1 PSYCHOLOGYThe aim of the essay is to discuss with evidence how do the Eysenck and the Graytheories of 'E' and 'N' agree, and how do they differ? The essay discusses if either model iswell discussed with evidence. Eysenck and the Gray theories hypothesised that personalitytraitsaid in understanding the differences in brain functioning in an individual. Both thetheories assumed that the brain process can be characterised by themeansofa simplifiedconceptual nervous system, which contains circuits of personality and behaviour (Zuckerman,2014).Eysenck's Extraversion - Stability model or E model favours only two dimensions,which are Extraversion – Introversion and the stability – Instability. This theory emphasisedon biological basis of the personality traits. Eysenck's studies found many links between theStability - instabilityand the Extraversion – Introversion and were associated with differencesin the pattern of arousal in brain of an individual. The studies concluded that extrovert peoplehad low level of arousal in brain and they engage in high level of social contact for achievingan optimal level of cortical arousal. On the contrary, the introvert people have high level ofarousal within brain (Claridge, 2016). The studies of Gray agreed on the differences in arousal levels linked with stabilityand instability. Gray highlighted that people with stable nervous system/Neuroticism-stabilityor “N” have less significant or a gradual shift in the arousal and vice versa in unstable people.Gray developed the Reinforcement sensitivity theorybased on biological analysis at startingpoint. On the other hand, Eysenck's studies established the theory and later made theconnections to the biological aspect on this note both the theories differ (Hundt et al., 2013).According to Gray the different personality of human beings is due to variations of internalfactors of rewards and punishments. This inner biological system has variations of sensitivitythat gives rise to differences in personality. Gray’s theory emerged as alternative to theEysenck's studies (Jappe et al., 2011).
