Early prediction of reading : phonological awareness and related language and cognitive skills in children with a familial risk for dyslexia

2007

PsL Anne Puolakanaho selvitti väitöstutkimuksessaan, miten leikki-ikäisten 3 - 5-vuotiaiden lasten kielelliset ja kognitiiviset taidot ovat yhteydessä lukemisen virheettömyyteen ja sujuvuuteen kouluiässä. Puolakanaho tutki myös, missä määrin dysleksiaa eli sitkeää lukemisvaikeutta voidaan ennakoida lapsikohtaisesti, yksilöllisten riskitekijöiden perusteella jo huomattavasti ennen esikouluikää. Aiemmin lukutaitoa ennustavaa tutkimusta on tehty vanhemmilla lapsilla ja lähinnä kirjoitusjärjestelmältään epäsäännöllisessä englannin kielessä. - Myös kirjoitusjärjestelmältään säännönmukaisessa suomen kielessä leikki-ikäisten fonologis-kielelliset taidot kuten kyky tunnistaa puheesta tavuja ja äänt…

Predicting delayed letter name knowledge and its relation to grade 1 reading achievement in children with and without familial risk for dyslexia

2006

The authors examined the developmental trajectories of children's early letter knowledge in relation to measures spanning and encompassing their prior language-related and cognitive measures and environmental factors and their subsequent Grade 1 reading achievement. Letter knowledge was assessed longitudinally at ages 4.5, 5.0, 5.5, and 6.5 years; earlier language skills and environmental factors were assessed at ages 3.5 and 4.5 years; and reading achievement was assessed at the beginning and end of Grade 1. The analyses were conducted on a longitudinal data set involving children with and without familial risk for dyslexia. Emerging from the trajectory analysis of letter knowledge were 3 …

Unveiling the Mysteries of Dyslexia-Lessons Learned from the Prospective Jyväskylä Longitudinal Study of Dyslexia.

2021

This paper reviews the observations of the Jyväskylä Longitudinal Study of Dyslexia (JLD). The JLD is a prospective family risk study in which the development of children with familial risk for dyslexia (N = 108) due to parental dyslexia and controls without dyslexia risk (N = 92) were followed from birth to adulthood. The JLD revealed that the likelihood of at-risk children performing poorly in reading and spelling tasks was fourfold compared to the controls. Auditory insensitivity of newborns observed during the first week of life using brain event-related potentials (ERPs) was shown to be the first precursor of dyslexia. ERPs measured at six months of age related to phoneme length identi…

Literacy Skill Development of Children With Familial Risk for Dyslexia Through Grades 2, 3, and 8

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 familial risk for dyslexia (controls, n = 72). The Dys_FR group showed persistent deficiency, especially in reading speed, and, to a minor extent, in reading and spelling accuracy. The Dys_FR children, contrary to the other 2 groups, relied heavily on letter-by-letter decoding in Grades 2 and 3. In children not fulfilling the criteria for dyslexia in…

What information should I look for again? : Attentional difficulties distracts reading of task assignments

2019

This large-scale eye-movement study (N = 164) investigated how students read short task assignments to complete information search problems and how their cognitive resources are associated with this reading behavior. These cognitive resources include information searching subskills, prior knowledge, verbal memory, reading fluency, and attentional difficulties. In this study, the task assignments consisted of four sentences. The first and last sentences provided context, while the second or third sentence was the relevant or irrelevant sentence under investigation. The results of a linear mixed-model and latent change score analyses showed the ubiquitous influence of reading fluency on first…

Spoken-Word Segmentation and Dyslexia

2002

We used magnetoencephalography to elucidate the cortical activation associated with the segmentation of spoken words in nonreading-impaired and dyslexic adults. The subjects listened to binaurally presented sentences where the sentence-ending words were either semantically appropriate or inappropriate to the preceding sentence context. Half of the inappropriate final words shared two or three initial phonemes with the highly expected semantically appropriate words. Two temporally and functionally distinct response patterns were detected in the superior temporal lobe. The first response peaked at approximately 100 msec in the supratemporal plane and showed no sensitivity to the semantic appr…
