چکیده

Sixteen controls (age 6-13) and 20 native Italian children with developmental dyslexia (age 7-15) received a test of callosal transfer of tactile information. Among the dyslexic children, 7 had a diagnosis of L-type, 7 of P-type and 6 of M-type dyslexia according to Bakker's classification. Both control children and children with dyslexia made a significantly larger number of errors in the crossed localization condition (implying callosal transfer of tactile information) vs. the uncrossed condition. In the same condition, children with dyslexia made a significantly larger number of errors than controls. In the crossed localization condition L-types and M-types made a significantly larger number of errors than P-types and controls, while there was no significant difference in performance between P-types and controls. These findings are discussed in terms of defective callosal transfer or deficient somatosensory representation in children with L- and M-dyslexia.

Developmental dyslexia is traditionally defined as a discrepancy between reading ability and intelligence in children receiving adequate reading tuition. The possible existence of dyslexic subtypes has intrigued the researchers and practitioners for nearly a century. The aim of this research was to study the classification of subtypes of developmental dyslexia in Persian speakers. This resear...

Cognitive profiling and preliminary subtyping in Chinese developmental dyslexia.

The present study examined the cognitive profile and subtypes of developmental dyslexia in a nonalphabetic script, Chinese. One hundred and forty-seven Chinese primary school children with developmental dyslexia were tested on a number of literacy and cognitive tasks. The results showed that rapid naming deficit and orthographic deficit were the two most dominant types of cognitive deficits in ...

Computational Bases of Two Types of Developmental Dyslexia

The bases of developmental dyslexia were explored using connectionist models. The behavioral literature suggests that there are two dyslexic subtypes: ÒphonologicalÓ dyslexia involves impairments in phonological knowledge whereas in Òsurface Ó dyslexia phonological knowledge is apparently intact and the deficit may instead reflect a more general developmental delay. We examined possible computa...

Visual and Auditory Processing Impairments in Subtypes of Developmental Dyslexia: A Discussion

There has been a large body of research exploring sensory processing deficits in dyslexia, in both the visual and the auditory domains. Recently, there has also been evidence to suggest that dyslexia may be a heterogeneous disorder, with different patterns of dyslexia being identifiable. In this paper, we examine the relationship between these two bodies of research. First, we briefly review th...

Hemispheric dissociation and dyslexia in a computational model of reading.

There are several causal explanations for dyslexia, drawing on distinctions between dyslexics and control groups at genetic, biological, or cognitive levels of description. However, few theories explicitly bridge these different levels of description. In this paper, we review a long-standing theory that some dyslexics' reading impairments are due to impairments in hemispheric transfer. We test ...
