In 2006, researchers Helga Dittmar, Emma Halliwell, and Suzanne Ive conducted an experiment testing how dolls, including Barbie, affect self-image in young girls. Dittmar, Halliwell, and Ive gave picture books to girls age 5–8, one with photos of Barbie and the other with photos of Emme, a doll with more realistic physical features. The girls were then asked about their ideal body size. Their research found that the girls who were exposed to the images of Barbie had significantly lower self-esteem than the girls who had photos of Emme.
