What brings down IQ?

Using laptops, phones and other media devices at the same time could shrink important structures in the brain, a study indicates. Neuroscientists have found that people who use multiple devices simultaneously have lower gray-matter density in an area of the brain associated with cognitive and emotional control.

Can low IQ parents have a high IQ child?

But genetics can explain the wide range of possible IQs too because so many different genes are involved in developing and running a brain. It is possible, for example, to inherit all the higher IQ genes from each parent and leave the lower IQ ones behind. Now the child will be brighter than the parent.

How much of IQ is genetic?

Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%, with some recent studies showing heritability for IQ as high as 80%. IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults.

Does your childhood affect your IQ?

Study finds brain structure and IQ can change during adolescence. A new study confirms what parents have long suspected: Adolescence can do a number on kids' brains. Researchers have found that IQ can rise or fall during the teen years and that the brain's structure reflects this uptick or decline.

Does trauma affect IQ?

There were significant differences in the impact of childhood trauma on IQ across the 3 groups. Exposure in HCS was associated with a nearly 5-point reduction in IQ (−4.85; 95% confidence interval [CI]: −7.98 to −1.73, P = . 002), a lesser reduction in siblings (−2.58; 95% CI: −4.69 to −0.46, P = .
