Hans J. Eysenck's Five Factor Model

Summary Annotation

Hans J. Eysenck developed personality descriptions based on what he saw as physiological causes of personality to behavioral effects. He developed questionnaires that incorporated the concept of extraversion-introversion, neuroticism and psychoticism to develop his 3-factor model. This model is known as the PEN model. A five-factor model is an approach that was created based off of factors that many personality researchers have found within their own studies. Costa and McCrae are very well known for the OCEAN model. OCEAN is an acronym for openness to experience, conscientiousness, extroversion, agreeableness, and neuroticism.
"Personality structure among prisoners: How valid is the five-factor model, and can it offer support for Eysenck 's theory of criminality?" is a study that was created as a result of another study done before it. The previous study was based on research of offenders being done with the use of a

In comparing the two models there was hope "to validate a general personality structure within an offender sample to determine if there are any required adaptations of the FFM, and to ascertain if the FFM can offer some validation of Eysenck 's personality theory." With this study, the researchers had a few predictions that they hoped to prove. Researchers predicted that participants would show high levels of extraversion in their personalities and low levels of emotional stability in their scores which would prove high levels of neuroticism according to the PEN model. They also predicted that participants who had experienced a lot of time in prison would show low levels of extraversion. They predicted that younger prisoners would report higher levels of extraversion than the older prisoners and lastly they predicted that the FFM fits the data better than a three-factor PEN
