This paper describes a randomised control trial (RCT) of a small group intervention targeting articulatory consciousness in first graders with a reading delay (control condition: n = 57, intervention condition: n = 64). The programme in the intervention condition consisted of basic decoding and spelling tasks using articulatory cards to symbolise…

Social functioning and reading proficiency are critical for success in school and society. Therefore, identifying children with such problems is important. This study had 2 parts: first, a random sample of 234 elementary schools was surveyed about which instruments they use to assess reading proficiency and social functioning. Second, a systematic…

Morphemes, the smallest meaning-bearing units of language, recur in many words. Therefore, morphological knowledge can facilitate the comprehension of novel words. This study tested the effectiveness of a morphological training program on children's learning and retention of exposed words and morphologically related unexposed words compared with…

Research consistently documents that girls outperform boys in literacy achievement, yet, when considering the starting point--early literacy--we do not have consensus on the origin, meaningful nature, or persistence of such differences. In this two-part study analyzing 5,816 Norwegian students (48.1% girls, average age of 6.1 years), we first…

Background: There is increasing recognition of the contribution of morphological skills to the development of reading fluency. However, theoretical models and recent research raise questions about how different language skills influence reading development. Methods: The present study was designed to follow the reading development of a large sample…

This longitudinal study explores the association of motor competence and physical fitness with reading skills in children aged 9 and 12 years. Sixty-seven children aged 9 years completed an assessment of motor competence (measured using the Movement Assessment battery for Children), physical fitness (assessed using the Test of Physical Fitness),…

Rhythm plays an organisational role in the prosody and phonology of language, and children with literacy difficulties have been found to demonstrate poor rhythmic perception. This study explored whether students' performance on a simple rhythm task at school entry could serve as a predictor of whether they would face difficulties in word reading…

In this study of third grade school children, we investigated the association between writing process measures recorded with key stroke logging and the final written product. Moreover, we examined the cognitive predictors of writing process and product measures. Analyses of key strokes showed that while most children spontaneously made local…

The purpose of this study was to explore the hypothesis that teaching students knowledge of word forms and meanings supports the development of decoding and linguistic comprehension, which are fundamental components of reading comprehension. We examined this hypothesis by investigating the effects of a comprehensive word knowledge intervention on…

Modern behavior-genetic studies of twins in the United States, Australia, Scandinavia, and the United Kingdom show that genes account for most of the variance in children's reading ability by the end of the 1st year of formal reading instruction. Strong genetic influence continues across the grades, though the relevant genes vary for reading words…

Genetic and environmental relations between vocabulary and reading skills were explored longitudinally from preschool through Grades 2 and 4. At preschool there were strong shared-environment and weak genetic influences on both vocabulary and print knowledge but substantial differences in their source. Separation of etiology for vocabulary and…

Twin children from Australia, Scandinavia, and the United States were assessed for inattention, hyperactivity-impulsivity, and reading across the first 3 school years. Univariate behavior-genetic analyses indicated substantial heritability for all three variables in all years. Longitudinal analyses showed one genetic source operating across the…

It has been hypothesized that students with low self-efficacy will struggle with complex reading tasks in assessment situations. In this study we examined whether perceived reading self-efficacy and reading task value uniquely predicted reading comprehension scores in two different item formats in a sample of fifth-grade students. Results showed…

The genetic factor structure of a range of learning measures was explored in twin children, recruited in preschool and followed to Grade 2 ("N"?=?2,084). Measures of orthographic learning and word reading were included in the analyses to determine how these patterned with the learning processes. An exploratory factor analysis of the…

As part of a larger follow-up study, 75 students were diagnosed with dyslexia at 10 years of age. At the end of secondary school, grades for the whole cohort of 16-year olds were examined. At age 23 the whole study group responded to a questionnaire and the subgroup with dyslexia who responded to this questionnaire were invited to come for testing…
