Success in the fields of science, technology, engineering, and mathematics (STEM) is dependent in part upon an individual's cognitive ability in the areas of abstract mathematical reasoning and spatial reasoning. These abilities are related to prenatal hormone levels and can be estimated by measuring finger-size ratios. Specifically, the ratio between an individual's second and fourth digits (2d:4d) is inversely related to prenatal androgen exposure. Smaller 2d:4d ratios are associated with higher scores on m…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
