A meta-analysis of morphological interventions: effects on literacy achievement of children with literacy difficulties.
This study synthesizes 79 standardized mean-change differences between control and treatment groups from 17 independent studies, investigating the effect of morphological interventions on literacy outcomes for students with literacy difficulties. Average total sample size ranged from 15 to 261 from a wide range of grade levels. Overall, morphological instruction showed a significant improvement on literacy achievement ([Formula: see text] = 0.33). Specifically, its effect was significant on several literacy outcomes such as phonological awareness ([Formula: see text] = 0.49), morphological awareness ([Formula: see text] = 0.40), vocabulary ([Formula: see text] = 0.40), reading comprehension ([Formula: see text] = 0.24), and spelling ([Formula: see text] = 0.20). Morphological instruction w......

Another joint statement regarding learning disabilities, dyslexia, and vision-A rebuttal.
Authors: Lack D
Several medical organizations have published yet another joint statement trivializing vision therapy and vision disorders in the learning-disabled population. A review of the references in the joint statement as well as other references find that the joint statement is misleading because of inappropriate citations and selected references, as was the case with previous joint statements. The most current joint statement ignores the results of evidence-based research and makes recommendations regarding the treatment of convergence insufficiency that have no scientific validity. Ophthalmology should not allow professional rivalry to cloud its judgment regarding optometry's involvement in the diagnosis and treatment of learning-related vision problems.

Dyslexia-Associated Kiaa0319-Like Protein Interacts with Axon Guidance Receptor Nogo Receptor 1.
Authors: Poon MW, Tsang WH, Chan SO, Li HM, Ng HK, Waye MM
To identify the putative interacting partners for Kiaa0319-like protein. KIAA0319-like, located near the dyslexia susceptibility locus, DYX8 in chromosome 1p34.3, has been suggested as a positional candidate for developmental dyslexia due to its homology with another gene, KIAA0319 which has been strongly established as a candidate gene for developmental dyslexia. Previous research has shown that a single marker, rs7523017 (P = 0.042) has been associated with developmental dyslexia by a Canadian group. There is little functional information about this gene and protein. In this article, we put forward further evidence that support Kiaa0319-like is a candidate for this disorder. A yeast-2-hybrid screen and co-immunopreciptiation ......

Are preservice teachers prepared to teach struggling readers?
Authors: Washburn EK, Joshi RM, Binks Cantrell E
Reading disabilities such as dyslexia, a specific learning disability that affects an individual's ability to process written language, are estimated to affect 15-20% of the general population. Consequently, elementary school teachers encounter students who struggle with inaccurate or slow reading, poor spelling, poor writing, and other language processing difficulties. However, recent evidence may suggest that teacher preparation programs are not providing preservice teachers with information about basic language constructs and other components related to scientifically based reading instruction. As a consequence preservice teachers have not exhibited explicit knowledge of such concepts in previous studies. Few studies have sought to as......

The Relationship Between Brainstem Temporal Processing and Performance on Tests of Central Auditory Function in Children with Reading Disorders.
CONCLUSIONS: Results underscore the importance of central auditory assessment for children with dyslexia. Further, the BioMARK may be useful in identifying children with central auditory dysfunction who would not have been identified using behavioral methods of (C)APD assessment.

Polygenic Heterogeneity: A Complex Model of Genetic Inheritance in Psychiatric Disorders
A polygenic/threshold model of psychiatric disorder was first introduced more than 40 years ago by Gottesman and Shields (). They proposed, following on from the seminal work of Falconer (), that what is inherited is not so much a disorder as a liability to disorder contributed to by multiple genetic and environmental effects. What has emerged in recent studies is an even more complex pattern of polygenic heterogeneity whereby phenotypically different syndromes appear to result from overlapping liabilities () (). An article in the current issue of Biological Psychiatry by Pagnamenta et al. () provides another example of this phenomenon relating to autism and dyslexia. Furthermore, the article demonstrates another feature of polygenic inheritance. In addition to those individuals who defini......

Is season of birth related to developmental dyslexia?
Authors: Donfrancesco R, Iozzino R, Caruso B, Ferrante L, Mugnaini D, Talamo A, Miano S, Dimitri A, Masi G
Different moderators/mediators of risk are involved in developmental dyslexia (DD), but data are inconsistent. We explored the prevalence of season of birth and its association with gender and age of school entry in an Italian sample of dyslexic children compared to an Italian normal control group. The clinical sample included 498 children (345 boys, mean age 10.3 +/- 2.1 years) with DD, the control sample 1,276 children (658 boys, mean age 10.8 +/- 2.2 years) from four elementary schools from the same urban area, and with the same socio-economic status level. A prevalence of birth in autumn was found among children with DD compared to controls (34% versus 24%, p < 0.0001). Chi......

Multivariate predictive model for dyslexia diagnosis.
Authors: Le Jan G, Le Bouquin-Jeannès R, Costet N, Trolès N, Scalart P, Pichancourt D, Faucon G, Gombert JE
Dyslexia is a specific disorder of language development that mainly affects reading. Etiological researches have led to multiple hypotheses which induced various diagnosis methods and rehabilitation treatments so that many different tests are used by practitioners to identify dyslexia symptoms. Our purpose is to determine a subset of the most efficient ones by integrating them into a multivariate predictive model. A set of screening tasks that are the most commonly used and representative of the different cognitive aspects of dyslexia was proposed to 78 children from elementary school (mean age = 9 years +/- 7 months) exempt from identified reading difficulties and to 35 dy......

Music benefits the brain, research reveals
(NaturalNews) Northwestern University scientists have pulled together a review of research into what music -- specifically, learning to play music -- does to humans. The result shows music training does far more than allow us to entertain ourselves and others by playing an instrument or singing. Instead, it actually changes our brains.The paper, just published in Nature Reviews Neuroscience, is a compilation of research findings from scientists all over the world who used all kinds of research methods. The bottom line to all these studies: musical training has a profound impact on other skills including speech and language, memory and attention, and even the ability to convey emotions vocally. So what is it that musical training does? According to the Northwestern scientists, the findings ......
