Research suggests that more cases of dyslexia are diagnosed in populations that speak languages with highly opaque writing systems, such as the United States, the United Kingdom, or France, and fewer cases of dyslexia are diagnosed in populations that speak language with transparent writing systems, such as Italy, Spain, or Mexico. This disparity can be explained by the differences in how dysle...

This study focused on English as L2 in a group of Norwegian dyslexic 12 year olds, compared to an age and gender matched control group. Norwegian school children learn English from the first grades on. The subjects were assessed with a test battery of verbal and written tasks. First, they were given a comprehension task; second, a model sentence task; third, two pragmatic tasks, and fourth, thr...

Detecting dyslexia in immigrant children can be jeopardized because of assessment bias, as a consequence of a limited word lexicon or differences in language development of these children. This is in contrast with the view of the universal neurocognitive basis for dyslexia. In this research, differences in screening children at risk for dyslexia with the Dyslexia Screening Test (DST) were studi...

This paper presents the first reading data in Croatian collected with an eye-tracking device. The eye-tracking method allows for research into two crucial levels underlying reading: the visual and the cognitive. The aim of this paper is to show the differences in eye movements in children with dyslexia using the principles of cognitive-control view. Despite the well-known definitions and vast l...

Limited research has been conducted on the structure of the pars triangularis (PT) in dyslexia despite functional neuroimaging research finding it may play a role in phonological processing. Furthermore, research to date has not examined PT size in ADHD even though the right inferior frontal region has been implicated in the disorder. Hence, one of the purposes of this study was to examine the ...

Abstract: This study examined the Dai, Wa, Jino ethnic minority Chinese developmental dyslexia children’s processing defects of linguistics cognitive level and non-linguistic cognitive level by two experiments. Experiment 1 used the pronunciation repeat, orthography true and false judgment and sentence comprehension tasks to investigate the linguistic cognitive processing defects of different e...

The cerebellar deficit hypothesis for developmental dyslexia claims that cerebellar dysfunction causes the failures in the acquisition of visuomotor skills and automatic reading and writing skills. In people with dyslexia in the alphabetic languages, the abnormal activation and structure of the right or bilateral cerebellar lobes have been identified. Using a typical implicit motor learning tas...

In this study we focused on the spelling of high-functioning students with dyslexia. We made a detailed classification of the errors in a word and sentence dictation task made by 100 students with dyslexia and 100 matched control students. All participants were in the first year of their bachelor's studies and had Dutch as mother tongue. Three main error categories were distinguished: phonologi...

Dyslexia and attentional problems are often comorbid. This raises the question whether reading deficits might etiologically follow from attentional difficulties, a hypothesis that has been proposed in regard to visuo-spatial attention deficits. This visuo-spatial attention deficit hypothesis would predict that attention deficits should be specific to dyslexia. However, it is here estimated that...

Developmental dyslexia is characterized by an unexpected difficulty in reading experienced by children and adults who otherwise possess the intelligence and motivation considered necessary for accurate and fluent reading. It represents one of the most common problems affecting children and adults; in the United States, the prevalence of dyslexia is estimated to range from five to 17 percent of ...
