Nevertheless, most theories view personality as relatively stable.The study of the psychology of personality, called personality psychology, attempts to explain the tendencies that underlie differences in behavior.
Nevertheless, most theories view personality as relatively stable.
It measures personality based on Cattell's 16 factor theory of personality.
Psychologists also use it as a clinical measuring tool to diagnose psychiatric disorders and help with prognosis and therapy planning.
The temperamental theory suggests that extraverts have a disposition that generally leads them to experience a higher degree of positive affect.
In their study of extraversion, Lucas and Baird found no statistically significant support for the instrumental theory but did, however, find that extraverts generally experience a higher level of positive affect.
For the purposes of this study, positive affect is defined as experiences of happy and enjoyable emotions.
This study investigated the effects of acting in a way that is counter to a person's dispositional nature.Another interesting finding has been the link found between acting extraverted and positive affect.Extraverted behaviors include acting talkative, assertive, adventurous, and outgoing.These components are generally stable over time, and about half of the variance appears to be attributable to a person's genetics rather than the effects of one's environment.Some research has investigated whether the relationship between happiness and extraversion seen in adults can also be seen in children.All of these tests are beneficial because they have both reliability and validity, two factors that make a test accurate."Each item should be influenced to a degree by the underlying trait construct, giving rise to a pattern of positive intercorrelations so long as all items are oriented (worded) in the same direction." A recent, but not well-known, measuring tool that psychologists use is the 16 PF.In other words, the study focused on the benefits and drawbacks of introverts (people who are shy, socially inhibited and non-aggressive) acting extraverted, and of extraverts acting introverted.After acting extraverted, introverts' experience of positive affect increased whereas extraverts seemed to experience lower levels of positive affect and suffered from the phenomenon of ego depletion.The personality theorists consider temperament EAS model similar to the Big Five model in adults; however, this might be due to a conflation of concepts of personality and temperament as described above.Findings show that high degrees of sociability and low degrees of shyness are equivalent to adult extraversion, and correlate with higher levels of life satisfaction in children.
