There are three kinds of egocentric speech: Echolalia, Monologue, and Social Monologues.
Hence, in egocentric speech there is no effort made to tailor the speech so that it can be understood by a particular listener.
In many instances also, since syncretistic thought is self centered, the speech is not even an effort to communicate but is made for the pure enjoyment of the speaker. There are three kinds of Egocentric Speech: Echolalia, Monologues and social (or dual) monologues. Echolalia is repeating sounds, words, phrases and/or sentences for the fun of saying it. Adults do it occasionally when they are bored or scared.
A Monologue is a running discourse. It usually occurs when a child is playing. Often it is just fragments of sentences that can be heard (see the notes).
