Well, they say that the sonic is an extension of the TARDIS' technology, and that has always been unpredictable - seems like the sonic is extending this unpredictability!! Mine's ok for now....
It seems like everyone is having a say about 'psychic sonic', so I will say my part. Even if the eleventh (or twelfth) doctor does explicitly say that the sonic is 'psychic', we can use the theory that the sonic is an extension of the TARDIS' tech and say that becuase the TARDIS can communicate with people, so can the sonic. However, the method of communication could be subject to change.
I believe that Tennant listened to the slight variations in sound to know what the sonic was thinking (I.e. The sonic was talking to him). For me, Tennant's wasn't psychic. Maybe Smith's was. Both sonics can still COMMUNICATE with the user.
