You're giving an important speech. Suddenly you hear yourself saying, "Now, where was I?" You have just engaged in self-talk and probably not for the first time. Nor are you alone.
According to Thomas Brinthaupt, Ph.D., assistant professor of psychology at Middle Tennessee State University, almost everybody talks to themselves. And no--we are not all crazy. It is unusual not to talk to yourself.
Self-talk serves a very important purpose. It is a means of self-regulation.
There are two kinds of self-talk: silent inner speech, when you think to yourself, "I've got to remember to go to the bank," and vocalized private speech, when you mumble a reminder to yourself. Self-talk can be used to remind people to run errands, prepare for speeches, or work through the steps of a process.
Depending on your level of self-esteem, self-talk can be either positive or negative. Folks who suffer from low self-esteem spend more time planning and going over what was already said. For those with higher self-esteem, self-talk is more positive and congratulatory. They are not preoccupied with thinking about what they should have said.
