What are three environmental factors that affect intelligence quizlet?
Studies have shown that an older person's intelligence level can decline. Some of this has to do with biological changes. But such environmental factors as level of income, level of education, job experience, and other environmental factors can help older people maintain very high levels of intellectual functioning.
What are the factors influencing intelligence?
Even though the genetic susceptibility plays a crucial role on the IQ of the individual, various modifiable environmental factors like education, premature birth, nutrition, pollution, drug and alcohol abuse, mental illnesses, and diseases can have an influence on an individual's IQ.
Is intelligence genetic or environmental?
Numerous studies on twins suggest that between 40 and 80 percent of the variance in IQ is linked to genetics, suggesting that genetics may play a larger role than environmental factors in determining an individual's IQ.
What does evidence reveal about environmental influences on intelligence?
Where environments vary widely, environmental differences are more predictive of intelligence scores. Adoption enhances the intelligence scores of mistreated or neglected children. Intelligence scores of “virtual twins” (same-age, unrelated siblings adopted as infants and raised together) correlate +.

What is intelligence explain its types and explain the factors affecting intelligence?
Intelligence has been defined in many ways: higher level abilities (such as abstract reasoning, mental representation, problem solving, and decision making), the ability to learn, emotional knowledge, creativity, and adaptation to meet the demands of the environment effectively.
How does culture influence intelligence?
Culture and Intelligence Cultural knowledge increases the complexity of daily life, driving fluid intelligence. As information is transmitted from one generation to the next, humans have made culture cumulative. Meaning, no individual human can recreate their world within a lifetime (Muthukrishna & Henrich, 2016).
Environmental Influences on Intelligence Definition
Intelligence refers to the capacity of acquiring new skills, endowments of subjective knowledge, perception of facts, the capability of problem-solving, and the adaptive behavior of settling down in various types of environment. These intelligence levels are often influenced by environmental factors, which can be internal or external.
Overview of Environmental Influences On Intelligence
A lot of research has been done to investigate the impact of the environment on intelligence. The most common and significant factor in understanding the variation in human groups is the intelligence quotient. There are also other cognitive abilities to anticipate the influence of the environment on intelligence.
Determination of Intelligence by Genetics
Intelligence is a complex trait, which gets influenced by genetic and environmental factors. This concept is a bit challenging because intelligence levels are measured in different extents and manners. Researchers have observed that genes influence intelligence levels.
Influence of the environment on Intelligence Levels
Intelligence levels can be influenced by various environmental factors, such as family, peer groups, education, and the training provided to people. These environmental influences can be biological, non-biological, cultural, and social factors.

How does peer group influence intelligence?
The peer group an individual identifies with can also influence intelligence through the stereotypes associated with that group. The stereotype threat, first introduced by Claude Steele, is the idea that people belonging to a stereotyped group may perform poorly in a situation where the stereotype is relevant.
What does it mean when a child tells you they are intelligent?
Telling a child that they are intelligent and praising them for this 'intrinsic' quality indicates that intelligence is fixed, known as entity theory.
What is the role of peer group in IQ?
JR Harris suggested in The Nurture Assumption that an individual's peer group influences their intelligence greatly over time, and that different peer group characteristics may be responsible for the black-white IQ gap. Several longitudinal studies support the conjecture that peer groups significantly affect scholastic achievement, but relatively few studies have examined the effect on tests of cognitive ability.
How does the ordinal position of a child affect intelligence?
A number of studies have indicated that as birth order increases IQ decreases with first borns having especially superior intelligence. Many explanations for this have been proposed but the most widely accepted idea is that first borns receive more attention and resources from parents and are expected to focus on task achievement, whereas later borns are more focused on sociability.
What is the critical period for intellectual development?
The capacity of the brain to adapt its connections to environmental stimuli diminishes over time, and therefore it would follow that there is a critical period for intellectual development as well. While the critical period for the visual cortex ends in early childhood, other cortical areas and abilities have a critical period that lasts up through maturity (age 16), the same time frame for the development of fluid intelligence. In order for a person to develop certain intellectual abilities, they need to be provided with the appropriate environmental stimuli during childhood, before the critical period for adapting their neuronal connections ends. The existence of a critical period of language development is well established. A case illustrating this critical period is that of E.M., a young man who was born profoundly deaf and did not have any interaction with the deaf community. At the age of 15 he was fitted with hearing aids and taught Spanish; however, after 4 years he still had severe difficulties in verbal comprehension and production.
How much of the variance in intelligence is genetic?
It is estimated that genes contribute about 20–40% of the variance in intelligence in childhood and about 80% in adulthood. Thus the environment and its interaction with genes account for a high proportion of the variation in intelligence seen in groups of young children, and for a small proportion of the variation observed in groups ...

