The present study is part of a larger research project which is concerned with the cultural dimensions of interpretations of sexual differentiation in children's drawings. The basic assumption of this study is that the first figure drawn when a child is asked to draw a person is significantly related to, but does not necessarily establish, the sexual identification of the child. The primary intent of this paper is to introduce the cultural factor as a consideration in identity formation especially as it relates to sex-role preference. The Draw-A-Person Test in a modified form employing crayons was administered as a group test to 3201 children, from 3 to 17, of different ethnic backgrounds. The children were attending public and private schools in the New York Metropolitan area. The data showed the following: (1) all children did not necessarily draw their same sex first, (2) as children increased in age, the percentage of children who drew the same sex first increased, and (3) there were unexplained or unexpected fluctuations in the curves or percentages. It is suggested that the differences of the shapes of the curves reflect different cultural variables interacting with physiological variables. This is shown in the following findings: (1) at the earlier ages more females than males show same sex identification (2) during pre-adolescence there is little movement in the curve for the males while there is a decrease in the curves for females.This might mean that the process of sex identification for males is a slower process but without too much turmoil; while with females, pre-adolescence becomes a turbulent state. It is concluded that even if one accepts the premise that sex identification can be represented by drawings, there is no one-to-one correlation at any point. (Author/AM)
