 Here is our trite example. On the basis of observing John’s disgusted facial expression, Lisa comes to judge that John is having a disgust experience. How did she arrive at the formation of this judgment? Goldman’s answer is as follows. The observation of John’s disgusted facial expression triggered a disgust mirroring process in Lisa, resulting in Lisa’s undergoing a mirrored disgust experience (STAGE 1). This caused Lisa to introspect her simulated disgust experience and to categorize it as a disgust experience (STAGE 2) (the technical notion of introspection used by Goldman will be discussed in  section 4.4).  This, in turn, brought about the formation of the judgment John is having a disgust experience (STAGE 3). Given that, according to Goldman, mindreading events are identical to events of judging that someone else has a certain mental state, it is only this last stage of Lisa’s cognitive process that constitutes a mindreading event. On the other hand, the previous two stages were merely causal contributors to it. But mental simulation entirely took place at STAGE 1. This is why the Three-Stage Model is a version of the Causation View: according to the model, mental simulation events causally contribute to, but do not constitute, mindreading events.
