More than 70 years have passed since Dr. Kenneth B Clark and his wife Mamie designed and conducted the “doll test” to study the psychological effects of racism on young children.

They showed four dolls, identical except for color, to black children ages 3 to 7 and asked them questions to determine racial perception and preference. When asked which they preferred, the majority selected the white doll and attributed positive characteristics to it, leading the Clarks  to conclude that “prejudice, discrimination, and segregation” caused black children to develop a sense of inferiority and self-hatred.

In 2005, 18-year-old filmmaker Kiri Davis recreated the Clarks’ experiment with 21 young black children, and included footage of the testing in her short film A Girl Like Me. The stunning and disheartening results mirrored those in the Clark experiment so many decades earlier: [embedplusvideo height=”387″ width=”480″ standard=”http://www.youtube.com/v/zJJSps0CUr8?fs=1″ vars=”ytid=zJJSps0CUr8&width=480&height=387&start=&stop=&rs=w&hd=0&autoplay=0&react=1&chapters=&notes=” id=”ep3779″ /] “These children, even though they’re 4 and 5 years old, they’re kind of like a mirror and they show exactly what they’ve been exposed to by society,” Davis says. She hopes her documentary will help people see how subtle messages—like those in the media and through product marketing—continue to affect children. Knowing our children will be bombarded with negative images that  can undermine their ability to look in the mirror and admire what they see, we must remain ever diligent to ensure that they are receiving daily as many affirming messages about their beautiful selves as we can give them.

Removing terminology like “good hair” from our conversations is a great place to start in preventing the erosion of our children’s self esteem. Not using or allowing the words “black,” “African,” and “nappy” to be used as insults in our homes is also a must. And, while we’re at it, one truly powerful way to give our children positive feelings about themselves is to read, with love, uplifting stories that feature children whom they resemble. Here are 10 books parents, teachers and librarians highly recommend:

It should be noted that these are excellent books to read to all children, regardless of their ethnicity or skin tone. The messages in them are universal, and the positive exposure to brown skin as something to celebrate is a lesson every child can ultimately benefit from.

This is where the breaking down of old barriers and old stereotypes begins.
