This commentary is an attempt to give a Vygotskian perspective on Carpendale's & Lewis's (C&L's) target article. The article uses ideas that are well familiar to Vygotsky's scholars. However, it develops these ideas further and raises important empirical questions about the role of social interaction in the development of social cognition. The article provides a fresh view on the old problems and frames themes traditional for the English-speaking developmental psychology into a broader international perspective.
