In order for Hans Eysenck’s trait theory of personality to work, an assumption that behavior is determined by relatively stable traits must be made. The traits then become a fundamental unit of personality that will stay present in some way. This means people will always be predisposed to act in a certain way, no matter what the situation might be.
What is stable personality?
In the original trait theory of personality, Eysenck noted that people were stable would be emotionally calm, unreactive, and be unworried. Those who were unstable, which would fit into the neurotic dimension, would tend to be moody, anxious, and worry more often. People who were unstable would also be overly emotional and it would be difficult for them to calm down once they were upset.
What is extraversion in psychology?
Meanwhile, introverts’ psychic energy is projected inwards, leading them to indulge in inner-focussed, less sociable, activities ( Jung, 1921 ). Eysenck believed that extraversion is linked to levels of brain activity, or cortical arousal. Extraverts experience lower levels of cortical arousal, resulting in them seeking arousal from external ...

Higher arousal levels in introverts leads them to avoid stimuli which may lead to a further increase in arousal (Eysenck, 1979). According to the Yerkes-Dodson law, arousal levels can affect an individual’s performance abilities.

What is the relationship between neuroticism and extraversion?
Research on 16- to 70-year-old Americans conducted over a 2-year period showed that increasing satisfaction gained from work and social relationships was associated with a lower level of neuroticism and a higher level of extraversion (Scollon & Diener, 2006). Studies in Australia found that people who scored high in neuroticism on the Eysenck Personality Inventory outperformed those who scored low when their work environment was fast-paced and stressful. In other words, neurotics seem to function best in busy situations where they were forced to work harder (Smillie, Yeo, Furnham, & Jackson, 2006).
Why do introverts shy away from stimulation?
Eysenck was interested in how extraverts and introverts might differ biologically and genetically. He found that extraverts have a lower base level of cortical arousal than introverts do. Because the cortical arousal levels for extraverts are low, they need, and actively seek, excitement and stimulation. In contrast, introverts shy away from excitement and stimulation because their cortical arousal levels are already high (Eysenck, 1990b).
What is the body's alarm system?
People high in neuroticism have greater activity in the brain areas that control the sympathetic branch of the autonomic nervous system. This is the body’s alarm system, which response to stressful or dangerous events by increasing breathing rate, heart rate, blood flow to the muscles, and release of adrenaline. Eysenck argued that in neurotics, the sympathetic nervous system overreacts even to mild stressors, resulting in chronic hypersensitivity.
Why do men score higher on psychoticism?
Men generally tend to score higher on psychoticism than women, which led Eysenck to suggest that psychoticism may be related to male hormones. He also speculated that people who score high on all three dimensions may be apt to display criminal behavior but cited only modest empirical support for this idea (Eysenck & Gudjonsson, 1989).
What is neurotic personality?
Neurotics are characterized as anxious, depressed, tense, irrational, and moody. They may also have low self-esteem and be prone to guilt feelings. Eysenck suggested that neuroticism is largely inherited, a product of genetics rather than learning or experience.

What did Eysenck do?
Eysenck spent most of his career at the University of London’s Maudsley Hospital and Institute of Psychiatry, conducting research on the measurement of personality. He agreed with Cattell that personality is composed of traits, or factors, derived by the factor-analytic method. However, Eysenck was also a critic of factor analysis and of Cattell’s research because of the potential subjectivity in the technique and the difficulty in replicating Cattell’s findings. Although Eysenck used factor analysis to uncover personality traits, he supplemented the method with personality tests and experimental studies that considered a wide range of variables.
What does Eysenck believe about extraversion?
However, Eysenck believed that extraversion was related to levels of brain activity or cortical excitation. Extraverts experience lower levels of cortical excitation, which makes them seek excitation from external stimuli. The higher activation levels in introverts make them avoid stimuli that can lead to a great excitation.

What is the relationship between personality and biology?
Eysenck (1967, 1990) as cited in Maltby (2005) became one of the first theorists to link biology to personality. He suggested that within the brain there are two set of excitatory and inhibitory neural mechanisms. The excitatory relates to keep the individual alert, active and aroused. While the inhibitory mechanisms helps relates to inactivity and lethargy. He went on to say the individuals try to maintain an sense of balance between theses excite and inhibit mechanisms and this has been identified as ascending reticular activating system (ARAS). This is located in the brain stem; it connects to the thalamus, hypothalamus, and cortex. The ARAS handles the information or stimulation the brain receives. This is known as arousal according to Eysenck’s theory this can be attributed to two circuits reticulo-cortical this circuit controls the cortical arousal generated by incoming stimuli, as the reticulo-limbic circuit is responsible in how it manages arousal to emotional stimuli. Eysenck related arousal to his personality dimensions, extroversion and neuroticism. Neuroticism incorporates personality traits for instance anxiety, worry and moody traits, whereas extroversion has traits of sociability, sensations seeking carefree and optimistic. Gray’s (1970,1981) theory started as a variation to Eysenck theory but is now well thought-out and alternative theory. Grey’s theory places emphasis that biological mechanisms relate to things they desire. Grays findings were based on animal research to study human personality. Gray put forward that personality is based on communication between the Behavioral Approach System (BAS) and the Behavioral Inhibition System (BIS). The BAS has a tendency to seek rewards whereas the BIS tends to avoid punishment.
What are the Big Five?
Costa & McCrae’s (1976) developed this further with their big five model, Openness, extroversion, neuroticism conscientiousness & agreeableness. Eysenck’s argued against agreeableness and conscientiousness saying they belonged at a lower level in the hierarchy than psychoticism, extraversion, and neuroticism. Just as extraversion is made up of; impulsivity and sociability, so also psychoticism is made up of the factors agreeableness and conscientiousness. At the highest level in the hierarchy are the super factors P, E, and N. These super factors are not only psychometrically sound, but also have a physiological basis that has never been claimed for the Big Five.
What is the difference between neuroticism and extroversion?
Neuroticism incorporates personality traits for instance anxiety, worry and moody traits, whereas extroversion has traits of sociability, sensations seeking carefree and optimistic.

Why are extraverts so sociable?
They are more likely to take risks and be thrill seekers. Eysenck argues that this is because they inherit an under aroused nervous system and so seek stimulation to restore the level of optimum stimulation.

How are pleasure sources determined?
Sources of pleasure are determined by the location of the libido (life- force).
