Mamie Phipps Clark was an American social psychologist who, along with her husband Kenneth Clark, focused on the development of self-consciousness in black preschool children.
Clark was born and raised in Hot Springs, Arkansas.
Clark received her post-secondary education at Howard University and earned her bachelor's and master's degrees there.
For her master's thesis, known as "The Development of Consciousness of Self in Negro Pre-School Children," Clark worked with black Arkansas preschool children.
This work included doll experiments that investigated the way African American children's attitudes toward race and racial self-identification were affected by segregation.
It was found that children who attended segregated schools preferred playing with white dolls over black dolls.
The study was highly influential in the Brown v.
Board of Education court case.
It brought light to the effects of racial segregation on school-age children.
