Costa and McCrae believe that agreeableness and conscientiousness (both of which represent low levels of psychoticism) need to be distinguished in personality models. [3] It has also been suggested that "psychoticism" may be a misnomer and that " psychopathy " or "Impulsive Unsocialized Sensation Seeking" would be better labels.
Eysenck's three-factor model of personality was a causal theory of personality based on activation of reticular formation and limbic system. The reticular formation is a region in the brainstem that is involved in mediating arousal and consciousness. The limbic system is involved in mediating emotion, behavior, motivation, and long-term memory.
In his book Dimensions of Personality (1947) he paired Extraversion (E), which was "the tendency to enjoy positive events", especially social ones, with Neuroticism (N), which was the tendency to experience negative emotions. By pairing the two dimensions, Eysenck noted how the results were similar to the four ancient temperaments.
