Three lost genes would mean problems with heart, spatial reasoning and mental retardation.

While I am not bad at spatial reasoning, it isn't my strong point.

It's not, though: how would such a consistent difference in female spatial reasoning, across two otherwise nearly identical societies, arise?

I agree with those saying this study might actually support a biological difference in spatial reasoning between the sexes.

There may be other reasons that women in the matrilineal society do not outperform men on spatial reasoning.

The study shows, at most, that it is possible to achieve gender equality in spatial reasoning.

Researchers have now taken advantage of a rare situation to test how language development impacts spatial reasoning.

Suitable for those who enjoy puzzles, spatial reasoning, or headaches.

Behavioral geographers focus on the cognitive processes underlying spatial reasoning, decision making, and behavior.

On average men out perform women on spatial reasoning tests, which is theorized to result from sexual differences.
