Absolutely! It is very common for a child to have a higher IQ than her parents. Much of our brain development is education, diet, exposure to the world (travel, documentaries, friends, where you live). Our IQ's are not stagnate.
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.
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.
A University of Edinburgh study shows first-born children have higher IQs and better thinking skills than their siblings. The study says that shows first-born kids get more mental stimulation than their brothers and sisters.
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.
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.
Intelligence is also strongly influenced by the environment. During a child's development, factors that contribute to intelligence include their home environment and parenting, education and availability of learning resources, and healthcare and nutrition.
Although this is a robust and statistically significant finding the IQ difference is small. It means that in six out of ten cases the older sibling will have a higher IQ than the next youngest sibling.
First-born children's thinking skills outperform their siblings because they receive more mental stimulation from their parents in their early years, research suggests. First borns score higher than their siblings in IQ tests as early as age one, the study has found.
85 to 114: Average intelligence. 115 to 129: Above average or bright. 130 to 144: Moderately gifted. 145 to 159: Highly gifted.
An individual's IQ does not change with age. In other words: if you did an IQ test now and then another one in 10 years' time, your IQ score will probably be very similar. This is because IQ is always measured relative to other people your age.
Most people feel as though they look more like their biological mom or biological dad. They may even think they act more like one than the other. And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
The University of Edinburgh study reported that the oldest child tends to have a higher IQ and thinking skills than their younger siblings. This is due to higher mental stimulation the first-born receives, CBS affiliate KUTV reports.
A gifted child's IQ will fall within these ranges: Mildly gifted: 115 to 130. Moderately gifted: 130 to 145. Highly gifted: 145 to 160.
Genetically, intelligence and IQ is polygenic meaning that many genes are involved in determining intelligence. As such, the correlation between parents and their children and among siblings can vary within a pretty decent range. A study from 1979 found that the correlation between sibling IQs was 0.49.
Surpassing the IQs of well-known geniuses Bill Gates, Albert Einstein, and Isaac Newton, three black kids, Ramarni Wilfred, Anala Beevers and Alannah George, currently have the highest IQs in the world. Mensa is a non-profit high IQ society.
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].
The analysis found -- as a previous large-scale study did -- that first-borns enjoy a one-IQ-point advantage over later-borns, Damian said. The difference is statistically significant but meaningless, she said.
The first born may experience certain emotions differently than the middle and youngest child or visa versa. According to Adler, the first born is more susceptible to depression because of high expectations of parents and suddenly losing the attention due to another sibling being born.
Younger siblings generally have a lower IQ than their older brothers and sisters, according to three large national surveys from the US, UK, and Germany.
First-born kids tend to be leaders, like CEOS and founders, and are more likely to achieve traditional success. Middle-born children often embody a mix of the traits of older and younger siblings, and they're very relationship-focused.
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.
It is important to know that students who display poor working memory behavior will not necessarily have low IQ scores. Many of them can have average IQ scores.
Thus, on average, a bigger brain is associated with somewhat higher intelligence. Whether a big brain causes high intelligence or, more likely, whether both are caused by other factors remains unknown.
