Of the many psychologists who have viewed personality from a trait-factor perspective, three of the most influential are Gordon Allport, Raymond Cattell, and Hans Eysenck. Cattell's multifactor theory is perhaps the most comprehensive model of personality in terms of traits or factors, but Eyenck's model is the most parsimonious. Both conceptions are based on the results of factor analysis, a set of statistical procedures for determining what factors (psychological constructs) are sufficient to explain the correlations among a large group of scores on psychometric instruments. Whereas Cattell describes personality in terms of 16 or more source traits, Eysenck maintains that three "supertraits"—introversion—extraversion, emotional stability-instability, and psychoticism—are adequate to describe human personality.
