Chess and Gender?

Via Son of Pearl's Chess Blog where he has the post What Sex is Your Brain? we found the Sex ID Test. I am curious how ability at different tasks maps to ability at chess. Are men better than women at skills useful in chess? Some excerpts of my results:

This task tested your ability to identify the angle of a line by matching it with its twin. This is a spatial task, which looks at how you picture space.
Your score: 20 out of 20
Average score for men: 15.1 out of 20
Average score for women: 13.3 out of 20

If you scored 18 - 20: You have more of a male brain.

Spot the difference
This task tested your ability to identify which objects changed position. You lost points, if you incorrectly identified objects.
Your score: 71%
Average score for men: 39%
Average score for women: 46%

If you scored between 67 - 100%: Those with a female-type brain generally score in this range.

Your systemising score is: 17 out of 20
Average score for men: 12.5 out of 20
Average score for women: 8.0 out of 20

Men in general are better at systemising.

3D shapes
This task tested your ability to mentally rotate 3D shapes.

Your score: 7 out of 12
Average score for men: 8.2 out of 12
Average score for women: 7.1 out of 12

If you scored 7 - 9: In past studies, 50 per cent of the people who scored in this range were women and 50 per cent were men.

Son Of Pearl:I did well in the angles test (19 out of 20), and the test where you have to mentally rotate a 3D shape and match it to others (11/12), which should mean that I have some of the skills needed to be a good chess player.

We both did well at angles but he aced me on the 3D Shapes. Which, if any, of these tests map to ability at chess?

To the extent there are differences between men and women in these areas and in chess how much of that is genetic and how much is environmental? Hey. It might be interesting to see what Anand thinks about all of this.

Remember, if you have Questions for World Champion Anand record them in the comments to that post.
Happy Thanksgiving!
I didn't do as well on the angles and shapes things as I expected. Maybe it was the wine with dinner, or being over 50. LOL

After college I had considered going into the Navy, and took the aptitude test. I scored very high on the spatial part which involved looking at flat shapes and determining which 3 dimensional shape matched.

I wonder if this relates to my chess decline. :-O
