Direct linkBorleffs, Elisabeth; Maassen, Ben A. M.; Lyytinen, Heikki; Zwarts, Frans – Reading and Writing: An Interdisciplinary Journal, 2017
This narrative review discusses quantitative indices measuring differences between alphabetic languages that are related to the process of word recognition. The specific orthography that a child is acquiring has been identified as a central element influencing reading acquisition and dyslexia. However, the development of reliable metrics to…

Rimkute, Laura; Torppa, Minna; Eklund, Kenneth; Nurmi, Jari-Erik; Lyytinen, Heikki – Reading and Writing: An Interdisciplinary Journal, 2014
The present study examined the role that adolescents' dyslexia plays in their educational expectations, as well as their parents' expectations concerning their offspring's future education. To investigate this, 170 adolescents were asked to report their educational expectations on two occasions while they were still attending…

Hautala, Jarkko; Aro, Mikko; Eklund, Kenneth; Lerkkanen, Marja-Kristiina; Lyytinen, Heikki – Reading and Writing: An Interdisciplinary Journal, 2013
The role of letters and syllables in typical and dysfluent second grade reading in Finnish, a transparent orthography, was assessed by lexical decision and naming tasks. Typical readers did not show reliable word length effects in lexical decision, suggesting establishment of parallel letter processing. However, there were small effects of word…

Pennala, Riitta; Eklund, Kenneth; Hamalainen, Jarmo; Martin, Maisa; Richardson, Ulla; Leppanen, Paavo H. T.; Lyytinen, Heikki – Journal of Speech, Language, and Hearing Research, 2013
Purpose: The authors investigated the importance of phonemic length discrimination ability on reading and spelling skills among children with reading disabilities and familial risk for dyslexia and among children with typical reading skills, as well as the role of prereading skills in reading and spelling development in children with reading…

Lyytinen, Heikki – International Journal for Research in Learning Disabilities, 2014
A fundamental skill for growth and improvement in modern society is the ability to read--a skill still denied to many millions of children across the globe. A number of factors share the responsibility for this dilemma. In developing countries, most potential readers live under conditions where instruction is non-optimal or even unavailable…

Eklund, Kenneth; Torppa, Minna; Aro, Mikko; Leppänen, Paavo H. T.; Lyytinen, Heikki – Journal of Educational Psychology, 2015
This study followed the development of reading speed, reading accuracy, and spelling in transparent Finnish orthography in children through Grades 2, 3, and 8. We compared 2 groups of children with familial risk for dyslexia--1 group with dyslexia (Dys _FR, n = 35) and 1 group without (NoDys_FR, n = 66) in Grade 2--with a group of children without…

Eklund, Kenneth Mikael; Torppa, Minna; Lyytinen, Heikki – Dyslexia, 2013
This longitudinal study examined early cognitive risk and protective factors for Grade 2 reading disability (RD). We first examined the reading outcome of 198 children in four developmental cognitive subgroups that were identified in our previous analysis: dysfluent trajectory, declining trajectory, unexpected trajectory and typical trajectory. We…

Background: The relationship between phoneme awareness, rapid automatized naming (RAN), verbal short-term/working memory (ST/WM) and diagnostic category is investigated in control and dyslexic children, and the extent to which this depends on orthographic complexity. Methods: General cognitive, phonological and literacy skills were tested in 1,138…

Torppa, Minna; Eklund, Kenneth; van Bergen, Elsje; Lyytinen, Heikki – Dyslexia, 2011
This family-risk (FR) study examined whether the literacy skills of parents with dyslexia are predictive of the literacy skills of their offspring. We report data from 31 child-parent dyads where both had dyslexia (FR-D) and 68 dyads where the child did not have dyslexia (FR-ND). Findings supported the differences in liability of FR children with…

Purpose: To examine the ability to discriminate phonemic length and the association of this ability with reading accuracy, reading speed, and spelling accuracy in Finnish children throughout Grades 1-3. Method: Reading-disabled (RDFR, n = 35) and typically reading children (TRFR, n = 69) with family risk for dyslexia and typically reading control…

This longitudinal study examined the predictive associations between cumulative multidomain risk factors and cognitive (IQ), academic (reading fluency), and social adaptive outcomes at 8 to 9 years among 190 children with or without familial risk for dyslexia. Other risk factors included parental and neurocognitive risks assessed when the children…

Torppa, Minna; Georgiou, George; Salmi, Paula; Eklund, Kenneth; Lyytinen, Heikki – Scientific Studies of Reading, 2012
We examined the double-deficit hypothesis in Finnish. One hundred five Finnish children with high familial risk for dyslexia and 90 children with low family risk were followed from the age of 3 1/2 years until Grade 3. Children's phonological awareness, rapid naming speed, text reading, and spelling were assessed. A deficit in rapid automatized…

Torppa, Minna; Lyytinen, Paula; Erskine, Jane; Eklund, Kenneth; Lyytinen, Heikki – Journal of Learning Disabilities, 2010
Discriminative language markers and predictive links between early language and literacy skills were investigated retrospectively in the Jyvaskyla Longitudinal Study of Dyslexia in which children at familial risk for dyslexia have been followed from birth. Three groups were formed on the basis of 198 children's reading and spelling status. One…

Natale, Katja; Aunola, Kaisa; Nurmi, Jari-Erik; Poikkeus, Anna-Maija; Lyytinen, Paula; Lyytinen, Heikki – Journal of Learning Disabilities, 2008
The present study analyzed data from the Jyvaskyla Longitudinal Study of Dyslexia to investigate the factors to which mothers of children with and without familial risk for dyslexia attribute the causes of their first-grade children's reading achievement. Mothers' causal attributions were assessed three times during their children's first school…

Background: Analyses from the Jyvaskyla Longitudinal Study of Dyslexia project show that the key childhood predictors (phonological awareness, short-term memory, rapid naming, expressive vocabulary, pseudoword repetition, and letter naming) of dyslexia differentiate the group with reading disability (n = 46) and the group without reading problems…
