Reference values of indicators for WHO neurobehavioral core test battery.

The reference values of the indicators for WHO neurobehavioral core test battery (NCTB) and the factors of age and sex on the performance preliminarily were analyzed. The results showed that there was a significant interference with the performance of behavior involved in hand movement and hand operation, a slight interference with the performance of behavior in simple reaction time, digit span and Benton visual retention, and almost no interference with the performance of behavior in mood due to age. It seemed that sex had hardly any effect on the indicators for WHO NCTB.
