The factors in the alternative Five model correspond to traits in Eysenck's three factor model, and to four of the five traits in the Five factor model.
According to the dimensional model, by contrast, the population at large is ranged along a normally distributed continuum or dimension, which has been variously labelled as psychoticism (H.J.Eysenck), schizotypy (Gordon Claridge) or psychosis-proneness.
Plus, he also drew more upon the likes of Ernst Kretschmer and Eduard Spranger, who had other models which he correlated with Galen's temperaments (though they were not necessarily perfect matches of them); while others followed Pavlov and Eysenck, who shaped the modern theories of those who held onto the Galenic names.
Gray's biopsychological theory of personality was informed by his earlier studies with Mowrer on reward, punishment, and motivation and Hans Eysenck’s study of the biology of personality traits.
Beside Gulenko's, there are several other theories of correlation between temperaments and socionic types, although almost all socionic authors support Eysenck's view that temperaments do correlate with the E/I factor.
Thought suppression is different from Freud's (1955) concept of repression, which is unconscious and automatic and has relatively little empirical support (see Eysenck, 1985; Holmes, 1990 for a review).
Hans Eysenck (1916–1997) was one of the first psychologists to analyze personality differences using a psycho-statistical method (factor analysis), and his research led him to believe that temperament is biologically based.
