Baby girls make their way directly for dolls as soon as they can crawl(爬), while boys will head for the toy cars, a study has shown. The findings—the first to show differences in very young babies—suggest there is a biological basis to their preferences.

Psychologists Dr Brenda Todd carried out an experiment involving 90 babies aged 9 months to 36 months. They were allowed to choose from 7 toys. Some were boys' toys—a car, a digger, a ball and a blue teddy. The rest were girls' toys; a pink teddy, a doll and a cooking set. They were placed a meter away from the toys, and could pick whichever toy they liked. Their choice and amount of time they spent playing with each toy were recorded.

Of the youngest children (9 to 14 months), girls spent much longer time playing with the doll than boys, and boys spent much more time with the car and the ball than the girls did. Among the two and threeyearolds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents' views on which toys were more appropriate for boys or girls, and the children's choices.

Dr Brenda Todd said, “Children of this age are already exposed to much socialization. Boys may be given ‘toys that go’ while girls get toys they can care for, which may help shape their preferences. But these findings are consistent with the former idea that children show intrinsic(内在的) interest in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to moving objects, probably through hunting instincts(本能), while girls prefer warmer colours such as pink, the colour of a newborn baby.”
