The papers address memory in many contexts: in dance and under hypnosis, in social groups and with siblings, in early childhood and in the laboratory.

Clark (2001:154) argues: Much of what matters about human intelligence is hidden not in the brain, nor in the technology, but in the complex and iterated interactions and collaborations between the two ... The study of these interaction spaces is not easy, and depends both on new multidisciplinary alliances and new forms of modelling and analysis.
