Biological Theories of Personality
Early theory (Eysenck): baseline arousal

Newer theory: rRST (revised reinforcement sensitivity model)
- Individual differences in brain activation and corresponding behaviors

Interactionism
The theory that behavior is determined jointly by situation and underlying dispositions
Rank-Ordering
