ABSTRACT
After the behaviourist theories came cognitive ones. The leading and most influential cognitive theorist in the West was Piaget, although Vygotsky’s work has been much more influential in Eastern Europe. We might have left Vygotsky until the next chapter, as his approach is also interactionist and similar in many ways to George Herbert Mead’s, but Piaget and Vygotsky both offer developmental theories. The one writer we look at in this chapter who writes from a specifically adult education background, Jack Mezirow, has almost no developmental element to his work.
