The correlation between prenatal androgenization exposure and spatial intelligence

 The testosterone-2d:4d ratio is a measure of the length of the second and fourth digits of the hand, which is believed to be an indicator of prenatal androgen exposure. Research has shown that individuals with a lower 2d:4d ratio, indicating higher prenatal androgen exposure, tend to have better spatial ability. Spatial ability is the capacity to understand and manipulate visual and spatial information, and it is an important component of intelligence.

 The relationship between prenatal androgenization and spatial ability-intelligence has not been extensively studied, and this is where my investigation comes in. By examining the correlation between the testosterone-2d:4d ratio and spatial ability-intelligence, I aim to shed light on the potential role of prenatal androgen exposure in determining spatial intelligence. 

To conduct this investigation, I will collect data from a simple random sample of students at our highschool and measure their PNA(prenatal androgenization exposure)-2d:4d ratio, as well as their spatial ability and intelligence. I will then analyze the data to determine whether there is a significant correlation between these variables. 

The findings of this study could have important implications for understanding the factors that contribute to individual differences in spatial ability and intelligence. If prenatal androgen exposure is found to be a significant predictor of spatial ability-intelligence, this could have implications for educational and occupational settings, as well as for understanding the underlying mechanisms of cognitive development. Overall, this investigation has the potential to contribute to the discourse on the relationship between prenatal androgenization and cognitive development, and to advance our understanding of the factors that shape individual differences in intelligence.
