According to Vygotsky, why do children talk to themselves?

Vygotsky was a Russian psychologist who believed that social interactions play a vital role in development.

According to him, learning occurs when children interact with people in society and the environment.

According to Vygotsky, children talk to themselves using private speech to assist their thinking and self-regulation. The concept of 'private speech' refers to speech directed toward the self without communicative intent toward others. Children use private speech to guide their actions by speaking aloud to themselves.
