Written by some of the world's leading academics and professionals in the field, this collection of essays brings together two complementary views on child development - the role of society and the role of cognitive growth.

Carpendale & Lewis's (C&L's) theory falls in with an existing set of theories that children's understanding of mind is collaboratively constructed in linguistically mediated social interaction. This social constructivist view needs to be clear about the complementary contributions of the child and of the social environment. I distinguish between the child's individual linguistic ability and the dyad's social communication, proposing that each makes a contribution to theory-of-mind development, differently balanced in different individuals.
