Pavlov's typology of higher nervous activity was the first systematic approach to the psychophysiology of individual differences.

The behavioral expressions of the Pavlovian constructs of CNS properties strength of excitation, strength of inhibition, and mobility of nervous processes as measured by the Pavlovian Temperament Survey (PTS) have been related to over a dozen personality dimensions

Pavlov's theory has been further developed by Teplov, Nebylitsyn and their pupils in the Institute of Psychology,Moscow. In particular, Nebylitsyn has delineated a new property of the nervous system and has shown that it is different from strength of the nervous system, in effect distinguishing between arousal and conditioning level
