The Developmental Level (DL) score was assessed from Rorschach inkblot tests of 305 children. Children were either the offspring of one schizophrenic, one manic-depressive, one physically ill, or of two normal parents. Socioeconomic status, age, and intelligence were treated as covariates. Children of one schizophrenic parent had lower DL scores than children in the other three groups.
通过对305名儿童进行罗夏墨迹测验来评估其发育水平（DL）得分。这些儿童要么是一名精神分裂症患者、一名躁郁症患者、一名身体疾病患者的后代，要么是父母双方均正常的后代。社会经济地位、年龄和智力被视为协变量。有一名精神分裂症父母的儿童的DL得分低于其他三组儿童。
