Psychoticism and thinking.

In view of evidence linking psychosis with high creative ability, an attempt was made to evaluate the relationship between thinking abilities and personality traits. Tests of divergent thinking and convergent thinking were administered, along with the Eysencks' Personality Questionnaire, to 100 university students. The hypothesis that 'psychoticism' is related to divergent thinking was strongly confirmed. The hypothesis that psychoticism would be related inversely to speed in a convergent-thinking task was rejected. No evidence was found for any relationship between extraversion--introversion or neuroticism--stability and either thinking style.
