<P> The biopsychological theory of personality is similar to another one of Gray 's theories , reinforcement sensitivity theory . The Biopsychological Theory of Personality was created after Gray disagreed with Hans Eysenck 's arousal theory that dealt with biological personality traits . Eysenck looked at the ascending reticular activating system ( ARAS ) for answering questions about personality . The ARAS is part of the brain structure and has been proposed to deal with cortical arousal , hence the term arousal theory . Eysenck compared levels of arousal to a scale of introversion versus extraversion . The comparison of these two scales was then used to describe individual personalities and their corresponding behavioral patterns . Gray disagreed with Eysenck 's theory because Gray believed that things such as personality traits could not be explained by just classical conditioning . Instead , Gray developed his theory which is based more heavily on physiological responses than Eysenck 's theory . </P>
