Leontiev
Leontiev was a psychologist who studied how our activities shape our development and identity. He believed that human consciousness and personality are formed through purposeful activities, like work, study, or social interactions. These activities are influenced by social and cultural contexts, and they, in turn, influence our mental processes. Essentially, Leontiev's theory emphasizes that we grow and change through meaningful actions within our environment, and understanding these activities helps explain how individuals develop their skills, knowledge, and sense of self over time.
