"Men are better at throwing darts (this was shown in an experiment that controlled for sports practice, but, sadly not for pub attendance), mentally rotating objects, and some other tasks related to spatial cognition."

"Some psychological tests also show the male advantage in systemising. For example, in the mental rotation test, you're shown two shapes, and asked if one is a rotation or a mirror image of the other. Males are quicker and more accurate on this test. Reading maps has been used as another test of systemising. Men can learn a route in fewer trials, just from looking at a map, correctly recalling more details about direction and distance. If you ask boys to make a map of an area that they have only visited once, their maps have a more accurate layout of the features in the environment, eg, showing which landmark is south-east of another.
If you ask people to put together a 3D mechanical apparatus in an assembly task, on average, men score higher. Boys are also better at constructing block buildings from 2D blueprints. These are constructional systems."

Of course, one of the leading hypotheses is that autism is an extreme form of the male brain.
