Also, is intelligence more of a genetic or environmental trait?” If a person with a high IQ marries someone with a lower IQ, their kids could have most any IQ. The same is true for two high IQ parents (although their kids will tend to have higher IQs).
Intelligence has a very high heredity component, so often times the parents of smart people are smart. But this is not a necessity. Rare gene combinations can often lead to interesting results and two very smart people might have a really average child, we call this statistical regression to the mean.
A child was born smart or not, and little could be done to change that. More recent research has upended that notion, and shown that encouraging parents to adopt a so-called growth mindset leads to better educational outcomes for their children.
Researchers examined the question of whether the more intelligent infant becomes the more intelligent and more highly achieving adult. "Yes" is the answer Fagan and his research team found.
IQ of a Child
The characteristics of who a parent is and the way he or she decides to raise his or her children may play a role in a child's intellectual development. The amount of education a parent has had, the home environment a parent establishes, and the parent's culture may all have an effect on a child's IQ.
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.
Parental education is one of the best predictors of child school achievement.
They found a one-third higher risk of autism in children whose fathers' IQ scores are 111 or higher than in those whose fathers' scores cluster around 100.
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors.
One of the earliest signs of an intelligent baby is a high level of alertness. Such babies are also very aware of their environments and loved ones, quickly recognising and bonding with family members.
SALT LAKE CITY (KUTV) — Studies have shown that first-born children are smarter than their siblings, and now we're learning that second-born children are more likely to cause trouble. A University of Edinburgh study shows first-born children have higher IQs and better thinking skills than their siblings.
Giftedness can create problems and conflicts; being a gifted child can also mean difficulty socializing with age peers, thinking styles that don't always mesh well with the demands from the environment, even children who see themselves as little adults, challenging teachers and parents.
Researchers find that brain development peaks years later for children with the highest IQs. Smart children have a different rhythm in their heads — a seesaw pattern of growth that lags years behind other young people — say government scientists who mapped the brains of hundreds of children.
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.
Joseph Hotz and Juan Pantano and they found that the oldest kids had higher IQs, performed better at school in terms of grades, and are believed to be more accomplished.
&ween Parents and Children
The average IQ difference between a parent and his (or her) child is the same as the difference between siblings-that is, about 12 IQ points. The difference between a child and the average of both of his parents' IQ's is about 10 points.
IQ peaks at around 20-years-old and later effort will not improve it much beyond this point, research finds. The complexity of people's jobs, higher education, socialising and reading all probably have little effect on peak cognitive ability.
Ability to learn new topics quickly. Ability to process new and complex information rapidly. Desire to explore specific topics in great depth. Insatiable curiosity, often demonstrated by many questions.
Crystallized intelligence "averages 98 at ages 20–24, rises to 101 by ages 35–44, before declining to 100 (ages 45–54), then 98 (55–64), then 96 (65–69), then 93 (70–74), and 88 (75+)," says Kaufman. Fluid intelligence drops much more quickly.
Furthermore, high levels of testosterone in the womb may play a role in the development of both technical and autistic minds. 12.5 percent of fathers of children with autism were engineers, compared with only 5 percent of fathers of children without autism.
Those with Asperger's syndrome, in contrast, must by definition have suffered no cognitive delay during their first 3 years of life. This means that they will usually have at least a “normal” IQ. In some cases, their IQ may be very high, even in the genius range. There are, however, different kinds of smarts.
Does The Father Or Mother Carry The Autism Gene? Autism was always thought to have a maternal inheritance component, however, research suggests that the rarer variants associated with the disorder are usually inherited from the father.
According to this new study, children with the highest IQs start out with a thinner cortex, which undergoes rapid growth, peaking at around age 12, instead of age 8 or 9 for children who got average scores on IQ tests.
Empirical evidence suggests that especially parental education, parental income, and maternal IQ are important predictors of intelligence. Parental education together with maternal IQ and the child's sex were found to account for 24% of the variance in IQ at age 5 [6].
