 Traditional versions of simulation theory typically describe simulation using expressions such as “imaginatively putting oneself in the other’s place”. How this metaphor is understood depends on the specific account. (A collection of papers exploring various versions of simulation theory can be found in Dokic &amp; Proust (eds.) 2002.) On many accounts, the projection is assumed to involve the subject’s imaginatively running mental processes “off-line” that are directly analogous to those being run “on-line” by the target (for example Goldman 1989). Whereas the “on-line” mental processes are genuine, the “off-line” mental processes are merely imagined. For example, a target that is deciding whether to eat sushi for lunch is running their decision-making processes “on-line”; and a subject that is simulating the target’s decision-making is running the analogous processes “off-line”—in part, by imagining the relevant mental states of the target. Recent empirical work in psychology has explored the accuracy of such projections (Markman, Klein, &amp; Suhr (eds.) 2009, section V; Saxe 2005, 2006, 2009.)
