Our approach to the emerging global reality…
Considering the current local/global pace of change and recognizing that there are increasingly fewer secure jobs, businesses, and/or markets, we believe that the best way to prepare one and all for the future is to enhance and accelerate the way we think, learn, understand and express what we know and what we want to say so that we are effectively prepared for the future, regardless of its permutations.

Private speech use in arithmetical calculation: relationship with phonological memory skills in children with and without mathematical difficulties.
(Tue 28 of Apr., 2015)
Authors: Ostad SA Abstract The majority of recent studies conclude that children's private speech development (private speech internalisation) is important for mathematical development and subject to disabling. The main concern of the present study was whether or not the two phonological memory factors evaluated in the study (i.e. the results of children's digit span assessments, both forward and backward) relates to private speech internalisation and whether this relationship changes with children's age, or mathematical achievement levels, or both. We made comparisons between children with acknowledged mathematical difficulties (MD) and children without mathematical difficulties (MN), basing on private speech differences, phonological memory differences and differences in the rela...MedWorm Sponsor Message: Directory of the best January Sales in the UK.

Brain differences seen in children with dyslexia, dysgraphia
(Tue 28 of Apr., 2015)
Structural brain differences between children with dyslexia and dysgraphia and children who are typical language learners have been observed by researchers in a recent study. Researchers say the findings prove that using a single category of learning disability to qualify for special education services is not scientifically supported.

An assessment of gene-by-gene interactions as a tool to unfold missing heritability in dyslexia
(Mon 27 of Apr., 2015)
Abstract Even if substantial heritability has been reported and candidate genes have been identified extensively, all known marker associations explain only a small proportion of the phenotypic variance of developmental dyslexia (DD) and related quantitative phenotypes. Gene-by-gene interaction (also known as “epistasis”—G × G) triggers a non-additive effect of genes at different loci and should be taken into account in explaining part of the missing heritability of this complex trait. We assessed potential G × G interactions among five DD candidate genes, i.e., DYX1C1, DCDC2, KIAA0319, ROBO1, and GRIN2B, upon DD-related neuropsychological phenotypes in 493 nuclear families with DD, by implementing two complementary regression-based approaches: (1) a general linear mo...MedWorm Sponsor Message: Directory of the best January Sales in the UK.

Dyslexia and voxel-based morphometry: correlations between five behavioural measures of dyslexia and gray and white matter volumes.
(Thu 23 of Apr., 2015)
We presented an overview of uncorrected clusters of voxels (p < 0.05, cluster size k > 200) with reduced or increased GM volume. We found four significant correlations between factors of dyslexia representing various behavioural measures and the clusters found in the first analysis. In the whole sample, a factor related to performances in spelling correlated negatively with GM volume in the left posterior cerebellum. Within the group of dyslexics, a factor related to performances in Dutch-English rhyme words correlated positively with GM volume in the left and right caudate nucleus and negatively with increased total WM volume. Most of our findings were in accordance with previous reports. A relatively new finding was the involvement of the caudate nucleus. We confirmed the m...
Common childhood neurodevelopmental disorders are associated with increased risk of psychotic experiences in early adolescence
(Wed 22 of Apr., 2015)
ABSTRACT FROM: Khandaker G, Stochl J, Zammit S, et al. A population-based longitudinal study of childhood neurodevelopmental disorders, IQ and subsequent risk of psychotic experiences in adolescence. Psychol Med 2014;44:3229–38. What is already known on this topic The disturbance of normal brain development, dating from the prenatal or perinatal period, is a key tenet of the neurodevelopmental hypothesis of schizophrenia.1 Similarities exist between schizophrenia and certain neurodevelopmental disorders (NDDs) of childhood, such as autism and intellectual disability, which both increase the risk of psychotic outcomes.2–4 However, it is unknown whether there is any relationship between schizophrenia and many other NDDs, such as dyslexia, dyspraxia and dyscalculia, leaving it unc...MedWorm Sponsor Message: Directory of the best January Sales in the UK.
