I don't know about that. First, let's not mistake the demands of one's position for one's personal preferences. Second, google found me this:

She breaks down presidential exchanges with the news media into four categories: primetime news conferences; news conferences held alone or jointly alongside a foreign head of state; brief Q-and-A sessions, which typically transpire in the Oval Office, the Cabinet Room, or similar settings; and one-on-one interviews.
Adding up those four categories, Kumar finds this president, through May 20, has faced reporters’ questions on 280 occasions in the first 485 days of his term. That compares with 275 such instances for George W. Bush, 454 for President Clinton, and 198 for George H.W. Bush.
While that total figure reflects almost exact parity between Obama and his immediate predecessor, a more detailed breakdown reveals a stark difference in the way the two men approached their interactions with reporters. Where George W. Bush held 186 brief Q&A's – the daily bread and butter for the White House press corps, particularly wire service reporters – and gave only 56 personal interviews, Obama has done almost exactly the opposite. He has held only 56 Q-and-As, and granted 188 personal interviews.
Unless I am mistaken, almost every description of an introvert mentions the preference for one-on-one communication, no?
