Can Your Environment Affect Your IQ ?


Several studies have shown that physical growth and development of children are mainly governed by the provision of food with good nutritional content and a conducive environment. Researchers postulate that nutritional deficiencies can cause reduced IQ levels in children and consequently affect them when they reach adulthood.

Low birth weight and birth order have also shown to have a negative effect on a personís IQ. People with siblings generally have performed better on IQ tests than people without.

Studies show that the degree of parental rigidity plays an important role in a personís IQ. People whose parents were too rigid or too lax have generally lower IQ than people whose parents adopted a more balanced parenting style.

Studies also indicate that motherís education levels affect a personís emotional adaptation capabilities thereby affecting their IQ. Self confidence and attitude to life also play an important part in the development of a personís IQ.

These are again linked to a multitude of factors including parental and other social factors faced by them during their childhood years. In addition to the above factors such as increased reading skills, ambition also have an impact on a personís IQ.

Most studies show that no single environmental factor affects the IQ. They show that environmental effects on IQ are largely multi-lateral and hence difficult to quantify. Due to the largely unknown nature of brain functions scientists have not been able to accurately predict the relationship between IQ and various such factors.

However most scientists are certain that providing a caring and stimulating environment for children can help them mature into adults with reasonable levels of IQ. The effect of genetic factors on IQ is another area where research is currently ongoing.
