Having presented the evidence and described the mirror-image processes; the task is now to understand and to establish the nature and extent of what has been achieved.

Considering the matter of arousal in the creative process emphasized earlier, what is the evidence for such arousal and how does it function in created products? Are there other qualities of the mirror-image processes, beside their arousal function, that lead to the production of creations?
