hierarchical model of personality

a model of either within-person dynamics or individual differences in personality in which some psychological constructs are viewed as high-level variables that organize or govern the functioning of other lower level variables. For example, a hierarchical model of personality traits might view the construct sociability as being at a lower level in a hierarchy than the construct extraversion: Sociability would be seen as a form or example of the higher level trait of extraversion.
