The concept of reading skill Basic readingskill – ability to pronouncewrittenwordsaccurately Literacy – readiness to comprehendfluentlywrittenlanguage; requires sufficientmasteryof the spokenlanguagemeant to belearned to read accurate and fluentbasicdecodingskill a lot of reading to acquirefunctionalreadingskill appropriatevocabularyknowledge, motivation and strategyto comprehend the writtenlanguage
Development of nonword reading accuracy during 1st Grade in different orthographies (Scottish data up to 2nd grade) Before school and then in equal time steps to the end of the 2.grade Results from COST A8, Seymour, et al. 2003
Readingacquisition and the consistency of the connectionsbetweenspoken and writtenlanguage If the readinginstruction is organizedas itshould… the timechildneeds for the acquisition of the basicreadingskill is the shorter the smaller the number of connectionsonehas to learn(Finnish, Swedish.. < 30 letter-sounds) the moreconsistentare the connections, ie. the fewercomplexities/alternativesneed to belearned and the moreoptimallybuiltphonicsinstructionis available for successfullyengaging the child in training the skill
..when biological factors compromise reading acquisition.. Jyväskylä Longitudinalstudy of Dyslexia (JLD; 1993-)The JLD researchgroupMikko Aro, Timo Ahonen, Kenneth Eklund, Tomi Guttorm, Jarmo Hämäläinen, Ritva Ketonen, Marja-Leena Laakso, Seija Leinonen, Matti Leiwo, Paavo Leppänen, Paula Lyytinen, Kurt Muller, Anna-Maija Poikkeus, Anne Puolakanaho, Ulla Richardson, Paula Salmi, Asko Tolvanen, Minna Torppa, Helena Viholainen
The goals of the JLD • to identify (from children at familial risk for dyslexia) • precursors of dyslexia • predictors of compromised acquisition • developmental paths leading to dyslexia • The last step: the development of preventive measures
DEFINING FAMILIAL RISK IN THE JYVÄSKYLÄ LONGITUDINAL STUDY OF DYSLEXIA (JLD) • SELECTION CRITERIA FOR THE AT-RISK FAMILIES: parents • At least one parent with diagnosed dyslexia from multiple criteria • Reported dyslexia among at least one of the first degree relatives • IQ at least 85 (Raven matrices) • No reported language problems in childhood or later • No neurological or psychiatric symptoms • No hearing problems For detals, see Leinonen et al. Reading and Writing, 2001

A learning environment for L1 and L2 spoken and written languages: Graphogame Introduces reading skill of any wanted language Teaches the phonetic basis of language with the help of written language • Tunes the speech perception for the use of a wanted language • Helps in training correct pronunciation of the sounds of a language • Introduces spoken words (vocabulary) via written language
