 Now that we know what  REU  means, we can consider whether it fares better than  RES-2  in capturing the nature of the relation of mental simulation. It would seem so. Consider this hypothetical scenario. Lisa is seeing a yellow banana, and her visual experience has been generated by cognitive process V1, which has been implemented by the use of her visual mechanism. I am visualizing a yellow banana, and my visual image has been generated by cognitive process V2, which has been implemented by the reuse of my visual mechanism. Rosanna-the-Super-Reasoner is also visualizing a yellow banana, but her visual image has been generated by an information-rich cognitive process: a process drawing upon Rosanna’s detailed knowledge of vision and implemented by her incredibly powerful reasoning mechanism.  REU  correctly predicts that my visual image is a mental simulation of Lisa’s visual experience, but not vice versa. More importantly, it also predicts that Rosanna’s visual image does not count as a mental simulation of Lisa’s visual experience, given that Rosanna’s cognitive process was not implemented by the reuse of the visual mechanism. In this way,  REU  solves the problem faced by  RES-2  in distinguishing ST from TT.
