Spencer's team tested more than 130 Kids in eight schools with very different racial and economic demographics. Half of the schools were on the north half in the south. While the country is much more diverse today than in the 1940s. The children in this project are from two age groups and two races, white and black. To better provide comparison to the original doll study. Four and five year old children were asked a series of questions about these images. Nine and 10 year old children were asked questions about the same images as well as this color bar chart. The tests led us to three major findings. First, white children as a whole responded with a high rate of what researchers called white bias identifying the color of their own skin with positive attributes and darker skin with negative attributes.
