Environmental Factors That Determinants Intelligence

Intelligence

Intelligence is a complex trait that is influenced by both genetics and environmental factors. Studies indicate that 30–75% of IQ variations can be attributed to genes, while environmental influences determine how much of the potential genetic intelligence is achieved during a person’s lifetime.

The home environment is a major environmental factor that shapes the development of an individual’s intelligence. For example, children raised in homes with a higher socioeconomic status exhibit higher IQ scores than those raised in lower-income homes.

Malnutrition

Malnutrition is a global health issue and the number of people in poor countries suffering from different forms of malnutrition continues to increase. Approximately 149 million children under 5 are stunted (too short for their age) and 45 million are wasted (too thin for their height).

Child malnutrition affects cognitive, behavioral and mental health outcomes in survivors across the lifespan. Fortunately, improved treatment has helped more children with malnutrition to thrive and survive into adolescence and adulthood.

Although many studies have found that early childhood malnutrition is associated with poorer IQ levels, school achievement and behavioral problems, less is known about the impact of malnutrition on later life outcomes.

A study of 86 previously malnourished children in the Barbados Nutrition Study provided an opportunity to investigate long-term effects of childhood malnutrition on adult IQ and academic achievement. The case-control design compared the performance of a previously malnourished group to that of healthy children from the same neighborhoods and classrooms. The study also collected data on socioeconomic circumstances at multiple time points throughout childhood and adolescence, so that potentially confounding effects of standard of living could be estimated.

Toxic Substances

Toxic substances can damage the brain and cause a wide range of health problems. They can also cause mental and behavioral disorders such as autism, ADHD, and dyslexia.

To avoid these effects, it is important to keep your home, workplace, and school free from harmful chemicals. It is also important to monitor your children for any signs of poisoning, such as slowed growth and delayed development.

In addition, if you are pregnant or thinking of getting pregnant, you should avoid consuming certain dietary and cosmetic products that contain toxic ingredients. These can harm your child’s developing brain and affect their intelligence.

Toxic substances can be flammable, corrosive, or chemically toxic, which means they can cause injury or death if they are swallowed, breathed in, or come into contact with the skin. They can have both acute and chronic effects, which can happen at different times after exposure. Acute effects appear instantly after exposure, while chronic effects can take hours, days, months, or years to show up.

Noise

Noise is a stressor that can negatively affect the brain, leading to mental and physical health problems. It can also impede learning, distract students and reduce their motivation in the classroom

Researchers have recently shown that noise exposure has a significant effect on children’s cognitive development. A study of schoolchildren in Barcelona, Spain, Nigeria found that those who were exposed to a greater amount of traffic noise progressed slower in working memory and attention tests than those who were less exposed.

The researchers said that this finding adds to the body of research on transport and how it affects children’s cognitive development. But they also stressed that future studies on road traffic noise in other populations should determine whether these initial findings can be extrapolated to other cities and settings.

The researchers used EEG signals to study the effects of noise on cognitive performance and brain activity. They evaluated the impact of 75, 85 and 95 dBA levels on mental workload and auditory/visual attention. They found that the effect of noise on these measures was significantly smaller at lower than TLV noise levels (45, 75 and 85 dBA).

Social Interactions

Social interactions play a major role in human interaction and have an effect on the overall quality of life. Several studies have shown that people with higher social intelligence are more likely to have good interpersonal relationships, have more supportive relationships with family and friends, and experience less stress at work.

This is due to the fact that they are better able to understand how others feel. They also have the ability to communicate effectively with others and are able to listen to other people’s ideas without immediately jumping to conclusions. In order to investigate the effects of social interactions on social intelligence, we used a diary study in which participants describe their daily social experiences. The descriptions were analyzed to identify features of social interactions that are ecologically valid.
