Final answer:
The Eysenck personality type characterized by sociability is called extroversion. Extroverts are outgoing and sociable, contrasting with introverts who prefer solitude.
Step-by-step explanation:
According to Hans and Sybil Eysenck's theory of personality, the personality type characterized by sociability is known as extroversion. Individuals who are high on the trait of extroversion are typically outgoing, sociable, and find it easy to connect with others. In contrast, their counterparts high on the trait of introversion prefer solitude, engage less in social interactions, and often require alone time to recharge. The Eysencks proposed two main personality dimensions: extroversion/introversion and neuroticism/stability, with a later addition of a third dimension: psychoticism versus superego control.
