learning: video images or music or sounds. A total of 23 kindergarten SLI children heard 8 storybooks each four times: (a) two static stories without music or sounds, (b) two static stories with music or sounds, (c) two video stories without music or sounds, and (d) two video books with music or sounds. Video images and static illustrations were equally effective, but the presence of music or sounds moderated word learning. In children with severe SLI, background music interfered with learning. Problems with speech perception in noisy conditions may be an underlying factor of SLI and should be considered in selecting teaching aids and learning environments.

Background: The dopamine D4 receptor gene (DRD4) has been linked to attention deficit hyperactivity disorder (ADHD) and reading disorders. In this study, we examined whether diminished anticipatory dopamine cell firing--typical of the long variant of the DRD4 allele--is related to emergent and advanced alphabetic skills, and whether executive attention is a mediator between this allele and alphabetic skills. Method: We tested alphabetic skills in a normative sample of 159 children in both kindergarten and Grade 1, and executive attention 1 year earlier. Cheek cells were collected and genomic DNA was isolated from the samples using the Chemagic buccal swab kit on a chemagen Module I workstation. Results: Thirty-seven percent of the children were carriers of at least one DRD4 7-repeat allele. Carriers of the long variant scored lower on alphabetic skills, and executive attention appeared to be a mediator of the relation between characteristics of DRD4 and alphabetic skills in kindergarten and first grade. Conclusion: This study shows how a genetic factor which has been shown to relate to variation in attention and regulatory behavior can explain delays in alphabetic skills. A practical implication is that in many cases early interventions should not only target reading skills, but also support children's engagement in tasks. (Contains 3 tables and 1 figure.)

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. (Contains 1 figure and 5 tables.)

In a randomized control trial, the authors tested whether short- and long-term effects of an early literacy intervention are moderated by mild perinatal adversities in accordance with differential susceptibility theory. One-hundred 5-year-old children (58% male) who scored at or below the 30th percentile on early literacy measures were randomized to a Web-based remedial early literacy program Living Letters or a treated control group. Parents gave written informed consent to access the perinatal data of their children at the Perinatal Register in the Netherlands. Twenty-one children were, at birth, small for gestational age (between the 2.5th and 10th percentiles) or late preterm (between 34 and 37 weeks, 6 days). In this group with mild perinatal adversities, intervention children outperformed the control group immediately after the intervention and after 8 months of formal reading instruction, but a similar effect of the computerized literacy program in children without mild perinatal adversities was absent. In line with the theory of differential susceptibility, children with mild perinatal adversities seem to be more open to environmental input, for better "and" for worse.

The goals of this study were to examine (a) whether extratextual vocabulary instructions embedded in electronic storybooks facilitated word learning over reading alone and (b) whether instructional formats that required children to invest more effort were more effective than formats that required less effort. A computer-based "assistant" was added to electronic storybooks. The assistant posed extratextual vocabulary questions. Questions were presented in a multiple-choice format so that children could respond by clicking on the picture that best represented the target word. In Experiment 1 (N = 20), children read stories with and without questions. Children learned more words when reading with questions than without. Expressive vocabulary was particularly affected by question insertion. In Experiment 2 (N = 27), we used two methods for teaching words: one requiring more effort on the part of children (questions) and one requiring less effort ("hotspots" that provide definitions). Results revealed that questions were more beneficial than just providing a definition or synonym of the target word. Implications for designing new e-book apps are discussed.

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. (Contains 4 tables.)

This research synthesis examines whether the association between print exposure and components of reading grows stronger across development. We meta-analyzed 99 studies (N = 7,669) that focused on leisure time reading of (a) preschoolers and kindergartners, (b) children attending Grades 1-12, and (c) college and university students. For all measures in the outcome domains of reading comprehension and technical reading and spelling, moderate to strong correlations with print exposure were found. The outcomes support an upward spiral of causality: Children who are more proficient in comprehension and technical reading and spelling skills read more; because of more print exposure, their comprehension and technical reading and spelling skills improved more with each year of education. For example, in preschool and kindergarten print exposure explained 12% of the variance in oral language skills, in primary school 13%, in middle school 19%, in high school 30%, and in college and university 34%. Moderate associations of print exposure with academic achievement indicate that frequent readers are more successful students. Interestingly, poor readers also appear to benefit from independent leisure time reading. We conclude that shared book reading to preconventional readers may be part of a continuum of out-of-school reading experiences that facilitate children's language, reading, and spelling achievement throughout their development.

