Digit ratio (2D:4D) and muscular strength in adolescent boys.
Using a cross-sectional design, this study quantified the relationship between the digit ratio (2D:4D) and muscular strength in 57 adolescent boys. 2D:4D was very likely a moderate negative correlate of handgrip strength, even after adjustment for age and body size. This result may reflect the organizational benefits of prenatal testosterone.
متن کاملSecond-to-fourth digit ratio and facial shape in boys: the lower the digit ratio, the more robust the face.
During human ontogeny, testosterone has powerful organizational and activational effects on the male organism.

To t...
متن کاملDigit Ratio (2D:4D) and Handgrip Strength in Hani Ethnicity

متن کاملOverconfidence, Incentives and Digit Ratio
This paper contributes to a better understanding of the biological underpinnings of overconfidence by analyzing performance predictions in the Cognitive Reflection Test with and without monetary incentives. In line with the existing literature we find that the participants are too optimistic about their performance on average; incentives lead to higher performance; and males score higher than f...

Diagnostic Systems was employed in order to use residual sample intended for culture. Despite this tenfold dilution and the deliberate use of clinical specimens with few inclusions in culture, all culture-positive samples were also positive by Amplicor PCR. Falsenegative PCR results in other studies were possibly the result of inhibitors in the sample. In the present study, the further dilution...
