Journal ArticleDOI
Orthographic Depth and Its Impact on Universal Predictors of Reading A Cross-Language Investigation
Johannes C. Ziegler,Daisy Bertrand,Dénes Tóth,Valéria Csépe,Alexandra Reis,Alexandra Reis,Luís Faísca,Nina L. Saine,Heikki Lyytinen,Anniek Vaessen,Leo Blomert +10 more
TL;DR: Results from a sample of 1,265 children in Grade 2 showed that phonological awareness was the main factor associated with reading performance in each language, however, its impact was modulated by the transparency of the orthography, being stronger in less transparent orthographies.
Journal ArticleDOI
Neural systems predicting long-term outcome in dyslexia
Fumiko Hoeft,Bruce D. McCandliss,Jessica M. Black,Alexander Gantman,N Zakerani,Charles Hulme,Heikki Lyytinen,Susan Whitfield-Gabrieli,Gary H. Glover,Allan L. Reiss,John D. E. Gabrieli +10 more
TL;DR: Right prefrontal brain mechanisms that may be critical for reading improvement in dyslexia and that may differ from typical reading development are identified and brain measures that predict future behavioral outcomes may be more accurate, in some cases, than available behavioral measures.
Journal ArticleDOI
Corpus Callosum Morphology in Attention Deficit-Hyperactivity Disorder: Morphometric Analysis of MRI
George W. Hynd,Margaret Semrud-Clikeman,Alison R. Lorys,Edward S. Novey,Deborah Eliopulos,Heikki Lyytinen +5 more
TL;DR: For instance, this paper found that ADHD children had a smaller corpus callosum, particularly in the region of the genu and splenium, and in the area just anterior to the splenium.
Journal ArticleDOI
Brain sensitivity to print emerges when children learn letter–speech sound correspondences
Silvia Brem,Silvia Bach,Silvia Bach,Karin Kucian,Tomi K. Guttorm,Ernst Martin,Heikki Lyytinen,Daniel Brandeis,Ulla Richardson +8 more
TL;DR: The occipito-temporal print sensitivity thus is established during the earliest phase of reading acquisition in childhood, suggesting that a crucial part of the later reading network first adopts a role in mapping print and sound.
Journal ArticleDOI
A candidate gene for developmental dyslexia encodes a nuclear tetratricopeptide repeat domain protein dynamically regulated in brain
Mikko Taipale,Nina Kaminen,Jaana Nopola-Hemmi,Tuomas Haltia,Birgitta Myllyluoma,Heikki Lyytinen,Kurt Müller,M Kaaranen,Perttu J. Lindsberg,Katariina Hannula-Jouppi,Juha Kere +10 more
TL;DR: It is concluded that DYX1C1 should be regarded as a candidate gene for developmental dyslexia and detailed study of its function may open a path to understanding a complex process of development and maturation of the human brain.
