Bloody hell! if I lived anywhere near London, DD and I would be off there to point and make loud comments. Though actually she's too busy, doing A levels in double maths and physics.
She hasn't got 'boy brain' - she's just grown up being herself, though with less stereotype threat and peer pressure than many (I'm a scientist who's good at maths, her primary school had excellent female science and maths specialists, girls secondary where the science/maths/tech activities are clearly for girls...). To be clear, I'd be just as happy if she was into stereotypically 'female' subjects, its her life, her personality.
Incidentally, using Google scholar 'Your search - "brain sex" "pictures of fruit" - did not match any articles.' . Now there's a suprise.
