ABSTRACT
Chapter 4 introduces a task domain that has been developed to possess the properties the preceding chapters found lacking in most established work, namely iterated mental paper-folding. The chapter is divided into a detailed discussion of the task domain’s abstract properties followed by a discussion of how they might be mentally represented in terms of (inter alia) mental imagery, symbolic reasoning, and heterogeneous “mixtures” of the two, including a potential role for metaphors in enabling the interaction of different forms of knowledge.
