Children of both genders were more prone to answer yes in regard to the man teacher than in regard to the woman teacher. Women are more nurturant to children than are men. In response to this question, the woman teacher usually won out. That's because the mother played a nurturant role for millions of years. I'm not saying that there weren't any mothers who weren't nurturant, I'm only saying that there weren't very many mothers who weren't nurturant but had children who survived long enough to pass their genes down to us.
Men are less verbal with children than are women.
Twist to your own convenience. Men are more conscious of gender differences than are women. A woman wrote to advice columnist because her husband wouldn't kiss their son. The wife thought her husband might be crazy for seeing their son as a stag friend rather than as a child. She had no reason for alarm, though.
