Raven's coloured progressive matrices in Japanese children: As a screening intelligence test for children with learning disorder and acquired childhood aphasia

Abstract

The aim of this study is to investigate use of Raven's coloured progressive matrices (RCPM) as an intelligence test for Japanese children. The subjects were 644 schoolchildren in second to sixth grades at two public primary schools in a city near Tokyo with a population of 400,000. The second-graders scored 29.5 on average with 5.6 as their standard deviation. Their scores became higher as the subjects got older, and the sixth-graders scored 33.0 on average with 3.8 as their standard deviation. Cronbach's alpha and the significant correlation between RCPM and WISC-III demonstrated that RCPM has both reliability and validity as an intelligence test for children. These data suggest that RCPM is appropriate for use as an intelligence test for Japanese children.
