Abstract

The ratio index finger length (2D) to ring finger length (4D) or digit ratio 2D:4D is a trait of sexual dimorphism. The prenatal testosterone influences the digit ratio 2D:4D since the growth of the fetus in the womb. High levels of prenatal testosterone will affect the development of finger which is indicated by the increasing size of the index finger. High testosterone levels are thought to be associated with aggressiveness in humans. This aggressiveness is often found in adolescence to adulthood such as collage students. This study aims to analyze the digit variation of the 2D:4D ratio and the relationship to aggressiveness in collage students. This research was conducted in January until March 2023 at the Sumatra Institute of Technology with a sample of 295 respondents representing three majors. The method used in this study is the assessment of aggressiveness data using the Buss-Perry questionnaire and measuring the digit ratio 2D:4D using a digital caliper. In this study, the results of the right and left digit ratio in males had a score of 0,9812 and 0,9827, and in females had a score of 0,9824 and 0,9909. This shows thus male’s digit ratio is lower than that of females. This study shows that the digit ratio is negatively correlated with physical aggressiveness. These results indicated a correlation between prenatal testosterone levels and aggressiveness, although it is not significant.
