Multiple levels of category inclusiveness in 4 object domains (animals, vehicles, fruit, and furniture) were examined using a sequential touching procedure and assessed in both individual and group analyses in eighty 12-, 18-, 24-, and 30-month-olds. The roles of stimulus discriminability and child motor development, fatigue, and actions were also investigated. More inclusive levels of categorization systematically emerged before less inclusive levels, and a consistent advantage for categorizing high versus low perceptual contrasts was found. Group and individual analyses generally converged, but individual analyses added information about child categorization over group analyses. The development of object categorization in young children is discussed in light of efficiency of processing and similarity-differentiation theories.
采用连续触摸程序，对四个物体领域（动物、车辆、水果和家具）的多个类别包容性水平进行了研究，参与者为 80 名 12、18、24 和 30 个月大的婴儿，评估方法包括个体分析和群组分析。还研究了刺激可辨别性、儿童运动发展、疲劳和动作的作用。更具包容性的分类水平系统地先于不那么具包容性的分类水平出现，并且发现了对高与低感知对比进行分类的一致优势。群组分析和个体分析总体上趋于一致，但个体分析提供了群组分析之外的有关儿童分类的信息。本文根据加工效率和相似性-差异理论讨论了幼儿的物体分类发展。
