There is considerable evidence that language comprehenders derive lexical‐semantic meaning by mentally simulating perceptual and motor attributes of described events. However, the nature of these simulations—including the level of detail that is incorporated and contexts under which simulations occur—is not well understood. Here, we examine the effects of first‐ versus third‐person perspective on mental simulations during sentence comprehension. First‐person sentences describing physical transfer towards or away from the body (e.g., “You threw the microphone,” “You caught the microphone”) modulated response latencies (...) when responses were made along a front‐back axis, consistent with the action‐sentence compatibility effect (ACE). This effect was not observed for third‐person sentences (“He threw the microphone,” “He caught the microphone”). The ACE was observed when making responses along a left‐right axis for third‐person, but not first‐person sentences. Abstract sentences (e.g., “He heard the message”) did not show an ACE along either axis. These results show that perspective is a detail that is simulated during action sentence comprehension, and that motoric activations are flexible and affected by the pronominal perspective used in the sentence.
