The Twins Early Development Study (TEDS) is an ongoing longitudinal twin study headed by principal investigator psychologist Robert Plomin and based at King's College London. The main goal of TEDS is to use behavioural genetic methods to find out how nature (genes) and nurture (environments) can explain why people differ with respect to their cognitive abilities, learning abilities and behaviours. Over 15,000 pairs of twins originally signed up for the study and more than 13,000 pairs remain involved to the present day. This demonstrates the continued support of all twins and their families for more than a decade.

Famous quotes containing the words twins, early, development and/or study:
“What if there are not only two nostrils, two eyes, two lobes, and so forth, but two psyches as well, and they are separately equipped? They go through life like Siamese twins inside one person.... They can be just a little different, like identical twins, or they can be vastly different, like good and evil.”
—Norman Mailer (b. 1923)
“I looked at my daughters, and my boyhood picture, and appreciated the gift of parenthood, at that moment, more than any other gift I have ever been given. For what person, except one’s own children, would want so deeply and sincerely to have shared your childhood? Who else would think your insignificant and petty life so precious in the living, so rich in its expressiveness, that it would be worth partaking of what you were, to understand what you are?”
—Gerald Early (20th century)
“For the child whose impulsiveness is indulged, who retains his primitive-discharge mechanisms, is not only an ill-behaved child but a child whose intellectual development is slowed down. No matter how well he is endowed intellectually, if direct action and immediate gratification are the guiding principles of his behavior, there will be less incentive to develop the higher mental processes, to reason, to employ the imagination creatively. . . .”
—Selma H. Fraiberg (20th century)
“In making a speech one must study three points: first, the means of producing persuasion; second, the language; third the proper arrangement of the various parts of the speech.”
—Aristotle (384–323 B.C.)
