Thinking and speech

Here is a work that has become a classic of domestic psychology. The author himself, the founder of cultural and historical theory, Lev Semenovich Vygotsky, described it as a "psychological study of one of the most difficult, confusing and complex issues of experimental psychology, the question of the connection of thinking and speech."
He substantiated the novelty and revolutionaryness of his work in the following moments:
- the experimental establishment of the fact that the meanings of words develop in childhood, and the determination of the main steps in their development,
- the disclosure of the peculiar way of developing the scientific concepts of the child in comparison with his spontaneous concepts and the clarification of the basic laws of this development,
- the disclosure of the psychological nature of written speech as an independent function of speech and its attitude to thinking,
- the experimental disclosure of the psychological nature of internal speech and its attitude to thinking.
The book that you hold in your hands completely reproduces the last lifetime edition of L.S. Vygotsky, published in 1934.
The study is basic for students to study psychological faculties and many other humanitarian trends
