Abstract

Ratio of Index Finger Length to Ring Finger Length (2D:4D) expressed a testosterone exposure during in prenatal. The masculinize the brain through prenatal testosterone exposure resulted a higher cognitive functioning. Previous studies shown a positive findings correlation between digit ratio (2D:4D) and cognitive functioning in gifted student sample. However rarely found study to correlate between the digit ratio (2D:4D) and working memory. We held a survey research among 22 female university students. To measure digit ratio we employed autometric software program. Working memory was tested using computer based Wisconsin sorting card test. Our result supported the correlation between digit ratio and working memory. Our finding implicated testosterone exposure influence working memory functioning. Mental health problem due to working memory functioning problem may detect and prevent with testosterone exposure
