We examined the prevalence of comorbidity of dysfluent reading and math skills longitudinally in a representative sample (N = 1,928) and the stability of comorbid and single difficulties from first to fourth grades. The findings indicated that half the children who showed very low performance in one skill also evidenced low or very low performance…

This longitudinal study from Grades 1 to 4 investigated (a) the extent to which children select peers based on similarity in reading skills and (b) the extent to which children are influenced by the level of their peers' reading skills. The sample consisted of 1003 Finnish children in Grades 1-4, for whom reading fluency and comprehension were…

A latent profile analysis approach was used to examine the developmental profiles of task-avoidant behaviour and reading skills in Grades 1 and 2, as well as their antecedents in kindergarten. The participants in this study were 448 children. Four different developmental profiles of task-avoidant behaviour and reading skills were identified. Our…

We examined the cross-lagged relations between children's task-avoidant behavior and their performance in reading and spelling in Chinese. Eighty Grade 2 and 103 Grade 4 Mandarin-speaking Taiwanese children were assessed on measures of nonverbal IQ, task value, reading accuracy, fluency, and spelling. A year later, the children were reassessed on…

We examined the double deficit hypothesis (Wolf & Bowers, 1999) and literacy development in a longitudinal dataset of 1,006 Finnish children who were nonreaders at school entry. A single phonological awareness (PA) deficit was a predictor of pseudoword spelling accuracy and reading fluency, and a single rapid automatized naming (RAN) deficit…

This study examined the role of reading disability (RD) risk and environmental protective factors in reading fluency in grade 4. The sample consisted of 538 Finnish-speaking students. Kindergarten measures included the students' risk for RD based on poor achievement in phonological awareness and letter knowledge as well as information on the three…

The purpose of this study was twofold: (a) to examine the effect of task-focused behaviour on reading fluency, spelling and comprehension; and (b) to examine the role of the different literacy skills in subsequent task-focused behaviour. Two hundred and seven Finnish-speaking children were followed from preschool until their fourth year at school…

We examined the importance of children's classroom activity, defined as task-focused versus task-avoidance behavior, on different literacy outcomes in an orthographically consistent language. Greek children (n=95) were tested in kindergarten, grade 1, and grade 2 on measures of general cognitive ability, phonological awareness, RAN, and short-term…
