3) Psychological point of view: Culture is the set of ideas, behaviors, attitudes, and traditions that exist within large groups of people (usually of a common religion, family, or something similar). These ideas, behaviors, traditions, etc. are passed on from one generation to the next and are typically resistant to change over time.
