Although he was a behaviorist who considered learned habits of great importance, he believed that personality differences grow out of our genetic inheritance. He is, therefore, primarily interested in what is usually called temperament. Temperament is that aspect of our personalities that is genetically based, and present from birth or personality test pdf free download before.
In devising a temperament-based theory Eysenck did not exclude the possibility that some aspects of personality are learned, but left the consideration of these to other researchers. According to Eysenck’s arousal theory of extraversion, there is an optimal level of cortical arousal, and performance deteriorates as one becomes more or less aroused than this optimal level. Arousal can be measured by skin conductance, brain waves or sweating. At very low and very high levels of arousal, performance is low, but at a better mid-level of arousal, performance is maximized. Extraverts, according to Eysenck’s theory, are chronically under-aroused and bored and are therefore in need of external stimulation to bring them UP to an optimal level of performance.
About 16 percent of the population tend to fall in this range. DOWN to an optimal level of performance. Neuroticism, according to Eysenck’s theory, is based on activation thresholds in the sympathetic nervous system or visceral brain. This is the part of the brain that is responsible for the fight-or-flight response in the face of danger. Emotionally stable people — who have high activation thresholds and good emotional control, experience negative affect only in the face of very major stressors — are calm and collected under pressure. The two dimensions or axes, extraversion-introversion and emotional stability-instability, define four quadrants. Psychotic behavior is rooted in the characteristics of toughmindedness, non-conformity, inconsideration, recklessness, hostility, anger and impulsiveness.
The physiological basis suggested by Eysenck for psychoticism is testosterone, with higher levels of psychoticism associated with higher levels of testosterone. Although the first 3 scales were predicted upon a biologically based theory of personality, the fourth scale has not been theoretically specified to the same extent, but it was considered to be conceptually strong to the extent that it would demonstrate the same degree of measurement similarity across cultures. EPQ also exists in Finnish and Turkish versions. Is the EPQ Lie Scale bidimensional? Validation study of the structure of the EPQ Lie Scale among Finnish and Turkish university students”.

Social media usage negatively correlated with trait reflectiveness. Social media usage negatively correlated with life goals in the morality domain. Similar correlations were found when examining participants’ texting habits. Correlations were consistent with previous studies and the shallowing hypothesis. The purpose of this study was to test key claims made by the shallowing hypothesis, while simultaneously advancing our general knowledge regarding the effects of social media usage. Participants completed an online questionnaire comprised of five measures that assessed their social media and texting behavior, use of reflective thought, life goals, personality dimensions, and demographic characteristics.
