Explanation:

Personality refers to the cognitive, behavioral, and emotional patterns of a particular individual. It has been shown that personality traits can be influenced by both biological (i.e., genetic) and environmental (e.g., cultural, educational) factors. People can be classified into two basic personality types: 1-introverts (turned inward) and 2-extroverts (turned outward).
