In psychology, trait theory (also called dispositional theory) is an approach to the study of human personality. [1] Trait theorists are primarily interested in the measurement of traits , which can be defined as habitual patterns of behavior, thought , and emotion . [ 2 ]

Personality neuroscience uses neuroscientific methods to study the neurobiological mechanisms underlying individual differences in stable psychological attributes. . Specifically, personality neuroscience aims to investigate the relationships between inter-individual variation in brain structures as well as functions and behavioral measures of persistent psychological traits, broadly defined ...
