In vivo brain size and intelligence

It is widely believed that human brain size and intelligence are only weakly related to each other. Using magnetic resonance imaging, we show that larger brain size (corrected for body size) is associated with higher IQ in 40 college students equally divided by high versus average IQ, and by sex.

Zusammenfassung:It is widely believed that human brain size and intelligence are only weakly related to each other. Using magnetic resonance imaging, we show that larger brain size (corrected for body size) is associated with higher IQ in 40 college students equally divided by high versus average IQ, and by sex. These results suggest that differences in human brain size are relevant to explaining differences in intelligence test performance.
