Does the gender of a baby affect its preference for toys?
The hypothesis that baby boys prefer trucks and baby girls prefer Barbie dolls, is proven to be true.
Baby girls and boys as young as 6 months old may not be able to recognize and differentiate gender yet. Therefore the above results should theoretically be free from social influencing. Some researchers believe that the behavioral preferences of baby girls and boys, as observed in the above experiment, may be hard wired in babies, either genetically or perhaps through hormones.
The science fair project can be repeated using older 18 month-old babies ts.
Try to repeat the science project experiment using a Barbie doll and a GI Joe doll instead of trucks. Would there be any difference in your results?