This meta-analysis examines to what extent interactive storybook reading stimulates two pillars of learning to read: vocabulary and print knowledge. The authors quantitatively reviewed 31 (quasi) experiments (n = 2,049 children) in which educators were trained to encourage children to be actively involved before, during, and after joint book reading. A moderate effect size was found for oral language skills, implying that both quality of book reading in classrooms and frequency are important. Although teaching print-related skills is not part of interactive reading programs, 7% of the variance in kindergarten children's alphabetic knowledge could be attributed to the intervention. The study also shows that findings with experimenters were simply not replicable in a natural classroom setting. Further research is needed to disentangle the processes that explain the effects of interactive reading on children's print knowledge and the strategies that may help transfer intervention effects from researchers to children's own teachers.

This research focuses on the ability of book-based animated stories, when well designed and produced, to have positive effects on young viewers' narrative comprehension and language skills. Sixty 5-year-olds, learning Dutch as a 2nd language, were randomly assigned to 4 experimental and 2 control conditions. The children profited to some extent from repeated encounters with a storybook with static pictures but more from repeated encounters with the animated form of the story. Both story formats were presented on a computer screen; both included the same oral text spoken in the same voice but the animated story was supplemented with multimedia features (video, sounds, and music) dramatizing the events. Multimedia additions were especially effective for gaining knowledge of implied elements of stories that refer to goals or motives of main characters, and in expanding vocabulary and syntax. The added value of multimedia books was strengthened over sessions. In a group from families with low educational levels who were lagging in language and literacy skills, multimedia storybooks seem to provide a framework for understanding stories and remembering linguistic information.

A counterbalanced, within-subjects design was carried out to study the efficacy of electronic books in fostering kindergarten children's emergent story understanding. The study compared effects of children's independent reading of stories electronically with effects of printed books read aloud by adults. Participants were 18 four- to five-year-old Dutch kindergarten children in the initial stages of developing story comprehension but beyond just responding to pictures. Electronic reading produced experiences and effects similar to adult-read printed books. Children frequently interacted with the animations often embedded in electronic stories, but there was no evidence that the animations distracted children from listening to the text presented by electronic books, nor that the animations interfered with story understanding. Findings suggested that children at this stage of development profited from electronic books at least when electronic books are read in a context where adults also read books to children.

In a within-participant design, 41 children (mean age = 64 months, range = 50–81) listened to brief stories in four conditions. Written text was present on the screen in all conditions (similar to the typical storybook experience) but combined with other sources of information: (a) only oral narration, (b) oral narration and a picture that was congruent with the narration, (c) oral narration and an incongruent picture, and (d) only a picture but no oral narration. Children’s eye movements while looking at the screen were recorded with an eye-tracker. An important finding was that a congruent picture contributed substantially to children’s story retellings, more so than a picture that was incongruent with the narration. The eye-tracking data showed that children explored pictures in a way that they could maximally integrate the narration and the picture. Consequences for interactive reading and picture storybook format are discussed. [ABSTRACT FROM AUTHOR]

In this randomized controlled trial, 508 5-year-old kindergarten children participated, of whom 257 were delayed in literacy skills because they belonged to the lowest quartile of a national standard literacy test. We tested the hypothesis that some children are more susceptible to school-entry educational interventions than their peers due to their genetic makeup, and thus whether the dopamine receptor D4 gene moderated intervention effects. Children were randomly assigned to a control condition or one of two interventions involving computer programs tailored to the literacy needs of delayed pupils: Living Letters for alphabetic knowledge and Living Books for text comprehension. Effects of Living Books met the criteria of differential susceptibility. For carriers of the dopamine receptor D4 gene seven-repeat allele (about one-third of the delayed group), the Living Books program was an important addition to the common core curriculum in kindergarten (effect size d = 0.56), whereas the program did not affect the other children (d = –0.09). The same seven-repeat carriers benefited more from Living Letters than did the noncarriers, as reflected in effect sizes of 0.63 and 0.34, respectively, although such differences did not fulfill the statistical criteria for differential susceptibility. The implications of differential susceptibility for education and regarding the crucial question “what works for whom?” are discussed. [ABSTRACT FROM AUTHOR]

Highlights: [•] A RCT was carried out to test effects of alphabet book sharing on learning letters. [•] It was also tested how the visual processing of pictures and letters affected learning. [•] Especially pictures of human and anthropomorphic interfered with learning letters. [•] Only a small part of letters attracted children’s visual attention. [•] Being familiar with distinctive features of letters may be an important step in learning letters. [ABSTRACT FROM AUTHOR]

Abstract: Research findings: The 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 policy: Computer 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. [Copyright &y& Elsevier]
