 Go back to the case in which Lisa was having a visual experience of a yellow banana, while I was having a visual image of a yellow banana. Our two mental states resembled one another, but different cognitive processes generated them: seeing in Lisa’s case, and visualizing in my case. Moreover, Lisa’s seeing was implemented by the use of the visual mechanism, while my visualizing was implemented by its reuse. According to PROC, the latter cognitive process, but not the former, was thus a simulation process.
