Objectives:

This study was conducted to develop the computerized higher function assessment tools for Korea adults. It also aimed at evaluating the reliability and validity of these tests and providing their normative data.

Methods:

Computerized versions of card sorting test, hypothesis formation test, color-word test, and finger tapping test developed through several steps of preliminary appications and corrections. The test-retest reliability of each test was evaluated by the paired t-test and Pearson's correlation coefficient using the data from 48 normal subjects. The normative data were obtained from the 150 Korean adults, age 20 to 50, whose educational levels were higher than high school graduate.

Results:

There were no statistical differences between the means of the test and retest scores except hypothesis formation test, which showed marked practice effect. High correlation were also observed between the test and the retest scores( r ranged from 0.543 to 0.905). The computerized higher cortical assessment tests scores were highly correlated with the scores of the pre-existing cognitive function tests, such as Standard Progressive Matrices. The scores of the card sorting test and the color-word test were not influenced by age, sex, and education level. However, the scores of the hypothesis formation were greatly influenced by the education level, nd the scores of the finger tapping test were greatly influenced by sex. The normative data and guidelines for interpreation were provided.

Conclusions:

Clinically applicable computerized higher cortical function assessment tools with high reliability and validity were developed. The normative data for the Korean adults aged 20 to 50 were obtaied and the guidelines for the interpretation were provided.
