Developmental Underpinnings of the Association of Attention Deficit Hyperactivity Disorder and Its Subtypes to Neuropsychological and Academic Weaknesses
Caron and Rutter (1) and Pennington (2) recently published excellent conceptual and methodological reviews and analyses of comorbidity in child psychopathology, and a special issue of Developmental Neuropsychology (3) reviewed attention deficit hyperactivity disorder (ADHD)-learning disabilities (LD) comorbidity in particular. None of these reviews, however, focused on the association of dimensions of ADHD and cognitive development, which are included in this chapter. Moreover, relatively little empirical data exist from early development. It is very likely that language-related impairments and extreme temperament traits contribute to the emergence of developmental problems and/or the accum…
Supporting Acquisition of Spelling Skills in Different Orthographies Using an Empirically Validated Digital Learning Environment
This paper discusses how the association learning principle works for supporting acquisition of basic spelling and reading skills using digital game-based learning environment with the Finland-based GraphoLearn (GL) technology. This program has been designed and validated to work with early readers of different alphabetic writing systems using repetition and reinforcing connections between spoken and written units. Initially GL was developed and found effective in training children at risk of reading disorders in Finland. Today GL training has been shown to support learning decoding skills among children independent of whether they face difficulties resulting from educational, social, or bi…
Corpus Callosum Morphology in Attention Deficit-Hyperactivity Disorder: Morphometric Analysis of MRI
Although behavioral evidence provides support for the notion that attention deficit-hyperactivity disorder (ADHD) is related to central nervous system dysfunction, there is little direct evidence to reveal which neurometabolic systems or brain structures are involved. Recent magnetic resonance imaging (MRI) studies suggest that, compared to nondisabled controls, ADHD children may have a smaller right frontal region. Morphometric analysis of MRI scans was used in this exploratory study to determine whether correlated regional variation might exist in the corpus callosum of children with ADHD. While all MRI scans were judged to be clinically normal, morphometric analysis revealed that, compa…
