MCAT Monday: Behavior - Theories of Personality


Biological, psychological, and sociocultural factors influence behavior and behavior change.


Human behavior is complex and often surprising, differing across individuals in the same situation and within an individual across different situations. A full understanding of human behavior requires knowledge of the interplay between psychological, sociocultural, and biological factors that are related to behavior. This interplay has important implications for the way we behave and the likelihood of behavior change.


Foundational Concept 7 focuses on individual and social determinants of behavior and behavior change.


With these building blocks, medical students will be able to learn how behavior can either support health or increase risk for disease. (via AAMC)
