ABSTRACT
Chapter 6 reports about theoretical developments proposed on the basis of the case study’s observations (as well as prior theories and recent empirical research by other authors). It begins with a comparative overview of the different forms and modalities of representation encountered in the study, noting their interaction and chronological succession, the varied mediating roles assumed by gestures, and a discussion of representational heterogeneity and the challenge this poses for established theories in cognitive science. It then proceeds to discuss the role of metaphors for representational change, starting with a survey of the kinds of changes caused by metaphors, before discussing the question of where their source domains might have come from. This includes a discussion of the roles of task-unrelated routine behaviour and indirect control schemes for associative memory retrieval. Finally, it considers these activities might still be organised in problem spaces and comes to the conclusion that at least some if must be organised differently.
