Custom essays on Personality Psychology Hans Eysenck and his biological trait theory

Theoretical analysis showed that the theory of personality types is based on factor analysis. The hierarchical model of personality structure includes types, personality traits, habitual responses specific reactions. Types represent a continuum in which the two extremes are the characteristics of individuals. Eysenck emphasized that personality types are not discrete that most people do not fall under the extreme category.
The theory of types of Hans Eysenck developed on the basis of the mathematical apparatus of the factor analysis. This method assumes that people have different relatively constant personal qualities or traits, and that these traits can be measured by the correlation studies. Eysenck used the deductive method of scientific research, from theoretical considerations, and then collecting the data is logically relevant to this theory.
Eysenck placed special emphasis on the biological components of personality: according to his theory, the impact of the environment is practically no importance for the formation of personality. In his view, genetic factors have a much greater influence on subsequent behavior than children’s experiences. (Eysenck 1967)
The efforts to create a complete picture of Eysenck personality are worthy of admiration. Many psychologists consider him a first class professional, extremely professional in their attempts to create a scientifically based model of the structure and functioning of personality. All papers of Eysenck constantly emphasized the role of neurophysiological and genetic factors in explaining individual behavioral differences. In addition, he argues that an accurate measurement procedure is the cornerstone of building a convincing theory of personality.
It should also be noted his contribution to research in the field of criminology, education, psychopathology and behavior change.
Conclusion
Theories of personality based on factor analysis reflect the current interest in psychology to quantitative methods and, in turn, are reflected in the huge number of specially organized studies of personality.
In the field of psychotherapy Eysenck was one of the founders of behavioral psychotherapy. In terms of Eysenck theoretical basis and practical base behavioral psychotherapy aimed at changing in a positive direction modes of behavior and emotions of humans, modern learning theory and their fundamental laws.
Overall, it seems logical to conclude that the popularity of the theory of Eysenck has increased and will continue attempts of scientists to improve and expand his theory of personality traits on the theoretical and at empirical level.
