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…

Dynamics of morphological processing in pre-school children with and without familial risk for dyslexia

2020

Difficulties in phonological processing and speech perception are associated with developmental dyslexia, but there is considerable diversity across people with developmental dyslexia (e.g., dyslexics with and without phonological difficulties). Phonological and morphological awareness are both known to play an important role in reading acquisition. Problems in morpho-phonological information processing could arguably be associated with developmental dyslexia, especially for Finnish, which is a rich morphologically language. We used MEG to study the connection between morpho-phonology in the Finnish language and familial risk for developmental dyslexia. We measured event-related fields (ERF…

Influencia de los métodos de enseñanza en el aprendizaje y desarrollo de la lectura

2019

Esta comunicación se encuentra disponible en la siguiente URL: http://www.infad.eu/RevistaINFAD/OJS/index.php/IJODAEP/article/view/1467/1275 Este número está dedicado a la "Psicología de la Educación y Saberes Originarios". En el aprendizaje de la lectura están implicadas habilidades como la conciencia fonológica, la conciencia alfabética o la velocidad de nombramiento. Los distintos métodos de enseñanza influyen de modo diferencial en su adquisición. Este estudio analiza 1) el efecto diferencial de los métodos analíticos y fonológico-sintéticos en la adquisición de estas habilidades básicas, 2) si las diferencias encontradas en función del método siguen el mismo patrón en los 4 primeros cu…

The role of achievement beliefs and behaviours in spontaneous reading acquisition

2006

Abstract This study examined the role of motivational or attitudinal factors, such as achievement beliefs and behaviours, in learning to read before receiving formal instruction. A total of 200 Finnish children were examined at ages 5 and 6½. Half of them ( n  = 107) had a familial risk for dyslexia. The results showed that those children who were verbally skilful at age 5 showed a higher level of task-focused behaviour at age 6½. This task-focused behaviour then contributed to spontaneous reading acquisition. The impact of previous verbal skills on spontaneous reading acquisition was mediated in part by achievement behaviour.

Assessing dyslexia in Finnish high-school students: a pilot study

2000

A pilot study concerning Finnish dyslexics at senior high school (lukio), for 16–19-year-olds, is reported. The phonological processing deficit was assumed to underlie dyslexia in these late teenage subjects. The regular nature of Finnish orthography was taken into consideration. Four tasks were introduced to a total of 32 students, of whom 15 were dyslexics and 17 were controls. The controls outperformed the dyslexics on three tasks: text recoding, pseudoword recoding and pseudoword spelling. On the text spelling task, both groups performed equally well. In the correlational analysis of all subjects, both recoding tasks showed high correlations with selfestimated school achievement in lang…
