Baby girls make a beeline for dolls as soon as they can crawl - and boys will head for the toy cars.

The findings suggest there is a biological basis to their preferences.
这一发现说明，宝贝们的喜好选择是有生理前提的。
Psychologists Dr Brenda Todd from City University London carried out an experiment involving 90 infants aged nine months to 36 months.
伦敦城市大学的心理学博士布伦达托德进行了一项实验，这项实验由90名婴儿组成，他们的年龄在9个月到36个月之间。
The babies were allowed to choose from seven toys. Some were stereotypically boys' toys - a car, a digger, a ball and a blue teddy.
宝宝们可以从7件玩具中任选自己喜欢的玩具。这些玩具都是很典型的代表了性别特征的玩具，比如小汽车，铲子，皮球，和一个蓝色泰迪熊娃娃。
