This study was aimed to standardize the standard progressive matrices(SPM) test in the PC/S Vienna test system. The SPM test was administered to 295 adults in Seoul, comprised of 96university students, 111 adults of twenties and 88 adults of
thirties.
The test-retest reliability of the SPM with an interval of 2 weeks was found to be. 72. The internal consistency reliability of SPM as computed by Cronbach alpha was. 79. Product moment correlation between the full KWIS score and SPM was. 30. The
reliability and validity coefficients of the test were statistically significant.
No significant sex differences were observed in this study. And no significant cross-cultural differences were noted when comparing the computerized SPM results studied by Luxemburg and the results of this study. But significant age differences
were
found between twenties and thirties. The results suggested that increasing in age might be a key factor in lowering of intellectual function to adults.
According to the item analysis based on the item response theory, the results showed that the SPM consists of many easy items, but the average item difficulty, average item discrimination and average' guessing were in the moderate level.
Conclusionally, the SPM test may provide a culture-free, verbal-free promising tool for the measurement of nonverbal intelligence in Korean context. Future study will be extending to range of sampling to include all aged normal group, mental
retardation, other patients groups and industrial setting. In the future, SPM will be used to neuropsychological test in clinical settings.
