vestibulocochlear nerve

the eighth cranial nerve: a sensory nerve containing tracts that innervate both the sense of hearing and the sense of balance. It has two divisions, the vestibular nerve, originating in the vestibule and the semicircular canals, and the auditory nerve (acoustic or cochlear nerve), originating in the cochlea. The vestibulocochlear nerve transmits impulses from the inner ear to the medulla oblongata and pons and has fibers that continue into the cerebrum and cerebellum. Also called cranial nerve VIII.

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.
