Vygotsky’s Social Cognitivism
While Piaget attempted to study and explain learning in terms of the role of contradiction and equilibration,Vygotsky explained learning by means of dialogue (Fosnot 1996). Another key difference between their works is that while Piaget explored the development of logical thinking, Vygotsky focused on categorical perception, logical memory, conceptual thinking, and selfregulated attention (Gredler 1997, 269).
