Which of the following is labelled as the second self?

The device labelled the second self is the computer.

Sherry Turkle used the phrase for the way the computer becomes an extension and mirror of the user's mind.

It is called a second self because people project identity, thought and emotion onto their machines.

The telephone chiefly extends the voice across distance, not the self in this sense.

Radio and television are largely one-way broadcast media and do not carry this reflexive, personal identity.

Turkle developed the idea in her 1984 book The Second Self.
