What are the environmental factors that affect intelligence?

In the present study, we found that various environmental factors such as place of residence, physical exercise, family income, parents’ occupation and education influence the IQ of a child to a great extent.

Does heritability or environmental influences affect levels of intelligence?

Today, researchers generally agree that heredity and environment have an interactive influence on intelligence. Heredity places an upper and lower limit on the IQ that can be attained by a given person. The environment determines where within these limits the person’s IQ will lie.

What evidence exists for a genetic component to an individual’s IQ?

What evidence exists for a genetic component to an individual’s IQ? Twin studies are one strong indication that IQ has a genetic component. Another indication is anecdotal evidence in the form of stories about highly intelligent individuals who come from difficult backgrounds yet still become highly successful adults.

What does evidence reveal about environmental influences on intelligence?

10-15: What does evidence reveal about environmental influences on intelligence? Studies of twins, family members, and adoptees also provide evidence of environmental influences. Males and females tend to have the same average intelligence test scores. They differ in some specific abilities.

What are the factors that affect intelligence?

Factors Affecting Intelligence

• Heredity and Environment:
• Age:
• Race and Nationality:
• Culture:
• Health and Physical Development:
• Sex:
• Social and Economic Conditions:

Which statement best describes the impact of genetics and environment on a child’s IQ?

Which statement best describes the impact of genetics and environment on a child’s IQ? At age two, maternal IQ best predicts the IQ of a child; by age four, the impact of the quality of the home environment becomes as good a predictor as maternal IQ.

Why You Think Different theorists defined intelligence in different ways?

Why do you think different theorists have defined intelligence in different ways? Since cognitive processes are complex, ascertaining them in a measurable way is challenging. Researchers have taken different approaches to define intelligence in an attempt to comprehensively describe and measure it.

What is the relationship between IQ scores and socioeconomic status?

Our results suggest that family socioeconomic status (SES) impacts children’s development of intelligence from infancy through adolescence. Children of the highest and lowest SES backgrounds were on average separated by 6 IQ points at the age of 2 years. By the age of 16, the IQ gap had almost tripled (Fig. 2).

What does evidence reveal about hereditary and environmental influences on intelligence quizlet?

Studies of twins, family members, and adoptees indicate a significant hereditary contribution to intelligence scores. Studies of children reared in extremely impoverished environments with minimal social interaction indicate that life experiences can significantly influence intelligence test performance.

How does nature and nurture affect intelligence?

Now, a study has shown that intelligence is a product of nurture as well as nature. Researchers found that children raised in wealthier and more educated households grow up to be smarter than those brought up in poorer homes.

Is the IQ gap genetic or environmental?

It’s not impossible to see substantial genetic changes that fast, but it’s unlikely. Speaking very generally, recent research suggests that the heritability of intelligence is about two-thirds biological and one-third environmental. That amount of environmental influence is more than enough to account for the black-white IQ gap.

Is the IQ gap between races and ethnicities narrowing?

An enormous body of evidence collected over the past 50 years shows that different ethnicities and races within a country tend to show substantial differences in their average level of IQ. Some researchers argue that this gap is narrowing (Dickens & Flynn, 2006) whereas others argue that the IQ gap has remained stable (Murray, 2006).

Why is there a black-white IQ gap?

That amount of environmental influence is more than enough to account for the black-white IQ gap. There’s a famous result in intelligence studies called the Flynn Effect. What it tells us is that average IQs rose about 3 points per decade throughout the 20th century.

What is the genetic background of people with low IQs?

The genetic background of all these countries is nearly identical, which means, again, that something related to culture, environment, and education is having a large effect. It is very common for marginalized groups to have low scores on IQ tests.
