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 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.

Do racial and ethnic groups differ in mental ability scores?

groups differ in mental ability scores. Racial and ethnic groups differ in their average intelligence test scores. The evidence suggests that environmental differences are largely, perhaps entirely, responsible for these group differences.

How stable are intelligence and test scores over the life span?

They have demonstrated that childhood cognitive ability accounts for 50% of the variance in cognitive ability in older age, 9 and that individual differences in intelligence continue to be stable across almost the entire human life span, into the tenth decade.

Are intelligence tests inappropriately biased quizlet?

are intelligence tests inappropriately biased? aptitude tests aim to predict how well a test-taker will perform in a given situation. so they are necessarily “biased” in the sense that they are sensitive to performance differences caused by cultural experience.

What is known about the relationship between IQ scores and environmental influences?

Conclusions: 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.

Is intelligence hereditary or environment?

Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors.

What is the relation between intelligence and creativity?

Although scientists have found a correlation between those individuals with an IQ of 120 or more having a higher level of creativity, the relationship between intelligence and creativity is more of an overlap of skills or abilities instead of a dependence on one another.

How stable is intelligence over your lifespan?

They have demonstrated that childhood cognitive ability accounts for 50% of the variance in cognitive ability in older age, 9 and that individual differences in intelligence continue to be stable across almost the entire human life span, into the tenth decade.

Are intelligence tests biased?

Tests can be biased in terms of impact (e.g., how they are used) and statistically. Tests can be biased if they treat groups unfairly or discriminate against diverse groups by, for example, “underestimating their potential or over-pathologizing their symptoms” (Suzuki et al., 1996, p. xiii).

What have researchers learned about intelligence from studying twins?

Genes have a very strong influence over how certain parts of our brains develop, scientists in the US and Finland have found. In identical twins, these areas showed a 95 to 100 per cent correlation between one twin and the other – they were essentially the same. …

What is the 10 year rule how do we apply it to intelligence?

First identified by the psychologist John Hayes in 1989 and soon endorsed by other psychologists, the rule states that a person must persevere with learning and practising a craft or discipline for about 10 years before he or she can make a breakthrough.

Does a correlation exist between brain anatomy and intelligence?

Overall, larger brain size and volume is associated with better cognitive functioning and higher intelligence. The specific regions that show the most robust correlation between volume and intelligence are the frontal, temporal and parietal lobes of the brain.
