Intelligence encompasses both genetic and environmental contributions.
Is intelligence genetic or environmental?
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors. Intelligence is challenging to study, in part because it can be defined and measured in different ways.
How do genetics and the environment influence intelligence quizlet?
Environmental factors determines which genes get switched on. … The data show that both genetics and environment have an effect on IQ scores. The more closely two individuals are related genetically, the more similar their IQ scores: Identical twins reared together are more alike than are fraternal twins reared together.
Is intelligence inherited quizlet?
An individual’s IQ is influenced by genetics, but a group’s IQ is influenced by culture.
Where does high intelligence come from genetics or environment?
We found that high intelligence is familial, heritable, and caused by the same genetic and environmental factors responsible for the normal distribution of intelligence.
Can intelligence Be Inherited?
General intelligence definitely runs in the family. Twin studies (on both identical twins and fraternal twins) have found a heritability of IQ between 57% and 73%, and in some cases, even higher. Interestingly, genetic studies have revealed that a child’s IQ score is less affected by intelligence genes than an adults.
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 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.
What is one piece of evidence that intelligence has a genetic component?
Evidence of Genetic Influences on Intelligence
Studies show that IQ scores of identical twins may be more similar than those of fraternal twins. Siblings who were raised together in the same environment have more similar IQs than those of adopted children who were brought up in the same household.
What is the promise of molecular genetics research?
what is the promise of molecular genetics research? molecular geneticists study the molecular structure and function of genes, including those that affect behavior. Psychologists and molecular geneticists are cooperating to identify specific genes – or more often, teams of genes – that put people at risk for disorders.
What are three 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.
