Explanation:

According to Vygotsky and Piaget, private speech is a type of self-talk that serves an intellectual function between ages 3 and 7, and a self-regulating function from age 7 on. Therefore, we can think of two types of private speech. None of them is directed towards other people, only to self, even though the private speech of younger children is performed out loud. It is from age 7 on that private speech becomes a silent, inner speech to self, focusing on self-guidance and regulation of one's own behavior.
