The Strelau Temperament Inventory as a broad classification system

The Strelau Temperament Inventory (STI) is an instrument designed by Jan Strelau to measure broad characteristics of the central nervous system. In a study reported here an American version of it was administered to a group of introductory psychology students, along with the 16PF test and an adjective check list. The findings of this study suggests that the STI does measure high and low reactivity in individuals and may have potential uses for the classification of temperament characteristics in individuals, particularly as a process of determining appropriate learning or behavioral strategies designed to enhance learning.
