Some Psychometric Problems of the Matching Familiar Figures Test
Administered were Kagan's Matching Familiar Figures Test and a group intelligence test to 151 male and 130 female Japanese 2nd graders, and detailed analyses of responses were made. While matching response time was high in internal consistency, errors were much less consistent. Variant positions were differentially selected by 4 groups, and the position where correct variants were placed partially accounted for “the error variance” of errors. But it seemed that errors of the matching test could not be made reliable enough simply by refining and lengthening the present version of Kagan's test. While slow-accurate, fast-accurate, and slow-inaccurate children adjusted their response time to item difficulty, fast-inaccurate children failed to do so. Almost all of these results were replicated in third and fifth graders. By the ordinary scoring method of intelligence test, the 4 matching groups differed from each other only in girls. But by adjusting the scores for errors, intelligence test performance came to correlate with the matching figures even in boys.
