This report discusses the outcomes of a study that examined a hypothesis about the acquisition of behavioral inhibitions offered by Hans Eysenck, which suggests that what is often described as morality or conscience is acquired through conditioning experiences to which individuals respond differently according to their temperament-based personality traits. Eysenck's theory of personality has three temperament-based traits: Psychoticism (P), Extraversion (E), and Neuroticism (N). He suggests that individuals who are low on both E and N traits will be more likely to acquire behavioral inhibitions than individuals who are high on both traits. All participants in the study (n=98) were suspended from middle or high school for disciplinary reasons and attended a transitional learning center as an alternative to an out-of-school suspension. Two instruments were administered to the participants: the Junior Eysenck Personality Questionnaire to assess personality and the Externalizing Scale of the Youth Self-Report to assess self-reported conduct problems. Results from the assessments indicate students low on both the E and N traits had lower scores on the Externalizing Scale than those high on both traits. (Contains 30 references.) (CR)
