Environmental component may be substantial After evaluating twin pairs in which at least one child has autism or autism spectrum disorder (ASD), researchers suggest that the shared environment may play a more substantial role in development of the condition than shared genes do, according to a report published Online First today by Archives of General Psychiatry, one of the JAMA/Archives journals. Current estimates suggest that 40 of every 10,000 children have autism, and prevalence rates for...

Living through weddings or divorces, job losses and children's triumphs, we sometimes feel better and sometimes feel worse. But, psychologists observe, we tend to drift back to a "set point""”a stable resting point, or baseline, in the mind's level of contentment or unease. Research has shown that the set points for depression and anxiety are particularly stable over time. Why? "The overwhelming view within psychiatry and psychology is that is due to genetic factors," says Virginia...

Children with ADHD can sometimes have more difficulties on math and reading tests compared to their peers. A new study published in Psychological Science, a journal of the Association for Psychological Science, used identical and fraternal twins to look at the genetic and environmental influences underlying ADHD behaviors, reading, and math skills in children in an attempt to better understand the relationship among them. Sara Hart, of the Florida State University, and her colleagues used...

Intelligence isn't the only thing that predicts how much education people get; family, culture, and other factors are important, too. A new study published in Psychological Science, a journal of the Association for Psychological Science, compares identical and fraternal twins in Minnesota and Sweden to explore how genetic and environmental factors involved in educational differ in countries with different educational systems. Family background can get an education even for people of low...

Finding supports modularity of the mind theory Recognizing faces is an important social skill, but not all of us are equally good at it. Some people are unable to recognize even their closest friends (a condition called prosopagnosia), while others have a near-photographic memory for large numbers of faces. Now a twin study by collaborators at MIT and in Beijing shows that face recognition is heritable, and that it is inherited separately from general intelligence or IQ. This finding plays...

While genetics play a key role in children's initial reading skills, a new study of twins is the first to demonstrate that environment plays an important role in reading growth over time. The results give further evidence that children can make  gains in reading during their early school years, above and beyond the important genetic factors that influence differences in reading, said Stephen Petrill, lead author of the study and professor of human development and family science at Ohio...

CHICAGO, Jan. 5 /PRNewswire/ -- A new study in the January issue of the Journal of Vascular Surgery(®), published by the Society for Vascular Surgery®, reveals robust epidemiological evidence that hereditary factors contribute to aneurysm formation in twins. Researchers in Sweden reviewed the data of 172,890 twins born in that country since 1886 and found 265 twins who had developed abdominal aortic aneurysms (AAAs). These individuals ranged from 48 to...

LONDON, November 12 /PRNewswire-FirstCall/ -- - A Love of Pop and Classical Music is Partly in our Genes If you've ever wondered why a close group of friends might like completely different types of music, blame their genes. A study by Nokia (NYSE: NOK) into the musical tastes of nearly 4,000 twins reveals genetic influences on the music people like varies with genre. While, on the whole, musical taste is determined just as much by nature as it is by specific individual...

A study contradicts research published earlier that concluded anesthesia in those younger than age 4 is linked to learning problems, a U.S. researcher says. Dr. Robert Althoff of the University of Vermont and colleagues Meike Bartels and Dorret Boomsma from VU University in the Netherlands controlled for genetic association by using a sample of 1,143 identical Dutch twin pairs, or 2,286 children total. The twins' cognitive outcomes were measured using a standardized national exam. While...

A recent study of more than 2,000 identical twins found that medical problems early in life, rather than the neurotoxic effects of anesthesia, are likely linked to an individual's risk for developing learning disabilities. The study's findings, reported in the journal Twin Research and Human Genetics, contradict research published earlier this year, which concluded that receiving anesthesia younger than age four is associated with subsequent learning problems.Robert Althoff, M.D., Ph.D.,...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
