thumb The biological basis of personality is the theory that personality is influenced by the biology of the brain. Though closely related to personality psychology, the biological basis of personality focuses on ''why'' or ''how'' personality traits manifest through biology, in addition to identifying personality traits. This is investigated by correlating personality traits with scientific data from experimental methods such as brain imaging and molecular genetics. Much of the current understanding of personality from a neurobiological perspective places an emphasis on the biochemistry of the behavioral systems of reward, motivation, and punishment. This has led to a few biologically based personality theories such as Eysenck's three factor model of personality, Grey's reinforcement sensitivity theory (RST), and Cloninger's model of personality. The Big Five model of personality is not biologically based; yet some research in the differences in brain structures provided biological support also for this model. ==Defining Personality in Biological Context== Personality can be defined as a set of characteristics or traits that drive individual differences in human behavior. From a biological perspective, these traits can be traced back to brain structures and neural mechanisms. However, this definition and theory of biological basis is not universally accepted. There are many conflicting theories of personality in the fields of psychology, psychiatry, philosophy, and neuroscience. A few examples of this are the nature vs. nurture debate and how the idea of a 'soul' fits into biological theories of personality. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Biological basis of personality」の詳細全文を読む スポンサード リンク
