I'm an introvert and I voted for playing with my wife. I don't think you can just ratchet all those responses up to introversion. Often, people who believe they are introverted actually aren't (or maybe they are, but that isn't the primary reason for their social isolation). Other behavior factors such as shyness and social anxiety come into play very often.