Recent research from the University of Wisconsin-Madison also suggested fossil fuel-powered air conditioning may contribute to roughly 1,000 additional annual deaths by 2050.
Why do children have lower IQ?
For children who have any environmental problems early on, such as lack of nutrients or exposure to toxins (as a result of their early surroundings), will go on to develop a lower IQ. 2. All I need is the air that I breathe…. Speaking of exposure to toxins, it is not just children who can suffer lower brain power.
Is it possible for the environment to alter our brainpower?
Is it really possible for the environment to alter our brainpower? Quite possibly! Have you ever been too hot to work, or maybe even too cold? These are just a couple of examples of environmental problems leading to an impact on our daily lives and our productivity. But, science now says that there is a direct link between those environmental problems and our intelligence.
Do children have high IQ?
Results showed that children are more likely to have a high IQ if they: Another major influence on intelligence, according to the study, is the level of cognitive stimulation the child receives at home. In addition, the ratio of encouraging comments made to children, versus reprimands, seems to have an influence on IQ.
Does pollution affect brain power?
Speaking of exposure to toxins, it is not just children who can suffer lower brain power. According to new research in China, as a result of increased levels of pollution, there were drops in test scores in language and maths. In fact, it had such an adverse effect that the average impact could be compared to having lost a year of school/college.
Why is the environment important for intelligence?
Environmental factors also play a role in intelligence, and children are more affected than adults by their environmental experiences. While both nature (biological) and nurture (environmental) factors play a role in intelligence, the environment impacts children more than adults. This is because the environment can directly impact brain ...
What are the biological influences of intelligence?
Biological Influences on Intelligence. Research links biological factors such as brain structure and function with intelligence. Brain structure shows a clear link to intellectual ability. Intelligence is correlated with a larger brain volume, more neurons, and a thicker cortex (outer layer of the brain).
What does the influence of nurture prove?
The influence of nurture proves that an individual's level of intelligence at birth is not completely fixed and unchangeable. Twins raised in the same home have more similar intelligence test scores than twins raised separately. Fraternal twins have the same degree of genetic similarity as ordinary siblings.
How does poverty affect brain development?
All of these factors can impair brain development and reduce intelligence. Children living in poverty may also be more likely to be exposed to toxins such as lead. Lead impairs brain development, negatively impacting language, social skills, intellectual ability, and basic coordination.
How do nature and nurture interact?
Nature and nurture also interact to predict outcomes. For example, a highly intelligent child may get more attention from teachers and extra enrichment opportunities than a child with less intelligence. These educational differences may enhance the initial biological differences.
How does speed affect intelligence?
People's speed on simple tasks, such as determining line length or pressing lit buttons, predicts intelligence. Working memory capacity, the ability to hold and process multiple pieces of information, also predicts intelligence. People who can work with more pieces of information simultaneously find it easier to solve problems.

Concepts from the fields of psychometrics, cognitive-experimental psychology , psychophysics, and biology that correlate with psychometric intelligence differences are described and discussed. It is noted that such correlations are numerous, often replicated, though usually modest in effect size.
What are the factors that affect intelligence?
There are only two factors that affect intelligence: genes and the environment. Since then, there has been a constant tug of war between the importance of “nature or nurture”, to assess a person’s mental and physical prowess. Whereas a person may inherit a certain set of genes, what happens to him/her depends upon environmental factors.
What is emotional intelligence?
In 1990, a couple of scientists/psychologists determined that emotional intelligence is an offshoot of social intelligence – having the ability to observe one’s and other people’s feelings or emotions. This is an ability to discriminate or guide one’s emotional thinking and therefore one’s actions. Since there are many facets ...

Neurological theory
As babies, our neuronal connections are completely undifferentiated. Neurons make connections with neighboring neurons, and these become more complex and more idiosyncratic as the child ages, up until the age of 16, when this process halts. This is also the time frame for development of what is defined in psychometric studies as the general factor of intelligence, or g, as measured by IQ tests. A person's IQ is supposed to be relatively stable after they have reached maturity. It i…
Environmental influence
Having access to resources of the home, and having a home life conducive to learning is definitely associated with scores on intelligence tests. However, it is difficult to disentangle possible genetic factors from a parent's attitude or use of language, for example.
A child's ordinal position in their family has also been shown to affect intelligence. A number of studies have indicated that as birth order increases IQ decreases with first borns having especia…
Biological influences
Nutrition has been shown to affect intelligence prenatally and postnatally. The idea that prenatal nutrition may affect intelligence comes from Barker's hypothesis of fetal programming, which states that during critical stages of development the intrauterine environment affects or 'programmes' how the child will develop. Barker cited nutrition as being one of the most important intrauterine influences affecting development and that under-nutrition could permanently chang…
Development of genius
It has been hypothesized that the development of genius in an area results from early environmental exposure to the topic in which the "genius" has prodigious knowledge or skill. This is utilizing the definition of genius that is not just a significantly higher than average IQ score, but also having some type of exceptional understanding or ability in a specific field. Albert Einstein is often used as an example of genius; he did not demonstrate generalized exceptional intelligenc…
