Alexei Leont'ev

Alexei Leont'ev was a Russian psychologist who expanded on the ideas of Lev Vygotsky, focusing on understanding human activity and development. He emphasized that people's actions are shaped by their social context and goals, and that learning occurs through meaningful activities rather than isolated skills. Leont'ev highlighted the importance of collective social practices and tools in shaping individual cognition, viewing development as a process that involves both internal mental functions and external social interactions. His work helps explain how people acquire knowledge and skills through participation in cultural and social activities.
