Ment Retard. 1990 Dec;28(6):359-66.
Eighteen children with mild mental retardation were pretested on unidimensional classification (oddity), unidimensional seriation, number conservation, Slosson's Intelligence Test, and the Peabody Picture Vocabulary Test (PPVT). The children were instructed on the Piagetian concepts twice per week for 4 months via a learning-set technique. All 315 problems (except 20 verbal classification and 15 verbal seriation items) involved concrete items. When posttested at the semester's end, the children had, with few exceptions, mastered the Piagetian concepts and made significant gains on performance on the PPVT.
对18名轻度智力发育迟缓儿童进行了单维分类（奇数辨别）、单维序列化、数字守恒、斯洛森智力测验和皮博迪图片词汇测验（PPVT）的预测试。通过学习集技术，每周两次、持续4个月对这些儿童进行皮亚杰概念的指导。所有315个问题（除20个语言分类和15个语言序列化项目外）都涉及具体项目。在学期末进行后测时，这些儿童几乎无一例外地掌握了皮亚杰概念，并且在PPVT的表现上取得了显著进步。
