Correlations between Intelligence and Neuropsychological Tests

Objects : In order to find what kind of brain function the intelligenece test reflects, the authors investigated the relationship between the intelligence tests and neuropsychological tests. Methods:The subjects were 56 patients including 6 psychiatric patients, 4 neurological patients and 46 brain-injured patients. Korean Wechsler Intelligence Scale(KWIS) was used for the assessment of intelligence. Halstead-Reitan neuropsychological test battery and computerized neuropsychological tests were used for the assessment of neuropsychological function. Pearson correlation coefficients between KWIS scores and the scores of neuropsychological tests were obtained. Results : Digit symbol test, spatial memory test, trail making test type A and Wechsler memory scale showed high correlation with total intelligence. These tests require simple attention ability and immediate memory of the subjects. On the other hand, tactual performance test, trail making test type B, stroop test, continuous performance test and Wisconsin card sorting test showed no correlation with total intelligence. These tests require more continuous attention ability and psychomotor coordination. Conclusion : According to our study, total intelligence seems to have some limitations in representation of more comprehensive brain function. However, by considering verbal and performance subscales of intelligence, it will be possible to obtain more precise decision about brain function of the subjects.
