Major Findings and Contributions
Oliver & Plomin (2007) provide an overview of TEDS findings. TEDS has made major contributions to the Genetics and Education literature, such as the formulation of the Generalist Genes Hypothesis of learning abilities and disabilities, and important contributions to the literature on the heritability of IQ and school achievement. Novel findings from TEDS also include the discovery that social and non-social behaviours exhibited by children with autistic spectrum disorder (ASD) are largely influenced by different genes. With respect to molecular genetics, TEDS has pioneered a novel strategy called SNP Microarrays and Pooling (SNP-MaP), which is a cost-effective and powerful way of genotyping DNA as it allows researchers to use one microarray instead of hundreds to genotype a group’s pooled DNA. It is hoped that it will eventually be possible to use the insights obtained from studies such as TEDS to help prevent or alleviate common learning disabilities such as dyslexia.

Famous quotes containing the words major and/or findings:
“A major misunderstanding of child rearing has been the idea that meeting a child’s needs is an end in itself, for the purpose of the child’s mental health. Mothers have not understood that this is but one step in social development, the goal of which is to help a child begin to consider others. As a result, they often have not considered their children but have instead allowed their children’s reality to take precedence, out of a fear of damaging them emotionally.”
—Elaine Heffner (20th century)
“Not many appreciate the ultimate power and potential usefulness of basic knowledge accumulated by obscure, unseen investigators who, in a lifetime of intensive study, may never see any practical use for their findings but who go on seeking answers to the unknown without thought of financial or practical gain.”
—Eugenie Clark (b. 1922)
