Lev Borisovich Itelson (1926-1974) lived little, but managed to do a lot. In particular, he was one of the first scientists to introduce cybernetic and mathematical methods into psychological science. His fundamental work & # 96; Lectures on General Psychology & # 96; entered the golden fund of Russian psychology. Brilliant in form, deep in content, it is absolutely not outdated despite the fact that it was created about 30 years ago. The proposed book is interesting and highly useful for teachers, graduate students, students, practical psychologists and all those who are interested in psychological science.
