Classification Behavior in Children Thirty-Six Months of Age.
Shimada, Shoko; Sano, Ryogoro
The purposes of this study were to examine the development of classification ability in 36 month olds and to clarify the positive relationship between classification ability and general cognitive development. Subjects, 16 Japanese children (8 males, 8 females), were individually tested by the use of 12 colored pictures of animals and vehicles. Tasks of spontaneous sorting and labeled sorting were administered with triad sets. The subjects' sorting abilities and verbalized reasons for his sorting choices were tested at 2 levels: basic categories such as dogs or cars and superordinate categories such as animals and vehicles. Results indicated that all the subjects named the objects at either the basic or subordinate level but none at the superordinate level. They were able to classify the materials easily at the basic level with a mean percent correct response rate of 92.7, but with difficulty at the superordinate level with a mean percent correct response rate of 52.1. Significant differences were obtained between the two spontaneous sortings and between the spontaneous superordinate sorting and the reasons at the basic level. The positive relationship between classification ability and general cognitive development as measured by the Suzuki-Binet Intelligence Test was confirmed. (Author/MP)
