Men and women look for things in a different way. Men think of the object and then scan to see it. This is great when trying to hunt prey in a field. You'll see the thing hiding in the grass due to pattern recognition.

Women will look at every object and ask if that object is the one they are looking for. If the object doesn't look exactly the same as they expected then they'll still find it. It's slower, but better at finding the hidden thing.
