For Orac: Ian commented that the "box" was vibrating as if alive, but that was about the extent of it. As Grinch Doctor stated, it was in "The Edge of Destruction" that really played up the idea that the TARDIS had a sense of self awareness independent of the Doctor. (It tried to warn the "crew" of the danger through "suggestion" as it could not seemingly "talk" to them directly. And it was the Doctor's realization of that fact that led him to become less self absorbed and start evolving into the personality that we recognize to this day.
Sincerely,
Bill
