As someone who works with kids (ages 7-18), I'll comment from my own experience. There isn't a lot of difference. I can't deny there some mild tendency of boys and girls acting differently in the ways described above. BUT, in a "free" environment (which is where I work) that difference is so small that I really can't say whether it's caused by latent external expectations of society and the parts thereof that still haven't caught on to the huge importance of emancipation and compassion, instead of by some intrinsic factor of the biology of the kids themselves.
That said, I can't really scientifically/rationally 100% dismiss it either.
HOWEVER, there is one really important takeaway from this, which is separate from whether it's biological or not. There may be a tendency, but it is vastly overshadowed by differences in character between individuals, which do exist, and it's important to be mindful and aware of those. If left to their own devices without too much external pressure, I see "girly" boys and "boyish" girls (ranging from minor personality traits and interests to wearing different clothes, make-up, hairstyles, jewelry). Everyone is all over the spectrum, really. And that's beautiful.
In my line of work (teaching kids computer and technology stuff), there is a group of (mostly older) women working actively to focus on girls' interest for technology. Which is a noble cause, of course. And they're doing great work ... if it was last century, when this seemed like a good idea in emancipation/feminism. They don't get it if I comment on this, think I am on the wrong side of this battle. But by focusing purely on girls, trying to show them there is also "cool stuff for girls" to do in technology, they are so doin' it wrong .. What about the "girly boys" that would love to take part in activities like this? They got left behind. What about the "boyish girls" that think this stuff is boring and would rather build a action-packed videogame or learn about XSS and SQL-injections ..
So yeah, my point is, biological tendencies or not, they are (in my anecdotal experience) vastly overshadowed by individual personality characteristics.
