Hans Eysenck and Jeffrey Gray both proposed theories of personality that were based on the existence and measurement of specific traits. Eysenck's theory focused on three main dimensions (extraversion/introversion, neuroticism/emotional stability, and psychoticism). Gray expanded on Eysenck's theory by adding a fourth dimension related to the behavioral activation system (BAS) and behavioral inhibition system (BIS).
