[Vygotsky Thought & Language 1934/1962] Lev Vygotsky (1896-1934) - Soviet Cognitive Psychologist

  • Primary architect of the Sociocultural Theory of Cognitive Development during the 1920s-1930s
    • Not well known in West until the 1960s-1980s because of the closed nature of the Soviet government
  • Child is partner in constant social interactions with parents, teachers, & older children
  • Cognitive skills develop in response to cultural resources, for example, language skills are taught in literate cultures via schools compared with non-literate cultures which rely upon conversation
  • Expertise is learned via apprenticeship with instructor helping student develop skill at the border between what is known & not known (Zone of Proximal Development or ZPD)
  • Language is the crucial element in cognitive development
  • Speech is first public and social. It is later internalized to become private speech (as spoken thoughts inside our heads) as young child gets older
