Dr. Mamie Phipps Clark
Mamie Phipps Clark’s groundbreaking work in child psychology played a pivotal role in the Civil Rights Movement, providing eye-opening insights into how children experience racism. In her master’s thesis, she surveyed 150 Black preschoolers in Washington D.C. to explore issues of race and child development—asking specifically about the age at which they became aware they were Black.
Later, along with her husband, Kenneth Clark, she developed the famous “Doll Test,” which evaluated 253 Black children from three to seven years old. Within this group, 134 attended segregated nursery schools in Arkansas, and 119 attended integrated schools in Massachusetts. After being shown four dolls—two with white skin and yellow hair, and two with brown skin and black hair—each student was asked which doll they preferred to play with. The majority of the Black children preferred the white doll with yellow hair and assigned positive traits to it yet discarded the brown doll with black hair and assigned negative traits to it. Ultimately, the Clarks’ research helped shape the Supreme Court ruling in Brown v. Board of Education that led to the desegregation of schools.
