The Identification of Individual Differences in the Strength of the Nervous System. Report from the Project on Motivation and Individual Differences in Learning and Retention.
Severson, Herbert H.; Farley, Frank H.
This study investigates the hypotheses set forth by Russian researchers that there may be identified a pervasive characteristic of the central nervous system labeled as "strength". Ten of the 12 measures used were direct replications of representative strength measures derived from the Russian work. Two additional measures were included to test the possible relationship between strength and "arousal". Thirty-three graduate students were measured for Absolute Visual Threshold, Auditory Threshold, 2-Flash Threshold and Reaction Time, with the remaining variables derived by systematically varying experimental conditions. A factor analysis provided no clear-cut support for a dimension of strength although a number of less pervasive factors were obtained. The discussion centers around methodological issues and an apparent dimension of arousal. (Author/TL)
