The Difference Between Being Smart, Educated, and Intelligent
could make it difficult to appropriately manage finances, function independently without assistance, and understand the consequences of – or react appropriately to – mistakes.”
This is a key finding which speaks directly to the (psychological) definition of intelligence which is addressed later in this article.
ULTRA SOUNDS
Studies have shown that the frequent exposure of the human fetus to ultrasound waves is associated with a decrease in newborn body weight, an increase in the frequency of left-handedness, and delayed speech.
Because ultrasound energy is a high-frequency mechanical vibration, researchers hypothesized that it might influence the migration of neurons in a developing fetus. Neurons in mammals multiply early in fetal development and then migrate to their final destinations. Any interference or disruption in the process could result in abnormal brain function.
Commercial companies (which do ultrasounds for “keepsake” purposes) are now creating more powerful ultrasound machines capable of providing popular 3D and 4D images. The procedure, however, lasts longer as they try to make 30-minute videos of the fetus in the uterus.
The main stream magazine New Scientist reported the following: Ultrasound scans can stop cells from dividing and make them commit suicide. Routine scans, which have let doctors peek at fetuses and internal organs for the past 40 years, affect the normal cell cycle.
On the FDA website this information is posted about ultrasounds:
While ultrasound has been around for many years, expectant women and their families need to know that the long-term effects of repeated ultrasound exposures on the fetus are not fully known. In light of all that remains unknown, having a prenatal ultrasound for non-medical reasons is not a good idea.
NATURE VERSUS NURTURE…THE DEBATE CONTINUES
Now that you are aware of some of the known factors which determine, improve, and impact the intellectual development of a fetus, it’s time for conception. Once that baby is born, which will be more crucial in the development of its intellect: nature (genetics) or nurture (the environment)?
Apparently for centuries, scientists and psychologists have gone back and forth on this. I read many comprehensive studies and reports on this subject during the research phase of this article, and I believe that it’s time to put this debate to rest. Both nature and nurture are equally as important and must be fully observed in the intellectual development of all children. This should never be an either/or proposition – why risk it?
A recent study shows that early intervention in the home and in the classroom can make a big difference for a child born into extreme poverty, according to Eric Turkheimer, a psychologist at the University of Virginia in Charlottesville. The study concludes that while genetic makeup explains most of the differences in IQ for children in wealthier families, environment – and not genes – makes a bigger difference for minority children in low-income homes.
Specifically, what researchers call “heritability”- the degree to which genes influence IQ – was significantly lower for poor families. “Once you’re put into an adequate environment, your genes start to take over,” Mr. Turkheimer said, “but in poor environments genes don’t have that ability.”
But there are reports that contradict these findings…sort of.
Linda S. Gottfredson, a professor of educational studies at the University of Delaware, wrote in her article, The General Intelligence Factor that environments shared by siblings have little to do with IQ. Many people still mistakenly believe that social, psychological and economic differences among families create lasting and marked differences in IQ.
She found that behavioral geneticists refer to such environmental effects as “shared” because they are common to siblings who grow up together. Her reports states that the heritability of IQ rises with age; that is to say, the extent to which genetics accounts for differences in IQ among individuals increases as people get older.
In her article she also refers to studies comparing identical and fraternal twins, published in the past decade by a group led by Thomas J. Bouchard, Jr., of the University of Minnesota and other scholars, show that about 40 percent of IQ differences among preschoolers stems from genetic differences, but that heritability rises to 60 percent by adolescence and to 80 percent by late adulthood.
And this is perhaps the most interesting bit of information, and relevant to this section of my article: With age, differences among individuals in their developed intelligence come to mirror more closely their genetic differences. It appears that the effects of environment on intelligence fade
