Explain eysenck s approach to understanding personality

Ghosts seem to appear in all the circumstances in which our minds are at their least logical, least clear, and least sensible.

When personality goes from bad to good Some of the founding fathers of the psychology of personality wondered about this very question. View image of We usually think of personality in terms of the differences we see Credit: Eysenck and others believed that our personality largely comes from arousal levels in the brain and their ideas centred on differences between introverts and extroverts.

They would have been amazed and delighted at our recent understanding of how personality gets under our skin. Highly conscientious people are also less likely to be stressed Take the hormone cortisol, which is released when we get stressed. Early research linking cortisol and personality produced inconsistent results.

However, a study published late in overcame this problem by analysing cortisol levels in the hair of over 2, participants, who also completed personality questionnaires. The researchers cut off 3cm of hair from each volunteer, which provided a measure of cortisol that had accumulated over the last three months.

The higher that participants scored on the trait of conscientiousness which is associated with self-discipline, orderliness and ambitionthe lower the levels of cortisol in their hair. Importantly, the researchers also recorded how healthy participants were, looking at their diet, exercise and alcohol intake.

Conscientiousness correlated with healthier scores on all these measures, which makes sense, but importantly the link between hair cortisol and conscientiousness remained, even after factoring out differences in these health-related behaviours.

They are also more at risk of poor physical health. New findings show how this might be reflected at a surprisingly deep level within their bodies, in the microbacteria that live in their gut.

In another study published inresearchers analysed DNA from faecal samples, provided by volunteers who had also completed personality questionnaires. Even after controlling for differences in diet, the researchers found a small but significant association between higher scores on neuroticism and levels of Gammaproteobacteria, which include many pathogens.

Gammaproteobacteria include potentially harmful bacteria that tend to fit in the latter category. Raised levels can also be a sign of chronic inflammation acute inflammation helps the body cope with injury and infection, but chronic inflammation is harmful. Good microbes, in contrast, can contribute to health and are important for brain development.

That personality and the microbiome are linked could therefore help explain why people with a more neurotic, less conscientious personality are more vulnerable to illness than others. Open-minded individuals tend to lead more active, intellectually varied lifestyles The picture remains complicated, however, and these new studies are only preliminary.

However, we do know that the two are linked very early in life: Other markers of chronic inflammation in the body also relate to personality. A study of over 26, people found that individuals who scored high for conscientiousness also produced lower levels of certain proteins released by the immune system to fight disease, including C-reactive protein and interleukin-6, as measured by blood sample.

Higher openness associated with a willingness to try new things and aesthetic sensitivity was also correlated with lower C-reactive protein. The researchers believe the latter association might be because open-minded individuals tend to lead more active, intellectually varied lifestyles, which in turn, helps reduce their systematic inflammation.

However, aspects of our bodies that we are much more familiar with, including our blood pressure and heart rate, are also associated with personality. For instance, a study published in of over 5, British year-olds, found that those with hypertension were more likely to score highly on neurotic traits and low on conscientiousness, highlighting another route by which these traits may influence physical health.

Meanwhile, although a low-resting heartbeat is usually considered a sign of good physical health, when it comes to personality, the implications are darker.

Several studies have found that a lower resting heart rate correlates with higher psychopathy scores. People who match this description show superficial charm, fearlessness and impulsivity. This is not too surprising considering studies already link low-resting heart rate with aggressive and criminal behaviour.

As ever, more research is needed to test these ideas. Clearly our personality is deeply associated with the physical make-up of the body. In the not-too-distant future, it may be possible to measure personality in a completely different way. We may therefore soon see the biology of personality catching up with the psychology, as Gordon Allport hoped it would all those decades ago.

His next book, Personology, will be published in The trait approach to personality is one of the major theoretical areas in the study of personality. The trait theory suggests that individual personalities are composed of these broad dispositions.

Unlike many other theories of personality, such as psychoanalytic or humanistic theories, the trait approach to personality is focused on differences between individuals. Criminology is the scientific study of crime as an individual and social phenomenon. Criminological research areas in particular comprise the incidence and forms of crime as well as its causes and consequences.

They also include social and governmental regulations and reactions to crime. Eysenck’s approach is based in personality theory. In order to understand this we must consider that human behavior is determined by a series of attributes.

These attributes, or genetic traits, are the foundations of personality. Personality models on this page. The Four Temperaments/Four Humours. Carl Jung's Psychological Types. Myers Briggs® personality types theory (MBTI® model).
