It is the study of three very different kinds of positive lives: Alternatively, extraverts show lower overall global activity, with reductions in the inferior orbital and prefrontal cortices.

Eysenck originally suggested that extraversion was a combination of two major tendencies, impulsiveness and sociability. No other areas of the brain revealed differences in blood flow while performing the CPT.This model is based on the reinforcement sensitivity theory by Jeffrey Alan Gray, which states that people with stronger behavioral activation system are high in reward responsiveness and are predisposed to the personality trait of extraversion, while people with a stronger behavioral inhibition system are lower in reward responsiveness and are more predisposed to personality trait of neuroticism and introversion.
