STUDIES IN PERSONALITY: A bio-psychological and experimental approach to problems of human adaptation in modern society

(a) Four hypothetical constructs of a theory of personality are defined within a biological frame of reference, (b) Three of the constructs are based on an experimental situation, (i) in which objective observations are made, and (ii) a scaling procedure utilized, which keeps cognitive factors constant. (c) Predictions concerning the genesis of normal or deviating development of the male personality are deduced and confirmed; i.e. predictions related to the genesis of 'neuroticism', 'delinquency', and their correlatives 'alcoholism' and 'accident-proneness'.
