The study investigated how well Swedish adolescents recognize the meaning of derived words in English and whether this knowledge is determined by learner proficiency, word frequency, or affix type. Participants were 88 school students in two proficiency groups: 39 advanced 12th graders and 49 intermediate 9th graders. Two tests of receptive…

Purpose: Although the existing literature has explored the link between cognitive functioning and speech recognition in noise, the specific role of fluid intelligence still needs to be studied. Given the established association between working memory capacity (WMC) and fluid intelligence and the predictive power of WMC for speech recognition in…

We investigated the stability and developmental interplay of word reading and spelling in samples of Swedish (N = 191) and U.S. children (N = 489) followed across four time points: end of kindergarten, grades 1, 2, and 4. Cross-lagged path models revealed that reading and spelling showed moderate to strong autoregressive effects, with reading…

Multilingual children living in areas with low socioeconomic status (SES) are at an increased risk of having speech, language and communication needs (SLCN). Many multilingual children with SLCN in Sweden have insufficient basic vocabulary knowledge in the majority language, preventing them from achieving the school's learning goals. However,…

Reading difficulties are linked to several disadvantages in the general population. Less is known about correlates of reading difficulties in individuals with intellectual and severe developmental disabilities (IDD). Vocabulary and word reading were assessed in 112 adolescents with IDD, recruited from Special needs comprehensive schools in Sweden…

We present quantitative results from the pilot-year of a large scale Swedish educational project in reading development called LegiLexi, inspired by research within the response to intervention and formative assessment traditions. The vision of the project is that every pupil should reach adequate reading skills at the end of grade 3 in primary…

Word reading skills and reading-related language and cognitive correlates were examined in Swedish 10-15-year-olds with autism spectrum disorders (ASD). The full group with ASD did not differ statistically from an age-matched comparison group in word reading, but a poor-readers subgroup was identified who displayed severe difficulties. Normal…

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…

The present study demonstrated that students with mild intellectual disabilities are capable of constructing meaning from written text by guided social interaction. Participants were 40 adolescents in special schools divided into two intervention conditions: reciprocal teaching (RT) and inference teaching (IT). In RT the students practiced four…

In this study, the relationship between latent constructs of phonological awareness (PA) and rapid automatized naming (RAN) was investigated and related to later measures of reading and spelling in children learning to read in different alphabetic writing systems (i.e., Norwegian/Swedish vs. English). 750 U.S./Australian children and 230…

The purpose of the present study was to examine the effects of three computerized interventions on the reading skills of children with reading disabilities in Grade 2. This longitudinal intervention study included five test sessions over 1 year. Two test points occur before the intervention, and three afterwards. The last follow-up was conducted 1…

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…

The Matthew effect is often used as a metaphor to describe a widening gap between good and poor readers over time. In this study we examined the development of individual differences in reading and cognitive functioning in children with reading difficulties and normal readers from Grades 1 to 3. Matthew effects were observed for individual…

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…

In a longitudinal intervention study, the effects of three intervention strategies on the reading skills of children with reading disabilities in Grade 2 were analyzed. The interventions consisted of computerized training programs: One bottom-up intervention aimed at improving word decoding skills and phonological abilities, the second…
