such activities as reading and playing the piano should be common to both genders
We can conclude from the passage that...... psychologists are attempting to eliminate sex discrimination in society
girls aren't given toy cars and train sets as presents, but anyway, they instinctively haven't much interest in them
the child's choice in games and toys is directed according to the norms of society rather than to his interests
the child only grows interested in the toys belonging to the opposite sex when there is a member of that sex in his or her vicinity
if the child's attention weren't drawn to such discrimination through prohibitions, he would instinctively behave suitably for his own gender
