Research Abstract

1.A Japanese Short-Form of the Swanson Cognitive Processing Test (JS-CPT).
The reliability and validity of a Japanese short-form of the Swanson Cognitive Processing Test (JS-CPT) was investigated, a test that assesses the working memory capacity. Test-retest reliability of the JS-CPT was within an acceptable range (r=.76,p<.01). Concurrent validity of the JS-CPT was confirmed through the comparison of the scores on the Reading Span Task (r=.55,p<.05). JS-CPT samples were comparable with S-CPT samples on the 3 subtests for older group and the 2 subtests for younger group. With an exception of the Auditory Digit Sequence task, the results showed that both JS-CPT and S-CPT had measured comparable abilities of working memory in child populations.
2.The relations among Reading, Phonological Awareness and Working Memory in Normal 4th to 6th grade children.
The Construct Model of Ishizaka et al. (2004) on the relationships among the reading ability, phonological awareness and auditory working memory in 4th-6th grade children of elementary school was examined.
Neither phonological awareness nor auditory working memory was the predictors of reading ability. By our multiple regression analysis using four tasks, the three of them could be the predictor of reading ability. We found that the auditory digit sequence and phonological deletion tasks were predictors of reading ability. That means these tasks measure different aspects of phonological awareness or auditory working memory.
