Evaluation of eysencks trait theory of personality

Essentially physiology and genetics where mainly relevant in, Eysenck's theory Even though he was a behaviourist he considered that learned habits where of great importance, he also believed personality differences grew out of your hereditary inheritance. Working within these areas of personality Eysenck found out that there were two disciplines within psychology regarding personality. The first consisted of theorist who studied personality, interested in just developing ideas with hardly any empirical facts. The other used experimental data but had little if any interest in specific differences. This article will critically examine Hans Eysenck's trait theory of personality

Eysenck (1947) emphasized the importance of these two academic institutions of personality studies; to be included into one. However Eysenck's theories summarized in being able to identify and measure the dimensions of personality by using factor examination in which he devised a way to evaluate and test them.

Eysenck was for the most part a research psychologist, although he began investigating historical approaches to personality, these included the work of Hippocrates and Galen; his rationale for this was to discover the underlying engineering of personality. He found facts that, suggested there may be differences in personality types. He used this proof in his definition of personality. This is exactly what he used to build a personality inventory related to Galen's Four Temperaments.

However Eysenck's research provided a valuable additional compared to the four temperaments of Galen; by exploring and analysing the personality through dimensions, and made up from brains, physique and nervous system. Eysenck state was meet with scepticism from other theorist when he stated that there was a large natural determinant to personality. However his natural theories have been accepted from biological research carried out.

Eysenck surveyed thousands of people, by means of many various adjectives (attributes) representing behaviour as well as types. Eysenck (1970) created a scalable style of his personality test. He collected massive levels of research which comprised of using questionnaires, with these he collected his data; this helped him create his trait theory of personality, however unlike Cattell who accumulated his data first, then produced his theory previous, known as 'bottom up'. Eysenck began with the idea first and then created his data from his theory; this is excatly why Eysenck became known as a 'top down theorist. ' He used factor examination to obtain large quantities of data, for example provide a long set of adjectives to a considerable number of people. They are able to use these questionnaires to rate themselves on. Furthermore individuals who have high rating in anxiety should theoretically answer high on all stress related questions as cited in Maltby (2005). Using this method means only needing to ask fewer questions instead of a hundreds.

Using the personality questionnaire members were asked forty six questions where their answers stand for a true representation of these personality. Eysenck only recommended two traits then added his psychoticism characteristic later after studding psychologically ill patients this made his three features of personality that are known today extroversion, introversion and psychoticism these he called very traits.

Costa & McCrae's (1976) developed this further using their big five model, Openness, extroversion, neuroticism conscientiousness & agreeableness. Eysenck's argued against agreeableness and conscientiousness stating they belonged at less level in the hierarchy than psychoticism, extraversion, and neuroticism. In the same way extraversion comprises of; impulsivity and sociability, so also psychoticism comprises of the factors agreeableness and conscientiousness. At the best level in the hierarchy are the ultra factors P, E, and N. These super factors aren't only psychometrically acoustics, but likewise have a physiological basis that has never been stated for the best Five.

Costa and McCrae's (1976) as cited in Maltby (2005) related two features in their big five model, however Costa et al used cluster analysis rather than factor analysis which proved two main clusters which arranged with Eysenck's extroversion and neuroticism, they called these facets comparable to Eysenck's sizes. However because of the facets being narrow they guaranteed to form a level Costa et al created a fresh factor set to deal with this however now that lexical sampling was disappearing. Facet and factor were being assessed; they added two new factors agreeable, conscientiousness with their original three that they had taken from Goldberg. Costa and Crae used questionnaires which were known as the five factor style of personality (NEO-PI (R)).

traits such as extroversion, neuroticism, and psychoticism Eysenck uncovered that folks who scored high in extroversion also proved dimensions in their personality of outgoing, sociable, that they preferred company of others noisy and outgoing. Whereas neurotics exhibited measurements of shyness becoming unsociable prefer their own company calm and shy. Nonetheless when Eysenck discovered his third trait; psychoticism this exhibited visitors to be cruel, cold, impulsive, manipulative, etc. These types of personality may continue to develop mental ailments such as despair as well as schizophrenia unlike people who credit score low (warm, socialised).

Eysenck started by observing someone's tendencies this he telephone calls specific response, Eysenck used this to develop a hierarchical typology. For example by observing someone talking using their friends and carefully monitor their specific responses, the more that this person spends discussing with their friends they give away a few of the habitual reactions Eysenck thought that habitual replies are techniques individuals behave in certain situations. Furthermore he continued to claim that if you carried on observing them plus they may interact with others this would indicate that the average person likes to socialise, or they own a trait of sociability in their personality.

Eysenck argued that these attributes such as sociability, liveliness, activity, assertiveness and feeling seeking are highly correlated. To put it simply an individual's rating on each one of these traits will be related, these then learn to form a super characteristic of personality. Each excellent characteristic corresponds to a continuum which individuals can be located in order of the feature they possess.
