Activity level and sex-stereotyped toy choice in toddler boys and girls.

In the first study, the motor activity level and vigor of play of 52 toddlers was assessed as they played with a set of sex-role stereotyped and neutral toys. Boys and girls showed the same level of activity, and both were significantly more active when playing with stereotypically masculine toys. In the second study, 27 toddlers were observed playing with toys defined as potentially eliciting high, medium, or low activity within the masculine, feminine, and neutral categories. Again, boys and girls did not differ in overall activity level. All children preferred toys that allowed moderate to high activity, but given this preference, they selected toys stereotyped for their own gender above those stereotyped for the other gender.
