Summary
The study of cognitive abilities involves understanding the variance that exists between people, which can be measured through methods such as twin studies, specifically comparing identical and non-identical twins. By measuring cognitive abilities, researchers can determine the level of genetic influence, as identical twins will be more similar than non-identical twins.
