The Clarks used printed data sheets to record the children’s responses during the “doll test,” as well as general observations. This data sheet lists the nine questions that were routinely asked. The letters “B” and “W” denote “black” and “white.” The abbreviations “LB” and “DB” denote “light brown” and “dark brown” complexions. The data reveals that Mark A., a black boy age four with a dark brown complexion, prefers the white doll and selects the white doll as the one that looks like him.
