The Developmental Changes in Cube Copying Abilities of Japanese Children with Typical Development

Abstract

Purpose: The purpose of this study was to analyze the developmental changes in Necker cube copying and isometric perspective cube copying abilities of Japanese children of typical development.

Methods and Results: [Study-1] A total of 40 individuals aged 5-18 years participated in Study-1. The Necker cube copying task was administered, and scores were assigned based on the method developed by Yorimitsu et al. (2013). The results showed that the scores increased significantly for children in the 8-9 years age group (p < 0.01).[Study-2] A total of 32 individuals aged 6-10 years participated in Study-2. The isometric perspective cube copying task was administered, and scores were assigned based on the method developed by Otomo (2009). The results showed that the scores increased significantly for children in the 7-8 years age group (p < 0.05).

Conclusions: Japanese children of typical development were able to perform the Necker cube copying task from approximately nine years of age. The same participants were able to perform the isometric perspective cube copying task from approximately eight years of age.
