2D:4D ratio and its association with examination scores and cognitive abilities in adolescent students - A cross-sectional study

Aims and Objectives: The objectives of the present study were to measure 2D:4D ratios of adolescent students and look for associations between 2D:4D ratios and their Higher Secondary School Board examination scores and their cognitive abilities such as attention, memory, spatial ability, and intelligence. Digit Ratio; 2D:4D Ratio; Cognition; Working Memory; Free Recall; Placement Recall; Prenatal Testosterone; Academic Performance INTRODUCTION A great deal of recent research has focused on the relationship between digit ratios (an index of prenatal androgen exposure) and various facets of health and disease. DISCUSSION Development and organization of the brain are influenced by the same prenatal androgens that determine 2D:4D. [...]differences in prenatal testosterone exposure may play a role in between and within sex differences in cognitive abilities. [...]effective comparisons and conclusions could not be performed and arrived at with the data of the present study.
