Artificial neural networks are replacing traditional machine learning models. [11]) There is controversy, however, as to whether education affects intelligence it may be both a dependent and independent variable with regard to IQ.

Moreover, is it desirable--or even possible--to adapt Western tests to non-Western cultures, or should new tests be designed from the ground up to measure skills and abilities valued by the culture in which they are to be used? Air pollution is also thought to considerably affect the nervous systems of both children and adults. Avocado. Everyone inherits a mixture of genes. Is intelligence inherited, or does the environment play a larger role? This relationship has been harder to establish because the issue of malnutrition is often conflated with socioeconomic issues. This indicates that teaching incremental theory may improve performance on academic tasks, though further research is needed to investigate whether the same results can be found for general intelligence. Im definitely not one to blame everything thats wrong with us on our parents. A Norwegian study found that first born boys, on average, outscored their younger siblings on IQ tests, but only by two or three points. Stability appears to be an important portion of a childs upbringing when it comes to intelligence. [23] Early nutrition can also affect brain structures that are actually correlated to IQ levels. One possibility is that exercise increases blood flow to the brain, which can improve cognitive function.

The authors suggest that this could in part be because musicians from a young age translate visually perceived musical notes into motor commands whilst listening to the auditory output. It could be hypothesized that the effect of these drugs on the development of the brain prenatally, and axon guidance could be the root of the negative consequences on later deficits in intellectual development.
