Rock-solid self-confidence is in the genes

London, July 2 (ANI): If you always attributed a rock-solid self-confidence to upbringing and other environmental factors then better think again, for an unshakeable self belief is in the genes, according to a new study.

The psychiatrists behind the study say that the ability to perform under pressure is more than a state of mind, and that some people are just born with it.

They have also shown that children with a greater belief in their own abilities often perform better at school, even if they are actually less intelligent.

“Everyone has assumed self confidence is a matter of environment,” the Telegraph quoted Professor Robert Plomin, of the Institute of Psychiatry, King’s College, London, as saying.

He added: “Our research shows that it is certainly genetically influenced and that self confidence predicts achievement at school.”

Plomin and his colleague Corina Greven carried out the study, which showed that children’s self-perceptions of their abilities are clearly based on genes.

The researchers asked over 3,700 both identical and non-identical twin pairs, from the age of seven to ten, to rate their abilities in a number of core school subjects and assessed the relative contributions of genes and environment.

Studying twins is useful because identical twins have the same genes and the same environment whereas non-identical have different genes but the same environment.

Thus, on comparing the two, many “nature versus nurture” questions can be answered.

Contrary to the age-old belief, the researchers found that confidence is heavily influenced by genetics, at least as much as IQ is.

The genes would appear to influence school performance independent of IQ genes, with shared environment having only a negligible influence.

“We are not saying that genes are the only factor or that upbringing and environment cannot change things,” said Plomin.

He added: “But there is something genetic in self confidence which I would think of as a personality trait that would be stable throughout life.”

The study’s findings have been published in the journal Psychological Science. (ANI)

Genetic link between sleep disorders and depression in young kids found

Washington, Feb 02 (ANI): British scientists have for the first time found a genetic link between sleep disorders and depression in young children.

Researchers at Goldsmiths College in London say that genetics is the most important factor in explaining the link between sleep problems early in life and the later development of depression.

Their findings are consistent with the theory that early treatment of sleep problems may protect children from the development of depression.

Results also indicate that the stability of sleep problems across time is mainly caused by genetic factors (46 percent of the genetic influences on sleep at age 10 were the same as those that influenced a child at age of eight).

Lead-author of the study, Alice M. Gregory, senior lecturer in psychology at Goldsmiths College, London and co-author of the study, said the most surprising result concerned the reasons why there may be links between sleep problems and depression at different points in a young person’s life.

Data was collected from 300 twin pairs born in England and Wales between 1994 and 1996. Anxiety was examined at age seven using the parent-report Anxiety Related Behaviours Questionnaire (ARBQ), a 21-item scale reflecting commonly assessed anxiety-related behaviours in young children (including general distress, separation anxiety, shyness, inhibition and fears).

Two hundred forty-seven twin pairs scored highly on parent-reported anxiety at age seven; 53 control twin pairs also were selected to ensure full coverage of the full range of scores on test measures, said a Goldsmith release.

Parents reported on their eight-year-old children’s sleep problems using the abbreviated version of the Child Sleep Habits Questionnaire (CSHQ).

The study was published in the February issue of SLEEP. (ANI)
