In psychology, the Eysenck Personality Questionnaire (EPQ) is a questionnaire to assess the personality traits of a person. It was devised by psychologists Hans Jürgen Eysenck and Sybil B. G. Eysenck. [1] Hans Eysenck's theory is based primarily on physiology and genetics. Although he was a behaviorist who considered learned habits of great ...
Psychoticism is conceptually similar to the constraint factor in Tellegen's three-factor model of personality. [1] Psychoticism may be divided into narrower traits such as impulsivity and sensation-seeking. These may in turn be further subdivided into even more specific traits.
He later developed his own arousal theory to explain individual differences in the trait, suggesting that the brains of extraverts were chronically under-aroused, leading them to seek out stimulation from the environment. [9] The trait of introversion-extraversion would become one of three central traits in Eysenck's PEN theory of personality. [10]
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.
The Temperament and Character Inventory (TCI) is an inventory for personality traits devised by Cloninger et al. [1] It is closely related to and an outgrowth of the Tridimensional Personality Questionnaire (TPQ), and it has also been related to the dimensions of personality in Zuckerman's alternative five and Eysenck's models [2] and those of the five factor model.
Personality similarities were found to be less related for self-concepts, goals, and interests. [49] Twin studies have also been important in the creation of the five factor personality model: neuroticism, extraversion, openness, agreeableness, and conscientiousness. Neuroticism and extraversion are the two most widely studied traits.
Personality and Individual Differences is a peer-reviewed academic journal published 16 times per year by Elsevier. It was established in 1980 by Pergamon Press and is the official journal of the International Society for the Study of Individual Differences.
Unlike Eysenck, Gray believed that personality traits and disorders could not be explained by classical conditioning alone. Gray proposed the Biopsychological Theory of personality in 1970 based on extensive animal research. [12] His theory emphasized the relationship between personality and sensitivity to reinforcement (i.e. reward and ...
