Scenario:
Sharon is talkative and friendly to guests she has invited over for a dinner party. She mingles freely in the various social circles that have developed throughout her home. Her guests enjoy her carefree attitude and enjoy the time spent with her. When one of her guests decides to return the favor, Sharon arrives to discover she only knows her host. She quickly gets a drink and spends most of the night sitting in a chair tucked away in a corner, set away from the social interactions. At dinner, she keeps to herself and answers questions with no more than three words at a time. When dinner is over, she thanks her host and quickly leaves, avoiding saying farewell to any of the other guests.
Decide on two theorists associated with studying person-situation interactions and apply their theories to the scenario.
